Lemon Code: a free coding agent that runs in your browser

We built Lemon Code because we wanted a coding agent that just runs anywhere. It works entirely in your browser (and on Mac): give it a task and it writes, runs, and tests code with a live preview, changed files, and terminal output you can inspect as it goes.

Beyond single tasks, it runs automations across 1,500+ app connectors and MCP servers: review PRs on a schedule, turn issues into pull requests, post standup summaries, triage tickets, and more.

It is free. No API key needed to start, and if you prefer you can bring your own Claude Code, Codex, or Gemini setup.

We are the team behind it. Tell us what breaks.
