Renderflow — Shopify Theme Store

Renderflow is my own product rather than a client’s. It is a store that sells Shopify themes, and I built every part of it: the storefront, the themes on sale inside it, the illustrated guide that ships with each one, and the support address behind them. It has been live since September 2026.

The first theme is Vantage, a storefront built for a clothing brand. Search, cart, customer accounts and an FAQ are part of the theme, so none of them arrives as a paid app on the merchant’s monthly bill. It sells for €89 at launch price, going to €129 afterwards, and comes with four demo products and their sixteen royalty-free photos — enough that a new store looks like a store within minutes of installing, instead of showing an empty grid.

Selling a theme means writing code somebody else will edit, which changes how it has to be written. Shopify’s editor lets a merchant add and move sections without reloading the page, so each section registers its own behaviour instead of binding once at load — skip that and every section added after the first page view sits dead, which is the single most common reason a theme is rejected. Movement stays on transform and opacity, the two properties the browser can hand to the GPU, because the Theme Store requires a performance score of at least 60 and animating anything that triggers layout puts it out of reach.

The storefront around the themes is hand-built rather than a Shopify template: the transitions between pages, the cart that opens as a drawer over the page instead of replacing it, and the curve that bends as the menu opens. Two of the three shelves read “incoming” on purpose — a shelf with room on it says more than one product alone in the middle of a page.
