- Some advanced setups need plugins
Insomnia: pros & cons
- Clean interface that stays out of the way

Our verdict on Caddy
The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
Our verdict on Insomnia
A lighter alternative to Postman. If your team already lives in Postman collections, switching costs more than it saves.
