The short version

  • Each has a real cost: Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration; WordPress self-hosted installation requires PHP 8.3 and MySQL 8.0 or MariaDB 10.11 minimum; older versions expose security vulnerabilities
  • They diverge on capability: Read the Docs covers Build on commit, WordPress covers Content management.

Where each one falls short

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

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

WordPress

  • Self-hosted installation requires PHP 8.3 and MySQL 8.0 or MariaDB 10.11 minimum; older versions expose security vulnerabilities
  • Requires web server (Apache or Nginx) setup and ongoing maintenance; not suitable for serverless deployment
  • HTTPS mandatory for all installations; HTTP-only setups are not supported
  • Self-hosting requires responsibility for security patches, backups, and server administration
