A content management system (CMS) is software used to create, manage and publish digital content, most often websites, without hand-coding each page. This list covers 14 CMS products available in November 2026: open-source systems such as WordPress, Drupal and Joomla; hosted platforms such as Webflow and HubSpot Content Hub; headless systems such as Contentful, Sanity, Strapi and Storyblok; and enterprise digital experience platforms from Adobe, Sitecore and Optimizely.
Licences, plans and prices are drawn from each project's or vendor's own pages. The market has consolidated in 2026, with Salesforce completing its purchase of Contentful on 1 September.

What is a CMS
A content management system (CMS) is software that lets people create, edit, organise and publish digital content, typically web pages, without writing code for each change. A CMS separates content from presentation: editors work in an administrative interface, while templates or front-end code control how content appears. Most systems add user roles, workflow, versioning, media management and extension mechanisms such as plugins or modules.
CMS products fall into several groups. Traditional or coupled systems such as WordPress, Drupal and Joomla manage both content and the website's rendering. Headless CMS products such as Contentful, Sanity, Strapi and Storyblok store structured content and deliver it through APIs to any front end. Hosted website builders such as Webflow include a CMS within a design-and-hosting platform. Digital experience platforms such as Adobe Experience Manager, SitecoreAI and Optimizely add personalisation, testing, asset management and analytics for large enterprises. Adjacent categories include blogging platforms, website builders, digital asset management software and headless CMS software, each covered by separate lists.
History and market
Web content management emerged in the late 1990s as organisations moved beyond hand-coded HTML. Open-source systems followed: WordPress began in 2003 as a fork of b2/cafelog, and Joomla's copyright line runs from 2005, while Drupal grew a community the project now puts at more than one million contributors. Enterprise vendors built commercial platforms combining CMS with marketing tools, and in the late 2010s API-first headless products appeared to serve apps and multiple channels from a single content store.
The 2020s brought consolidation and a shift to cloud services and AI. Adobe moved AEM to a continuously updated cloud service and, after completing its acquisition of Semrush on 28 April 2026, announced plans to combine Semrush with AEM and Adobe LLM Optimizer. Salesforce agreed to acquire Contentful on 1 June 2026 and closed the deal on 1 September 2026. Sitecore now markets a SaaS platform named SitecoreAI, and Optimizely markets an "Agentic CMS". No market-size estimate from a named research firm was verified for this list.
Key features to compare
Architecture
Coupled systems are quicker to launch a single website; headless systems suit apps and multiple channels but require front-end development. Several products, including Drupal, AEM and SitecoreAI, support both modes.
Licensing and hosting
Open-source systems (WordPress, Drupal, Joomla, Strapi, Payload) avoid licence fees but need hosting and maintenance; SaaS products include hosting and updates.
Editor experience
Visual editing differs widely: Webflow, Storyblok and SitecoreAI offer in-context page building, while Sanity's studio is configured in code.
Content modelling
Structured content types, fields and references determine how reusable content is across channels; Drupal, Craft and the headless products are strongest here.
Users, roles and workflow
Seat limits and role counts vary by plan, for example two roles on Sanity's free plan and review workflows only on Strapi Enterprise.
AI features
Sanity includes Content Agent credits, SitecoreAI includes AI translation and agents, and Optimizely offers pre-built AI agents.
Integrations and ecosystem
WordPress has the largest plugin ecosystem; HubSpot Content Hub connects natively to HubSpot CRM; Optimizely connects to Salesforce and Marketo.
Security and compliance
Enterprise plans add SSO, audit logs and SLAs, for example SAML SSO on Sanity Enterprise and Craft Enterprise and a SOC 2 report on Strapi Enterprise.
Pricing models
CMS pricing follows four main models. Free open-source software (WordPress, Drupal, Joomla, Strapi Community, Payload) shifts costs to hosting, development and maintenance. Per-seat SaaS pricing is used by Sanity (US$15 per seat a month on Growth) and HubSpot Content Hub Starter (from US$7 per seat). Tiered SaaS plans with included seats and usage are used by Storyblok (US$99 and US$349 a month), Webflow (US$25 a month for CMS sites) and HubSpot Professional (from US$450 a month). Per-project licences are Craft's model: US$279 or US$399 per site plus US$99 a year for updates.
Enterprise digital experience platforms (AEM, SitecoreAI, Optimizely) and the upper tiers of most headless vendors are quote-based, and their total cost usually includes implementation by partners.
