wedge thesis

the door is vertical focus: Supabase is a horizontal BaaS for everyone, which means no niche owns it — a narrower clone targeting one stack (mobile-only, edge-only, AI-native) can win that segment before Supabase's breadth becomes relevant.

color around the thesis

“Supabase is open source, self-hostable, and already beloved — you're not out-featuring them. The wedge is picking one lane they're too broad to defend: AI-native apps, mobile-first, or a specific compliance vertical.”

The core stack (Postgres + PostgREST + GoTrue + Realtime) is all open source and composable. A solo dev can assemble a credible hosted version of it. The hard part isn't the tech — it's that Supabase has 100K+ GitHub stars and a developer community that functions as a distribution moat. You're not beating them on features; you're carving off a niche they're too general to serve well.

easy

medium

hard

nightmare

easy

Postgres provisioning per project

Spin up a Postgres instance per tenant. pg_createdb + role isolation. Scripted in an afternoon.

easy

PostgREST auto-API layer

Drop PostgREST in front of Postgres. Instant REST API from schema. Zero custom code.

medium

Dashboard UI (table editor, SQL runner, auth manager)

This is the most visible surface. Weeks of React work, but no novel algorithms — just CRUD over your own API.

medium

Row Level Security policy editor

Parsing and surfacing RLS policies in a UI is fiddly. Users expect it to feel safe and obvious. It rarely does on first pass.

hard

Realtime subscriptions (Postgres logical replication → websockets)

Supabase uses a custom Elixir server (Realtime). Replicating this means managing WAL slots, connection pooling, and broadcast fan-out under load. Non-trivial.

nightmare

Multi-tenant ops at scale (provisioning, isolation, backups, upgrades)

The product is easy. The platform is the nightmare. Per-project Postgres isolation, automated backups, version upgrades, connection poolers, and billing metering — this is what Supabase's infra team actually does all day.
