Commercial License

This software is dual-licensed:

  1. GNU AGPL-3.0 — for open-source use, self-hosting, and community contributions
  2. Commercial License — for use cases that require avoiding AGPL obligations

When you need a commercial license

You need a commercial license if your use case involves any of the following and you do not want to release your modifications under AGPL-3.0:

  • Self-hosting a modified version at a venue or organization (e.g., karting tracks, sim racing centers)
  • Embedding or bundling this software into hardware products (e.g., data loggers, OBD-II devices, telemetry hardware)
  • Offering a modified version as a network service (the AGPL-3.0 §13 network-use clause requires sharing all modifications if you don't have a commercial license)
  • Distributing modified versions without releasing source code

When you do NOT need a commercial license

  • Personal, non-commercial use (e.g., analyzing your own sim racing telemetry)
  • Studying, modifying, or contributing to the open-source project
  • Self-hosting an unmodified version for personal use
  • Any use where you are comfortable releasing modifications under AGPL-3.0