How to choose
Small businesses and individual sites usually choose WordPress (self-hosted or WordPress.com) or Webflow for design-led marketing sites. Organisations already on HubSpot gain the most from Content Hub's CRM integration. Public sector, universities and complex multilingual sites commonly use Drupal, with Joomla as a lighter alternative. Developer-led teams building apps or multi-channel products should compare Sanity, Strapi, Payload and Contentful, with Storyblok when marketers need visual editing. Agencies building bespoke client sites often prefer Craft CMS or WordPress. Large enterprises running many brands and regions, especially with personalisation needs, typically evaluate Adobe Experience Manager, SitecoreAI and Optimizely, and should factor in implementation partner costs.
Methodology
Products were included if they are actively maintained content management systems available to new customers. They were ordered by breadth of applicability (how many kinds of organisation can use them), licensing openness and cost of entry, documented capabilities and transparency of pricing. Open-source general-purpose systems rank first, followed by hosted platforms, headless systems and enterprise digital experience platforms, which serve narrower but larger customers. Facts come only from project and vendor pages opened in November 2026. No usage-share estimates, user ratings or test scores were used.
The list
1
Open-source GPL CMS with the largest theme and plugin ecosystem
Best for: General-purpose websites of almost any size
WordPress is open-source content management software written in PHP and using a MySQL-compatible database such as MariaDB. It started in 2003 when Mike Little and Matt Mullenweg forked the b2/cafelog blogging tool, and it is licensed under the GNU GPL version 2 or later, which allows anyone to run, modify and redistribute it. The project is developed by a worldwide community and powers what it describes as millions of sites.
WordPress began as blogging software but is used today for company websites, publications, membership sites and online stores, extended through themes and plugins. It can be self-hosted at no licence cost or run as a hosted service: WordPress.com, for example, offers a free plan and paid tiers from US$4 a month on yearly billing, with plugin installation from the Personal plan upwards. Its block editor and large pool of developers make it the default general-purpose CMS for small and mid-sized organisations. The disadvantages are well documented: plugin quality and security vary, performance depends on hosting and configuration, and complex sites can accumulate technical debt.
Key features
- Open-source GPL licence
- Themes and plugins for extension
- Self-hosted or hosted via WordPress.com
- 60,000+ plugins installable on WordPress.com paid plans
- Worldwide contributor community
Pricing
Software free under the GPL; hosting paid separately. Hosted WordPress.com plans: Free; Personal US$4/month yearly (US$9 monthly); Premium US$8; Business US$25; Commerce US$45; WordPress VIP quote-based.
- First released
- 2003
- Licence
- GPLv2 or later
- Pricing
- Free software; hosted plans from US$4/month (WordPress.com, yearly)
Strengths
- Largest ecosystem of extensions and developers
- No licence cost
- Highly portable between hosts
- Suitable from blogs to large sites
Limitations
- Plugin security and quality vary
- Maintenance burden when self-hosted
- Performance depends on hosting
- Complex sites can become hard to maintain
2
Enterprise-grade open-source CMS supported by the Drupal Association
Best for: Complex, multilingual or high-security institutional sites
Drupal is an open-source content management system distributed under the GNU GPL with no licensing fees; the project states that it "will always be free". The Drupal Association, a non-profit, supports the project, and the community, which the project describes as one of the largest in open source, counts more than one million contributors. Drupal is a registered trademark of its founder, Dries Buytaert.
Drupal is known for structured content modelling, granular permissions, multilingual support and scalability, which have made it common among governments, universities and large organisations. To address its reputation as a developer-centric tool, the project now offers Drupal CMS, a packaged version intended to put Drupal "into the hands of marketers, designers and content creators", with a trial and a user guide. Drupal's limitations are a steeper learning curve than WordPress, a smaller pool of developers, and higher implementation costs for custom sites.
Key features
- GPL licence with no licensing fees
- Drupal CMS packaged edition for marketers
- Drupal CMS trial and user guide
- Non-profit Drupal Association support
- Community of 1,000,000+ contributors
Pricing
Free and open source under the GPL, with no licensing fees. Hosting and implementation are paid separately.

