Show HN: Git-chain – Simplify branch dependency management in Git

https://github.com/hammadfauz/git-chain
1•hammadfauz•1y ago
I built Git-chain because managing dependent branches and open PRs was becoming painful. This tool helps automate and track those relationships easily.

I made some usability improvements: * Made chain storage more robust. * Added a way to clear a chain * Added tab completion for branch names * Changed github workflow to show error instead of warning (more obvious, can be bypassed via github UI)

Hi HN,

I built Git-chain to help with branch management in trunk-based development workflows.

When you want to keep changesets small and reviewable, but still build new work on top of unmerged changes, Git can get messy fast. Git-chain makes it easier to track and manage these dependent branches cleanly.

Would love feedback — especially from teams doing trunk-based development!
