Anthropic creates custom code tracking software after outgrowing Git

Anthropic recently replaced the traditional code management system Git with a custom internal tool named Scion. According to an engineering update from the company, their automated AI systems generated software at such a rapid pace that standard developer tools collapsed under the workload. Merged code updates rose from roughly 2,500 per day in May 2026 to over 30,000 per day by September 2026, prompting engineers to design a centralized setup tailored specifically for AI agents.

For everyday consumers, this development shows how artificial intelligence is beginning to stretch the foundational plumbing of the tech industry. Standard software tools were designed around human limits, like typing manually and storing complete file histories locally on a personal computer. As AI agents generate code at massive scale, tech companies will have to rebuild fundamental backend systems to keep internet services running without constant bottlenecks.

What remains unclear is whether Anthropic plans to share Scion publicly or if other software firms will have to invent their own custom tools. Additionally, shifting to an always-online centralized model creates a new point of failure. If an enterprise relies entirely on continuous server connections for every tiny code query, a simple network outage could completely freeze automated development pipelines across an entire organization.
