FastAPI vs NestJS vs Spring Boot in 2026: I Built the Same API Service in All Three — Raw Truth…
📰 Medium · Python
Compare the performance of FastAPI, NestJS, and Spring Boot by building the same API service in each framework
Action Steps
- Build a simple API service using FastAPI to understand its performance capabilities
- Create the same API service using NestJS and compare the development speed and maintenance requirements
- Develop the identical API service using Spring Boot to evaluate its performance under heavy load (10k RPS)
- Configure and test each framework to measure their performance and identify potential bottlenecks
- Compare the performance data and development speed of all three frameworks to determine the best choice for a specific project
