A free coding agent that writes, tests, and ships code, Lemon Code lets you describe a task and then shows the finished result running in a browser preview while also committing the edited files and new tests. It runs the commands, displays terminal output and passing tests, and keeps a change panel with edited files and commit history - for example, fixing a cart total, adding a test, running four tests and showing a corrected $66.00 total. It can run in a cloud workspace in-browser or as a Mac app on your machine, and you can choose to use built-in models or bring your own (Claude Code, Codex, Gemini CLI) with your own API key.
Lemon Code also automates workflows by connecting to over 1,500 apps (GitHub, Slack, Notion, Linear, Gmail, Jira, and many more). Once connected it can review pull requests, turn ready issues into pull requests and tests, post daily standups to Slack, triage and label new issues, prepare meeting briefs from calendar and email threads, and draft incident write-ups in Notion. Connectors are managed from a single screen for sign-in and keys, automations can run once or on a schedule, and the tool is offered free on Mac and in the browser with no required API key.
