Frequently Asked Questions

Can Supabase replace Firebase for B2B SaaS?

Yes. Supabase offers a more flexible Postgres backend, real-time APIs, and better row-level security for multi-tenant architectures, making it a superior choice for complex B2B use cases.

How do I track conversion funnels in my devtool stack?

Use PostHog to instrument key behaviors like feature usage, share attempts, and PDF generation. It integrates easily with Supabase and Clerk to tie actions to user identities.

Which tool helps prevent CLI and API schema drift?

While none of these tools natively prevent schema drift, PostHog’s event validation and type enforcement plugins can catch mismatches early when combined with proper CI/CD checks.
