What licensing terms apply to TeamCity, YouTrack, and Upsource?

TeamCity, YouTrack Standalone, Upsource, and Hub remain under the perpetual licensing model. These licenses are perpetual for the versions they cover.

This means that you can run a covered version with existing licenses for unlimited time, and the licenses will stay valid for this version.

Each license has a maintenance period (generally 1 year). The license key is valid with any version released within the maintenance period. Licenses valid for the major/minor release (changes in the first two release numbers) are also considered valid for the corresponding bug-fix updates (changes in the third release number).

YouTrack inCloud, a hosted solution by JetBrains, has been and will continue to offer subscription scheme for the service.
