Why other filters feel slower

Most filter plugins ask the server for new results on every click. InstantFilter already has everything in the browser.

Traditional filters

AJAX
Time per filter click 600–2,000 ms Waiting on the server, on every click
  1. A visitor clicks a filter
  2. AJAX request to the server
  3. PHP and a database query on every click
  4. A new product grid sent back to the browser

InstantFilter

Frontend-first
Time per filter click 25–50 ms Instant results, no server request
  1. A visitor clicks a filter
  2. The browser filters the results immediately
  3. The result shows up right away

What your shop gets from InstantFilter

No more loading spinner

Results show up immediately on every click, even on catalogs of 50,000+ products.

Less load on your server

Filtering runs on the visitor’s device. No PHP or database query per click, even on busy campaign days.

Variations as separate cards

Explode mode shows each color or size as its own product card. No extra add-ons.

Style the card, grid and sidebar From Pro

Use the visual Style builder for your product card, product grid, and filter sidebar. No PHP templates or custom CSS.

Built for developers

Set up filters in minutes, not hours.

Set up hundreds of attribute filters at once

Loop every global or custom attribute and create the checkbox filters in one go.

Pick custom or global attributes, leave out the ones you do not need, and set the sort order, all from one screen.

No manual setup per attribute. Configure it once and you are done.

Common questions

InstantFilter builds a product index in the browser in the background. When a visitor clicks a filter, it searches only that index, with no database query and no request to the server.
InstantFilter is built for WordPress and WooCommerce only. Install it like any standard plugin, activate your license, and place a shortcode on a shop or landing page. It works with any WooCommerce theme.
Usually no. After the first setup, InstantFilter keeps the items table in sync through WordPress hooks when you save, update or delete products — including variations. Run Reload Products manually only after a large bulk import or if the Items count drifts from WooCommerce.
The first view is rendered on the server (SSR) and can be stored by your page cache. After that, the compressed export loads in the browser and filter clicks are handled on the client. Export size depends on your catalog: test it on staging with your real product count.
Yes. You can test the full Pro version free for 14 days via our free trial download — only your email address is required, no credit card or payment info needed. Looking to purchase immediately? See our Founders pricing (includes a 30-day money-back guarantee).
Yes. Upgrade or downgrade any time from the Lemon Squeezy customer portal. Upgrades are pro-rated — you only pay the difference and new limits unlock immediately.
