RetroFill

RetroFill fills your GitHub contribution graph with real git commits, not a log file. Preview any public profile for free with no sign-in, paint days by hand, or let the realism engine generate a human-looking year (weekday bias, busy and quiet months, vacations, work-session timestamps). On execute it creates one new repo you name and pushes backdated commits with real diffs. Gap-only by default; read-only sign-in; writes go through a GitHub App limited to repos you pick; one-click undo deletes the repo. A green graph is not a résumé — anyone can open the repo.
