Redesigning source control at Anthropic
The gist
Anthropic built an in-house version control system, Scion, and migrated its monorepo off git.
The move shows AI-written code is outpacing developer tools built for human scale.
How it unfolded
- May 2026Anthropic averaged around 2,500 code changes merged per day.
- Jun 2026GitLab announced next-gen SCM at GitLab Transcend, joined on stage by Nick G. from Anthropic's source control team.
- Aug 2026GitLab shared more of its architecture and early performance results for next-gen SCM.
