Timefold

Enterprise scheduling optimization APIs and a proven constraint solver

Domain-specific optimization APIs

Ready-made REST APIs for field service routing, employee shift scheduling, pickup and delivery routing, and task scheduling, each tuned to the constraints those problems actually involve.

Custom API from a conversation

Describe your scheduling problem in natural language and Timefold generates an API that solves it, shortening the path from idea to a working optimizer.

Stateless REST over JSON

Send JSON in and get JSON out through a technology-agnostic, stateless API, so you can integrate without rewriting your architecture or adopting a new platform.

Explainability and what-if analysis

Inspect constraint scores, compare scenarios, and run simulations so planners and stakeholders can understand and trust the decisions the solver makes.
