Webstudio

Webstudio is an advanced open-source visual website builder and Webflow alternative that lets designers and developers build fast, maintainable websites using modern web standards without writing code. It offers full CSS editing, CSS Grid and Flexbox layout, scroll-driven animations, design tokens, a CMS that connects to any HTTP API (Supabase, Airtable, WordPress, Notion, Hygraph, Baserow), webhook forms, and one-click publishing to Webstudio's cloud (Cloudflare) or self-hosting on Vercel, Netlify, Cloudflare Pages, or Docker. Its developer surface is agent-native: the `webstudio` CLI links, syncs, builds, audits, and publishes projects, and ships a first-party MCP server that exposes the Project's native visual-builder model to AI clients (Claude, Codex, Cursor, VS Code). Backed by Seedcamp.

Webstudio is profiled on the APIs.io network. Tagged areas include Company, Website Builder, No-Code, Visual Development, and Web Design.

Webstudio’s developer surface includes documentation, getting-started guide, engineering blog, support, pricing, signup flow, changelog, and 11 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/webstudio: open an issue to ask a question, or submit a pull request to add artifacts.
