Choose Caddy if:
Anyone who wants a correctly configured HTTPS server without ceremony.
Choose Clerk if:
Product teams who would rather ship features than build authentication.
Caddy: pros & cons
- HTTPS configured correctly by default
- Configuration is short and legible
- Single binary, easy to deploy
- Smaller community than nginx
- Fewer third-party guides
- Some advanced setups need plugins
Clerk: pros & cons
- Prebuilt UI components that look decent by default
- Handles sessions, MFA and organisations
- Strong React and Next.js support
- Pricing per monthly active user adds up
- Deep customisation fights the defaults
- Auth becomes a vendor dependency
Our verdict on Caddy
The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
Our verdict on Clerk
A big time-saver early on. Understand the per-user pricing curve before your user count grows.
