Building Git infrastructure for agent-scale development

Every day on GitHub, millions of developers build the products their customers rely on, contribute to open source, and pursue personal projects. GitHub’s architecture has changed steadily over the years to support that work and the growing demands of the developers and organizations who depend on it.

Agentic software development is driving the next architectural shift. With developers and agents working concurrently in repositories that receive millions of commits a day, these workloads demand a different Git architecture. We’re rebuilding GitHub’s Git infrastructure to support them. This post explores the demands shaping that work and the design principles behind it.

Today’s highest-volume workloads show the scale we’re building for. The gap between a typical repository and the busiest ones is wider than most people expect. Here’s a rough picture of the monthly repository activity distribution on GitHub from August 2026:

Repository activity climbs sharply at the far end of the distribution. …
