Design websites with AI — open, local, yours.
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.
How it works
From prompt to published site
"Create a landing page with hero, features section, and contact form" — that's all it takes.
Open Silex Desktop
Connect your AI (Claude Code, OpenCode, or any MCP client)
Describe what you want
Refine visually in real time
Publish — clean HTML/CSS, host anywhere
Your AI, your choice
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.
Local first
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.
HTML first
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.
How AI talks to the editor
A standard protocol connects any AI to Silex
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.
Silex Desktop
A local app for visual web creation with AI — early prototype, looking for beta testers
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.
Landing Pages
"Create a landing page for a SaaS product with hero, features, pricing, and CTA"
Documentation sites
"Generate a docs site structure with sidebar navigation and search"
Portfolios
"Build a portfolio with project grid, about section, and contact form"
Client websites
"Create a small business site with services, testimonials, and contact form"
