Built for Scale
Engineering the performance gap.
Competing plugins use meta queries on raw wp_postmeta. FilterX uses a purpose-built index — that's the difference between 2 seconds and 200ms.
Index-Powered Engine
FilterX maintains a dedicated filterx_index table. Every filter request queries the index — not the full wp_postmeta. The result? Sub-200ms filtering on catalogs with 100,000+ items.
Visual Card Builder
Drag 12 block types onto a canvas. Design the exact card layout you need — images, title, taxonomy badges, WC price, and custom HTML. Zero PHP templates needed.
API-First Design
Every feature is exposed via 31 clean REST endpoints. Build headless storefronts, custom mobile apps, or extensive React-powered integrations.
12 native facets.
Zero lag.
Every facet maps to any data source — taxonomy, post meta, ACF, or WooCommerce — and queries the pre-built index instantly.

Live in 3 steps.
From install to production filtering — no coding required.
Create Facets
Go to FilterX → Facets, click New. Pick a type — Checkbox, Range, Color — and map it to any post meta, ACF field, or WooCommerce attribute.
Indexing starts automatically.
Build Your Grid
Create a Grid at FilterX → Grids. Choose your post type, pick a layout (Grid, Masonry, List), set columns, and design the card template visually.
Drag-and-drop card builder.
Embed Anywhere
Drop a shortcode, Gutenberg block, or Elementor widget onto any page. Visitors see instant results — no page reloads.
Live AJAX updates.
WooCommerce filtering
done right.
FilterX auto-activates when WooCommerce is detected. No setup required — just pick your product attributes and go.
// Fetch filtered grid results
const res = await fetch('/v1/grids/shop');
const {
html, // Rendered HTML
total, // Counts
found_posts // IDs
} = await res.json();
if (total > 0) {
grid.update(html);
}Headless ready.
31 REST endpoints.
Every FilterX operation is exposed as a clean REST endpoint. Build React frontends, custom mobile apps, or extensive integrations — all on top of the same foundation.

FilterX uses modern PHP 8.1+ patterns throughout — not WordPress spaghetti.
DI Container
PSR-11 compatible dependency injection. Services are resolved once and cached — zero reflection overhead.
Service Providers
Modular registration pattern. Each service (Facets, Grids, Cache) registers exactly what it needs.
6 Custom Tables
filterx_index, filterx_facets, filterx_grids, filterx_queue... Zero options-table bloat.
Async Queue
Custom background queue table drives all bulk indexing. Configurable batch sizes and cron support.
Typed PHP 8.1+
Enums, first-class callables, and intersection types. The codebase treats type safety as non-negotiable.
Fast Admin Panel
Modern, app-like settings interface. Full CRUD for facets and grids without slow page reloads.

Filtering that Google
actually crawls.
Most filter plugins create "crawl traps" or thin content. FilterX is engineered to handle SEO at the core, ensuring your filtered pages contribute to your rankings.
Clean Permalinks
Transform ?fx_color=red into /filter/color-red/ automatically. Readable, crawlable, and shareable URLs.
Intelligent Canonicals
Automatic canonical tag normalization prevents duplicate content penalties from multi-select filters.
Automated JSON-LD
Generates Schema.org ItemList and Product snippets for filtered results out of the box.
Crawl Depth Control
Automatically sets 'noindex' on overly complex filter combinations to preserve your crawl budget.
