killbill.iorepositorydocspricing
Kill Bill is an open-source subscription billing and payments platform written in Java. It runs as a server with the Kaui administrative console for operators, and it exposes a REST API for applications. The getting-started guide covers an install with the official Docker images and Docker Compose, a manual install on Apache Tomcat with MySQL, and a one-click installer for AWS.
The core team uses MySQL and also runs regression tests against MariaDB and PostgreSQL.
Worth knowing
Aviate is the enterprise edition, sold under a commercial license. The pricing page says to choose Aviate for enterprise features and support.
The manual Tomcat install needs JDK 11.
