About Reason

Reason is an autonomous software engineer and AI coding agent designed to take ownership of real engineering work, from researching codebases and fixing bugs to implementing features and verifying results. It works across connected repositories, local computers, and cloud environments, allowing developers to delegate tasks without interrupting their workflows. The agent can explore codebases, trace call paths, reproduce failures, edit files, run tests, and produce verified pull requests for human review. Its research capabilities provide evidence-backed findings with citations linking directly to source files and lines, while repository memory preserves knowledge for future sessions. Reason supports parallel subagents, isolated workspaces, scheduled sessions, and automated workflows for development and operations. Teams can connect repositories, manage permissions, inspect code changes, and review builds, regression tests, and deployment checks before merging.
