Kata Code — Development skill for Claude Code

Kata Code

Kata Code is an "agent harness control surface". It enables control of the agents on your machine with a [web app](https://app.kata.sh) and an Electron desktop app.

Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, and OpenCode. If they're set up on your computer, Kata Code can control them.

Installation

[!WARNING] Kata Code currently supports Codex, Claude, Cursor, Grok Build and OpenCode. Install and authenticate at least one provider before use:

• Codex: install Codex CLI and run codex login
• Claude: install Claude Code and run claude auth login
• Cursor: install Cursor CLI and run agent login
• Grok Build: install Grok Build CLI and run grok login
• OpenCode: install OpenCode and run opencode auth login

Try it out (install-free)

The easiest way to test Kata Code is to run the server in your terminal (requires Node.js 22.16+, 23.11+, or 24.10+):

npx @kata-sh/code-cli@latest

This will launch Kata Code's backend on your machine as well as the local web app to control your agents.

Tip: Use `npx @kata-sh/code-cli@latest --help` for the full CLI reference.

Test a headless remote environment

Run a second, isolated server on your machine:

npx @kata-sh/code-cli@latest serve \
  --port 53210 \
  --base-dir ~/.katacode-headless-test

In the desktop app, open **Settings** → **Connections** → **Add environment** → **Remote link**, paste the printed pairing URL into **Host**, then click **Add environment**. Use `@nightly` instead of `@latest` when testing with the Nightly app.

To expose a headless Linux server through Kata Code Connect:

npx @kata-sh/code-cli@latest connect link --headless
npx @kata-sh/code-cli@latest serve
