- Handles enterprise SSO requirements that block deals
- Extensive protocol and standards support
- Well documented and widely known
- Expensive as active users grow
- Configuration surface is large
- Migration away is difficult once embedded
Caddy: pros & cons

Our verdict on Auth0
The safe answer for enterprise identity. For a consumer app with simple needs it is more platform than you need.
Our verdict on Caddy
The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
