What does the FusionAuth license apply to?
The FusionAuth license applies to the FusionAuth bundle fusionauth-app which is used by all of our installation methods (ZIPs, DEBs, RPMs, Docker, K8s, etc).
The fusionauth-search bundle is vanilla ElasticSearch, and is covered by the version appropriate ElasticSearch license.
All other code such as client libraries and example applications are covered under their own licenses, which are usually Apache 2.0. Refer to each project for the correct license.
