Open Source
Synergy stands on the work of countless upstream open source projects, from the libraries and toolchains we build with to the platform code that lets it run on every operating system. Thank you to everyone who has contributed to any of them, whether in code, documentation, testing, or support, and to everyone who has worked on the open source Core behind this release. We could not build Synergy without you, and we are grateful to be part of the community that makes this software possible.
