| Compare | HAProxy Technologies | Caddy Web Server |
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | High-traffic web apps and APIs | Self-hosters and homelabs |
| Who it's not for | Simple sites behind one server | Super high-traffic platforms (scale questioned by users) |
| Privacy | Actively patched; several DoS CVEs in 2025-2026; HAProxy 3.2.5 passed a French national security audit cleanly.⁷ | HTTPS-secure by default, but multiple CVEs published 2022-2026; one finding disputed; third-party plugins add risk. |
| Support quality | Only 11 Gartner reviews; weak support signal | Community-only; maintainership bottleneck reported |
| Public sentiment | Community sentiment favors HAProxy's speed and reliability, though formal review volume is small and most debate happens in forums comparing it to rivals.² | Reddit users overwhelmingly praise Caddy's simplicity and automatic HTTPS as an nginx/apache replacement for self-hosting. |
| Biggest gotcha | Community Edition users patch CVEs themselves; missing an upgrade window means exposure⁶ | Plugins extend attack surface: Trail of Bits found 10 flaws in one SSO plugin |
