What platforms does Clerk support?
Clerk supports the web, iOS, Android and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.
Can Clerk be self-hosted?
We have only confirmed a cloud / SaaS deployment for Clerk, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.
What does Clerk integrate with?
We have confirmed 5 integrations for Clerk, including Google OAuth, GitHub OAuth, Google Workspace, Convex and MCP. This is what we could verify from public sources, so the vendor may support others we have not indexed.
What security certifications does Clerk have?
We have independently confirmed SOC 2, HIPAA and GDPR for Clerk. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Clerk 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 Clerk, not the verdict.
