How is it different from github.dev

PlainHub is a notepad with GitHub as its backend — open, edit, save. Different tools for different use cases.

Document History & Restore

PlainHub creates a Git commit with every save, so without any extra effort you get:

  • Automatic change history — All file changes are recorded in Git. Always track who changed what and when
  • Restore to any point — Browse and restore past states from Git history
  • Diff view — Visually compare before and after changes
  • No branches needed — Non-engineers can just save to the main branch for version control
