| Compare | HAProxy Technologies | nginx |
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | High-traffic web apps and APIs | High-traffic web apps |
| Who it's not for | Simple sites behind one server | No-code founders wanting a GUI . it's config files only |
| Privacy | Actively patched; several DoS CVEs in 2025-2026; HAProxy 3.2.5 passed a French national security audit cleanly.⁷ | Actively maintained and patched by F5, but hit by several critical 2026 CVEs, some actively exploited. |
| Support quality | Only 11 Gartner reviews; weak support signal | Only commercial support availability documented, not quality |
| 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 | Users consistently praise nginx as fast, lightweight, and an excellent reverse proxy, while grumbling about config complexity and NGINX Plus pricing.12 |
| Biggest gotcha | Community Edition users patch CVEs themselves; missing an upgrade window means exposure⁶ | 2026 CVEs actively exploited in the wild; patching is on you16 |
