SuperTokens Review

Depends

Should I use SuperTokens?

Open Source User Authentication. Build fast, maintain control, with reasonable pricing. - supertokens.com

· 1 month ago

Buy it if you have engineers and want self-hosted control with no per-user fees. Skip it if you lack technical staff or want a fully managed vendor to hold accountable.

Confidence

Medium. Based on 20+ public sources; exact paid pricing and named customers are absent from the evidence.

Best for

  • Anyone unwilling to self-manage a security component

Migration tooling exists, but switching auth providers still carries session-migration work
