Schema Structured schema with migrations Flexible schema (schemaless)
Joins & Relations Full SQL joins, foreign keys Embedding or application-level joins
Auth Built-in complete auth system Requires Realm Auth or third-party
Realtime WebSocket subscriptions Change streams (more complex setup)
No-Code Integration Native WeWeb connector REST Data API (manual config)
Row-Level Security PostgreSQL RLS (database-enforced) App-level rules
Free Tier 500MB, 2 projects 512MB shared (M0 cluster)

Notre verdict

Supabase Better for most startups
MongoDB Better for document-heavy data

For most startup apps — especially those with relational data, user accounts, and complex queries — Supabase wins. PostgreSQL's SQL querying, Supabase's built-in auth, and native no-code connectors make it the most complete solution.

MongoDB Atlas makes sense when: your data is genuinely document-shaped (no predictable schema), you're storing large nested JSON objects, or you need MongoDB's specific aggregation pipeline features.

For no-code apps, Supabase is the clear choice. For pure API/backend projects with genuinely document-shaped data, MongoDB is worth evaluating.
