Choose Insomnia if
Developers who want a fast, local-first, open-source API client with Git-based collaboration.
- Open-source core under the Apache 2.0 license

Look elsewhere if: Teams that need a full API platform with published docs and broad workspace collaboration (Postman, Apidog, Stoplight).
Choose Supabase if
Developers and startups who want a Postgres-based backend with batteries included and an exit path.
- Real Postgres, no proprietary data model
- Generous free tier; Pro is affordable
- Open source and self-hostable
Look elsewhere if: Teams needing multi-region writes or non-relational models by default.
