Anthropic replaces git with in-house version control for its monorepo
Overview
Anthropic says it built a new version control system and fully migrated its monorepo off git in five months, because daily merges rose from about 2,500 code changes in May to more than 30,000 in September.
The company says developer infrastructure built for human-scale work became the bottleneck. The account comes from Anthropic's engineering blog post, which Anthropic and Ado Kukic shared on X; no independent verification of the migration or its results has been reported.
Gergely Orosz says the new system is closed source and that Anthropic has no plans to release it. He notes that Bun and MCP are the only open-source projects from Anthropic.
