The short version

  • Each has a real cost: Nginx open-source nginx has no admin API for changing arbitrary config at runtime; dynamic reconfiguration requires editing the config file and reloading via 'nginx -s reload'; Preact compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • They diverge on capability: Nginx covers High-performance web server, Preact covers 3kB runtime.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nginx

  • Open-source nginx has no admin API for changing arbitrary config at runtime; dynamic reconfiguration requires editing the config file and reloading via 'nginx -s reload'
  • No official built-in GUI or dashboard for management or live metrics in the open-source edition
  • Advanced capabilities such as active health checks, dynamic upstream reconfiguration without reload, and a full API gateway feature set are exclusive to the paid NGINX Plus product, not open-source nginx
  • No published list price for NGINX Plus on the current F5 product page; pricing requires contacting sales

Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React

Preact: Can I use React libraries with Preact?

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.

Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.
