Going forward, we will be relicensing our core open source projects (Grafana, Grafana Loki, and Grafana Tempo) from the Apache License 2.0 to the Affero General Public License (AGPL) v3. Plugins, agents, and certain libraries will remain Apache-licensed. You can find information in GitHub about what is being relicensed for Grafana, Loki, and Tempo.
AGPLv3 is an OSI-approved license that meets all criteria for Free and Open Source Software.
Ensuring we maintain these freedoms for our community is a big priority for us. While AGPL doesn’t “protect” us to the same degree as other licenses (such as the SSPL), we feel that it strikes the right balance. Being open source will always be at the core of who we are, and we believe that adopting AGPLv3 allows our community and users to by and large have the same freedoms that they have enjoyed since our inception.
