Supabase Development Service

Supabase is the most productive backend for early-stage SaaS in 2026. Auth, Postgres, storage, realtime, and edge functions in one platform. The Postgres database is real Postgres — you can run a Supabase query in psql, inspect the schema, and migrate it like any other Postgres. But that openness is also the danger: most Supabase apps in production have Row Level Security misconfigured, which means any authenticated user can read other users' data.

RLS is non-negotiable when using the Supabase client from the browser. The `anon` and `authenticated` keys are public; they end up in your bundle. Without policies, your tables are wide open. Junior developers either disable RLS entirely "until we figure it out" (which becomes permanent) or write policies that look right but bypass via foreign-key relationships. We have audited Supabase apps where flipping a single UUID in the URL leaked every customer's billing history.

Edge functions are TypeScript on Deno Deploy. They are great for webhook handlers, third-party integrations, and anything that needs a service role key. The runtime quirks (no Node-specific APIs, limited dependency tree) trip up developers who expect Vercel-style serverless. We design edge functions with idempotency, structured logging, and proper error handling from day one.

Realtime is powerful but easy to abuse. Subscribing every browser to every table change is fine at 10 users and catastrophic at 10,000. We design realtime channels around the bounded data a single user needs — their own messages, their team's notifications — not the global firehose.
