Dunno. It’s really good with Preact + Tailwind. And I have to say that I think most problems can be solved this way and don’t require a special one-of-a-kind UI. In fact, the fewer special UIs I see, the better. I prefer standardized patterns unless they truly don’t fit a domain.
My first instinct reading an article (especially one about LLMs) is to scroll down to see the structure..

Anyway.

Do people get the impression that LLMs are worse at frontend than not? I'd think it's same with other LLM uses: you benefit from having a good understanding of what you're trying to do; and it's probably decent for making a prototype quickly.

Who says it sucks at front end? Unlike Stackoverflow, AI does a great job of "center a div." I tend to like working from reference documentation which is great for Python and Java but challenging for CSS where you have to navigate roughly 50 documents that relate to each other in complex ways to find answers.

Like I don't give it 100% responsibility for front end tasks but I feel like working together with AI I feel like I am really in control of CSS in a way I haven't been before. If I am using something like MUI it also tends to do really good at answering questions and making layouts.

Thing is, I don't treat AI as an army of 20 slaves will get "shit" done while I sleep but rather as a coding buddy. I very much anthropomorphize it with lots of "thank you" and "that's great!" and "does this make sense?", "do you have any questions for me?" and "how would you go about that?" and if makes me a prototype of something I will ask pointed questions about how it works, ask it to change things, change the code manually a bit to make it my own, and frequently open up a library like MUI in another IDE window and ask Junie "how do i?" and "how does it work when I set prop B?"

It doesn't 10x my speed and I think the main dividend from using it for me is quality, not compressed schedule, because I will use the speed to do more experiments and get to the bottom of things. Another benefit is that it helps me manage my emotional energy, like in the morning it might be hard for me to get started and a few low-effort spikes are great to warm me up.

This is something that talk with some friends, How IA is doing things in front end is complelty different from Humans. Humans can select colors and themes based in their criteria, and IA only generate what they learn as a machine that they are, and It's not bad, but the thing is that people that use IA for develop front-end are adapting what IA generate, and in the other hand developer is adapting to client. Which are different approaches.
If you are really good at something, you'll find AI sucks at everything.
This doesn't make sense. I think you mean "If you are really good at something, you'll find AI might not be as good as the something you are really good at"
I think they mean knowing that AI only looks to be good at something pulls back the curtain in a sense and afterwards all appearances of AI seeming good at something seem fake.
> If you are really good at something, you'll find AI sucks at everything.

I think it's the other way around. AI amplifies your software development skills. If you suck at software development, AI will follow your prompts and feedback and of course it will output an unmaintainable mess that barely works.

Here we are, listening to people who can barely put together a working website complaining that AI can barely put together a working website.

Corollary: if you are bad at everything, you’ll find AI to be the greatest invention in the history of mankind
I’ve had the opposite experience.

At the things I’m good at, AI is a huge boon. At the things I’m bad at, AI has little to offer.

For me, for Frontend, AI is great, because I know exactly what to do, so it’s very easy to talk it into doing it for me. I know what the problem is, I know what the solution is, and I have the language to communicate both. All that’s left is the trivialities of the implementation, I’ve already done all the hard work in my head.

Kimi k2.5 has been so far the best model for frontend. At least from my experience so far
Humm... better than Opus 4.6 or 5.4?

What are you using for the frontend? React component libraries?

If AI really sucked at front end I'd have a job right now.
If management could tell the difference between a good product and some fragile slop they wouldn't be in management, they would have a productive job.
If the economy wasn't completely broken you'd have a job right now.
If we had annual reverse hunger games the economy wouldn't be broken
In general, AI is not replacing developers yet. It's a convenient excuse to fire people for other reasons, and to pay lower wages.
I suspect the problem either lies with you or the company you worked at, because AI absolutely sucks at frontend development.

Sure, but most companies don't seem to value Front End
After years of writing native code for mobile apps I'm using Flutter, and finding that, if you do things step-wise, and check in intermediate results so you can easily roll back failed experiments, agent-assisted coding can accelerate your front end coding substantially, and you can deliver more polished results instead of obviously demo grade visual results that need refinement. And that makes it easier to communicate with your non-coder colleagues.
Except... it doesn't
Imo front end is what it’s best at.
It really is, especially with frameworks. The author post reeks of feeling threatened by AI encroaching on his job, especially with the weird AI digs
Damn, if this is the best AI has to offer, then I pity all the AI enthusiasts out there. They’re gonna have a rough waking up once this bubble bursts.

Ai ain't gonna perform at level of top front end designer but you will get you halfway at significantly less cost.
Exactly, it will do a decent job with designs using an established component library or design system. For most/many sites and web apps it will be better and faster than trying to design from scratch. There will continue to be a place for highly custom, unique designs but most smaller sites don't need to start there.
Decent? No. It’ll do a job.

Decent still way too high a compliment for such slop.

