Key differences
ScaleMule is built for multi-tenant applications from the ground up. Every query is automatically scoped to the current tenant, and the event mesh supports pub/sub patterns across services. Supabase offers a powerful Postgres-based platform with Row-Level Security for tenant isolation, but the multi-tenancy setup is manual and per-table.
Supabase is open source with a generous free tier, making it a strong choice for early prototyping. ScaleMule is application-based with pricing that starts after approval, designed for teams that need production-grade multi-tenant infrastructure from day one.
