Slab Review: Pricing, Pros, Cons & Alternatives

Overview

Slab is an internal knowledge base and wiki founded in 2016 and run as a fully remote company. Its about page names Asana, Fivetran and Vox Media among the companies that use it as a source of truth^[23]. Slab concentrates on the internal-wiki use case: posts organised into topics, a clean editor, content verification and a unified search that also covers content held in connected tools.

Slab’s free plan is unusually complete. It supports up to 10 users with unlimited posts and topics, real-time collaboration, verification, unified search, AI capabilities, single sign-on and 10 standard integrations, though attachments are limited to 10 MB and version history to 90 days. The Startup plan at $6.67 per user per month (billed annually) removes the user cap and adds private topics, AI Autofix and a year of version history; Business at $12.50 adds custom domains, AI Ask and AI Predict, SAML SSO, SCIM, a GraphQL API, webhooks and an uptime SLA. Enterprise requires at least 100 users^[22].

Slab’s limitations are scope and extensibility. It does not offer the public help-centre features of Document360 or Zendesk, and premium integrations are capped on Business. Monthly prices are not displayed on the pricing page. The Startup plan is free for qualifying non-profit and educational users, and the company offers a 30-day money-back guarantee^[22].
