Beyond the happy path
Vercel and Supabase make it possible to move from idea to application faster than ever. Real users introduce a different class of problems: security, data integrity, migrations, performance, observability, reliability and cost.
Production architecture is the simplest design that can reliably support what comes next — not the most impressive demo.
Vercel: deployment, caching and compute
Use ISR and tag-based revalidation intentionally. Separate static marketing from authenticated app surfaces. Monitor function duration, cache hit rates and edge vs Node boundaries.
Fluid compute and serverless are powerful — but only when workload patterns match the model.
Supabase: PostgreSQL with RLS as production policy
Treat RLS as your authorization layer, not an afterthought. Version migrations. Test policies per role. Plan connection pooling and read patterns before scale events.
