What you get

Shopify theme development, done properly

Your Shopify theme should help your team sell without calling a developer for every landing page, offer, or product update. Bytecode builds Online Store 2.0 themes with clear sections, blocks, and settings your marketers can use safely.

We work with US DTC brands from our New York studio. You get senior theme development for premium theme customization, fully custom builds, product and collection UX, app extensions, performance, accessibility, and launch QA.

Custom OS 2.0 themes

We build Shopify Online Store 2.0 themes with reusable sections, blocks, templates, and theme settings. Your team can publish new pages without breaking the system.

Premium theme customization

If a premium theme is the right base, we customize it cleanly instead of forcing a full rebuild. You get the changes your brand needs while keeping the theme maintainable.

Product and collection UX

We improve product pages, collection pages, filters, media, variant flows, bundles, and offer presentation. The goal is a clearer path from browsing to checkout.

Speed and Core Web Vitals

We set a speed budget, reduce theme bloat, review scripts, and test real templates. We do not chase vanity scores at the cost of useful store features.

App-safe theme work

When an app needs theme UI, we prefer app blocks and theme app extensions over hard-coded snippets where Shopify supports it. That makes updates safer and easier to debug.

Launch QA and handoff

We test key devices, browsers, templates, checkout paths, tracking, forms, accessibility basics, and theme settings before launch. Your team also gets a clear handoff.

FAQ

Questions, answered

Should we customize a premium Shopify theme or build a custom theme?

It depends on how far your requirements are from the theme you like. A premium theme can be a good base if the layout, settings, and code quality match your needs. A fully custom theme is better when you need tighter control over UX, performance, editing rules, and brand-specific flows.

Can marketers edit the theme without a developer?

Yes, that is a core part of the build. We create Online Store 2.0 sections, blocks, templates, and settings so your team can update content safely. We also limit settings where too much control would create layout or performance problems.

How do you handle site speed and Core Web Vitals?

We start with a speed budget and review theme code, images, apps, scripts, fonts, and template structure. We focus on the pages that matter most, such as product pages, collections, landing pages, and the home page. We cannot guarantee specific scores, but we build with performance in mind from the start.

Can you work with our existing Shopify apps?

Yes. We review the apps already in the store and how they touch the theme. Where possible, we use Shopify app blocks and theme app extensions instead of hard-coded snippets. That makes the theme easier to update and lowers the chance of hidden conflicts.

Do you handle accessibility?

We include accessibility basics during design and development. That means attention to headings, labels, keyboard use, color contrast, focus states, and usable interactive elements. If you need a formal legal audit, we can help prepare the theme for review by the right specialist.

Can you help after launch?

Yes. We can support fixes, new sections, landing pages, app changes, performance reviews, and UX improvements after launch. Many stores need iteration once real customers and campaigns hit the new theme. We keep the theme maintainable so future work is less painful.
