Description

Fast Cart is the ultimate lightweight WooCommerce Ajax Side Cart and Slide Cart plugin designed to deliver a blazing-fast, high-converting shopping experience. Upgrade your store with an interactive sliding cart drawer, floating cart icon, and dynamic free shipping bar. And best of all?

Awesome plugin, works like a charm. I was in need of some customisation with the MOBILE rendering of the side cart Reza found quickly the workaround and correct the bug, I’m very grateful for the prompt & PRO assistance!! Keep up the good work guys!!

Very Happy with this plugin : light, nice and great level of support . I wanted to fine tune some elements not in the native way and the support helped me to achieve it ! 6 stars

Atom Adam November 20, 2025

I’ve used other side cart plugins for several years, but was looking for something more lightweight (my last one loaded about 98kb of css/js on every page). I was super happy to find Fast Cart, as it works perfectly and is far less bloated (only 16.2kb of css/js loaded!). Great plugin.

udoe November 17, 2025

I really love this “site cart plugin”, as it offers the user a nice and helpful overview of the shopping card, each time you add a product – without having to open the shopping card site. Since there was an issue with relatively long product descriptions, my support request was handled and solved very quickly! Once again thanks for this plugin and for your awesome support 🙂

Thomas Sheldon February 26, 2023

Adding items to the cart without reloading a specific page is advantageous. Hopefully, this cart plugin will help my store deliver a better customer experience.
