Logto
The fastest route from nothing to working sign-in.
87
sovereigntyLogto is the pragmatic middle: pre-built sign-in UI, SDKs for the common frameworks, social logins, MFA and multi-tenancy, deployable with Docker in well under an hour. It is aimed squarely at product teams who need authentication to work this week rather than an identity platform to administer for a decade. MPL-2.0 with a paid cloud tier. It is the smallest and youngest option here, which is the honest caveat, but for a startup replacing Auth0 it removes the most friction.

What it does well
- +Fastest of these from zero to a working sign-in flow
- +Sign-in UI included — no screens to build
- +Good SDKs for React, Next.js, Vue and the mobile frameworks
- +MPL-2.0 is permissive and easy to reason about
Where it falls short
- −Youngest and smallest project on this page
- −Not built for employee SSO across hundreds of apps
- −Fewer enterprise features than Keycloak
- −Multi-tenancy is newer and less proven than ZITADEL's
