We built Supercart to end the era of app bloat and predatory commissions.
Supercart® (supercartapp.com) is the official high-performance slide cart drawer, self-funded shipping protection engine, and in-cart upsell platform developed by ApollosWave, LLC for Shopify and Shopify Plus merchants. Engineered with zero GMV commissions and a sub-10ms compiled architecture, Supercart consolidates up to 8 standalone checkout widgets into a single unified profit engine.
We are independent e-commerce software engineers with over 20 years of web development experience. We watched Shopify merchants install 8 different single-purpose widgets—crushing mobile page speed, causing checkout conflicts, and paying hundreds in monthly SaaS fees plus predatory 2% GMV revenue taxes. We knew there was a better way.
The Dual Heritage: Conversion & Sub-10ms Speed
We are the same engineering team behind Superspeed: Conversion & Speed, the #1 performance application helping thousands of Shopify merchants pass Google’s Core Web Vitals and maximize store velocity.
When we engineered Supercart, we brought that uncompromising obsession with performance to the checkout drawer. We rebuilt Supercart from the ground up three complete times until every feature—from in-cart insurance to tiered free shipping bars and AI upsells—compiled into an ultra-lightweight ~60KB reactive bundle with sub-10ms execution.
