What is Shift & Roster Studio?

Shift & Roster Studio is more than a printable grid. It considers availability, preferred days off, headcount, roles, qualifications, consecutive days, and rest gaps to generate, validate, and repair schedules.\n\nNo accounts and no uploads — names and shifts never leave your device unless you choose to share a URL fragment.

Start simple

Paste staff names, set days and headcount, then generate. Try the sample cafe (8 staff, 1 week) to learn the flow in seconds.

Explain problems, preview fixes

Understaffing and preference conflicts are labeled Critical/Warning/Info with causes and options. Auto-fix shows before/after metrics before you apply.

Fairness and estimated labor cost

Compare hours, weekends, nights, streaks, and preference hits. Labor cost is an estimate from your rates — not a legal payroll calculator.

Export and share privately

Autosave to localStorage, export CSV/JSON/PNG/print, and optional URL-fragment sharing with an explicit privacy warning.

FAQ

Are staff names uploaded?

No. Scheduling runs entirely in your browser.

Is this compliant payroll software?

No. It is a planning tool with user-defined rules and estimated costs only.

Does it work on phones?

Yes. Editing uses a two-tap flow instead of requiring drag-and-drop.

Is there a sample?

Yes — a cafe with 8 staff for one week.
