Okay, so this is cool, but also vibecoded by someone who just does frontend. I totally support AI development, but the first commit was 4 days ago and it's entirely written by claude. The UI looks like "the style that that AI comes up with" turned into a C framework.
I don't want to discourage this kind of experimentation, but I also question how much of the last 20+ years of UI and C knowledge was not used in the construction of this project. Also, do I want to build a kanban board in C? Unsure.
Just take care when evaluating this for actual usage.

The thing with these kind of projects is that... What value do they really bring to the table? Because if it's so easy to come up with something like this (and arguably easier over time), then if I need a UI toolkit and components for my app, I can just prompt them right away to obtain something like this with minimal effort. Plus, adapted to my needs, my code, my platforms and language. UI/UX done right is still a dance between design and engineering. But I'm not sure these libraries do solve anything meaningful today that is worth the abstraction and dependency.

I am pretty sure that, even though this project is generated by AI, there will be a large majority of quicks and edge cases and bugs, just like as if a bunch of people would have written it. It's just that the initial bulk of the code was produced in a fraction of the time. All those bugs, quicks and edge-case still need to be resolved (if you were to actually use this). If you prompt your own version of this you just end up with your own set of bugs, quirks and edge-cases. The nature of software hasn't changed, just the speed with which we produce it.

That was more or less the point I was trying to make. You can vibe-code your own variant of this project (as the poster I was replying to suggested) but you run into the same problem that you need many more iterations of refinement. If we think that everyone is simply going to vibe-code their own UI frameworks (or whatever) going forward then I think that is a wrong assumption.

It has no value, and you can tell basically immediately.
People are becoming extremely lazy and shipping the first slop the model generates because they get a rush from putting their stuff in tot he world as fast as possible.
However, I would bet significant money that all the projects like this (where every aspect has hallmark slopisms (the vibe interface design, the copy) will lose out to projects that are also heavily AI coded but that took the time and care to actually polish and differentiate themselves and thus are later to the game because they shipped after a few weeks or a month of work and refinement instead of a day.
AI can save you a lot of time but it can't save you from your own lack of restraint and your inability to discern and be an objective judge of the value your thing will have to other people. For software, mere existence is no longer sufficient anymore. Anyone can generate whatever you made instantly if you put zero effort or discernment into it. This is why so many of the Ainfluencers are emphasizing "taste".
But even taste won't save you on the end either, since anyone can clone your stuff as soon as it ships.
I personally think the future of software is probably just two extremes:
1. Personal dinky vibe coded apps that all have their individual creator as the sole user.
2. Large scale apps that don't work without significant marshaling of hard physical resources (e.g. LLMs themselves).
All the middle bits, user applications that target a specific problem space but that run locally and/or don't need legions of data centers and networks to run, will probably just die eventually. Maybe a couple of established apps will stick around in business contexts because employees all using their own personal apps and workflows causes too much coordination overhead, but at the consumer level I fully except everyone will be just vibing their own stuff pretty soon here.

btown 10 hours ago [-]
Yea, there's some nuance here. If you're a senior engineer in the pre-LLM world, you're likely spending more of your time guiding a team than you are writing lines of code. Perhaps you're writing prose for code review guidelines and guardrails around architectural patterns, with trust that this is followed and propagates to the org. Perhaps you're giving guidelines that anything that implies a business-level decision needs to be escalated and have a rollout plan, not just hardcoded.
The question is: if you're doing this same thing, but with LLMs as your "reports," is it vibe coding? The term was once an epithet, but I think it's expanded to refer to the technique of not living in an IDE, not the objective function.
If your objective function places an emphasis on maintainability: vibe coding can be a positive. If not: it can be a source of great pain. As with many things, it's the wielder, not the technique.

Well, actually they do, but the LLM wouldn't know why.

LLMs are useful only for that last part, quickly comprehending a strange repo you found from 15 years ago.

There are some libraries that use native widgets on each platform, e.g. libui-ng. Although the issue with things like this is that you aren't going to be able to use all of AppKit, and you get forced into the lowest common denominator expressable by all platforms.
A good middle ground might be having platform-specific pieces but expressed using a more standard domain-specific language. E.g. technically you can already wire up GUIs without interface builder but it's quite verbose. There should be some simpler way to express layout constraints and have button callbacks.

