GridRoster
Free rotating shift schedule generator — no signup
Most scheduling tools want your email before you see anything. GridRoster doesn't: open the page, pick a pattern, get a full-year roster. Built for 12-hour shift teams (plants, hospitals, dispatch) running DuPont or 2-2-3/Panama rotations with 4 crews. Print-ready monthly calendars, one month per page, crew colors preserved. Free, no signup, nothing to install.
Hi Product Hunt! I built GridRoster after watching a plant manager friend rebuild his team's rotation in Excel every quarter — merging cells, fixing colors, re-printing. The patterns (DuPont, 2-2-3) are fixed math, yet every existing tool hides them behind a signup wall and a sales call.
So I made the anti-SaaS version: no account, no trial, no install. You open the page, pick a pattern and start date, and get a full-year 4-crew calendar that prints beautifully — one month per page, in color.
It's a single-purpose tool and proud of it. I'd love feedback from anyone running 12-hour shifts: what pattern should I add next?
