## What it is
git-filter-repo is a fast, versatile tool for rewriting Git repository history, recommended by the Git project as a replacement for git filter-branch. It works as a single-file Python CLI script and also provides a library for building custom history-rewriting tools.

## Use cases
- remove large files or secrets from git history
- rewrite commit history of a git repository
- replace git filter-branch with a faster alternative
- clean sensitive data out of a repo before open-sourcing
- rename or move files across all commits
- build custom git history rewriting scripts

## When to choose
- you need to rewrite large repository history quickly
- git filter-branch is too slow or limited
- you want the tool officially recommended by the Git project
- you need programmatic history rewriting via a Python library

## When to avoid
- you only need to undo recent commits (use git reset or rebase)
- you want an interactive rebase of a few commits
- you cannot rewrite history because the repo is shared without coordination