raphlinus 15 hours ago [-]
Yes, and? As the cost of code generation approaches zero, this starts to make more sense, especially if you do have mechanisms in place to ensure safety and correctness.
I did an experiment a couple weeks ago of having Opus 5.5 translate an MP3 decoder from Rust into Cortex-M33 assembly language, both raw asm and symbolasm. The code was 3x smaller and ~1.5x faster than Rust -O3. These seem like gains that are worth it.
zamadatix 14 hours ago [-]
As the cost of code gen approaches 0 the cost of the test suite actually grows. Not just in definition, but execution.
An MP3 decoder for a single target doesn't really run into that complexity, a UI components library for (Linux, Windows, macOS) * (x86-64, ARM64) suddenly has a 6x multiplier on what was already something with waaay deeper dependencies and integrations than MP3.
At least that's what I've noticed vibing my DE without external libraries. It went really fast when the complexity was small because most of the work was in adding code. Then it started taking longer to build and test, even with optimized builds and tests, than it took for the AI to do its part.
piker 15 hours ago [-]
Yes that makes sense, but if you're iterating on software then I think C will generally win due to its ability to compile cross-platform until you want to build a "release" which you could do by having Fable translate it to ASM at that point.
genxy 15 hours ago [-]
Did you have it go directly to asm or emit the assembly from the Rust toolchain and then contract that? For small stuff, I have been having it write directly, or larger pieces I am having better results via contractions.
raphlinus 15 hours ago [-]
For this experiment I had it write directly.
I should add, part of the experiment was to test whether having variable names and (C style) types would help the LLM. For a task of this size (about 1.5 kLoC Rust, 3k insn asm) it was inconclusive, but for larger projects I suspect it would make a difference.
And the plan for symbolasm is to move past C style types into Rust style and maybe dependent typing, specifically to facilitate automated proofs.

What an odd statement. Unreadable code is unreadable regardless of language. I’ve seen my fair share of unreadable C. Indeed Rust can be ugly in advanced use cases with heavy syntax but C’s simpler syntax does not mean it is always readable either. Hell, I've seen unreadable Python and Lua!
C has in fact been displaced in many places. Just because it survives in a few holdout contexts is a historical artifact more than a testament to the language.

comex 15 hours ago [-]
I'm observing the opposite phenomenon. I recently vibecoded (with supervision) a 25k-line Rust codebase that takes 15 seconds for every build. If I were writing that by hand, a 15-second build time would drive me crazy and I would stop working until I could find a good way to speed it up. With vibecoding it barely matters, because the interval between builds is much longer and the agent (Opus 5.5) spends most of its time thinking or running tests. Unlike me, the agent rarely makes the kind of trivial mistakes that require rebuilding multiple times in a row.
Leaving memory safety up to a model is wild. That's not a sound guarantee of safety for anything.

Since most of my code for work is AI-generated now, I recently started a small side project in part to continue practicing coding by hand, and decided to use C. There's something nice about using a language that's simple enough that I could write/maintain my own compiler if I really had to.
I'm really curious how secure C software would be if reviewed by AI and run exclusively in a WASM runtime.
badsectoracula 7 hours ago [-]
So, i downloaded it, built and tried some demos. On the positive side:
1. It looks and behaves very polished. From playing around with the gallery the only issues i noticed is that the mouse wheel goes to the "outermost" control instead of the "innermost" and that there isn't a right click / context menu for text input fields with commands like copy, paste, etc (but the common shortcuts do work - including editing shortcuts like home, end, shift+movement, ctrl+d, etc).
2. According to btop the applications seem to use relatively little memory compared to other apps that look similar (~73MB). Of course it "helps" that other apps that look similar tend to use either Electron or some embedded web browser that balloons memory usage to several hundred MBs :-P.
3. There are practically no dependencies - even OpenGL seems to be an optional runtime dependence. Using objdump shows that it only depends on libm, libSM, libX11, libXext and -of course- libc. This is neat for self-contained applications.
4. The files are also relatively small - after stripping debug info from the release binaries (not sure why they're there) the hello world example is ~323KB, most examples (that use richer UIs) are somewhere between 350KB and 400KB and the gallery that contains everything is 1.4MB.
5. The UIs feel very light and snappy/responsive.
On the negative side:
1. The apps always seem to use ~4-5% CPU here - this is because they keep drawing the window all the time. Mangohud shows them not capping the FPS at all - which is good for smooth and responsive input, but drawing should stop if there are no changes to the scene/UI that need updates.
2. The code looks very messy - i do not see any `.clang-format` or anything like that. If you're going to use LLMs for writing the code IMO you should have both automatic code formatting and a `CODE_STYLE.md` (or something like that) for specifying how the code should look. It doesn't avoid the LLMisms in code but helps a lot to keep it readable (IMO at least).
3. There is no custom theme support (you can customize some aspects of its theme but you cannot make it look like, e.g, Windows 95, Mac OS X Leopard or Morrowind).
On the "it depends on your taste" side:
1. It is clearly very web and mobile inspired.
2. It uses an immediate mode approach.

