The platform also provides a REST API, webhooks, JWT authentication, organization-scoped data isolation, and custom qualifying events and reward rules. Cloud and Open Source plans are each free and include unlimited programs and participants; Cloud includes email support, while Open Source includes community support. The project is in alpha and may have bugs or breaking changes. Self-hosting has specified infrastructure requirements, including PostgreSQL, Redis, and Node.js.
