About Reason 1.0

Developed by Reason Machines, Reason 1.0 is an autonomous cloud coding agent engineered to resolve real-world software engineering issues. Reason connects directly to GitHub repositories, spins up isolated sandbox computers, runs test fixtures, diagnoses root causes, and produces complete pull requests accompanied by screencasts, terminal logs, and execution evidence. With first-class MCP support and top-tier benchmark results on DeepSWE v1.1, Reason solves issues with up to 39% lower median time than competing baselines.

  • Every pull request includes screen recordings and terminal logs proving changes work
  • Top-tier DeepSWE benchmark performance with 39% faster median solving time
  • Official publisher-owned MCP plugins for Claude Code and OpenAI Codex
  • Full repository sandbox isolation with reproducible test verification
  • Commercial service requiring account configuration and usage credits
  • Complex multi-repo enterprise setups require configuring workspace permissions
