React development that scales with your ambition.
We're a React-focused development agency based in Sweden. TypeScript-first, component-driven, built for teams that care about code quality as much as shipping speed.
The ecosystem matters as much as the framework.
React isn't just a UI library — it's the foundation of an ecosystem that includes Next.js, React Native, and thousands of battle-tested libraries. Here's why we build with it.
Component-driven architecture
Every UI element is a reusable, testable component. This means faster development, fewer bugs, and a codebase that grows without becoming chaotic. New features build on existing components, not from scratch.
TypeScript-first development
We write every React project in TypeScript. Type safety catches bugs at compile time, makes refactoring confident, and serves as living documentation for your team. No more runtime surprises.
Server & client rendering
React 19 and React Server Components let us render on the server for speed and SEO, then hydrate on the client for interactivity. You get the best of both worlds — fast initial loads and rich interactions.
Massive talent pool
React is the most widely-used frontend framework. When you build with React, you're never locked into a niche — any competent frontend developer can contribute to your codebase.
React applications for every layer of your business.
From customer-facing products to internal tools, we build React applications that solve real problems across your organization.
Web applications
Full-featured web apps with authentication, real-time updates, and complex state management.
Design systems
Reusable component libraries that enforce consistency across your products and speed up development.
Dashboard & analytics
Data-heavy interfaces with charts, tables, filters, and real-time data visualization.
E-commerce frontends
Custom storefronts with cart management, checkout flows, and headless CMS integrations.
Form-heavy applications
Multi-step forms, validation, file uploads, and complex input workflows with excellent UX.
Migrations & rewrites
Incremental migration from jQuery, Angular, or Vue to React — without disrupting your users.
The best React code is the code your next developer can understand in five minutes. We optimize for clarity, not cleverness.

Modern tools, proven at scale.
We pair React with a focused set of tools we know deeply. Every library in our stack is chosen for reliability, not hype.
TypeScript
Every project, every file. Type safety from component props to API responses.
Next.js
Our default React framework. App Router, Server Components, and built-in optimization.
Tailwind CSS
Utility-first styling that keeps our components self-contained and consistent.
React Query / SWR
Server state management with caching, background refetching, and optimistic updates.
Zustand / Jotai
Lightweight client state when React's built-in state isn't enough. No Redux boilerplate.
Vitest & Playwright
Unit tests for logic, integration tests for components, E2E tests for critical flows.
React projects by the numbers.
Real metrics from our React development work across client projects.
React components in our shared design system.
TypeScript coverage across all projects.
Time to interactive on average page load.
React Development FAQ
Common questions about hiring React developers.
For most web applications, we recommend Next.js — it's React with server-side rendering, routing, and optimization built in. If you're building a single-page app or a widget that embeds in another site, plain React with Vite may be a better fit. We can advise based on your specific needs.
Absolutely. We regularly join existing projects — adding features, fixing performance issues, or refactoring legacy code. We start with a code audit to understand the current state and create a prioritized improvement plan.
Our focus is web applications. For mobile, we recommend React Native specialists. That said, we design our React web apps to be fully responsive and PWA-ready, which covers many mobile use cases without a native app.
TypeScript for type safety, ESLint and Prettier for consistency, Vitest for unit tests, Playwright for E2E tests, and code review on every pull request. We also set up CI/CD pipelines that run all checks automatically before any code reaches production.
