Timefold Solver Community Edition is an open source project, and you are more than welcome to contribute as well! For more, see Contributing.

Should your business need to scale to truly massive data sets or require enterprise-grade support, check out Timefold Solver Enterprise Edition.

How to use Timefold Solver

To see Timefold Solver in action, check out the quickstarts.

With Maven or Gradle, just add the ai.timefold.solver : timefold-solver-core : 1.0.0 dependency to get started.

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 1.0.0) to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.
