Why people consider alternatives to Auth0

Auth0 is an identity platform that makes authentication easy for developers. Add login, signup, and MFA with just a few lines of code. Support for social logins, enterprise SSO, and passwordless.

Here are the real cost and limitation gotchas that push teams to look elsewhere:

Overage pricing at $0.07/MAU applies per user beyond the base limit.
B2B Essentials limits you to 3 enterprise SSO connections and Professional to 5.
SMS-based MFA is not included in the base price.
The free plan lacks separate development and production environments. Running auth against production data during development is a real compliance and security risk that most teams eventually pay to fix.

The 9 alternatives below cover the same core job (identity & access) with different trade-offs.
