   Anthropic replaces Git with in-house Scion as Claude-generated code surges

   Anthropic disclosed in an engineering blog post that it has moved its main monorepo off Git and onto an in-house version control system called Scion. Anthropic says merged code changes rose from about 2,500 per day in May 2026 to more than 30,000 per day by September, with main-branch history near 100 GB and CI performing roughly 25 million code checkouts daily; Scion moves operations such as commits, merges and history queries to servers while clients keep only limited caches. Anthropic's internal measurements put Scion's infrastructure CPU and memory use at about one two-hundredth of the Git mirror setup it replaced, with checkouts falling from minutes to seconds and CI saving about 25% of CPU capacity; the system was built by a seven-person team over five months with help from Claude, and Anthropic stresses Scion targets very large repositories and many online agents rather than serving as a general Git replacement.
