Description
HTML Page Publisher lets you drop a standalone HTML file into WordPress and have it served as a landing page at a clean URL. Works with output from Claude Design and HTML exported from other AI tools like ChatGPT, Gemini, v0, and Bolt, and with any hand-written static HTML too. Perfect for sales collateral, one-pagers, lead-gen pages, and campaign microsites.
Key features
- Simple admin UI: upload one HTML file + its image assets, get a public URL
- Automatic cleanup of AI-export wrappers: strips runtime code some AI HTML export tools inject so the published page is pure static HTML
- Configurable URL prefix: default
/pages/your-slug/, change to anything you like (e.g./resources/,/guides/) - Optional subdomain routing: point
sales.example.comat your site and pages appear atsales.example.com/your-slug/ - Secure by default: nonce-protected forms, capability checks, path-traversal guards, and strict file-extension filtering
- Extensible: use the
htmlpp_sanitize_htmlfilter to add cleanup rules for other AI export formats
Use cases
- Publishing landing pages generated by Claude Design
- Publishing HTML from ChatGPT, Gemini, v0, Bolt, and other AI tools
- Sales collateral (rate cards, one-pagers, proposals)
- Campaign landing pages and microsites
- Rapid-publishing static HTML without touching the theme or FTP

FAQ
-
Where are uploaded pages stored?
-
In
wp-content/uploads/html-page-publisher/<slug>/. Each page has its own directory containing anindex.htmland anassets/folder for images. -
How do I use the subdomain feature?
-
Two steps:
- DNS: Add an A or CNAME record pointing your subdomain (e.g.
sales.yourdomain.com) at the same server as your WordPress site. - Web server: Configure your hosting to serve that subdomain from the same WordPress install. On shared hosting with cPanel this is typically an “addon domain” or “subdomain” option. On managed hosts, you may need to request it from support.
Then enter the hostname in HTML Pages Settings Subdomain. Pages will be served at
https://sales.yourdomain.com/your-slug/in addition to the regular prefix URL. - DNS: Add an A or CNAME record pointing your subdomain (e.g.
-
Is it safe to upload arbitrary HTML?
-
Only users with the
manage_optionscapability (administrators by default) can upload pages. Uploaded HTML is served as-is, including any<script>tags it contains, so only upload HTML you trust. The plugin strips known runtime wrappers injected by some AI export tools but does not otherwise filter markup. -
Will uninstalling delete my pages?
-
No. Uninstalling removes the plugin’s settings but leaves the uploaded pages in
wp-content/uploads/html-page-publisher/intact. Delete that folder manually if you want to remove them. -
Does this work with caching plugins or a CDN?
-
Pages are served via a direct PHP readfile that happens before WordPress’s main query runs. Most page caches (WP Rocket, W3 Total Cache) won’t cache these URLs by default. If you want them cached at the CDN edge, add the URL pattern to your caching rules. They’re plain HTML with cache-friendly headers.
