Postman: pros & cons
- Universal Standard: The most widely accepted and used API tool in the industry.
- Scripting Power: Write automated tests for every API request using JavaScript.
- Documentation: Transform your collections into stylish API docs with one click.
- Mock Servers: Allow frontends to keep working even before the backend is ready.
- Resource Usage: The desktop app can consume quite a bit of RAM during heavy work.
- UI Bloat: For those just wanting to send a simple request, the UI can be overwhelming.
- Cloud Reliance: Some collab features require data to be held on Postman's servers.
Our verdict on Caddy
The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
Our verdict on Postman
An essential tool that every developer working with APIs must have on their machine.
