The Frontend Stack Wars Are Over. OpenAI Just Picked a Winner.

You’ve surely heard of the GPT-5 launch in August 2025, but did you catch the part of the release where OpenAI recommended a frontend tech stack for use with ChatGPT? Here’s the scoop.

I’ve always been a realist that tech decisions are overwhelmingly made by “what the guy or gal who used to work here was most comfortable with.”

But I’ve been screwed over by type errors caused by untyped languages like JavaScript in production apps so many times I’ve lost count.

So I definitely have strong opinions as to what is the best frontend stack for building web apps, and apparently OpenAI does too.

It’s no problem at all if you missed OpenAI’s “announcement” about who won the frontend stack wars because I did the boring work of reading their entire GPT-5 prompting guide. Here’s what I found.

I Guess OpenAI Has Tribal Favorites for Stacks Too

As I was saying before, I think it’s entirely fine and preferable, in fact, to have strong opinions about your choice of technologies.
