Open-source AI pair programming inside your terminal and git repo
Chat with an AI assistant from your shell, have it propose and apply code edits to files in your working directory, and keep full control of the final diff.
Every accepted change becomes a real commit with an auto-written message, so you can inspect, amend, revert or branch AI edits with ordinary git commands.
Aider builds a structural map of your project so the model understands where relevant code lives and can work sensibly in large, multi-file codebases.
Connect hosted models from Anthropic, OpenAI, DeepSeek and others, or point Aider at a locally hosted model to keep code on your own hardware.
AI code review that runs your app on every pull request
TestDriver reviews every pull request automatically, reads the diff with its vision agent, and generates end-to-end tests straight from the PR content to prove the new behavior works.
Tests run your actual application in a real desktop sandbox—clicking, typing and reading the screen—so they catch runtime and visual bugs, not just code diffs.
When the UI shifts and a cached element no longer matches, the AI finds it again, updates the cache and continues, so tests survive redesigns without rewrites.
Once a test passes, TestDriver opens a fresh pull request with the generated Vitest test code committed, so coverage lands in your repo alongside the change it protects.
