I'm looking for a framework that allows for quick prototyping on the backend, has a low learning curve, but also doesn't compromise on performance. I have some experience with Next.js and am considering Django or Express. So, which frameworks do you prefer? Which one do you find more comfortable to develop in and why? If you share your experiences on this topic, we can all learn something.
Backend frameworks comparison: which one is more efficient?

If you're coming from Next.js, you're already used to a full-stack JavaScript environment; Express is then the most natural choice for quick prototyping. With just a few lines of code, you set up a server, manage routes, and can even integrate it with your Next front end via API routes. The learning curve is almost nonexistent if you already know JavaScript, but when it comes to purely CPU-bound performance, Express doesn’t always match more optimized solutions.
Django, on the other hand, offers a "batteries-included" ecosystem: ORM, auto-generated admin, built-in authentication, and migrations. It’s a real time-saver when your project needs a robust database or a functional admin interface right away, even if you have to accept a slightly steeper learning curve (Python + Django concepts). If you're looking for a compromise between Express’s lightweight nature and Django’s rich functionality, check out NestJS: it keeps TypeScript/Node syntax, offers a modular architecture inspired by Angular, and includes modules for validation, logging, and even an ORM (TypeORM). In practice, I’ve gone from an Express prototype in 30 minutes to a more structured NestJS project in a few hours while keeping performance close to pure Node.
In short: for an ultra-fast MVP, go with Express; for an app that needs to scale with an admin and ORM, choose Django; if you want Node’s power with a solid architecture, NestJS is a great alternative.
