ugh this looks dated even by 2016 standards

when will developers learn UI actually matters

bootstrap was a mistake, and lowered the bar for everyone

i don't get these types of products anymore. i think they're useful in their own way, but i can literally create styles with claude/gemini in a heartbeat and not have to pay some insane fee.
I think you missed a trick not naming it Railwind UI.
I used this about a year ago when I went through a short Rails phase. I was a bit surprised not to see more Rails-specific UI libraries considering how batteries-included the rest of the framework is, and at the time I didn't really 'get' tailwind. I'm not in a Rails phase anymore, but nice work on the library!
(comment deleted)
maybe I'm just dumb but a lot of these elements don't seem to work? the "..." buttons don't open any flyout, the dropdown doesn't open up...

otherwise looks cool though

I wish I could use this – unfortunately UI frameworks are a political problem at every company I've worked at. The designers feel undermined or threatened by it, and product owners want to dictate design. Despite the massive productivity benefits of a UI framework, I've never been able to convince stakeholders to actually adopt one.
Hey I’m a designer and I love UI frameworks. Why design and build something from scratch if someone’s already doing it for you?

Unless there’s a very specific business case that requires a custom UI it’s not worth the hassle. I want to be delivering value for the business and for users, not maintaining a UI library.

One place I worked at had built an entire responsive CSS framework, which was hard to use and took a lot of maintenance. I threw it all out for Bootstrap (as was the style at the time). Some of the senior devs were upset I’d killed their baby, but everyone else was able to move so much faster.

If you’re showing off a UI framework, I shouldn’t be accidentally scrolling left and right on the page on mobile / my iPhone. Couldn’t be bothered to scroll down the page to look at components while accidentally activating horizontal scrolling.
Broken in Safari on iphone. For example:

- table background moves left when table is scrolled horizontally

- actions in table and dropdown do nothing on tap

- text on buttons is selectable (really?)

im always surprised that Rails is still relevant

i havent used it since 2006 opting for php and django

i might give it another shot, any reason you like this more than django or other frameworks

I have hardware acceleration disabled in Firefox and my 5800X spins up trying to render the background wave. At least that's a known choice I made.
This is interesting to me as someone who worked with Rails a good deal back in the day and has interest in picking it back up.

Any chance of some themes that bring in a little dimension? Doesn't have to be early 2010s Bootstrap or anything but some subtle, crisp drop shadows and gentle gradients would be welcome.

Additionally, is unused Tailwind CSS shaken out or does it all come along for the ride?

I'm generally in favor of "Show HN" posts that are products, but this post just seems like blatant advertising.
Good to see work in non-AI world and for Rails!

I would make it clear in the landing page that the components are for demonstration purposes by adding a title like "For example" before them.

The above the fold looks a bit packed right now. I would leave the login box out until user presses top right as it's for retentive users only.

This definitely does fill a gap that Rails has. I love using it but man I can't make a nice looking front end to save my life. We've used Tailwind UI a ton but thats kind of a foot gun because you end up slightly tweaking classes all over the place if you're not disciplined.
It looks good, but I'll be honest, it's hard for me to consider $299/$799 if I can buy a beautiful theme off of somewhere like ThemeForest for $20 or $30 and toss it into an LLM to get the files parsed into components and templates.
Rails is best as an API only, that's where it shines for me like no other tool.
Waiting for something similar but without Tailwind and with native elements.
I've launched 3 Rails SaaS products in the last 6 months, all profitable. In the world of LLMs things like this feel less valuable. I can kick off a Claude Code prompt and in 1 hour have a decent design system with Rails components.

Things like this likely need to be AI-first moving forward. This feels built for humans.

Did a quick search and no-one has flagged a11y/colour/contrast but the animating effect for the brand colour often had a colour contrast around the 1.0 range.
I'm so tired of this kind of design -- that basic dev tool splash page/Tailwind-y/Shadcdn UI thing that's just seemingly everywhere nowadays. It's so basic and tired, like Material Design without any of the little bits of personality that make it decent.

Give me some life and color and personality, damn it.

I don't do a lot of rails, is this meant to be very drop-in? How generic is the CSS? Asking as a Django developer. ;)
Full-stack Rails has been my day job pretty much exclusively for almost twenty years now, for both long-term projects and one-offs in agency contexts. So I am generally interested.

Two things put me off:

1) I have to hunt around to find out whether this would fit into my project, dependency and workflow-wise — turns out it doesn't. I use neither Hotwire nor Tailwind, and "latest Rails point release only" is a rather harsh restriction too.

IMO, this information should replace the fluffy marketing speak in "Who is Rails UI for?" right at the top of railsui.com/docs .

2) Absolutely every paid product should have a pricing link in the top nav, spelled out in large, friendly letters. If the landing page only implicitly implies "paid product" but is then going to be sneaky about that fact, I close the tab and do not come back; in this case, I only stuck around because it's a Show HN.

Oh, and _that_ perennial topic ... a subscription? No thank you. Especially for the kind of money you're asking, I expect a perpetual license for the version at time of purchase, plus at least a year of updates.

All together: not for me. Best of luck to you!

Hmm, Rails, I wonder if the UI will work well.

I open https://railsui.com/components.

I click on the different components. They switch to a random component after a while.

My confidence in Rails for UI stays were it was :)
