Ask HN: Best toolkit to build any web or mobile app (for developers)

I was debating with a friend about the benefits of no-code versus code tools.

We're both devs, and we were arguing about the best, fastest way to build a good web app.

There are clear best choices for no-code tools (e.g. shopify for e-commerce).

But are there equally obvious choices for web apps that still require devs?

If helpful, my personal goals when building a web app are speed, quality, and flexibility.

Speed: how quickly can I go from design to shipped app.

Quality: can a new developer quickly onboard and understand the code and how to contribute.

Flexibility: I don't want to be limited in what we can do. This should be a solution that can work for (most) any kind of web app.

I think my default would be Frontend: React; Backend: Google cloud functions; Data: Firestore; Infra: Firebase

But tbh it still takes much longer / more effort to spin up a web app with moderate functionality than it does to create a shopify store.

Maybe these aren't the best / most up to date tools. I'd love to hear what other people think is best.
