What is Auth0?

Auth0 is a developer-focused customer identity platform (CIAM) now owned by Okta but sold as a separate product. It provides drop-in login, social sign-in, passwordless authentication, and multi-factor auth for applications, with SDKs for nearly every major framework. Auth0 is especially popular with SaaS startups because of its generous free tier and developer experience: you can go from zero to a working login flow in minutes.

Best for: SaaS teams that need customer login with a great developer experience

Pros

  • Excellent developer experience and documentation
  • Generous free tier covers most early-stage apps
  • Extensive SDKs for every major framework
  • Actions and Rules allow flexible custom logic

Things to check

  • Pricing gets expensive fast past the free tier
  • Okta acquisition raised long-term pricing concerns
  • B2B pricing tier jumps sharply for simple orgs support
  • Admin UI can feel dense for non-developer users