Strengths
- No licence cost
- Strong content modelling and permissions
- Proven at large institutional scale
- Large contributor community
Limitations
- Steeper learning curve
- Fewer developers than WordPress
- Custom builds can be expensive
- Major upgrades require planning
3
Community-run open-source CMS now on version 6
Best for: Community and small-business sites wanting built-in multilingual features
Joomla! is a free, open-source content management system available under the GPL, with its project trademarks and assets held by Open Source Matters, Inc. The project states that it powers millions of websites and that thousands of extensions are available, and its current major release line is Joomla! 6.
Joomla is often described as sitting between WordPress and Drupal in complexity, with a component-based architecture and many features in its core. It is used for community sites, small-business websites and portals. The trade-offs are a smaller extension and developer ecosystem than WordPress and less presence in the enterprise and headless markets, which can make hiring and long-term support harder.
Key features
- Thousands of extensions
- Free and open source under the GPL
- Joomla! 6 release line
- Governed by Open Source Matters, Inc.
Pricing
Free and open source under the GPL. Hosting and extensions may be paid.
- Licence
- GPL
- Organisation
- Open Source Matters, Inc.
- Current major version
- Joomla! 6
- Pricing
- Free
Strengths
- No licence cost
- Many features built into the core
- Established community governance
Limitations
- Smaller ecosystem than WordPress
- Less adoption in enterprise and headless projects
- Fewer developers available
4
Visual development platform with a built-in CMS and hosting
Best for: Marketing sites built by design teams
Webflow is a hosted visual development platform that lets designers build responsive sites with CSS-level control and manage structured content in the Webflow CMS. Site plans start with a free Starter plan on a webflow.io domain with limited CMS use. The Basic plan (US$15 a month billed yearly) adds a custom domain but no CMS, and the Premium plan (US$25 a month billed yearly), marked as new in 2026, adds the CMS, site search, code components and selectable bandwidth.
Organisation-level platform plans start with Team at US$2,500 a month on an annual contract, adding localisation, AEO agents, publishing workflows, an activity log and enhanced security; Enterprise adds granular permissions, custom roles and dedicated account management. Webflow is widely used by marketing teams that want to ship landing pages without developers. Its CMS is less flexible than headless products for multi-channel delivery, and the move from site plans to platform plans is a large price step.
Key features
- Visual designer with responsive controls
- Webflow CMS collections
- Managed hosting and bandwidth tiers
- Code components
- Webflow AI and MCP server
- Localisation and AEO agents on Team
Pricing
Starter free; Basic US$15/month billed yearly (no CMS); Premium US$25/month billed yearly (CMS); Team US$2,500/month (annual contract); Enterprise by quote.
- Pricing
- Free Starter; CMS from US$25/month (yearly); Team US$2,500/month
Strengths
- Strong design control without code
- Hosting included
- Free plan for prototyping
Limitations
- CMS absent from Basic
- Large price jump to Team
- Less suited to multi-channel content
- Vendor lock-in to Webflow hosting
5
CMS integrated with HubSpot's CRM and marketing tools
Best for: Companies already using HubSpot CRM and marketing tools
Content Hub is HubSpot's content management product, combining a hosted website and blog CMS with the company's CRM, so that pages can be personalised using contact data and leads flow directly into sales and marketing tools. It is offered in four tiers. A free tier covers up to two users and requires no credit card; Starter starts at US$7 per seat per month (listed alongside US$20 per seat); Professional starts at US$450 a month with three core seats; and Enterprise starts at US$1,500 a month with five core seats. Plans include HubSpot Credits, from 500 on Starter to 5,000 on Enterprise.
Content Hub is best for organisations already using HubSpot's CRM, marketing or sales products. Outside that ecosystem it is expensive relative to open-source CMSs, Professional and Enterprise require annual commitments, and the hosted-only model limits infrastructure control.
Key features
- Hosted website and blog CMS
- CRM-based personalisation
- HubSpot Credits for AI features
- Free tier for two users
- Per-seat pricing on Starter
Pricing
Free (two users). Starter from US$7/seat/month (new customers; US$20 standard). Professional from US$450/month with three core seats, extra seats from US$45. Enterprise from US$1,500/month with five core seats, extra seats from US$75. Professional requires an annual commitment.
- Pricing
- Free; Starter from US$7/seat/month; Professional from US$450/month; Enterprise from US$1,500/month
Strengths
- Tight CRM integration
- Free entry tier
- Managed hosting and security
Limitations
- Expensive at Professional and Enterprise
- Annual commitment on higher tiers
- Best value only inside HubSpot's ecosystem
- Starter discount for new customers only

