Your Magento store is slow. You know it. Your customers feel it. Every second of delay costs you sales you will never see. Hyvä fixes that at the frontend level, but only if it is built by developers who know the framework properly. KiwiCommerce is an official Hyvä Bronze Partner, one of a small number of UK agencies to hold that status. When you hire Hyvä developers from our team, you get specialists who have built Hyvä stores from the ground up and migrated established Magento stores without losing data, rankings, or revenue.
Hyvä is a Magento-specific framework. The decision to adopt it is usually triggered by a specific problem: a slow store, a failing Core Web Vitals audit, a conversion rate that should be higher than it is, or a development team that has told you the existing Luma theme is becoming too expensive to maintain. We work with businesses at every stage of that journey.
Get In TouchYour Lighthouse score is in the 30s or 40s. Page load on mobile is above three seconds. You know performance is costing you conversions, but you are not sure whether the problem is the theme, the server, or both. Our Hyvä developers assess both and tell you honestly what will actually fix it.
You have a client who needs Hyvä development, and your team does not have the expertise in-house. We work as your white-label Hyvä partner. Your client sees your brand throughout. We built the Hyvä theme correctly under your name.
Moving an existing Magento store from Luma to Hyvä is not a simple theme swap. Custom modules need compatibility checking. Extensions may need rework. Our Hyvä developers manage the entire migration process without downtime, SEO damage, or data loss.
High-traffic Adobe Commerce stores with complex catalogues, B2B configurations, and heavy custom modules. Our senior Hyvä developers have migrated and built stores at enterprise scale and understand where the real complexity in a Hyvä project sits.
Magento's default Luma theme was built on a frontend stack that made sense in 2015. It relies on RequireJS, KnockoutJS, and jQuery frameworks that were standard at the time but have since become the main reason Magento stores load slowly. A typical Luma page loads between 200 and 300 JavaScript and CSS files. A Hyvä page loads around ten. That difference is why Luma stores typically score between 20 and 50 on Google Lighthouse on mobile, while Hyvä stores routinely score 90 or above.
Hyvä was built by Willem Wigman as a modern alternative. It replaces the Luma stack entirely with Tailwind CSS and Alpine.js, two lightweight, modern technologies that give developers clean tools and give customers fast pages. As of November 2025, Hyvä is fully open-source. The framework itself costs nothing. What costs money is the expertise to implement it correctly, because a poor Hyvä migration can break extensions, damage SEO, and slow down rather than speed up a store.
Here is what our Hyvä developers handle:
3+ Experience Years
Suitable for smaller Magento stores making the move from Luma to Hyvä, where the existing module stack is straightforward. These developers work under senior oversight and handle Hyvä theme builds, basic customisation, and standard extension compatibility work. Best suited for stores that need a clean, performant Hyvä frontend without complex custom functionality.
5+ Experience Years
For mid-sized Magento stores with more complex requirements. These developers handle bespoke Hyvä theme design, custom UI component development, and more involved Luma migration work, and third-party module compatibility. They can work independently and make sound technical judgments about the best way to implement Hyvä within your existing store architecture.
5+ Experience Years
Enterprise-level Hyvä work, including Adobe Commerce builds, Hyvä Commerce platform implementation, complex multi-store configurations, advanced performance tuning, and migration of large stores with significant custom module stacks. These developers have built Hyvä at scale, understand the edge cases, and make architecture decisions that hold up long-term rather than creating new problems further down the road.
7+ Experience Years
A developer whose primary focus is on Luma-to-Hyvä migration projects. They carry out thorough pre-migration audits, map custom module compatibility against Hyvä's requirements, plan the migration in stages to minimise risk, and execute the transition without downtime or SEO damage. For stores with a complex existing setup, this is The specialism that removes the most risk from the project.
5+ Experience Years
For stores already on Hyvä that are not hitting the performance scores they should be. These developers audit your existing Hyvä implementation, identify what is slowing things down, and carry out targeted optimisation work. They understand the difference between a server-side performance issue and a frontend issue in Hyvä's Tailwind and Alpine.js layer, and they fix the right thing rather than guessing.
7+ Experience Years
For large Hyvä projects that need proper technical planning before the build begins. These developers design the architecture of your Hyvä implementation: which components to build custom, which Hyvä packages to use, how to handle existing module compatibility, and how to structure the build for long-term maintainability. They reduce risk at the planning stage, which saves significantly more time and cost than discovering problems during development.
KiwiCommerce holds official Hyvä Bronze Partner status. This is awarded by Hyvä.io based on verified delivery experience with the framework, not self-declared expertise. When you hire a Hyvä developer from KiwiCommerce, you are working with a team whose Hyvä experience has been recognised by the people who built the framework.
Every Hyvä developer on your project is based in the UK. You can call them, email them, or run a screen share during working hours without scheduling around a time zone difference. When a Hyvä migration hits a problem on the morning of go-live, someone is available.
Our founder holds Magento Master status, awarded by Adobe to fewer than 60 developers globally. That depth of Magento expertise informs every Hyvä project we take on. Hyvä works within Magento's architecture; you cannot build it correctly without Understanding Magento deeply, and that understanding is at the core of our team.
