Timefold

Timefold is optimization infrastructure, not a chatbot: it solves the brutally hard scheduling and routing problems — field service routes, employee shift planning, logistics — that are NP-hard and defeat naive approaches. Developers integrate production-ready solvers via a stateless REST API, with real-time rescheduling, support for 100k+ shifts, explainability insights that show why the solver made a choice, and handling for complex labor laws and skills constraints. There's an open-source solver option for self-hosting. The team comes from the OptaPlanner lineage, which is about as strong a pedigree as this niche has. The honest caveats: this is a developer product — you need engineering resources to model your constraints and integrate the API — and pricing is enterprise-oriented. For companies burning money on bad schedules and routes, the ROI case is usually straightforward.