API-first headless content platform, owned by Salesforce since September 2026
Best for: Enterprises delivering structured content to many channels
Contentful is a hosted, API-first composable content platform in which teams model content as structured entries delivered to websites, apps and other channels through APIs. Salesforce announced a definitive agreement to acquire Contentful on 1 June 2026 and, according to an editor's note on its announcement, closed the acquisition on 1 September 2026; financial terms were not disclosed.
Contentful is one of the best-known headless CMS vendors, used mainly by larger organisations running content across several digital properties and regions. Its pricing page could not be accessed during this review because of rate limiting, so plan prices are not given here. As a headless platform it requires developers to build and maintain the front end, and its future packaging is likely to be shaped by integration with Salesforce's products.
Key features
- Structured content modelling
- Content delivery and management APIs
- Multi-channel delivery
- Composable architecture
Pricing
Pricing page not accessible at review time; see the vendor. Acquisition by Salesforce closed 1 September 2026.

Headless content platform with a customisable studio and free tier
Best for: Developer-led teams needing flexible content models
Sanity is a headless content platform whose editing interface, Sanity Studio, can be customised in code, with content stored in a hosted "Content Lake" and queried through APIs. Its free plan allows up to 20 seats, two permission roles, two public datasets, 10,000 documents and 100 GB of assets and bandwidth, and includes Content Agent with 1,000 AI credits a month, unlimited content types and locales, and live previews.
The Growth plan costs US$15 per seat a month for up to 50 seats, with five roles, private datasets, 25,000 documents and pay-as-you-go usage, plus add-ons such as dedicated support (US$799 a month) and extra datasets (US$999 each). Enterprise adds SAML SSO, an uptime SLA and custom quotas. Viewer seats are free on all plans. Sanity is favoured by developer-led teams that need flexible content models. Costs can rise quickly with add-ons, and like all headless systems it requires front-end development.
Key features
- Customisable Sanity Studio
- Structured content with APIs
- Live previews
- Content Agent AI (1,000 credits on free)
- Unlimited content types and locales
- Free viewer seats
Pricing
Free: up to 20 seats, 10,000 documents. Growth: US$15 per seat per month (up to 50 seats), 25,000 documents; add-ons dedicated support US$799/month, increased quota US$299/month, extra dataset US$999/month. Enterprise custom.
- Pricing
- Free (20 seats); Growth US$15/seat/month; Enterprise custom

MIT-licensed open-source headless CMS with self-hosted and cloud options
Best for: Developers wanting an open-source self-hosted headless CMS
Strapi is an open-source headless CMS built in JavaScript/TypeScript and released under the MIT licence. Developers define content types, and Strapi generates REST and GraphQL APIs and an admin panel. The self-hosted Community edition is free forever with core features, unlimited usage and community support.
The self-hosted Growth plan costs US$45 a month for three users, with additional users at US$15 each and basic support; Enterprise, priced through sales, adds SSO, review workflows, audit logs, a SOC 2 report and standard support. A separate Strapi Cloud offering provides managed hosting on its own price list. Strapi suits developers who want an open-source, self-hosted headless CMS with full control of data. It requires infrastructure management when self-hosted, and features such as SSO and review workflows sit behind the paid Enterprise plan.
Key features
- Content-type builder
- Auto-generated REST and GraphQL APIs
- Admin panel
- Self-hosted or Strapi Cloud
- SSO and audit logs on Enterprise
Pricing
Self-hosted: Community free; Growth US$45/month (3 users, extra users US$15/month); Enterprise via sales. Strapi Cloud priced separately.
- Licence
- MIT
- Pricing
- Community free; Growth US$45/month; Enterprise quote-based
Strengths
- Permissive MIT licence
- Free self-hosted edition with unlimited usage
- Full data control
Limitations
- Self-hosting requires DevOps work

