A startup rewrote their backend from Python/Django to Node.js just one week after launch due to difficulties with Python’s async programming. They found Node’s event loop model much easier to work with and gained significant performance improvements.

Why it matters: Early backend tech choices affect scalability, maintainability, and developer productivity, even before a large user base emerges.

The big picture: Python async support is still evolving and can be complex, while JavaScript’s event loop is mature and straightforward for async tasks.

Stunning stat: Switching to Node.js resulted in approximately 3x throughput improvement immediately, with expectations for greater gains over time.

Commenters say: Many agree that using familiar tools matters most for startups; some criticize the initial choice of Django over FastAPI and debate async readiness in Python.
