WattPair — a power-station calculator that refuses to print numbers it can't source

Built this over six months of nights and weekends: wattpair.com answers "will this battery power station actually run my fridge / CPAP / air conditioner - and for how long."

The twist: I have no lab, so the engine only uses manufacturer-published numbers, and when a number doesn't exist it says so instead of guessing. 23 of my 29 station entries have no published usable capacity - those pages print no runtime at all, with the reason.

The Boss Has Gone Crazy—So I Built a Better Way to Shop Designer Sales

Hi Product Hunt!

I m Jinny, the solo founder and developer of Crazy Sajangnim.

The name comes from the Korean sale phrase , or The boss has gone crazy. It is commonly used when a store offers discounts so dramatic that the owner must be crazy to sell at those prices.

That idea became the inspiration for Crazy Sajangnim: one place to discover genuinely discounted designer fashion across Korean and U.S. retailers.

I built a marketplace for reusable AI skills — where every listing has to prove it works

Hi everyone!

Over the past few weeks I've been building Skill Exchange, a marketplace for reusable AI "skills" SKILL.md / system-prompt files that teach an assistant a specific workflow (generate a branded PDF, scaffold a Chrome extension, write in your voice, audit code, etc.).

Standups, calendars, invoices - records of the same week. Which one does your team actually trust?

Something I keep bumping into with small teams: we generate the same week three separate times, in three different places, and none of them agree.

1. The daily update. Standup, a Slack thread, a "what did you do today" bot. Everyone writes it. I'm not convinced anyone reads it a week later.

I built 9 live QR codes so you don't have to imagine what my product does 👇

Hey makers I'm Zahar, solo founder of PixlQR launching here this Thursday (Aug 6).

I spent 8 months building this and my biggest lesson came last week: people don't want to read about a product, they want to see it work. So instead of describing it, here are 9 live QR codes you can open on your phone right now

Medical ID https://pxqr.io/7ivhv
Event https://pxqr.io/gfdz1
vCard https://pxqr.io/qn1ct
Feedback https://pxqr.io/pvtaw
Menu https://pxqr.io/obih9
Coupon https://pxqr.io/bxu3o
Reviews https://pxqr.io/g7pdy
Payment https://pxqr.io/0ztqn
File https://pxqr.io/6v3w6

Why I built it: every QR tool I tried had the same problems you can't edit a code once it's printed, the analytics tell you nothing useful, and the "QR types" are shallow. PixlQR fixes all three. Every code above is dynamic (I can change where it points without reprinting) and every scan is tracked in real time location, device, time. These are 9 of 24+ types.

Browser Use Ranked: Production Readiness for AI Agents

We compared open-source browser agents, hosted APIs, and remote browser runtimes for AI workloads. The goal was to see which approaches are actually ready for production, not just demos.

Key findings: open-source agents are flexible but often fragile in real-world automation. Hosted APIs are convenient but can lock you into specific models. Remote browser runtimes offer a middle ground, but they vary in stability and security.

The most dangerous team signal is silence.

Not every problem starts with conflict.

Most team problems don t begin with a dramatic moment. They begin quietly. One person stops sharing ideas. Another one says I m fine too often. A team lead senses something is off, but has no clear signal yet.

Pulseboard helps remote and hybrid teams create a simple rhythm of check-ins, so stress, energy and workload become visible earlier.

  • Not as another survey.

  • Not as another dashboard.

  • But as a lightweight signal system for teams.

The Story Behind StudyFlow AI

I noticed something while studying for exams.

Everyone says "study smarter."

But most of us still spend hours reading PDFs, highlighting random sentences, and rewriting notes.

I built StudyFlow AI because I wanted the opposite.
