About

HostlessWP is a free, open-source command-line tool for deploying an existing WordPress site to Cloudflare Workers. It runs PHP 8.3 as WebAssembly while keeping the site's MySQL database, accessed through Cloudflare Hyperdrive or a Cloudflare Tunnel. WordPress core, themes, and plugins are packaged without modifying the source site; media can be stored in Cloudflare R2 or another S3-compatible bucket. A read-only setup check compares active plugins with a tested compatibility list, then deploys a copy to a test address before the owner switches the domain. The 30 most-installed WordPress.org plugins load at page level, and a WooCommerce checkout has been tested end to end. HostlessWP is for WordPress site owners and developers and requires Node.js 20 or newer, a Cloudflare account, MySQL, and an S3-compatible bucket. This early-preview software is licensed under GPL-2.0-or-later and does not yet support multisite or plugin installation from the deployed admin.
