Show HN: Rails UI

Re:Show HN: Rails UI by ChadMoran on Wednesday January 21, 2026 @06:56PM (#46713398)

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.

Personally, if I feel like you vibe coded your SaaS I’m probably not gonna pay for it. You can obviously tell when a project is vibe coded just based on the way it looks, the weird bugs you see and the poor documentation.

There’s definitely a market for good looking UI that actually works and stands out from the vibe coded junk. Artisanal corn fed UI I guess.

Same here. This was human driven UI. I used AI sparingly for mostly architecture decisions on the gem. Otherwise all by hand. I'm a product designer by trade.

AI is an effort leverage tool, not a thinking one.

If you know what you're doing it can truly accelerate your work.

I agree.

None of mine are vibe-coded. They're making a competent engineer like myself - more efficient.

The roadblock for me is the coding part, not the idea part.

Maybe they used AI to make this ? But really though I hope they didn't and did some of designing themselves... I'm worried we are approaching a world where we never get new human designs just regurgitated designs from pre 2025.

I used AI sparingly actually. Mostly just some help for Ruby gem architecture and how to approach swapping themes on the fly otherwise all me. I'm a product designer by day so this stuff I do constantly.

I came here to say: Is someone going to tell him? Glad I’m not the only one to be like “Wait.. I can do this with an agent in no time”.

In fact, armed with Context7, Claude could recreate this whole business model in a day.

Definitely aware. I built it to scratch my own itch to be honest. I'm going the non AI route with it. Lotta slop out there. I'm sure it will improve but I'm fine with this being a side gig.

Any chance to reach out to you? I'd like to ask you some questions about those SaaS (not in a bad way, just trying to learn)

That's fair. I think there's a future where some folks won't want AI to generate all the things. I replied to another comment before but this was very little AI minus some architecture direction of the underlying ruby gem.

I definitely don't AI-generate all of the things.

For me it's a bandwidth increaser for the tedious parts.