AI is a floor raiser, not a ceiling raiser
It’ll get you a generic template you could’ve gotten from any website builder out there with roughly the same amount of effort. That is not “halfway” in the slightest. That’s getting your foot on the door. Quite literally the absolute bare minimum.
Site has been slashdotted
...Does AI suck at front-end? This is news to me.
double down on betting your career on being a css expert? what could go wrong
AI is much better at front-end than me, it has really enabled me to build visual apps as a normally backend/ML guy.
Ngl I’m reading this article after having used ai to build a beautiful front end that is pixel perfect.

Yes ai can’t see, it only understands numbers. So tell it to use image magick to compare the screenshot to the actual mockup, tell it to get less than 5% difference and don’t use more than 20% blur. Thank me later.

I built a whole website in like 2 days with this technique.

Everyone seems to have trouble telling ai how to check its work and that’s the real problem imho.

Truly if you took the best dev in the world and had them write 1000 lines of code without stopping to check the result they would also get it wrong. And the machine is only made in a likeness of our image.

PS. You think Christian god was also pissed at how much we lie? :)

> Ngl I’m reading this article after having used ai to build a beautiful front end that is pixel perfect.

Was about to say the same thing

What’s the point in saying you built something beautiful and not showing it?

Share it. I used Claude earlier to test out its design capabilities and what I got as output was flat and tasteless.

It's kind of wild in terms of how it will use different random designs, even given a specific style guideline. Even if you tell it to use a given framework like MUI or Mantine, it will stray largely from format.

I don't mind working through a lot of the UI myself, but it's definitely a shortcoming IMO... that said, being able to scaffold boilerplate or testing harnesses for for complex UI has been really nice overall. I came up with the following component as an image zoom component, where I can separately control the zoom in/out in under a couple hours... took longer to setup the CI/CD stuff than the primary component logic.

Eh, for many reasons I am not posting it here. It is a passion project for something and would lead to problems if I post it here. That being said I was trying to share the technique.

The reason for the post is that even without the actual website one should be able to envision the technique and how it may or may not work. Also if you look above recently I added links to the Claude.md for another thing I was working on for a friend that also had to solve this problem.

Just want to give people the tools to use ai well from my own findings

Please share what you created! I think people have very different views for what is a good interface, or a tolerable one. I think as a front-end developer and designer I notice a lot of problems most people don't care about.
Hey, one thing I made with this technique is hartwork.life a simple Wordpress store for a friend. I used open ai to design it for me, and then used the techniques above to get Claude code to implement the proper designs.

I am still trying to learn how to wrangle Claude properly, but I have this Claude.md[1] for that I used to make the website. In particular one of the last rules about using imageMagick for comparison.

I haven’t touched this website in a bit (waiting on client) so now I use playwright mcp for the screenshots and the browser interactions.

We built the frontend for https://brooked.io and https://app.brooked.io using only prompting so I agree!

  > Your data,
  > irectl in you
  > spreadsheets
I'm guessing the third word is "directly“? The D is cut off. And the grammar is wrong, should be "in your spreadsheets" - maybe that is another letter cut off?

Go back to human devs.

You could argue that what you built isn't novel or complex in any way -- (politely) it's basically a clone of hundreds of other SAAS homepages. i.e. its a perfect use-case for AI.

Perhaps the results would be different if you had a specific novel design or interaction in mind, and you wanted the AI to implement that exactly as you wanted.

edit: My point proven by the other examples from this thread. Same format, same "feature cards" etc. https://bridge.ritza.co/ https://poolometer.com/

It shows.

The landing page looks like every other AI slopped product page out there.

I am a backend guy, so forgive my ignorance, but for web based apps I am confused what "pixel perfect" even means. I can build a site to look one way on my computer, it will most likely not look the same way on whatever device you use to access the site.

Feeding the model images for my local computer sounds like a recipe given my experience with the tools to have it over-optimize for the wrong end device.

> Yes ai can’t see, it only understands numbers.

I've also used AI to build frontends that I'm more than satisfied with, and I think it can "see" perfectly fine. The frontier models are multi-modal and pretty good at vision. You can hook up your coding harness to your browser which will take screenshots of your rendered frontend and modify the code accordingly.

I'm a backend dev and I'm always hearing about how LLMs are dramatically better at frontend because of much more available training data etc. Maybe my perspective isn't as skewed as I've been led to believe and LLMs need close supervision and rework of their output there too.
Design is an interesting beast.

Good design is not always logical. Color theory, if followed, results in pretty bad experiences. And interestingly, good design can't always be explained in a natural language.

Main thing is, it's very hard to get AI to have taste, because taste is not always statistically explainable.

The best I've gotten to is have it use something like ShadCN (or another well document package that's part of it's training) and make sure that it does two things, only runs the commands to create components, and does not change any stock components or introduce any Tailwind classes for colors and such. Also make it ensure that it maintains the global CSS.

This doesn't make the design look much better than what it is out of the box, but it doesn't turn it into something terrible. If left unprompted on these things, it lands up with mixing fonts that it has absolutely no idea if they look good or not, bringing serif fonts into body text, mixing and matching colors which would have looked really, really good in 2005. But just don't work any more.

Does this website run at 10fps for anyone else? I'm on a mac M4 w/ safari. Really doesn't help the author's point.
