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'; Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration
- They diverge on capability: Nginx covers High-performance web server, Read the Docs covers Build on commit.

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
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle
