AGPLv3 (copyleft license)
AGPLv3 is an open-source license that keeps software free and open, and requires that hosted versions stay open too.
AGPLv3 is the GNU Affero General Public License, version 3. It is a copyleft license, which means anyone can use and modify the software, but improvements and hosted versions have to stay open under the same license. It is designed to keep open software open, even when it is offered as a service.
For a practice, the license is a promise. It means the software cannot quietly become closed and locked down later. The openness is legally protected.
OpenVPM is licensed under AGPLv3. That is why we can say the code stays yours to run and inspect, not just today but going forward.
