Reviewer scorecard
“Automatic HTTPS and the Caddyfile syntax make web server config trivial. Reverse proxy setup is one line.”
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“Automatic HTTPS alone justifies switching from Nginx. The Caddyfile is infinitely more readable than nginx.conf.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“Caddy proves that web servers can be simple. Automatic HTTPS should have always been the default.”
“Fly.io is the answer for workloads that don't fit the serverless model. As AI inference goes local-first, having servers in 30+ regions matters.”
