Rewriting Localhost: A Modern Approach to Dev Environments
summary
Demonstrates exact setups and tradeoffs: puma dev auto-wires .test names and gives zero-config HTTPS for Rack/Puma apps but no Docker support and only works for Puma-based servers; using dnsmasq + Caddy handles wildcard local domains, supports Docker and language-agnostic reverse proxying, and provides automatic HTTPS via Caddy TLS internal, with practical notes on /etc/resolver and brew services. Nginx works too but requires more manual TLS and proxy config.
