Tested: Neon Free plan, API v2 + serverless HTTP driver, Postgres 18.6 · 2026-10-16
Free tier: Yes: 100 CU-hours/project/mo, 1 GB storage/project (20 GB account total), 5 GB transfer/project, 10 branches/project
3/3 runs: one API call created a Postgres branch with compute that answered queries ~2s later; created a todos table, inserted, updated and read rows, then deleted the branch.
Pros- A new Postgres branch was queryable about 2s after one API call
- Branching makes throwaway test databases trivial
- HTTPS serverless driver works where TCP 5432 is blocked
Cons- The projects API demanded org_id even for a single-org account
- Our test covered the database only, not auth
Best if: Indie devs who want serverless Postgres with instant branches for previews, tests and AI agents.

Tested: Supabase Cloud, Free plan (ap-southeast-2); self-hosted Docker edition also tested: 8.6 · 2026-10-16
Free tier: Yes: 2 projects, 500 MB DB, 50K MAU; pauses after 1 week inactive
Cloud: project provisioned in ~9s, table + REST write/read + email signup/login/wrong-password rejected passed 3/3 runs (~12s task).
Pros- Cloud project provisioned in about 9 seconds
- Database, REST API and email auth all passed 3 of 3 runs
- Generous free tier: 2 projects, 500 MB database, 50K MAU
Cons- Free projects pause after 1 week of inactivity
- Self-hosted Docker had an unhealthy edge-functions container on our box (scored 8.6)
Best if: Indie developers who want Postgres, auth and an instant REST API in one backend.

Tested: Open-source local backend (anonymous local deployment via Convex CLI), not Convex Cloud · 2026-10-16
Free tier: Yes: 1M function calls, 0.5 GB DB
3/3 runs: push functions, insert and query rows, arg validation, all OK in about 7-8s each (warm).
Pros- Push functions, insert, query and validation passed 3 of 3 runs
- Each run took about 7-8 seconds
- Free tier includes 1M function calls
Cons- Self-hosted Docker images returned 'denied' for anonymous pulls in our test
Best if: TypeScript developers who want a reactive backend with functions and a database in one.
