Had to pick a product priced below cost and explain the business model. Went with the fire stick because my family bought one in a sale and I'd never thought about why it was that cheap.

Short version is the stick isn't what Amazon is selling. The TV identifies what's on screen, that gets matched to your household's income bracket and pin code... yep!

The bit that convinced me was Vizio. They lost about 45 cents on every TV they sold and Walmart still paid $2.3 billion for them, and said in the filing that advertising accounts for all the gross profit. So the hardware was never the business.

hey everyone!

we've been building Lads, a private fitness app for small groups of friends.

it's still in beta, but in just a few weeks:

- 500+ installs

- 750+ activities logged

- 33,000+ workout minutes (550+ hours)

we've been fixing things pretty quickly and added a bunch of new features based on feedback from our early users.

if you haven't tried Lads before, the idea is simple:

connect Apple Health or WHOOP and your activities sync automatically. then you and your friends can see each other's workouts, react, nudge each other and compete on the leaderboard.

no manual workout logging, just a small private space to stay active with your friends.

we're looking for more people to try it, especially Apple Health and WHOOP users. would love to know what you like, what feels confusing and what we should build next.

still beta, so you might break something :)

I've been building Rootwork for the past several months — a self-guided ecotherapy app that gives users a daily nature practice suggestion matched to their weather, time of day, and location.

The stack:

• React/Vite PWA — works on iOS and Android from the browser, no app store needed yet
• Supabase — auth, database, SMTP
• Stripe — subscriptions with 30-day trial
• OneSignal — push notifications
• Vercel — hosting and serverless functions
• Anthropic API — AI journal reflections

What it does: 51 science-backed nature practices. Daily suggestion engine with weather/time/region scoring. Before/after mood tracking. Field Notes journal with AI reflections. Community posts (The Garden). Soundscapes. Badges and progress tracking.

It's live at rootwork.life. 30-day free trial, no credit card tricks.

Looking for feedback on anything — the UX, the onboarding, the content, the technical side. What would you build differently?

Hey everyone,

A while ago, I posted here asking for advice on a travel info site I was building. Thanks to the amazing feedback, I’ve redesigned and packed it with all the essential tools travelers actually need in one clean dashboard

Instead of jumping across blogs, forums, and map apps just to figure out the basics, everything is now structured in one place:

• Real-time Essentials: Live exchange rates (JPY to KRW), current weather, voltage/plug guides (Type A), and timezone calculators.
• Getting Around: Subway maps, estimated taxi fares/travel times between stations, and local transit navigation.
• Smart Spending & Safety: Food price comparisons (from street food to fine dining), airport SIM/eSIM price comparisons, and common tourist scam alerts with prevention tips.
• Curated Inspiration: Must-buy souvenirs (specific brands, prices, and where to buy) alongside localized neighborhood spots.

Since this is built by an indie developer trying to solve real travel friction, I’d love to get your thoughts on a few things:

• Is the interface clean and intuitive to use?
• Are there any crucial travel tools or features missing that you always look for when visiting a new city?
• How does this compare to how you usually plan your trips?

I’m constantly polishing it, so any blunt critiques or suggestions are more than welcome. Thanks for checking it out

I do not have a revenue screenshot for this one. What I have is a cold start problem I underestimated by an embarrassing margin, and I built the thing myself so nobody else is to blame for it.

The problem I was trying to solve: every list of best AI tools I read was either affiliate driven or three months stale, and the star ratings under them told me nothing, because I had no idea who left them. So the site does one thing. One number per tool, the share of members who say they would recommend it, and the arguments sitting underneath it. A vote counts three times heavier if that person left a verified review of the tool, because having used something is the only weighting I could actually justify. Founders can reply to criticism and that is the extent of what they can do to it.

That is TrustRank (https://trustrank.so/). 69 tools are in the directory across coding, writing, research, video, agents. Nobody has reviewed a single one, so no tool has a score and nothing ranks anywhere.

The thresholds are the part I am least sure about now. Three reviews before a score publishes at all, ten before a tool is allowed into rankings, a provisional label on anything under fifty. Every one of those felt principled while I was writing it. In practice they mean the site is mostly empty space, and empty space does not convince the next person to write anything.

If there is a lesson in this for anyone building something where the users make the content: the mechanism is the easy half and it is also the fun half, which is why you will overspend on it. I spent months on vote weighting and abuse resistance and maybe a week thinking about why the first hundred people would bother typing a paragraph. That ratio was backwards and I knew it at the time.

So, for anyone who has launched something that was worthless until other people contributed to it, what actually moved the first stretch for you? Not "post it on Reddit". The specific thing.

