Software licenses

Last updated 15 October 2026

The short version

Every Fells Code software project is open source under the Apache License, Version 2.0. There is no separate end-user license and no enterprise edition. The license file in each repository is what governs your use.

This page replaces the end-user license agreement Fells Code published before its software was open source. You do not need to accept anything here to use the software: the Apache License, Version 2.0 already lets you use, copy, modify and distribute it, including commercially, on its terms.

Older releases

Some projects were released under other licenses before they moved to Apache-2.0. Seamless Glance v1.2.0 and earlier, for example, were released under GPL-3.0-only. An older release stays under the license it shipped with, which you can find in that release's source.

Third-party code

Each project depends on third-party open source packages, which are covered by their own licenses as listed in each project's dependency manifest.
