Synergy Enterprise: Supported, stable and reliable

Synergy Enterprise is our professional version based on Synergy (this project). The code base for Synergy Enterprise is forked from the community version of Synergy and is developed by us. The difference is that we carefully improve and specialize our enterprise version based on enterprise customer feedback. At every release we thoroughly test our enterprise version to make sure that no bugs are reintroduced (regression testing), giving you higher confidence when upgrading.
