About Reason
Reason is a coding agent from Reason Machines that works on engineering tasks and produces pull requests for review. The current homepage presents Mac, mobile, web and Slack interfaces, and Reason Network connects agents into a shared workflow. The specific mobile operating systems and a current Linux distribution are not established by the public page.
Users can delegate coding tasks, inspect agent work and review the resulting changes. The October 10, 2026 announcement identifies Reason Agent 1.1 and describes parallel tool execution and a small core tool set. Its benchmark comparisons are vendor-reported, model- and benchmark-specific results, rather than a general performance guarantee.
The site links to a sign-in flow and a trust center advertising zero data retention and SOC 2. No public subscription price, free allowance or trial terms were visible on the homepage or sign-in page during review.
