Magento Theme Development and Installation

Custom Magento themes designed from scratch in Figma and built on Luma or Hyvä, or marketplace themes installed and configured the right way.

Your storefront

Magento theme development that stays maintainable

Magento theme development shapes how customers see your brand and how easily your team can change the store later. Many stores run a purchased theme that was edited directly, which breaks on every update. We install and build themes so design changes, Magento upgrades and new features can happen without rework.

For marketplace themes, our Magento theme installation follows the vendor’s instructions and adds a child theme for your customizations. Core and vendor files stay untouched. For custom Magento theme development, we design and build on Luma or on Hyvä, depending on your goals, budget and extensions. See our Hyvä theme development page for the Hyvä option in detail.

Our workflow is AI-assisted and centrally managed. AI tools draft components, check templates against coding standards and run accessibility and performance checks. Frontend engineers review the output, make the design decisions and approve every change before it is merged. You see progress on a staging store throughout the project.

Designing from scratch means we start with your brand and customers: a Figma design and a small design system first, then a theme built for it, so every page, block and component stays consistent.

FAQ

Magento theme development FAQ

Luma is the default Magento frontend and most extensions support it out of the box. Hyvä replaces much of Luma’s frontend JavaScript with a lighter stack, which often makes it easier to reach good performance, but some extensions need Hyvä compatibility modules. We check your extension list during the audit and recommend the option that fits. See our Hyvä theme development page for details.

Yes. To install a Magento theme properly, we follow the vendor’s documentation, install it with Composer where available and create a child theme for your changes. We also check compatibility with your Magento version and extensions on staging first, so the live store is not affected while we configure it.

Yes. We compare your theme and Magento files with the original versions to find every modification. Changes are then moved into a child theme or a custom module, and the original files are restored. This makes future upgrades and security patches far safer to apply.

Yes. We build Page Builder blocks and content types matched to your design system, so your team can create landing pages, banners and content sections without a developer. We document each block and include a short training session at handover.

We agree a performance budget at the start, covering JavaScript, CSS, fonts and images. Each release is checked against it on staging, and AI tools flag regressions for an engineer to review. Optimized images, lazy loading and limited third-party scripts are part of the build.
