Reason

Reason is an autonomous AI software engineer and cloud coding agent that ships pull requests.

Reason is an autonomous AI software engineer and cloud coding agent designed to handle software development tasks. Users connect GitHub, assign issues, and let the agent ship evidence-backed pull requests on autopilot. The system operates across two models and provides recordings on pull requests alongside a dashboard tracking metrics like AI spend per employee. It includes mobile support to start tasks and check progress from a phone. Reason outperforms Codex and functions as a specialized coding agent focused entirely on software engineering workflows.
