FAQ
- How does Auth0 compare to Scalekit on pricing?
- Auth0 prices on tiered-mau; Scalekit prices on tiered-mau. See the pricing comparison table on this page for our editorial estimates at 10k / 100k / 500k / 1M MAU using the standard methodology assumptions.
- Should I switch from Auth0 to Scalekit?
- Switching is a 60–90 day exercise in either direction once SDK rewrites and hooks/Actions migration are accounted for. If your team is hitting cost or feature ceilings on Auth0, evaluate Scalekit on the specific axes flagged in the "When Scalekit wins" list. If you're operating well within Auth0, the switching cost rarely pays back.
- Do Auth0 and Scalekit both support passkeys?
- Both Auth0 and Scalekit support WebAuthn passkeys natively per public documentation. Adoption rates depend on orchestration quality (device-aware prompting, conditional UI), not raw protocol support, see the passwordless guide for the orchestration question.
