ax is dual-licensed:
-
AGPL-3.0 (see
LICENSE) - free and open source. If you build on ax and run it as a network service or ship it inside your product, the AGPL requires you to release the complete corresponding source of your work under the AGPL too. -
Commercial License (this document) - for teams that want to use, embed, host, or resell ax inside a closed-source or proprietary product or service, without the AGPL's source-disclosure obligations.
You need a commercial license if any of these apply and you do not want to open-source your surrounding code under the AGPL:
- You offer ax (modified or not) to third parties as a hosted/SaaS service.
- You bundle or embed ax into a proprietary product you distribute or sell.
- You build a commercial product whose value materially depends on ax and you cannot meet the AGPL's network-copyleft terms.
You do not need a commercial license to:
- Use ax internally on your own machines.
- Self-host, study, modify, and share ax under the AGPL-3.0.
- Contribute back to the project.
A commercial license grants you the right to use ax under proprietary terms (no AGPL source-disclosure requirement), with terms negotiated per the size and nature of your use. Pricing is typically a flat annual fee or a revenue-based arrangement.
