QuantThemes turns your brand brief into a Theme-Store-quality storefront. You approve the design first — then watch your theme get built live. Fully editable, three complete presets included, at a fraction of agency prices.
Design approved before anything is coded · Fully editable in Shopify · No lock-in
Not weeks of back-and-forth. Not a queue behind someone else's project. You brief us, approve the design, and your finished theme is ready in a day or two.
Built to the same standard real Theme Store submissions must meet — clean, fast, accessible. Never "depends who's free this week." Consistent, every single time.
Genuinely affordable for a fully custom, on-brand theme — finished in two days, built to your wishes, fully editable, with three presets included. Agency result, without the agency invoice.
No black box. You can watch each phase happen — and nothing gets coded until you've signed off on the look.
Fill out a short, guided brief: your industry, brand vibe, colors, typography, and the pages and features you need. Ten minutes, no design jargon required.
Our system generates a complete visual design direction from your brief — layouts, palette, typography, atmosphere. Built around your brand and your logo, not a stock template.
You review the design and approve it. Nothing gets built until the look is signed off. If it's not right, it's not going forward.
Once approved, the production Shopify theme is built to match — pixel-faithful to the design you signed off on. You can watch it happen in real time.
A dedicated QA team — automated agents plus a supervising staff agent — verifies everything was generated correctly, screenshots and tests every page, then transfers and configures the theme in your store and handles any custom requests.
Most theme work is a black box: you brief someone, you wait, you hope. QuantThemes is the opposite. You see the design generated from your brief, you approve it, then you watch the actual theme get built from that approved design — live. Transparent from first pixel to final handoff.
The look is generated and approved before a single line is coded.
The theme is built to match the approved design — not a generic template wearing your colors.
A staff agent oversees the whole run, tests every page, and configures the finished theme in your store.
Every theme ships with 3 complete aesthetic presets — palette, type, atmosphere over the same code. Swap the whole look with one action.
Everything visual is a theme setting — colors, fonts, layout, sections — all in Shopify's native editor. No lock-in, no dev needed.
Trained on Shopify Theme Store rules and best practices, so your theme meets the same bar as real submissions.
Automated QA agents plus a supervising staff agent verify, screenshot and test every page, then configure and hand off.
WCAG-minded markup, semantic structure, keyboard navigation, and ARIA — part of how the theme is built.
Clean semantic HTML, structured data and metadata, tuned for Core Web Vitals — strong LCP, minimal blocking JS.
Lightweight by default. No bloat, no app-soup, no drag — fast pages that keep shoppers moving to checkout.
You provide the brief and logo; the theme is designed around it. The result looks like your store — because it was.
You want a custom, on-brand Shopify theme that looks like you spent agency money — without spending it, or waiting weeks. Brief us, approve the design, and launch a store you're proud of in days. Then edit anything yourself, anytime.
Take on more theme work without growing headcount or blowing timelines. Custom, Theme-Store-quality builds your clients sign off on — in 1–2 days, ready to hand over as your own. Your dev team stays focused on the work only they can do.
Add a premium, fully custom theme service to what you already sell — without hand-coding every project. Brief, approve, deliver, and keep the margin. Consistent quality you can put your name on.
Agencies and freelancers vary — by workload, availability, and whoever gets assigned. They take too long and cost too much. QuantThemes is fast, affordable, and the quality is the same high level every time.
