Stack selection is one of the most consequential decisions a development team makes — and one of the most frequently over-complicated. Every year the landscape shifts slightly, but the underlying decision framework for European commercial software remains remarkably stable.

Here is how to think about the React vs. .NET question in 2025, without the hype.

First, a Clarification

React and .NET are not alternatives — they operate at different layers. React is a JavaScript library for building user interfaces. .NET is a cross-platform development framework for building backends, APIs, and services. Most modern applications use both.

The real questions are:

  • Frontend: React, Vue, Angular, or something else?
  • Backend: .NET, Node.js, Python, Java, or Go?
  • Full-stack: What is the right pairing for your context?

React in 2025

React remains the dominant frontend library in European commercial development. Its advantages:

  • Largest talent pool among JavaScript frameworks in the Netherlands and EU
  • Mature ecosystem (Next.js, React Query, Radix UI, Tailwind CSS)
  • Strong corporate backing with stable API evolution
  • Excellent tooling for both SPA and server-side rendering

React’s disadvantages are real: JSX has a learning curve, state management choices can be overwhelming, and the ecosystem moves fast enough that senior React developers need to actively maintain their skills.

React is the right choice when you need a rich, interactive user interface; you want access to the widest talent pool; or you’re building a product where frontend velocity is the primary constraint.

.NET in 2025

.NET 8 and 9 have continued the framework’s transformation into a genuinely modern, cross-platform runtime. Its advantages:

  • Excellent performance, consistently near the top of independent benchmarks
  • Strong typing throughout the stack reduces runtime errors
  • First-class support for microservices, gRPC, and messaging architectures
  • Deeply familiar to the large enterprise market in the Netherlands
  • Strong GDPR tooling within the Microsoft/Azure ecosystem

.NET is the right choice when you’re building for enterprise clients with existing Microsoft infrastructure; you need high-performance backend services; or you’re in a regulated industry where the Microsoft compliance story matters.

The Common Pairing

For most 3Bird clients, the optimal pairing in 2025 is React (frontend) + .NET (backend API), deployed on Azure or AWS. This combination:

  • Maximises talent availability across Europe
  • Provides strong typing on both sides (TypeScript + C#)
  • Fits the Microsoft ecosystem that most Dutch enterprises already use
  • Has excellent tooling for testing, CI/CD, and compliance

For startups optimising for speed and a smaller initial team, React + Node.js (TypeScript throughout) remains a strong alternative — particularly for teams that want to share code between frontend and backend.

When Stack Doesn’t Matter as Much as You Think

For most MVPs and early-stage products, the stack is less important than the team’s familiarity with it. A team that knows Django deeply will outship a team learning .NET at speed. If you have strong existing expertise, lean into it.

At 3Bird, our recommendations are always contextual. We have deep expertise in React, .NET, Node.js, and Python — and we’ll be honest with you when the answer is “it doesn’t really matter, pick one and move.” The best stack is the one your team can execute on today, with a clear path to scaling it tomorrow.
