Open source license means it's both affordable and part of a community

Unlike proprietary solutions, DistrictBuilder is open source so you don't have to pay a license fee. If your team has the expertise, you can download the source code and build your own redistricting application. Or our dedicated DistrictBuilder implementation team can work hand-in-hand with you to create the perfect application for your needs. And if we built a new feature for your application, it is immediately contributed back to the community of users. The more you add, the more we give back.
