Reason

What it does

Reason is an autonomous software engineer. Connect a GitHub or GitLab repository, hand it an issue or a task, and it writes the code, runs the tests and opens a pull request with recordings, logs and a diff ready for review. It can run in Reason's cloud, on your own computer, or on a server you share, and you can follow and steer each run from the web or the terminal.
