Hi ProductHunt I'm building open payment network for vehicles - Would love some feedback!
Building the middleware + hardware to create an open payment network for vehicles, one tag and one wallet across: drive-thrus, parking decks, car washes, game-day lots, and your work parking deck (access only). Say you got a free windshield tag. It works like a highway toll tag, but for everyday places. You link a card once, then pull up and drive through without rolling the window down for payment. It connects directly to your loyalty program (where available). Would you put it on your car?
If yes, where would you use it first?
If no, what's the dealbreaker? Tracking, surprise charges, card security, a sticker on your glass, or too few places that take it?
Would you want to approve each charge, or just let it go through?
Do you already have a toll tag or a car wash club sticker? What do you like or hate about it?
Would you pay a small fee say $2.99/mo to have access exclusive deals in this merchant network? Eg. 10% at parking garages or your favorite fastfood chain.
Piloting with a fast-food chain but running into the chicken-and-egg problem: not enough drivers to get merchants, not enough merchants that drivers can use it at. Any ideas on which side you would seed first?
Clients comment on your live site, pinned to the exact spot
Hi everyone, I'm Billal.
I'm building PinReview, a tool for collecting website feedback from clients.
Your client opens the live site, clicks the exact spot they want to change, and leaves a comment. Each comment becomes a task on a board, so nothing gets lost in emails or WhatsApp threads.
Two decisions I made early on:
Looking for 8–10 paper traders to try two charts
I'm Wang Can, and I'm building Keenpath for people who know basic candlesticks but still get stuck reading a new chart.
We're inviting our first testers. Our goal is to build a chart-reading practice tool traders will want to open every day.
The free demo lets you try two chart-reading exercises without signing up. You answer short questions and get written feedback based on your choices. The exercises use simplified wave charts created for practice.

I'm looking for 8 10 English-speaking learners, aged 19 or over, who are currently paper trading and have been learning charts for roughly 1 6 months. Could you try the two charts?
I want to find out where the explanations help and where they still leave you guessing on the next chart.
After trying them, leave one comment: where, if anywhere, did the question or explanation leave you guessing?
Update, Oct 17: A trader says, "I'll sell at 107." When the price drops below it, he says he'll wait for 103. That's the setup for my new fictional Keenpath trading story:
I'm also working on a beginner lesson showing how a candlestick forms as price moves. What would you most like it to explain about the body and wicks?
Building Crayon: Features I always wished existed in Canva
A year ago, I started building Crayon because I wanted a creative editor that combined the simplicity of Canva with the power of professional design software.
As I kept building, I realized creators often had to jump between multiple apps just to finish one project. Design in one app, animate in another, edit vectors somewhere else, then export and repeat.
I wanted to solve that.
Here are a few features I'm most proud of:
Why I built HeyPapin: AI shouldn’t just do the work for us—it should teach us how to think
Hey Product Hunt!
I m Andreas. I ve always been passionate about education and the transformative potential of technology.
Like many of you, I believe AI is one of the most incredible innovations for humanity. But recently, I noticed something concerning especially among students and young learners.
An AI assistant for unknown callers
Launched my first Mac app today and it's at 0 upvotes. What would you change?
I'm Krishan, solo dev in the UK. DiskFox is a Mac app that keeps a history of your storage, so instead of "System Data: 80 GB" it tells you what grew and when, like Spotify's cache coming back a week after I cleared it.
Launched it here this morning and it's sitting at #251, so clearly something isn't landing. Would genuinely like blunt feedback:
- Is the tagline clear? ("See what's eating your Mac's storage, and why")
Building in Event Tech — What’s Everyone Working On?
I m building Tendr, an event-planning platform, and curious about what others are building in the event tech space.
Is the industry too crowded, or are there still major problems waiting to be solved?
Would love to hear about your products, ideas, and experiences. Let s connect!
Hundreds of applications, zero replies — so I built JobTune. What would you add?
A few months ago I was applying to a lot of jobs and just not hearing back.
I was tailoring my resume, putting in the effort, doing what you re supposed to do. Still mostly silence.
I eventually realized my resume might not even be reaching a human. ATS systems were probably filtering it out and I had no way to see what was wrong.
So I built a simple tool for it.

I built an iOS resume builder. Would love feedback on the app
Hey everyone!
I'm an indie developer working on Make Resume, an iOS app that helps people create professional resumes without spending hours on formatting.
The idea is pretty simple: make resume creation faster and less frustrating, especially for people applying for their first job or updating an old CV.
What I've built so far:
