The short version

  • Only Nginx has a free tier, so it costs nothing to try first.
  • 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'; Redocly only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
  • They diverge on capability: Nginx covers High-performance web server, Redocly covers OpenAPI reference docs.

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

Redocly

  • Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
  • The portal and governance features are paid, while the open-source renderer covers only reference rendering
  • Linting rules are another thing to configure and argue about before value appears
  • Narrower than a general documentation platform, by design

Answered from the vendors’ own pages

Nginx: How much does nginx cost?

nginx is free and open source software distributed under the 2-clause BSD License. Enterprise distributions, commercial support, and training are available from F5 Inc. at custom pricing.

Source
Redocly: Is Redocly free?

The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor site.

Redocly: What does the linter do?

It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

Redocly: Do I need OpenAPI to use it?

Effectively yes. Without a maintained specification there is little for it to work with.
