European TypeScript development companies cover everything from React and Next.js interfaces to Node.js backends, SaaS products, enterprise platforms, and JavaScript modernization. The companies below differ in technical focus, delivery model, and project scale, so the numbering is primarily used to structure the comparison rather than represent an absolute performance ranking.
Gilzor develops custom web products with TypeScript used across both frontend and backend work. Its frontend stack includes TypeScript, React, Next.js, Redux, HTML, CSS, and Tailwind, while backend projects can use TypeScript with Node.js, NestJS, Express, TypeORM, and Sequelize. This gives the team the ability to keep TypeScript within a product from the interface through server-side logic.
The wider delivery process also covers business analysis, UX/UI, QA, infrastructure, and post-launch support. Gilzor has European offices in Warsaw and Limassol.
SysGears has a dedicated TypeScript development practice covering consulting, custom applications, frontend and backend engineering, mobile development, and JavaScript-to-TypeScript migration. Its stack combines TypeScript with React, Next.js, Node.js, Express, and NestJS, while supporting tools include GraphQL, Prisma, TypeORM, Jest, Playwright, and Cypress.

A-listware combines custom software development with dedicated teams and engineering outsourcing. TypeScript is explicitly included among the technologies supported by the company, together with Node.js and other backend and frontend technologies.
This delivery model is particularly relevant when a company already has its own product organization but needs additional developers for an existing TypeScript codebase. A-listware also provides broader software services for web portals, ecommerce products, collaboration systems, analytics solutions, and enterprise applications. The company maintains a UK office in St. Leonards-On-Sea.
The Software House is a Polish software development company with substantial JavaScript and TypeScript experience. Its engineering team has described TypeScript as one of its key technologies and uses it across React frontend development and Node.js backend projects. The company also maintains its own TypeScript and Node.js tooling for software projects.
Its current service portfolio includes web development, modernization, cloud engineering, product design, mobile development, and dedicated engineering teams. This makes The Software House relevant to established products where TypeScript development needs to be combined with architecture, cloud, or long-term modernization work.
OSKI Solutions provides dedicated TypeScript development across React, Angular, Vue.js, Next.js, Node.js, and NestJS environments. Its TypeScript work includes type-safe frontend development, Node.js backends, shared API contracts, and incremental migration of existing JavaScript applications.
The company also covers the surrounding engineering requirements, including custom software, application development, cloud infrastructure, DevOps, integrations, and dedicated teams. OSKI operates from Tallinn and can support projects ranging from focused TypeScript modernization to full-stack applications where frontend and backend types need to remain aligned.
EL Passion develops web applications with TypeScript in Node.js, particularly with NestJS on the backend and React or Next.js on the frontend. Current engineering roles at the company explicitly require developers to work with this TypeScript-based full-stack combination.
Its portfolio also provides direct examples of TypeScript in production work. One published project used TypeScript with Express to add type safety to a business-critical ecommerce platform, while another combines React, TypeScript, Node.js, and Next.js. EL Passion is based in Warsaw and works with businesses across Europe and other international markets.
Apiko has a dedicated TypeScript development offering for full-cycle applications, enterprise platforms, frontend systems, backend services, and JavaScript migration. The company works across the full stack, with React or Angular available for interfaces and Node.js for backend development.
Its TypeScript practice also covers architecture, automated testing, QA, and post-launch development. A published enterprise case describes TypeScript being used across a multi-module manufacturing management platform, giving buyers evidence of the language being applied beyond smaller frontend projects. Apiko maintains a European office in Tallinn.
Scalo provides a dedicated TypeScript development service for web and mobile applications. The company's stack includes TypeScript with React, Angular, or Vue.js on the frontend and Node.js with NestJS or Express on the backend. It also supports JavaScript-to-TypeScript migration and the modernization of growing codebases.
Scalo can provide individual engineers, development teams, or broader outsourced software delivery. Its European footprint is substantial, with offices in Wrocław, Warsaw, Kraków, Katowice, Gdańsk, and Berlin, making it relevant for businesses looking for a development partner with multiple locations in the region.

SoftPro is a Warsaw-based custom software company working across React, Node.js, .NET, Azure, cloud development, and business applications. Its current public service pages emphasize modern JavaScript web stacks alongside Microsoft technologies, including frontend work with React and backend development with Node.js.
net-devs works on enterprise software, cloud platforms, AI engineering, modernization, and modern frontend systems. Its frontend practice explicitly combines TypeScript with React, Angular, and Vue, while backend projects can use Node.js, .NET, JVM technologies, Python, and Go.
The company positions TypeScript within a wider engineering process rather than as an isolated service. Testing, architecture, cloud deployment, and continued product evolution are part of that model. This makes net-devs particularly relevant for organizations modernizing enterprise interfaces or extending an established engineering environment with TypeScript developers.
Itexus develops financial and fintech software, with TypeScript included in its enterprise technology stack and project portfolio. Its current technology guidance lists TypeScript as an option for backend APIs, business logic, and microservice architectures, while its portfolio includes NestJS and TypeScript alongside React, .NET, Azure, and other technologies.
For financial companies, the main advantage is the ability to combine TypeScript development with banking, lending, trading, wealth management, and other domain-specific engineering. Itexus is headquartered in the United States but maintains a development office in Warsaw, giving it a direct European presence.
Monterail is closely associated with the Vue.js and Nuxt ecosystem, making it particularly relevant when TypeScript is being used in Vue-based applications. The company is an official Vue.js partner and has also become a Nuxt partner. Its current technical materials cover TypeScript integration for Vue and Nuxt applications, including type-safe client and server-side development.
Monterail supports new product development, web applications, MVPs, and Vue or Nuxt migrations. This focus makes it a more specialized option for TypeScript projects centered on Vue architecture rather than a framework-independent TypeScript consultancy.
STX Next uses TypeScript across both frontend and backend engineering. Its current technology stack describes React with TypeScript as the default web stack for complex interfaces, SaaS products, dashboards, and internal tools. On the backend, it combines Node.js and TypeScript with NestJS, Express, Fastify, tRPC, Prisma, and related tools.

TypeScript sits within a broader engineering portfolio that also includes Haskell, Rust, Python, Elixir, and Nix.
This wider technology mix makes Serokell relevant when TypeScript is one component of a technically diverse product rather than the only language involved. The company has European locations in Tallinn and Paris and also uses TypeScript within its financial software development work.
Mobian is a European software development studio registered in Estonia, with engineers in Ukraine and clients across Europe and North America. The company works on custom digital products, team augmentation, mobile applications, SaaS platforms, and full-cycle software development for industries such as healthcare, fintech, logistics, and telecommunications.
Its web development work includes React applications, while its technical resources also cover TypeScript-based React development with Vite. TypeScript is not presented as a separate commercial service on Mobian's current website, so the company is better considered for projects where TypeScript forms part of a wider React or full-stack development requirement.
The TypeScript development companies in Europe covered in this list offer different approaches, from focused frontend and backend development to full product delivery, modernization, and dedicated engineering teams. The right fit depends on the project itself, including the framework, existing architecture, team setup, and the level of support needed after launch.
For companies building a new web product, moving an existing JavaScript application to TypeScript, or extending an internal development team, it is worth looking beyond the technology list alone. Relevant project experience, communication processes, testing practices, and the ability to work with an existing codebase can matter just as much.
Gilzor, along with the other companies featured here, gives businesses several options for building TypeScript-based software with European development teams. Comparing their technical focus and delivery models should make it easier to narrow the list to partners that match the requirements of a specific project.
