Welcome to utis.cc

This site is meant for hosting UTIs (Uniform Type Identifiers) that are not specific to one application or developer but shared among many apps, and therefore considered “open source”.

The domain utis.cc has been reserved for this purpose (currently paid until July 2026).

If you’re a developer and like to register a shared UTI, please contact us via the Issues tracker.
