Could you build this?
No Building a production Backend-as-a-Service alternative to Supabase/Firebase requires massive distributed systems engineering across database hosting, real-time replication, auth, and multi-tenant security.
What it would actually take: A true BaaS stack combines PostgreSQL orchestration, real-time pub/sub replication engines (like Elixir/Phoenix or Go websockets tailing WAL logs), row-level security policy compilers, serverless function runtimes, and auto-scaling multi-tenant storage. The hard part is ensuring multi-tenant isolation, real-time change data capture (CDC) at scale, zero-trust security rule engines, and reliable high-availability database cluster management. It demands a dedicated team of distributed systems, database internals, and infrastructure engineers.
