About git-sizer

git-sizer computes a range of size metrics for a Git repository and highlights the ones large enough to cause problems. It is useful before migrating a repository to a hosting service, when a clone has become slow, or when deciding whether history needs cleaning up.

It is a small Go program run from the terminal inside a repository. GitHub maintains it, and the repository was updated in September 2026.

Strengths

  • Flags size metrics that are likely to cause trouble
  • Single command, no setup inside the repository
  • Maintained by GitHub with recent activity

Limitations

  • Reports problems but does not fix them
  • Command-line only, no graphical output
