Open Source Scheduling Software

Workforce scheduling lives or dies on the rules nobody sees in the grid - overtime thresholds, mandatory rest gaps, certifications, availability windows, and union clauses that quietly make one roster legal and another a liability. The open source rostering systems here let you encode those shift rules, swap requests, and coverage constraints yourself, so the logic that decides who works when is something you can read and adjust rather than a black box that hands you a schedule and a compliance risk.
