Describe what you want, see it built live. A landing page, a portfolio, a client site — AI handles the code, you refine the design. Everything stays on your machine, outputs clean HTML/CSS.
A free/libre project by Silex Labs, a nonprofit since 2003.
"Create a landing page with hero, features section, and contact form" — that's all it takes.
Open Silex Desktop
Connect your AI (Claude Code, Goose, OpenCode, or any MCP client)
Describe what you want
Refine visually in real time
Publish — clean HTML/CSS, host anywhere
Silex doesn't bundle a specific AI. The MCP server is the interface — plug in whatever tool you prefer. OpenCode, Claude Code, local models via Ollama, or any MCP-compatible client.
→ No vendor lock-in. Your tools, your choice.
Your data stays on your machine. The app works offline. No account required. The MCP server runs locally — nothing leaves your computer unless you choose to publish.
→ Privacy by default. Work anywhere, even offline.
What the AI generates is the same HTML/CSS you'd write by hand. Inspect it, edit it, learn from it. Your skills transfer outside Silex.
→ Real web skills. Portable output.
AI is everywhere. The question is no longer whether to use it, but how. Silex Desktop runs on consumer hardware, no GPU, no cloud dependency. Small language models are enough for web design. Less compute, less energy, more accessible. You don't need the biggest model to build a good site.
Silex includes a bridge between AI tools and the visual editor. This bridge uses MCP (Model Context Protocol) — an open standard that lets AI assistants interact with applications.
Through this bridge, any compatible AI tool can:
Create and edit pages, content, and styles
Read the current document structure
Manage assets and data sources
Trigger builds and previews
As the AI ecosystem evolves, Silex adapts — not locked to one provider or one model.
Works offline, no account needed
Built-in AI bridge (MCP server)
Local file storage — your data stays yours
Publish to a folder — clean HTML/CSS, host anywhere
Windows, macOS, Linux
This is an early prototype. We ship fast, listen to feedback, and fix what matters. Your input directly shapes the tool.
"Create a landing page for a SaaS product with hero, features, pricing, and CTA"
"Generate a docs site structure with sidebar navigation and search"
"Build a portfolio with project grid, about section, and contact form"
"Create a small business site with services, testimonials, and contact form"
