This repository tracks notable SaaS platforms and open-source projects for Shift Scheduling. These tools help managers create and publish schedules, handle shift swaps, track time and attendance, manage availability, communicate with teams, and control labor costs across retail, hospitality, healthcare, and other shift-based industries.
Examples include Deputy, When I Work, Sling, Planday, Humanity, ZoomShift, Homebase, Connecteam, Skello, and Shyft (the category leaders).
Open-source emphasis: This section is heavily expanded with every major active project for self-hosting shift planners, rostering tools, and workforce scheduling systems — ideal for teams that want data ownership, no per-user fees, and customizable scheduling without vendor lock-in.

- This is a community-curated list — not exhaustive and not an endorsement.
- Shift scheduling often intersects with labor law, overtime rules, and payroll. Self-hosted solutions require careful configuration for compliance with local regulations.
- Open-source tools typically lack the polished mobile apps, payroll integrations, and support of commercial platforms; evaluate operational readiness before production deployment.
Made for managers, operations teams, small business owners, and developers building workforce tools.
Let's make shift scheduling more transparent, flexible, and open.
