WEB DEVELOPMENT
Scalable, fast and high-converting websites built with modern technology. From Webflow to headless CMS — as a web development agency, we deliver solutions that perform.
EVERYTHING YOU NEED FOR A MODERN WEBSITE
We do not just build websites — we build digital tools that drive growth. Every project starts from your business goals and is optimised for SEO, speed and conversion from day one.
Webflow websites
Marketing websites in Webflow with a full CMS, a component library and a context file for AI-driven updates via MCP — fast publishing cycles in an editor-friendly interface your team will actually want to use.
Headless CMS
Headless architecture with Sanity or Contentful + Next.js — for companies that want to own their front end, switch CMS without rebuilding, or serve several channels from the same content.
Landing pages
Conversion-optimised landing pages designed to drive leads and sales.
E-commerce
E-commerce in Shopify or Webflow Commerce — from product catalogue and checkout flows to ongoing CRO and performance optimisation.
Maintenance
Ongoing technical maintenance, security updates and content changes — including performance monitoring so that Core Web Vitals hold up over time.
Conversion rate optimisation
Data-driven improvements to UX, copy and flows — A/B tested, measured and iterative. We find the friction where it actually sits and convert more of the visitors you already have.
FROM IDEA TO LAUNCH
Strategy & brief
We map your goals, audience and technical requirements in a kick-off meeting. The result: a clear brief and project plan.
Design & prototype
We design in Figma, using your brand guidelines as the foundation. You approve a clickable prototype before development starts.
Development
We build in Webflow or with a headless CMS, focusing on performance, accessibility and an SEO-friendly structure. Our development is AI-assisted, using Claude with an MCP connection directly to Webflow or your headless CMS — which shortens the development cycle considerably without compromising on code quality.
Testing & QA
Thorough testing of functionality, responsiveness, speed and cross-browser compatibility.
Launch
We handle DNS, hosting and deployment. You get training in how to manage the CMS, plus a maintenance plan.
TOOLS WE WORK WITH
We choose tools for what the project needs — not for what is fashionable. Every technology in our stack is chosen for performance, scalability and long-term maintainability.
CMS
Webflow
Our first-choice platform for websites driven mainly by marketing teams — visual development, a powerful CMS, fast hosting and an editor-friendly interface.
hosting
vercel
Edge hosting with a global CDN and CI/CD straight from GitHub — Next.js's production environment, where performance is the default, not an add-on.
language
Typescript
Type-safe JavaScript that catches errors before they reach production — standard in all our development projects.
CMS
Sanity
Headless CMS with structured data, real-time editing and GROQ queries — our choice when Webflow's CMS is not enough for complex content modelling.
framework
Next.js
React's production standard — server rendering, edge rendering and full SEO support. The foundation of all our headless websites and web apps.
design
figma
Collaborative design and prototyping, from concept to handoff.
animation
Gsap
The industry standard for advanced web animation — now part of Webflow after the acquisition of GreenSock. Powers scroll effects, transitions and interactive elements.
analytics
plausible
Privacy-friendly analytics without a cookie banner — GDPR-compliant out of the box, faster loading than GA4 and enough data for most marketing teams.
e-commerce
Shopify
The world's leading e-commerce platform — our choice for Swedish stores that want to grow without plugin hassle or self-hosted infrastructure. Covers everything from product catalogue and payments to stock and multichannel selling.
AI
Claude
Anthropic's LLM, which we use for AEO-ready content production, semantic chunking, design and design system documentation. We connect Claude directly to your website through an MCP server — so Claude can read, suggest and update CMS content in real time, with no manual steps in between.
THE RIGHT TOOL FOR THE RIGHT PROJECT
The choice of platform affects everything from performance and SEO to the cost of ongoing maintenance. We always recommend the option that best fits your goals.

Questions & answers
How long does a web project take?
Most projects take 4–8 weeks, depending on the scope. A simple landing page can be ready in 2 weeks, while a complex website with many integrations takes longer.
Which platforms do you build in?
We work mainly with Webflow for CMS-driven websites, and with Next.js and a headless CMS (Sanity, Contentful) for more complex builds.
How much does it cost to build a website?
It depends on the platform, the scope and how much needs to be custom-built – and the build cost is only part of what a website costs over time. Work out what your website will cost to build and own with the calculator in our guide How much does a website cost in 2026?.
Is SEO optimisation included?
Yes. All our websites are built with technical SEO as the foundation — correct HTML structure, metadata, schema markup, Core Web Vitals and fast loading times. For ongoing search engine optimisation after launch, see our SEO service.
Do you offer maintenance after launch?
Yes. We offer ongoing maintenance agreements that include security updates, content changes, performance monitoring and technical support.
Can you rebuild our existing website?
Absolutely. We carry out a technical audit of your current website and draw up a redesign plan that preserves its SEO value and improves the user experience. We explain how we preserve SEO value in a rebuild in Migrate a website without losing rankings.
