WordPress Plugin Compatibility: What Works with FlatWP

One question we get constantly: “Will my favorite WordPress plugins work with FlatWP?”

The short answer is: most of them, yes. But it depends on what the plugin does.

Plugins That Work Great

Content & SEO Plugins:

• Advanced Custom Fields (ACF) – Full support via WPGraphQL
• Yoast SEO – Meta data accessible through GraphQL
• Rank Math – Similar to Yoast, works perfectly
• Custom Post Type UI – Create custom post types, query via GraphQL

Media & Assets:

• Any media library plugin – Images flow through next/image optimization
• ShortPixel – Optimize before Next.js processes them
• Cloudinary – Can integrate as image source

Forms:

• Contact Form 7 – Works with our form adapter
• WPForms – REST API integration available
• Gravity Forms – GraphQL extension available

Plugins That Need Adapters

Some plugins require custom integration but are totally doable:

WooCommerce: FlatWP Pro will include a headless storefront. You can also use WPGraphQL for WooCommerce for custom implementations.

Multilingual (WPML/Polylang): Works with proper GraphQL queries. FlatWP Pro includes multi-language routing.

Membership plugins: Require custom authentication flow but compatible.

Plugins That Won’t Work

Anything that depends on WordPress themes or relies on server-side rendering:

• Page builders (Elementor, Divi) – Use ACF Flexible Content instead
• Caching plugins (WP Rocket, etc.) – Next.js handles caching
• Theme-specific plugins – Your frontend is React, not PHP

Our Compatibility Roadmap

We’re actively testing and documenting plugin compatibility. Current priorities:

1. WooCommerce integration (in progress)
2. Popular form plugins
3. Multilingual support
4. Events plugins (The Events Calendar)

If there’s a plugin you need, let us know. We’re building adapters based on community demand.
