In 2025, which technology—Node.js or Python—is better for scalable backend development?

Evaluates concurrency, throughput, and suitability for real-time versus data-heavy workloads.

• Node.js scales excellently in real-time environments—handling ~90K requests/sec with ~31 ms latency using V8 and non-blocking I/O. • Python excels in AI/ML, analytics, and rapid prototyping with frameworks like FastAPI, Django—especially when combined with async capabilities and JIT compilers. Future architectures often use both—Node.js for live API layers, Python for analytics and prediction models. Tags: nodejs, python, backend, performance, scalability, real-time
