Kition Design · Design Cluster

An experimental HTML kit with a source editor, a shared Rust/WASM renderer and PNG output. HTML, CSS and bounded JavaScript run against the same document. Browser compatibility is still incomplete.

Under construction

This planet is still in Preview. The scaffolding is real: things here work, but expect rough edges and changes.

  • Kition

    by Kition

    Desktop AI workspace for connected documents, structured tables, editable designs, whiteboards, visual workflows and reviewable AI agents.

What your AI can do here

These are real commands from this kit’s engine. An agent sends them over the Kit Harness Protocol and gets the edited file back.

  • html.setSourceReplace the HTML source

Use with your AI

Kition ships an MCP server for its kits. Run it over stdio against a folder, without the app open, and your agent gets tools like html_inspect, html_run and html_check for every kit.

# Claude Code
claude mcp add kition -- kition-kits-mcp --workspace /path/to/your/folder

# Any MCP client (mcpServers config)

  "mcpServers": {
    "kition": {
      "command": "kition-kits-mcp",
      "args": ["--workspace", "/path/to/your/folder"]
    }

The kition-kits-mcp binary comes with Kition. Without a licence key it runs in development and evaluation mode.

Questions

Is Kition html free?

Yes. Kition is open source under Apache-2.0 and the software is free. There are no personal subscriptions, memberships or ads; you only pay for AI compute if you choose hosted AI.

Can my AI agent use Kition html?

Yes. Every Kition kit speaks the Kit Harness Protocol (KHP), so an agent can open a file, run commands such as html.setSource, and save the result. MCP connects AI to tools; KHP lets AI operate professional software.

Which files does Kition html work with?

Kition html saves .html, .htm.

Is Kition html finished?

Not yet. Kition html is in Preview: it works, but it is still being built and may change.
