What commenters say

• Caddy is a viable replacement for NGINX and Apache, offering a simpler configuration and robust features.
• The marketing tone of the Caddy website is off-putting and lacks technical details.
• Caddy's automatic HTTPS feature is a game-changer for local TLS setups, but may require exposing port 80 and 443 to the public internet.
• Using Caddy with FrankenPHP can significantly improve PHP application performance, but may require disabling worker mode in some cases.
• HTTP/2 requires encryption, which can be a challenge for local development, but Caddy's automatic HTTPS can help alleviate this issue.
• Some commenters find Caddy's features and simplicity to be a major advantage, while others are concerned about the potential risks of trusting self-signed certificates.
• There are workarounds for testing HTTP/2 locally, such as using a regular DNS name or a service like Traefik.me, but these may have their own drawbacks.
• The need to buy a domain and obtain a certificate to test personal projects locally is seen as a significant hassle by some commenters.
