FunnelKit Review (2026): We Tested Every Free FunnelKit Plugin

FunnelKit (formerly WooFunnels) is a family of WooCommerce plugins: a funnel and checkout builder, an email automation CRM, a sliding side cart, a Stripe payment gateway and a block library. Most reviews only look at the funnel builder. In this FunnelKit review we installed every free FunnelKit plugin from WordPress.org on the same clean WooCommerce store, one at a time, and measured what each one adds to your pages, your server and your dashboard.

FunnelKit plugins at a glance

FunnelKit review: performance test results

Each plugin was activated alone on a clean WooCommerce store. We measured the home, shop, cart and blog pages for a logged-out visitor.

The pattern is clear: FunnelKit keeps your storefront clean. Not one plugin added a CSS or JavaScript file to the shop pages straight after activation (the gateway added 0.3 KB of inline settings on the cart page). The cost is on the server side. Funnel Builder added 12.1 MB of PHP memory on the front end, the Stripe gateway 6.9 MB, and Automations 4.7 MB with WooCommerce active. The Sliding Cart and SlingBlocks were almost free: 0.1 MB each.

1. FunnelKit Funnel Builder

8.6/10 Free plan v3.18.0 · 30,000+ installs · 5.0★ on WordPress.org

Download: FunnelKit Funnel Builder on WordPress.org.

Funnel Builder is the core plugin. The free version replaces the WooCommerce checkout store-wide with conversion-focused templates, adds a drag-and-drop checkout field editor, and lets you build opt-in pages, sales pages and custom thank-you pages. It integrates with Elementor, Divi, Bricks, Oxygen and the block editor.

After activation it showed a “Quick Setup” notice, a dashboard widget and an admin-bar menu. It registered five content types (checkout, landing, opt-in, opt-in thank-you and thank-you pages), created 10 tables and saved 35 options. Order bumps, one-click upsells, multi-step checkouts, A/B tests and revenue analytics are Pro. Compare it with the alternatives in our best WooCommerce funnel builder test.

2. FunnelKit Automations

9.3/10 Free plan v3.9.0 · 20,000+ installs · 5.0★ on WordPress.org

Download: FunnelKit Automations on WordPress.org.

Automations is FunnelKit’s email marketing and CRM plugin. The free version tracks abandoned carts, includes ready-made recipes and a visual workflow builder, and stores unlimited contacts. Its only free action is “send email”, and broadcasts, audiences and SMS are Pro features, which the dashboard makes clear with “Upgrade to PRO” labels.

With WooCommerce active it added 4.7 MB of memory, 33 tables and 4 cron jobs, and it created 2 pages for email preferences. Without WooCommerce it used 3.9 MB. See how it stacks up in FunnelKit Automations vs FluentCRM.

3. FunnelKit Sliding Cart

9.6/10 Free plan v1.9.1.2 · 30,000+ installs · 5.0★ on WordPress.org

Download: FunnelKit Sliding Cart on WordPress.org.

The Sliding Cart replaces the “added to cart” redirect with a drawer that opens from the side, so shoppers can change quantities, apply a coupon and go straight to checkout. The free version includes the floating cart icon, styling controls, quantity editing and a coupon box. Upsells, cross-sells and milestone rewards (free shipping or a gift at a cart total) need Funnel Builder Pro.

It is the lightest FunnelKit plugin: 0.1 MB of memory, 2 tables and no files on your pages until you switch the cart on under FunnelKit > Cart. Our side cart test compares it with XootiX and WPC Fly Cart.

4. FunnelKit Stripe Gateway

9.1/10 Free plan v1.16.0 · 20,000+ installs · 4.9★ on WordPress.org

Download: FunnelKit Stripe Gateway on WordPress.org.

FunnelKit’s free Stripe gateway supports cards, Apple Pay, Google Pay, Link, Amazon Pay, Klarna, Affirm, Afterpay and many local methods, with automatic webhook setup and a test mode only admins see. Its main advantage is that one-click upsells from Funnel Builder Pro work with it out of the box. Stripe’s own fees apply; the plugin does not list any extra fee of its own.

In our test it added 6.9 MB of memory, 24 options and a “quick set up” notice that links to its onboarding screen. Compare it with WooCommerce’s official Stripe plugin in our Stripe plugins test.

5. SlingBlocks

9.4/10 Free plan v1.8.1 · 6,000+ installs · 5.0★ on WordPress.org

Download: FunnelKit SlingBlocks on WordPress.org.

SlingBlocks adds landing-page blocks (testimonials, pricing, icons and more) to the block editor. It added 0.1 MB of memory, no tables and no files until you use a block. It is the least maintained FunnelKit plugin: last updated in May 2026 and tested up to WordPress 7.0. If you build pages with Elementor or Bricks, you can skip it.

FunnelKit pricing

All five plugins are free on WordPress.org. FunnelKit’s paid plans bundle the Pro versions. On funnelkit.com in November 2026 the first-year prices were Basic $99.50 (1 site), Plus $179.50 (2 sites), Professional $249.50 (3 sites) and Elite $399.50 (30 sites). Renewals cost more than the first year, so check the renewal price before you buy. FunnelKit Automations is also sold on its own from $99.50 a year.

FunnelKit pros and cons

Who should use FunnelKit?

• WooCommerce stores selling digital or physical products that want a better checkout and post-purchase offers.
• Course and coaching businesses on WooCommerce that need opt-in funnels and follow-up emails.
• Agencies building funnels for clients, with the 30-site Elite plan.

If you do not use WooCommerce, FunnelKit is the wrong tool; look at a CRM like FluentCRM and a page builder instead. And if you only need a checkout and a cart drawer, the free plugins alone go a long way.

FunnelKit review: what to check before you buy

Every FunnelKit review ends with the same question: is the free version enough, or do you need Pro? Use this checklist.

• Do you use WooCommerce? FunnelKit is built for it. Without WooCommerce, only the opt-in pages and Automations are useful.
• Do you sell more than one product? Order bumps and one-click upsells (Pro) make the most money when you have complementary products.
• Which page builder do you use? Funnel Builder has native templates for Elementor, Divi, Bricks, Oxygen and the block editor.
• Does your gateway support upsells? FunnelKit Stripe and PayPal support one-click upsells; many third-party gateways do not.
• Can your hosting handle it? Funnel Builder added 12 MB of PHP memory per request in our test, so avoid the smallest shared plans.

How we tested

Every plugin was installed from WordPress.org on a clean WordPress 7.1.4 site (PHP 8.3, Kadence theme) in WordPress Playground in November 2026. We activated one plugin at a time, measured the site, then deactivated it again, so each result is compared with the same baseline.

We loaded the home page and a normal blog post as a logged-out visitor three times and kept the median PHP peak memory, added up the CSS and JavaScript files the plugin added, and recorded database tables, options, scheduled cron jobs, admin menus, notices, dashboard widgets and any redirect on the first admin visit.

Screenshots were taken on the same test site right after activation. Ratings, installs and versions come from the WordPress.org plugin directory on the same day. WooCommerce 11.2.2 was active with four sample products. Automations was also tested without WooCommerce.

The WPGlory score rates what a plugin costs your site, not how many features it has: front-end weight 30%, server cost 20%, admin clutter 20%, WordPress.org rating 20% (weighted by the number of reviews) and maintenance 10%. Features are covered in the text. Read the full method.
