WooCommerce Plugin Compatibility Checker

Paste up to 6 plugin slugs (the part of the URL after wordpress.org/plugins/) and this tool reads each one's public WordPress.org listing: the PHP version it requires, the WordPress version it's tested up to, how recently it was updated, and a text search of its description and changelog for mentions of High-Performance Order Storage (HPOS) or the cart/checkout blocks.

That text search is a heuristic, not a real compatibility check: a plugin can be genuinely HPOS-compatible without the word "HPOS" appearing anywhere in its listing, and mentioning it doesn't guarantee compatibility either. The only fully authoritative source is your own site.

1. 01

   Go to WooCommerce → Settings → Advanced → Features

   Scroll to Order Data Storage. WooCommerce lists every active plugin as compatible, incompatible or unknown, based on what each plugin actually declares.

2. 02

   Update or replace anything flagged incompatible

   WooCommerce won't let you enable HPOS while an incompatible plugin is active.

3. 03

   Use this tool first to triage

   Before you even install a plugin, or when you're comparing two alternatives, to see which is more actively maintained and more likely to already support HPOS.

• Paid plugins sold outside WordPress.org (most premium WooCommerce extensions) aren't in this directory at all; check their own changelog or support page instead.
• A plugin that hasn't updated in over a year and a half isn't necessarily broken, but it's meaningfully more likely to be unmaintained and untested against current WooCommerce and PHP.
• "Tested up to" is the WordPress version the developer last tested with, not a guarantee of compatibility with your exact combination of plugins and theme.