- Front end must be built separately
9
Headless CMS with a visual editor for marketers
Best for: Headless projects where marketers need visual editing
Storyblok is a headless CMS from Storyblok GmbH that pairs API-first delivery with a visual editor showing content in the context of the page, addressing a common complaint that headless systems are hard for marketers to use. The Starter plan is free for testing and personal projects with one included seat (maximum two) and no credit card required.
Growth costs US$99 a month (US$90.75 billed annually) with five seats, Growth Plus US$349 a month (US$319.91 annually) with 15 seats, and the Premium and Elite tiers are sold through sales. Storyblok suits organisations that want headless flexibility with a marketer-friendly editor. Seat limits on lower tiers are restrictive for large teams, and enterprise features are not priced publicly.
Key features
- Visual editor with in-context preview
- Headless API delivery
- Component-based content blocks
- Free Starter plan
- Premium and Elite enterprise tiers
Pricing
Starter free (1–2 seats). Growth US$99/month or US$90.75/month annually (5 seats, max 10). Growth Plus US$349/month or US$319.91 annually (15 seats). Premium and Elite custom.

10
Developer-friendly PHP CMS sold per project
Best for: Agencies building custom client websites
Craft CMS is a self-hosted PHP content management system known among agencies for flexible content modelling and a clean control panel. It uses an unusual per-project licence. The Solo edition is free for a site built for oneself and includes one user account; Team costs US$279 per project with up to five users; Pro costs US$399 per project with unlimited users and a branded control panel. Both paid editions include one year of updates, after which updates cost US$99 a year.
Team and Pro licences are free when the site is hosted on Craft Cloud, the vendor's managed hosting, and verified non-profits receive a 15% discount on licence fees. Enterprise adds SAML SSO and a custom licence agreement. Craft suits agencies building bespoke marketing sites for clients. It has a smaller plugin ecosystem than WordPress, and the Solo edition is not intended for client work.
Key features
- Custom fields and content modelling
- Per-project licensing
- Branded control panel on Pro
- Free licences on Craft Cloud hosting
- SAML SSO on Enterprise
Pricing
Solo free (one user). Team US$279 per project (up to five users); Pro US$399 per project (unlimited users); one year of updates included, then US$99/year. Enterprise custom. 15% non-profit discount on licence fees.
- Pricing
- Solo free; Team US$279/project; Pro US$399/project
- Renewal
- US$99/year for updates
Strengths
- One-off licence instead of subscription
- Flexible content modelling

11
Open-source, Next.js-native headless CMS and application framework
Best for: TypeScript and Next.js engineering teams
Payload is an open-source framework and headless CMS that installs directly into a Next.js application, providing "a full backend" inside the developer's app, including an admin panel and APIs. The project emphasises ownership of what developers build, and its code-first configuration appeals to TypeScript teams who want the CMS and the website in one codebase.
Payload is free to self-host; the vendor directs enterprise buyers to a demo and its pricing link leads to a getting-started page rather than a published price list. It is best suited to engineering teams building custom applications and websites on Next.js. Non-technical teams will find it less accessible than hosted CMSs, and the lack of published commercial pricing makes budgeting for support harder.
Key features
- Installs inside a Next.js app
- Code-first configuration
- Admin panel and APIs
- Open-source framework
Pricing
Open source and free to self-host. Enterprise options via demo; no public price list.
- Licence
- Open source
- Pricing
- Free self-hosted; enterprise via demo
Strengths
- CMS and front end in one codebase
- Open source
- Strong fit for TypeScript teams
Limitations
- Developer-only setup
- No published commercial pricing
- Smaller ecosystem than older CMSs
12
Adobe's enterprise CMS and DAM, available as a cloud service
Best for: Large enterprises with multi-brand, multi-region estates
Adobe Experience Manager (AEM) is Adobe's enterprise content management platform for websites and digital assets. Its cloud version, AEM as a Cloud Service, provides cloud-native operations through Cloud Manager, a CI/CD framework with code-quality gates, a built-in CDN, automatic updates up to several times a month and autoscaling with no downtime for authoring or delivery. AEM Sites and AEM Assets are documented as separate capabilities.
Adobe is extending AEM into AI search: when it completed the Semrush acquisition on 28 April 2026, Adobe said Semrush would be combined with Adobe Experience Manager, Adobe LLM Optimizer and other products for SEO and generative engine optimisation. AEM is aimed at large enterprises with complex, multi-brand estates and existing Adobe investments. It is sold through quotes, requires specialist implementation partners and is among the most expensive CMS options.
Key features
- Cloud Manager CI/CD
- Built-in CDN
- Automatic continuous updates
- Autoscaling
- AEM Sites and AEM Assets
- Integration with Adobe LLM Optimizer and Semrush

