Data labelling vendors, ranked by what they publish

Data annotation and labelling platforms, ranked by what they publish about how they handle your data.

11 vendors measured on their own sites, last on 2026-09-02. 11 ranked. A vendor we could not measure often enough gets no rank at all, rather than a bad one.

Public transparency score, not a product or security rating. Transparency means: published on the vendor's own site, readable without a login, found by us at the addresses we checked.

How this market does on each criterion, with its own share and how it compares with the rest.

Every result links its source on the vendor page. A dash means we could not measure it, not that it is missing. See how we score.
