Anthropic replaced Git with Scion as code merges rose to 30,000 per day
Anthropic says its monorepo grew from about 2,500 merged changes per day in May to over 30,000 in September, prompting a five-month migration from Git to Scion and new review and source-control systems. The account shows how agent-driven code volume can force a redesign of developer infrastructure.
- What
- - Scion is Anthropic’s in-house version control system, built as the company migrated its monorepo from Git.
- How
- - Anthropic’s daily merges rose from about 2,500 in May 2026 to over 30,000 in September; Git mirrors and repository seeds became harder to operate.
- Why it matters
- - The case shows how AI-driven code production can shift bottlenecks to source control and other developer infrastructure built for human-scale workloads.
