## Frequently Asked Questions

### Should I build internal auth or use a library?

Never build raw authentication from scratch. Use an open-source library like Better Auth or Supabase Auth. It prevents security vulnerabilities, session handling bugs, and credential leak risks.

### What analytics tool is best for early-stage B2B SaaS?

PostHog is the gold standard for early products because it combines event capture with session recordings. Watching real users get stuck on your onboarding page reveals conversion leaks faster than raw numbers.
