Where Postman shines
- Unified platform replaces 4–6 separate tools (client, design, test, monitor, docs, mock servers).
- Free tier is genuinely usable for individuals: unlimited local collections, 50 AI credits/month, all protocols.
- Workspaces (Internal, Partner, Multi-Partner, Public) solve API collaboration at every scale.
- Postman CLI runs collections in CI/CD without a GUI, critical for GitHub Actions, GitLab, Jenkins, CircleCI.
- The free plan caps collaboration at 3 users and 3 collections shared in a workspace, which is too limited for team use.
- Postman's desktop app is resource-heavy. Running Postman alongside multiple browser tabs can slow down older machines.
Where Supabase shines
- Real Postgres under the hood, so you keep SQL and relations instead of a NoSQL lock-in
- Generous free tier with a database, auth, and daily backups at no cost
- Realtime and auth built in, so a backend for a small app ships without extra services
- Compute resource instances on free and lower plans can pause after 7 days of inactivity, introducing cold-start delays when reactivated.
- Row Level Security (RLS) policies require meticulous SQL query optimization to prevent severe query latency bottlenecks under high concurrent read volumes.
