Reason
Autonomous cloud coding agent: connect GitHub, assign issues and get evidence-backed pull requests.
Reason is an autonomous AI software engineer and cloud coding agent from a Y Combinator-backed team. You connect GitHub and assign issues, and it splits work across subagents, tests its changes and opens pull requests with evidence such as recordings and passing checks. It runs on the web, desktop, terminal, Slack and mobile, with zero data retention and SOC 2.
