The case on Firebase

Keep paying or use managed alternatives like Supabase, because Firebase is an aggregate ecosystem of dozens of complex distributed systems.

Hardest parts

Building a bidirectional real-time synchronization engine with offline conflict resolution and queue merging
Writing a secure, high-performance declarative rule parser and evaluator for database access control
Maintaining stable, type-safe client SDKs across iOS, Android, Web, Flutter, Unity, and C++

The case on Supabase

Build a simple local single-tenant Postgres wrapper or use the real platform, because orchestrating multi-tenant database clusters, WAL change data capture, and RLS gateways is a full engineering platform team's job.

Hardest parts

Multi-tenant Postgres container isolation, health tracking, and automated backups/PITR
Distributed Elixir/Phoenix WebSocket cluster managing Write-Ahead Log (WAL) change data capture
Translating user JWT contexts securely into native PostgreSQL session variables on every request
