How GitHub builds GitHub with GitHub
summary
GitHub shows how it builds itself using its own stack: Codespaces starts a full dev environment in under a minute instead of cloning a 16 GB repo, GitHub Actions runs matrixed builds and parallel deployments, and CodeQL plus push protection blocks leaked tokens and finds HTTP/OAuth bugs before merge. The org ships ~80,000 deployments a year, hosts ~100M accounts, serves ~4B API requests/day, and records 1.5M commits in the main repo; feature flags, telemetry queries and Copilot (used by ~75% of engineers) close the loop.
