GridRoster

Hi! I built GridRoster after years of wrestling with spreadsheets for 4-crew rotating shifts. It generates DuPont, Panama, 4-on-4-off and other 12-hour rotations instantly in the browser — no signup, print-ready. I'd love your feedback on which shift patterns to add next.

Offering named rotation patterns such as Panama, DuPont, and Pitman as ready templates is the strongest choice here, because managers usually know the pattern name but struggle to build it fairly in a spreadsheet. The print-ready PDF and shareable link also fit how rosters are actually used. One useful addition would be a fairness check that flags when one crew gets noticeably more weekend or night shifts than the others.

Having the named patterns (Panama, DuPont, Pitman) as ready templates is the right call; most managers know the name but not the grid. Does the shareable link update if I tweak the rotation later, or is it a snapshot? And have you thought about letting people swap a single shift without breaking the pattern?
