Oxtren Labs – a digital studio in Kaunas
A Kaunas studio that also builds its own product.
Since 2022 we have been building websites, online stores and digital platforms for companies in Lithuania and the EU – from the first conversation to maintenance after launch. We also build our own product, the Shopify app Hesio, so we know what happens after launch.

Who it's for
A first or new website
Companies that need a first or new website and want to edit the content themselves.
Selling online
From a first store to a larger catalogue with integrations – on Shopify, WooCommerce or a custom solution.
When a website is no longer enough
You need a client portal, a system for your team or integrations between the tools you already use.
When you need someone to maintain it
Your site is already live and you're looking for someone to look after it. We take over systems built by others after a technical audit.
Core competencies
Design and development together
UI/UX design and development in one team – you approve the designs before development starts.
Next.js websites
Our main stack is Next.js with Payload CMS; alternatives are Sanity, headless WordPress or a custom CMS.
Ecommerce
We build and maintain Shopify and WooCommerce stores; for larger ones, headless WooCommerce or a custom solution. We integrate the most popular payment and delivery providers to suit the business.
Platforms and integrations
Client portals, internal systems, APIs and process automation with n8n or Make.
Technical SEO and conversion
Speed, structured data, analytics and finding what blocks the purchase journey.
Infrastructure and maintenance
Docker and Coolify, Cloudflare, Hostinger VPS servers, monitoring and daily backups.
How we work
Conversation
We clarify the goal and what you already have. For a system we take over – a technical audit.

Price, scope and timeline – in writing, before any work starts.
Build
Design and code in one team. Later you edit the content yourself.
Launch
Basic SEO, analytics and a speed check. After launch – a 6-month warranty.
