Types of web development company
Platform specialists focus on one content management or commerce system. WordPress is the most common specialism in this list: Fueled's 10up practice, Human Made, WebDevStudios, rtCamp, Big Bite and XWP all concentrate on it, and several hold partner status with WordPress VIP. Elogic Commerce specialises in ecommerce platforms instead. Design-led studios such as Instrument, Clay, Ramotion and Huge combine websites with branding and product design.
App-focused engineering firms are covered in a separate list of app development companies and are not repeated here.
Methodology
Companies were included if they build websites or web applications for clients, operate under their current name and domain in November 2026, and publish an about page that could be opened and checked. They are ranked by the headcount each publishes on its own website, largest first. Self-reported figures such as '70+' are reproduced as published and placed above an exact figure of the same number. Companies that publish no headcount are placed after those that do, ordered by founding year, earliest first.
Headcount measures delivery capacity, not quality. Client names are given only where a company names them on its own website. No review-site ratings, testimonials from third-party marketplaces or prices were used; all companies listed quote prices on request. Valtech, Lullabot, Four Kitchens and Lounge Lizard were considered but excluded because a headcount or founding year could not be verified from their own pages.
