Where each one falls short

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

Greasemonkey

  • Firefox only. There is no Chrome, Edge or Safari build and there never has been.
  • Its API diverged from the Tampermonkey conventions most shared scripts are written against, so a script from a sharing site may need adjusting to run.
  • The dashboard is plainer than Tampermonkey's, with no diff view when a script updates itself.
  • No cloud sync of the kind Tampermonkey and Violentmonkey offer; moving machines means exporting.
  • A userscript manager can read and rewrite every page you visit, so the security of the arrangement depends entirely on the scripts you choose to install.

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