Hyvä done well achieves Lighthouse scores of 90 and above on mobile. Hyvä done poorly can achieve results not much better than Luma. Our developers build and optimise Hyvä implementations to the standard the framework was designed for. We do not consider a Hyvä project complete until the performance results back it up.
Your codebase, your client relationships, and your project details stay private. We sign non-disclosure agreements as standard. For agencies using us as a white-label Hyvä resource, we operate completely invisibly under your brand throughout the project.
Hyvä migrations in particular carry risk when they are not properly scoped. We carry out a pre-migration audit before committing to a timeline, agree milestones in writing before work starts, and update you on those milestones throughout. You know what is happening and when.
Whether you are starting a new Hyvä build from scratch or migrating an existing In a Magento store, the process is the same. You get a clear picture of scope, cost, and timeline before any work begins, and you know who is doing the work.
Tell us your platform, your current situation, and what you are trying to achieve. For migration projects, it helps to know your Magento version, roughly how many third-party extensions you are running, and whether you have any custom modules. We come back within one business day with an initial assessment and a clear proposal.
For Luma-to-Hyvä migrations, we conduct a proper audit of your existing store before agreeing on a timeline. This identifies which extensions are Hyvä-compatible out of the box, which need compatibility modules, and which need rework. The audit removes the single biggest source of Hyvä project risk: discovering module problems after the migration has already started.
Once the audit is complete, we agree on the full scope, the delivery stages, and the timeline in writing. You know what is being built, what is being migrated, and what the go-live date is. For new Hyvä builds, we do the same without the audit step. Nothing starts without a written agreement on scope.
Your Hyvä developer works through the agreed milestones and updates you on each one. For migrations, we stage the process to allow testing on a non-live environment before anything goes near the production store. You review and approve before anything goes live.
Your new Hyvä store goes live with the performance improvements the framework is built for. We offer retainer-based support after launch, covering Hyvä updates, extension compatibility checks, ongoing performance work, and new feature development. You have a Hyvä-certified team looking after your store rather than handing it over and hoping nothing breaks.

Hyvä is a modern frontend framework for Magento 2, built as a replacement for the default Luma theme. Luma was designed over a decade ago and relies on heavy JavaScript frameworks, RequireJS, KnockoutJS, and jQuery, which cause slow page loads. A standard Luma store loads 200 or more JavaScript and CSS files. A Hyvä store typically loads fewer than twenty. That difference is why Luma stores often score between 20 and 50 on Google Lighthouse on mobile, while Hyvä stores built properly score above 90. Faster stores convert better, rank higher in search, and cost less to maintain. As of November 2025, the Hyvä framework is fully open-source and free to use.
Hyvä Theme is the original frontend framework that replaces Luma on Magento 2. Hyvä Commerce, released in 2025, is a broader platform that extends Hyvä into a more complete eCommerce solution, including an improved checkout, CMS tools, and a full suite of storefront components. If you are migrating from Luma, Hyvä Theme is the starting point. If you are building a new store or undertaking a significant rebuild, Hyvä Commerce may be the better foundation. We can advise on which is the right option for your specific situation.
It carries real risk if it is not done properly. The most common problem is extension compatibility. Most Magento extensions are built for Luma. Some work with Hyvä out of the box, some need a separate Hyvä compatibility module, and some need custom work to function correctly. A poor migration skips this audit step and discovers problems after the store has already switched over. Our process starts with a full compatibility audit before any migration work begins, which removes the biggest source of risk. The store is migrated and tested in a staging environment before anything touches the live site.
This depends on the complexity of your existing Magento store. A straightforward store with a manageable number of standard extensions can be migrated to Hyvä in four to eight weeks. Larger stores with significant custom module stacks, bespoke checkout implementations, or complex catalogue structures take longer, sometimes twelve weeks or more. We carry out a pre-migration audit, which gives us an accurate picture of the work involved before we commit to a timeline.
Not all of them are out of the box. The Hyvä ecosystem has grown significantly since 2021, and the majority of popular Magento extensions now have official Hyvä compatibility modules. Some less common or highly customised extensions still need work to function within the Hyvä framework. Our pre-migration audit identifies exactly which of your extensions fall into each category and what the resolution looks like for each one.
A properly built Hyvä theme should achieve a Lighthouse score of 90 or above on mobile for standard store pages. Many of our builds achieve scores of 95 and above on product and category pages. The qualification is that the backend also needs to be well-configured — Hyvä dramatically improves the frontend performance picture, but a slow server response or unoptimised database will still cap what the frontend can achieve. We assess both when we take on a Hyvä project.
Yes. KiwiCommerce holds official Hyvä Bronze Partner status, awarded by Hyvä.io. The partner tiers are based on verified delivery experience with the framework, not self-declared expertise. As one of a small number of official Hyvä partner agencies in the UK, we are well-placed to advise on whether Hyvä is right for your store and to build it correctly if it is.
Yes. We offer retainer-based support for Hyvä stores covering ongoing maintenance, framework updates, extension compatibility checks, and new feature development.
