Choose Auth0 if
Companies with enterprise SSO requirements or large consumer user bases.
- Generous free tier (25k MAU)
- Enterprise SSO and compliance depth
- Reliable at huge scale
Look elsewhere if: Early-stage React apps wanting prebuilt UI (Clerk) or teams wanting self-hosted ownership (Better Auth, Keycloak).
Choose Neon if
Developers who want elastic Postgres with branching and are comfortable assembling the rest of the stack.
- Branching changes development workflows
- Pay only for compute you use
- Fast provisioning, great for AI agents and previews
Look elsewhere if: Teams wanting an all-in-one backend (Supabase) or steady high-throughput workloads where reserved instances are cheaper.
