Which Should You Choose?

Choose Auth0 if:

  • •User authentication - login, MFA, SSO, and user management - is the requirement
  • •You need a hosted identity service that manages tokens and sessions
  • •Enterprise compliance and multi-tenant auth are driving the decision

Choose tRPC if:

  • •You want end-to-end type-safe API calls between your TypeScript frontend and backend
  • •Eliminating REST or GraphQL boilerplate while maintaining full type safety is the goal
  • •You're building a full-stack TypeScript app (Next.js, SvelteKit) and want tRPC's DX

Auth0 is a managed identity service; tRPC is an open-source TypeScript framework for building type-safe APIs. tRPC is free (MIT license). Auth0 is free to 7,500 MAUs. These tools often work together - tRPC procedures can use Auth0 tokens for authorization middleware. No competition.
