I m restyling a live app screen by screen, with Claude Code doing the edits. My test suite has 262 tests and all of them pass, but none of them check how a page looks. So a change to shared styles could break a screen and nothing would tell me.
Before each change, I have the agent screenshot every screen I m not supposed to touch, using a fake signed-in session and mocked API responses so no real data is involved. After the change, it captures them again and compares them pixel by pixel. Anything that differs has to be explained.
That caught something I would never have seen. 34 screens matched exactly. One modal didn t: 1,334 of about 215,000 pixels were different. To my eye, before and after looked identical. The cause was that my first version moved the page into a new wrapper, and the old container had been quietly centering the modal s heading. The new one didn t. No test would have complained.
It also showed that a modal kept outside the new wrapper still changed colour, because my theme variables are set on the whole page, not just the wrapper. I had to re-scope the old colours around the modal.
Two weeks ago, a tech influencer with about 200k followers made a video about our app. He called it a "hidden gem" for freelancers, and the video blew up. By the next morning, we had 15,000 new signups.
I was ecstatic. I thought we had finally hit our breakout moment.
But by 10 AM, our database locked up. Our AWS instance couldn't handle the concurrent API requests. Users were getting 502 Bad Gateway errors when they tried to log in. My co-founder and I spent the entire day frantically upgrading our database tier and scaling our servers.
By the time the site was stable (about 18 hours later), the damage was done. I pulled the analytics this morning:
The Product hunt community is amazing, and I know there's lots of knowledge to share. I want to make the forums the most vibrant forums for product builders on the internet! To that end we've re-designed forums, defined sub-forums, and introduced product-specific forums, and we've drafted new guidelines to keep the discussions vibrant, authentic, and genuinely useful. The new guidelines are here - https://help.producthunt.com/en/... - you can read them in full, but here's my summary: When posting a new forum thread, ask yourself:
1) Is this a genuine question I have that I want the community to answer? 2) Is this an insight that will be helpful to other builders and product geeks?
Hi hunters, Google domains that many of us keep domains have been sold to another company. It was the cheapest place to buy domains, simple and effective, but again, Google didn't surprise us. My question is where are you planning to move your domains to?
I've been pretty impressed at the amount of products people (including myself) have been able to create which got me curious... do vibe coders or AI-primary builders have a place in a company or team? My thinking is the more technically adept would work on the core-focus while vibecoders can assist with other tasks that shouldn't be the main devs focus...like a potential feature add, minor changes, or even exploring different ways of modifying the existing product. I'm curious what you all think, would you hire a vibe coder?
For the first two years of our B2B SaaS, our UI was functional but ugly. It looked like it was built in 2012 (because it was). Users complained about it occasionally, so we finally decided to invest in a massive redesign. We hired a top-tier design agency, spent three months, and dropped $25,000 on a beautiful, modern, "dark mode" interface with a completely restructured navigation menu.
We launched the new design on a Tuesday. By Friday, our support inbox was on fire.
Within 30 days, our monthly churn rate jumped from 3% to 6.5%. We lost 40 paying customers.
When I started calling the churned accounts to ask what happened, I heard the exact same thing over and over: "I've been using your tool every day for two years. I knew exactly where every button was. Now I have to relearn the whole product. I don't have time for this."