dvt 15 hours ago [-]
So funny seeing these kinds of frameworks being vibe-coded. I can tell the author has never used the zillions of frameworks the LLM was trained on. Writing (and maintaining) this kind of code is absolute nightmare fuel.
There's a reason QT uses XML for their layouting, there's a reason people prefer Tauri + Vue/React, there's a reason Swift uses declarative paradigms in all their UI code. It's not that you can't build good UI frameworks in low-level languages; for example, I think Go's Fyne[1] is a pleasure to use. But people actually used their brains when designing that framework, as opposed to "hey Claude build a UI framework in C, make no mistakes."
That looks pretty readable to me. Somewhat noisier than SwiftUI due to all the repeated "cui_", but not much. I've seen far worse.
I would be more concerned about the opposite problem: the fact that it's apparently reactive and thus inherits the same performance pitfalls as every other reactive UI framework. Retained-mode UI is much uglier (at least if you build the UI in code) but doesn't have these issues.
edit: actually it's worse than reactive, it's full immediate-mode render-everything-every-frame.

I’ve also spent the last couple of weeks vibe coding a component-based UI framework for C. My target is embedded hardware with 2 * 300mhz ARM 32 CPU, and a Nintendo 3DS like OpenGL ES 1.1 GPU from DMP: Fujifilm cameras from 2013-2016 like the X70, X-E2, X-T1, X100T. It’s a bit faster than iPhone 2007 on CPU side, and slower on the GPU side due to needing to copy from GPU back to main memory for scan-out. It’s funny how these things seem to come up and then everyone’s doing it.
I didn’t see the code here because I couldn’t find an easy link to its Github. My UI framework i’m calling FocalUI. We do layout and basic geometry with a fork Clay where we added “layer” and “focusable” markers to Clay elements. Instead of drawing immediate mode, we store a list of draw commands and layer geometry in a CoreAnimation-like tree. The renderer composits the layer tree and renders to OpenGL, and we use damage tracking to copy just the changed pixels from the GPU back to the camera’s framebuffer for scan-out.
It’s been a huge effort to add touch inertial scrolling, spring animation, navigation effects etc at 55hz to this device that before only did d-pad nav at 25 Hz, but things are starting to shape up for a release this week :)

Shame to put effort into encouraging more C code. All C code needs to be torn out by the roots. I don't care how carefully crafted it is and how many Fable passes have been done, it is inherently unsafe.
I don't want to discourage this kind of experimentation, but I also question how much of the last 20+ years of UI and C knowledge was not used in the construction of this project. Also, do I want to build a kanban board in C? Unsure.

