Node.js development services
A Node.js development company with 14+ years in custom software, 70% senior engineers, and ISO 27001 certification. We pair a React front end with a Node backend, so one team owns the whole product.
Our Node.js development services
Match your need to a service below. APIs, microservices, and real-time systems are the core of what we build in Node.
Custom web app development
Server-side web applications on Node and TypeScript, from a first MVP to a production system serving steady traffic.
Mobile backend development
The Node backend behind iOS and Android apps: authentication, data sync, push, and the APIs your mobile Client calls.
IoT development
Devices, gateways, and dashboards connected over Node’s event-driven runtime, moving sensor data in real time at scale.
API development and integration
REST and GraphQL APIs that wire your product to payment, CRM, ERP, and third-party services.
Super app development
Multi-service platforms where payments, messaging, and bookings run side by side on one Node backend.
Enterprise software development
Enterprise systems with role-based access, audit trails, and the integrations a large organization already runs on.
Microservices development
We split a system into independent Node services that scale, deploy, and fail on their own, so one bottleneck never stops the product.
Plugin and module development
Node modules and plugins that extend your existing platform without a rewrite.
Migration to Node.js
We move legacy backends to Node and TypeScript in stages, keeping the live system running while we cut over service by service.
Maintenance and support
Ongoing care for an existing Node application: dependency upgrades, performance work, security patches, and on-call support.
Node.js consulting
We review your architecture, stack, and roadmap, then tell you where Node fits and where it does not.
Dedicated development team
A Node team of business analysts, developers, and QA that works as an extension of your in-house staff.
Powerful Node.js solutions we build
These are the application types Node is genuinely built for. Real-time, streaming, and high-concurrency work is Node’s honest sweet spot.
Complex single-page applications
Data-heavy SPAs with a Node backend serving a React or Angular front end from one JavaScript codebase.
IoT applications
Device fleets and dashboards that ingest and react to sensor data as it arrives.
Real-time collaboration tools
Shared editors, whiteboards, and workspaces where many users act on the same data at once.
Streaming applications

Modern Node in 2026
Node in 2026 is not the Node of 2019. We pick Node when these strengths match the product:
Non-blocking I/O and concurrency
One Node process handles thousands of simultaneous connections without a thread per request, which is why it fits real-time and high-traffic APIs.
npm ecosystem
The largest package registry in software means most building blocks already exist, so we build features instead of plumbing.
V8 performance
Node runs on Google’s V8 engine, the same one that powers Chrome, so compute-bound request handling stays fast without you paying for extra servers to keep up.
Scalability and microservices
Node’s lightweight runtime makes it cheap to run many small services and scale the busy ones independently.
Full-stack JavaScript
One language across the React front end and the Node backend lets a single team own the product and share code between layers.
MVP speed
A rich ecosystem and one shared language get a working product in front of users faster, which matters most for startups.
Node.js: the engine behind AI products
Where the model thinks, and the front end shows it, Node runs it.
Node.js is the engine behind AI products. It calls the models, streams responses token by token (its non-blocking I/O is built for exactly this), runs retrieval (RAG) and tool-calling, hosts autonomous agents, and exposes your tools as MCP servers, all in the same TypeScript as your front end. In 2026, TypeScript passed Python in usage, and the JavaScript AI stack is production-ready. You no longer need a separate Python service for application-layer AI.
We build with the Vercel AI SDK, the leading TypeScript AI toolkit, with one provider-agnostic interface across OpenAI, Anthropic, and Gemini; its Core runs server-side on Node. We use LangChain.js for orchestration and RAG, and Mastra for production agents and workflows, wired to whichever models you run. React renders the AI experience and Node runs it, which together make a full-stack JavaScript AI product.
The probabilistic parts, agents, retrieval, and tool-calling are governed by our Agentic Development Lifecycle (ADLC), including evaluation and tool-execution approval. The AI engine ships as a governed product you can run in production.

When to choose Node
We pick the right tool, not the one we sell. Node is the right call for I/O-bound, real-time, and full-stack JavaScript products, and now for AI application backends. For CPU-heavy work, we will tell you when Go fits better; for ML training, Python.
| Choose | When it fits | Notes |
|---|---|---|
Node.js |
I/O-bound APIs, real-time (chat, streaming, collaboration), microservices, full-stack JS, AI app backends |
Largest package ecosystem; same language as a React front end |
Go |
CPU-bound or very high-concurrency systems infrastructure, low-latency services |
Compiled performance; Node’s honest weak spot is CPU-heavy work |
Python |
Data science, ML training, heavy numerical and scientific work |
For app-layer AI (agents, RAG, streaming), Node and TypeScript are now fully viable |
Deno / Bun |
Greenfield needs security-by-default (Deno) or fast cold starts and maximum performance (Bun) |
Web-standard APIs and transferable skills; Node stays the enterprise default for ecosystem and LTS |
Tech stack we’ve mastered

Advanced tech we use with Node
Node also anchors the adjacent capabilities we build alongside core backend work.
IoT development
Node handles real-time data, device connectivity, and thousands of concurrent connections for IoT ecosystems: smart cities, industrial automation, healthcare monitoring, fleet management, and predictive maintenance.
AI development
We build AI features on the JavaScript and TypeScript stack: Vercel AI SDK, LangChain.js, and Mastra, running on the same Node backend that serves your product. The AI engine section above covers how we ship AI on Node under the ADLC governance lifecycle.
Big data development
For large-scale data streams, Node drives data engineering, analytics, and dashboards: charts and graphs that make the numbers readable.

FAQ
Is Node.js good for web development?
Yes. Node.js is a strong fit for web backends that handle many simultaneous connections, real-time features, and API-heavy products. Its non-blocking runtime makes it efficient for I/O-bound work, which covers most web applications.
How much does a Node.js project cost?
A Node.js project typically runs from $10K to $50K and up, depending on complexity. A small MVP or integration sits at the low end; an enterprise platform with microservices or an AI backend sits above $50K.
What are the benefits of outsourcing Node.js development?
Outsourcing gives you a senior Node team without the time and cost of hiring one. You get business analysis, development, and QA from one vendor, and you scale the team up or down as the roadmap changes.
Do you provide post-launch maintenance?
Yes. We keep the application healthy after launch: dependency upgrades, performance tuning, security patches, and on-call support, on a maintenance agreement sized to your product.
Is Node.js faster than other frameworks?
For I/O-bound work, Node is among the fastest options because its event-driven runtime handles many connections without blocking. For CPU-heavy work, a compiled language like Go can be faster.
