Silex — the visual builder for static sites
The web belongs to everyone. Silex is a free/libre visual website builder — no lock-in, no subscription, no tracking. Design visually, export clean HTML/CSS, host anywhere.

Why Silex?
Most no-code tools lock you in: proprietary formats, forced hosting, subscriptions. Silex is different.
- Your data is yours — standard HTML/CSS output, export everything, host anywhere, leave anytime
- Real web skills — everything you learn in Silex (HTML, CSS, JAMstack) is transferable knowledge
- Community-owned — maintained by Silex Labs, a non-profit recognized as being of general interest. No investors, no exit strategy, transparent finances
- Free forever — always free software (AGPL), all features included, no premium tier
"The only open source alternative to Webflow." — "The most powerful and graphically precise website builder that I have experienced."
Who is Silex for?
- Web agencies — visual workflow, static output, scale client work without scaling your team
- WordPress developers — visual frontend, content from WP via GraphQL, ditch the theme layer
- Freelance webdesigners — create client sites without code, export standard HTML, host anywhere
- No-code developers — go beyond Wix/Squarespace with full CSS control and no vendor lock-in
Features
- GrapesJS-based visual editor — drag-and-drop page building with HTML, CSS, and JS editors
- Static HTML output — fast, secure, easy to host anywhere
- CMS integration — bind components to WordPress, Strapi, Squidex, or any GraphQL API
- 11ty compatible — generate static sites from Silex templates, deploy with CI/CD
- Desktop app (alpha) — work offline, no account needed, AI-ready with built-in MCP server. Built with Tauri for Windows, macOS, Linux. Download it or follow progress.
- Plugin system — extend with server and client plugins in JS/TS
- SEO tools — meta tags, Open Graph, per-page settings
- Self-hosting — Docker, Node.js, or one-click deploy on CapRover
Quick start
Use it online — v3.silex.me (free, requires a GitLab account for storage)
Desktop app (alpha) — download for Windows, macOS or Linux. Work offline, no account needed.

AI / Vibe coding
Design websites with AI — open, local, yours. Learn more
The upcoming Silex Desktop app will let you create and transform sites through prompts: describe what you want, see it built live, refine the design in real time, publish clean HTML/CSS anywhere.
Silex uses MCP (Model Context Protocol), an open standard — so you choose your AI. Run a local model with Ollama for full privacy, or use any MCP-compatible tool: OpenCode, Goose, Claude Code, etc. The MCP server is optimized for small local models (7B+).
See the vibe coding roadmap for what's coming (prompt library, examples cookbook, best practices guide — contributions welcome).
MCP setup (for developers)
Once Silex Desktop is running, connect your AI tool to:
http://localhost:6807/mcp
OpenCode — add an MCP server in your config file with URL http://localhost:6807/mcp.
Goose — add a remote server in your profile config with endpoint http://localhost:6807/mcp.
Claude Code — claude mcp add --transport http silex http://localhost:6807/mcp
Any other MCP client — use a Streamable HTTP transport pointed at the same URL.