There's a thing that people who are infatuated with AI can't understand: anybody else has the same power as you! The old entrepreneurship-like ideal of trying to create something new just for the sake of innovation doesn't work anymore. Innovate on something that solves a problem you have, for you. Otherwise it's just slop, introducing chaos to system, increasing internet entropy.
We have GPUI, we have web components, we have Clay UI. No one needs another C UI library.
Well, actually they do, but the LLM wouldn't know why. You gotta have used all these to figure it out, and then spend months wondering upon a better design, researching old experiments by random people in archived repos for inspiration. LLMs are useful only for that last part, quickly comprehending a strange repo you found from 15 years ago.
In the Apple world, Native usually means using the system UI components and the Apple guidelines.
Wouldn't "native ... for C" be redundant?
A good middle ground might be having platform-specific pieces but expressed using a more standard domain-specific language. E.g. technically you can already wire up GUIs without interface builder but it's quite verbose. There should be some simpler way to express layout constraints and have button callbacks.
Or some flag to ignore users that post these types of projects often.
Though, funnily enough, this kind of info and more is extremely easy to add to HN via a vibed extension. At this point, mine just stops HN from loading completely and constructs its own page (with a proper dark theme and the information I care about).
The reason for this is an effort asymmetry: casting upvotes is easy, and most people do it without much thought, whereas determining that something is spam or misinformation requires looking a lot more closely.
It's not my project but I will definitely give the library a try.
Yes, I sometimes wish for a downvote button, but so far I have more often wished for a way to silently make flagging a no op for users that abuse it.
I did an experiment a couple weeks ago of having Opus 5.5 translate an MP3 decoder from Rust into Cortex-M33 assembly language, both raw asm and symbolasm. The code was 3x smaller and ~1.5x faster than Rust -O3. These seem like gains that are worth it.
An MP3 decoder for a single target doesn't really run into that complexity, a UI components library for (Linux, Windows, macOS) * (x86-64, ARM64) suddenly has a 6x multiplier on what was already something with waaay deeper dependencies and integrations than MP3.
At least that's what I've noticed vibing my DE without external libraries. It went really fast when the complexity was small because most of the work was in adding code. Then it started taking longer to build and test, even with optimized builds and tests, than it took for the AI to do its part.
I should add, part of the experiment was to test whether having variable names and (C style) types would help the LLM. For a task of this size (about 1.5 kLoC Rust, 3k insn asm) it was inconclusive, but for larger projects I suspect it would make a difference.
And the plan for symbolasm is to move past C style types into Rust style and maybe dependent typing, specifically to facilitate automated proofs.
C has in fact been displaced in many places. Just because it survives in a few holdout contexts is a historical artifact more than a testament to the language.
Rust with no deps and a single compilation unit is already fast.
The tools have gotten fancier, for sure, though.
For larger codebases, things might be different.
I'm really curious how secure C software would be if reviewed by AI and run exclusively in a WASM runtime.
1. It looks and behaves very polished. From playing around with the gallery the only issues i noticed is that the mouse wheel goes to the "outermost" control instead of the "innermost" and that there isn't a right click / context menu for text input fields with commands like copy, paste, etc (but the common shortcuts do work - including editing shortcuts like home, end, shift+movement, ctrl+d, etc).
2. According to btop the applications seem to use relatively little memory compared to other apps that look similar (~73MB). Of course it "helps" that other apps that look similar tend to use either Electron or some embedded web browser that balloons memory usage to several hundred MBs :-P.
3. There are practically no dependencies - even OpenGL seems to be an optional runtime dependence. Using objdump shows that it only depends on libm, libSM, libX11, libXext and -of course- libc. This is neat for self-contained applications.
4. The files are also relatively small - after stripping debug info from the release binaries (not sure why they're there) the hello world example is ~323KB, most examples (that use richer UIs) are somewhere between 350KB and 400KB and the gallery that contains everything is 1.4MB.
5. The UIs feel very light and snappy/responsive.
On the negative side:
1. The apps always seem to use ~4-5% CPU here - this is because they keep drawing the window all the time. Mangohud shows them not capping the FPS at all - which is good for smooth and responsive input, but drawing should stop if there are no changes to the scene/UI that need updates.
2. The code looks very messy - i do not see any `.clang-format` or anything like that. If you're going to use LLMs for writing the code IMO you should have both automatic code formatting and a `CODE_STYLE.md` (or something like that) for specifying how the code should look. It doesn't avoid the LLMisms in code but helps a lot to keep it readable (IMO at least).
3. There is no custom theme support (you can customize some aspects of its theme but you cannot make it look like, e.g, Windows 95, Mac OS X Leopard or Morrowind).
On the "it depends on your taste" side:
1. It is clearly very web and mobile inspired.
2. It uses an immediate mode approach.
EDIT: It's immediate mode.
Take the chips and rating as an example
https://yappologistic.github.io/CUI/#/c/chips-and-rating
It’s purely aesthetic as functionality (and ux) wise, chips are not different from checkbox with labels and rating is just a discrete slider.
And as I thought, you can see the duplicate code for switch and checkbox here.
https://github.com/yappologistic/CUI/blob/f1202e6d98cdc297f9...
People do need to differentiate between UX primitives and something that just looks different.

I would be more concerned about the opposite problem: the fact that it's apparently reactive and thus inherits the same performance pitfalls as every other reactive UI framework. Retained-mode UI is much uglier (at least if you build the UI in code) but doesn't have these issues.
edit: actually it's worse than reactive, it's full immediate-mode render-everything-every-frame.
You're on shaky ground using xml for ui layouts as posterchild for good developer ergonomics.
Sure there is, it's just that the reason might be a very bad one unlike what you imply
The use of C, in that case, was likely made for performance reasons and avoiding dependencies.
The author added dozens of complex widgets in a few days, AI driven of course. The intended audience is not manual coders, you would show some examples to the clankers and ask for you UI and custom widgets.
_sigh_
I didn’t see the code here because I couldn’t find an easy link to its Github. My UI framework i’m calling FocalUI. We do layout and basic geometry with a fork Clay where we added “layer” and “focusable” markers to Clay elements. Instead of drawing immediate mode, we store a list of draw commands and layer geometry in a CoreAnimation-like tree. The renderer composits the layer tree and renders to OpenGL, and we use damage tracking to copy just the changed pixels from the GPU back to the camera’s framebuffer for scan-out.
It’s been a huge effort to add touch inertial scrolling, spring animation, navigation effects etc at 55hz to this device that before only did d-pad nav at 25 Hz, but things are starting to shape up for a release this week :)
Well, fewer problems!
