What platforms does Scale AI support?
We have confirmed browser-based access to Scale AI. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.

Can Scale AI be self-hosted?
We have only confirmed a cloud / SaaS deployment for Scale AI, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.

What security certifications does Scale AI have?
We have independently confirmed SOC 2, ISO 27001 and GDPR for Scale AI. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Scale AI not holding them. Always confirm compliance directly before you rely on it.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Scale AI, not the verdict.
