An autonomous AI software engineer that resolves GitHub issues and creates review-ready pull requests with test evidence and recordings.

Reason is an autonomous AI software engineer designed for teams and companies. It connects to GitHub, accepts assigned issues, and autonomously works through reproducing bugs, editing code, running tests, and creating pull requests with complete evidence including test results, recordings, and logs.
The platform operates on the principle that code and live evidence should verify every change. Each session runs on its own dedicated computer environment that users can watch from any browser. Reason is built to handle the mechanical middle of coding—reproduce, edit, verify, review, remember—while humans retain control over direction, judgment calls, and design decisions.
The product emphasizes cost efficiency and has been shown to outperform competitor models. It offers both cloud-based and local runtime options, with support for GitHub integration, mobile access, and enterprise security certifications.