Best for: Enterprises needing CMS plus personalisation in one SaaS platform
SitecoreAI is Sitecore's cloud-native software-as-a-service platform combining content management, personalisation, customer data and AI.

Sitecore also reports AI visibility insights powered by Scrunch, which it describes as a Sitecore company, and states that AI features are included natively rather than as paid add-ons. The platform targets large enterprises, especially those with existing Sitecore installations. Pricing is not published, and migration from older Sitecore products to the SaaS platform is a significant project.
Key features

Agentic CMS with built-in AI agents and experimentation heritage
Best for: Enterprises combining CMS, AI agents and experimentation
Optimizely's CMS, marketed as an "Agentic CMS", is an enterprise content platform with front-end hosting, multi-site and multi-channel management, edge delivery, interactive preview, content modelling, semantic search and an embedded DAM. It includes pre-built AI agents and "virtual teammates" that draft content, translate pages, optimise for SEO and generative search, and monitor performance, with approvals built in.
The platform connects to tools such as Salesforce, Figma and Marketo through the Optimizely Connect Platform, and the vendor says it is trusted by more than 10,000 brands. Optimizely packages every plan individually rather than publishing prices. It suits enterprises that want CMS, experimentation and AI agents from one vendor. Like other enterprise suites, it involves sales-led pricing and implementation partners.
Key features
- Multi-site and multi-channel management
- Edge delivery and front-end hosting
- Pre-built CMS AI agents
- Embedded DAM
- Semantic search
- Optimizely Connect Platform integrations

Frequently asked questions
What is the most popular CMS?
WordPress is the most widely used CMS; the project describes itself as powering millions of sites and has the largest ecosystem of themes, plugins and developers. Drupal and Joomla are other long-established open-source options, while Webflow, HubSpot and headless products such as Contentful and Sanity are common in specific segments.
What is the difference between a CMS and a headless CMS?
A traditional CMS stores content and also renders the website using templates. A headless CMS only stores and manages structured content, delivering it through APIs to any front end, such as a website, mobile app or kiosk. Headless systems are more flexible across channels but require developers to build the presentation layer.
Which CMS is best for small businesses?
Small businesses typically choose WordPress for its low cost and large ecosystem, Webflow for visual design control with hosting included, or HubSpot Content Hub's free or Starter tiers if they use HubSpot's CRM. Hosted website builders such as Wix and Squarespace are simpler alternatives for very small sites.
Is WordPress a good CMS for enterprises?
WordPress is used by many large organisations, often through managed hosting such as WordPress VIP, which is quote-based. Enterprises with complex workflows, many brands or personalisation needs often evaluate Drupal or digital experience platforms such as Adobe Experience Manager, SitecoreAI and Optimizely instead.
Are open-source CMSs really free?
The software is free to use under licences such as the GPL (WordPress, Drupal, Joomla) or MIT (Strapi), but hosting, security maintenance, development and paid extensions still cost money. Some vendors also sell paid editions, such as Strapi Growth at US$45 a month for three users.
Who owns Contentful?
Salesforce. It announced a definitive agreement to acquire Contentful on 1 June 2026 and states that the acquisition closed on 1 September 2026. Financial terms were not disclosed in the announcement.
