  • They diverge on capability: Rollup covers Tree shaking, WordPress covers Content management.
  • 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.

Rollup

  • Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
  • Configuration for non-trivial applications gets verbose compared with tools that assume more

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
