FAQ
What is the best authentication solution for SaaS?
Clerk offers the fastest setup with beautiful pre-built UI components, MFA, social OAuth, and B2B multi-tenancy, ideal for modern web apps. WorkOS specializes in enterprise SSO and SCIM for B2B products selling to larger companies. Auth0 provides the most comprehensive identity platform for complex requirements. Supabase Auth is an excellent free, open-source option bundled with its database platform.
How do I choose between managed auth and self-hosted?
Managed solutions like Clerk and WorkOS save weeks of development time and handle security updates automatically, but create vendor dependency and per-MAU costs that scale. Self-hosted options like Supabase Auth and Keycloak give complete data control and eliminate per-user costs, but require DevOps expertise and ongoing maintenance. Most startups should start managed and consider self-hosting as they scale.
What infrastructure tools do GTM engineers need?
GTM engineers typically need: authentication (Clerk or Supabase Auth), a database (PlanetScale or Supabase), edge hosting or serverless compute, a feature flag system (PostHog or LaunchDarkly), error tracking, and monitoring. Many teams consolidate with platforms like Supabase that bundle database, auth, storage, and edge functions together.
