Reviewer scorecard
“Automatic HTTPS and the Caddyfile syntax make web server config trivial. Reverse proxy setup is one line.”
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“Automatic HTTPS alone justifies switching from Nginx. The Caddyfile is infinitely more readable than nginx.conf.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Caddy proves that web servers can be simple. Automatic HTTPS should have always been the default.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
