Anthropic Builds Scion Version Control as Git Hits Its Limits
Anthropic has developed Scion, a version control system meant to replace Git, and has already moved its internal monorepo onto it. The company says AI coding made merge volume the bottleneck: its monorepo ran more than 30,000 merges a day as of September 2026, with roughly 25 million checkouts daily and more than 600 PB of Git traffic. Scion shifts computation to the server.
