Poland's Top Node.js developers: a comprehensive review - March 2025

Introduction

Node.js dominates backend development with its speed, scalability, and real-time capabilities. NestJS builds on this, adding structure and maintainability for large-scale applications. As demand grows, top Node.js development firms are shaping the industry - here’s a look at the best in Poland in Mar 2025.

Node.js - Quick intro

Node.js is currently a trendy technology for backend development, being quick, scalable, and effective in handling real-time applications. Built on Chrome's V8 engine, it takes JavaScript out of the browser and is an ideal option for both startups and large business. Its event-driven, non-blocking design enables developers to handle multiple requests simultaneously without performance loss—perfect for those apps that must be refreshed in real time, such as live dashboards, webapps or chats.

What's the one of its strongest suits? One programming language. With JavaScript (or TypeScript), developers are able to write the entire stack, reducing context switching and making development easier. Package management is also an important strength—Node.js comes with npm, a massive repository of libraries that makes development faster and reduces boilerplate code writing. Deploying on Linux, macOS, or Windows, Node.js works flawlessly on all platforms. It's well-suited to microservices, APIs, and cloud-native web applications as well, with simple scaling as traffic goes up. Node.js has served as a consistent, high-performing solution for modern web development from small projects to large-scale enterprise architectures.

NestJS - a Node.js framework

NestJS places all the great things about Node.js and then layers on top structure, scalability, and a developer-friendly experience. It's written in TypeScript by default, and it encourages maintainable, type-safe code—something that reaps rewards on big applications. But the real secret to its success is how it's structured. Instead of a confusing heap of files, Nest.js maintains a tidy, organized layout with reusable, testable modules so that it's easier to scale as your project expands.

And yet another feature set highlight? Dependency injection. Unlike with traditional Express apps in which dependencies can get out of control, NestJS has an out-of-the-box DI system which keeps things cleaner for testing and making apps more scalable. And when it's time to build APIs, Nest has top-notch GraphQL and WebSocket support, making real-time data a breeze to work with. Under the hood, it has Express as the default but can easily be promoted to Fastify via a simple config toggle. Its native CLI is another massive win—scaffolding new services, modules, and components happens in the blink of an eye. Leaning on a rock-solid ecosystem and growing pool of users, NestJS is more than a framework; it's a full-fledged toolkit for building modern, enterprise-grade applications with Node.js.

Node.js & NestJS adoption and market share

Node.js remains a powerhouse in backend development, with its adoption showing no signs of slowing down. Back in 2018, it held just over 1% of the market, but by 2021, that number had surged past 4%, reflecting its widespread adoption across startups and enterprises alike. By 2025, while exact figures are still unfolding, the trend is clear—Node.js is everywhere. Over 30 million websites rely on it, and nearly half of backend developers use it for enterprise applications. The reasons? Speed, scalability, and efficiency. Companies like Netflix, PayPal, and Amazon trust Node.js to handle millions of requests with minimal overhead. And with projected downloads reaching 1.5 billion, its growth is steady and undeniable.

Alongside Node.js, NestJS is carving out its own space, rapidly gaining traction among developers who want structure, scalability, and TypeScript support. Built on Node.js, it takes backend application development to another level with a modular architecture, dependency injection, and built-in support for GraphQL and WebSockets. With over 47,000 GitHub stars and a thriving community, NestJS is becoming the go-to framework for building large-scale applications that demand maintainability and performance. As backend development evolves, Node.js continues to dominate, while NestJS is quickly becoming a top choice for those who want more than just raw performance—scalability, maintainability, and a well-defined structure.
