Licensing

KetQat's own code

The ketqat-sdk repository (contracts, schemas, reproducibility hashing, the local runner, and the typed client) is open source under the Apache License 2.0. Fork it, embed it, build on it.

The KetQat web application itself is not open source. This is a deliberate choice, not a contradiction of KetQat's vendor-neutral mission: neutrality comes from the public contracts, schemas, and hashing rules being open and independently implementable -- not from every line of the hosted registry's server code being public. Hugging Face's own hub follows the same split.

Content you submit

Artifact descriptions, benchmark suite definitions, and benchmark run results you submit to the public registry are licensed under CC BY 4.0: anyone may reuse, redistribute, and build on them, as long as they credit you (the citation block on every artifact and run page exists for exactly this). You retain full ownership of what you submit; this license grants reuse rights, it doesn't transfer ownership.

Content marked PRIVATE is visible only to you and administrators, and is not covered by CC BY 4.0 while private -- it becomes CC BY 4.0 licensed if and when you make it public.

By submitting content, you confirm you have the right to share it under these terms -- e.g. you wrote it, or its own license permits redistribution with attribution.
