Caddy

  • Adding plugins means rebuilding the binary rather than loading a module
  • Under very high throughput Nginx generally still benchmarks ahead
  • Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments

Wireshark

  • Free and open source under the GNU GPL; downloadable without paying any license fee, no commercial tier
