I built this in 2018 as a school project to bulk delete GitHub repos. It got 25k views on Medium and ~10k users organically, then I basically ignored it for years.

Recently I dug into GitHub's community discussion board and some low hanging fruit for feature additions — archive, visibility changes, collaborator cleanup.

GitHub's answer was always "use the API." So I built the UI.

  RepoSweeper now does:
  - Bulk archive / unarchive
  - Bulk visibility (public ↔ private)
  - Bulk collaborator add/remove
  - Staleness scoring so you know what to act on first
  - Handles 100+ repos with persistent selection across pages

It's free forever. Just GitHub auth, no install.

Also wrote about how it evolved today if curious: https://medium.com/@osoh_app/github-has-no-bulk-anything-so-...

Let me know if you have any feedback. I'm also working on RepoRecap which is more of a productivity summary tool for individual devs.