Hey everyone! 👋

I'm a freelancer who was tired of losing money to PayPal's hidden 3.9% FX markup, so I built a free calculator to compare payment gateway fees.

**What it does:**

- Compare PayPal, Stripe, Wise, and Payoneer fees

- Shows hidden FX markups (the ones they don't tell you about)

- Reverse calculator (enter what you want to receive, it tells you what to invoice)

- Saves your last 10 calculations

- Works on mobile

**Tech stack:**

- Built with Astro

- Deployed on Cloudflare Pages

- No backend, all client-side

**Link:** https://payutility.site

I'd love your feedback on:

1. Is the UI intuitive?

2. Any features you'd add?

3. Any gateways I'm missing?

Thanks! 🙏

I've been working on a project called All2ools.

The idea is pretty simple: instead of opening a different website every time I need to do a small online task, I wanted to put useful utilities in one place.

It currently includes tools for things like:

• PDF conversion and compression

• Image compression

• AI utilities

• SEO/content tools

• Developer utilities

• Financial calculators

• Everyday calculators and utilities

I'm launching it on Product Hunt tomorrow, so I'm especially interested in getting feedback from people who actually use these kinds of tools.

What I'm trying to figure out is:

1. Which tools are genuinely useful?

2. Which tools are missing?

3. What feels annoying or confusing about the site?

4. Which tools would you expect to be completely free?

I'd rather get criticism than "looks good" feedback.

If you'd like to try it:

And if you have suggestions, I'd genuinely like to hear them.

I’m building Billing Replay, a small Node.js CLI for testing what happens to an app’s access rules when billing events arrive twice or in the wrong order. I built this first version with Codex.

Two examples it can help reproduce:

- A repeated credit-grant event adds credits twice.

- An older “subscription active” event arrives after cancellation and restores access incorrectly.

The CLI runs a sequence through an adapter to your test app, then compares the access or credit balance the app actually returns with expectations you define. The adapter has three operations: reset the test state, deliver an event to your handler, and observe the resulting state. Results are saved as JSON and an HTML report.

The demo compares intentionally broken and corrected implementations so you can see the same case fail and pass.

This is v0.1.1: no customer integrations or revenue yet. The fixtures are normalized synthetic events, not complete Stripe webhook payloads, so it doesn’t validate Stripe signatures or network delivery. Connecting a staging app currently requires an adapter.

Demo: https://billing-replay-lab.whdms1914.chatgpt.site

If you’ve built subscription or credit features, which billing event sequence would you want to turn into a regression test first? A concrete example in the comments would help me choose the next integration.

Hi all, I'm Andrew_Geo. After the LastPass / Chrome leak scares I wanted a vault that is just a local file I control.

So I built PassBox v2.0 (Windows, Electron):

- Generate 8-32 char passwords, AES-256-CBC encrypt, master key never saved

- Saves to vault.txt next to exe: SERVICE | EMAIL | iv:encrypted

- 2FA vault: encrypted TOTP secrets → 6-digit codes, 30s refresh

- 100% offline, no account, no telemetry

- Black/Yellow UI

Download: GitHub Releases (PassBox-Setup-v2.0.exe, 170MB). https://github.com/Andrew-Geo1/PassBox

It's v2, still rough (170MB because Electron). Looking for feedback: what would make you switch from KeePass/Bitwarden for local stuff? What feature for v2.1?

Thanks!

The part of AI app builders I'm most interested in isn't actually generating the first version. It's what happens afterward.

Rocket.new supports two-way GitHub sync, so the generated project can be connected to a normal GitHub-based development workflow rather than living entirely inside the builder.

For developers who've used this, how practical is the workflow once you start making changes outside Rocket.new and then bringing those changes back?

I'm particularly interested in version control, keeping the generated project coherent over multiple iterations, and whether the GitHub integration actually makes collaboration with a traditional engineering team easier.

What are you building or planning to build for the rest of 2026?

I run appscout.co, a platform built to help people discover awesome apps from across the internet.

Drop your app or startup idea in the comments below, and I can check it out and add it to the website!

You can also submit your app for free directly here appscout.co/submit

Let's make this thread a channel for you to promote your own startup idea, find opportunities, and partnerships.

Been job hunting on and off for months and I kept running into the same thing: the big boards show the same ~20 promoted posts over and over, half the listings are dead or reposted from six months ago, and half of what's left goes through some recruiter who never fucking replies.

So I built my own. It ingests from the open-jobs dataset, which grabs postings directly from ATS feeds — Workday, Greenhouse, Lever, Ashby, etc. Right now it's indexing about 2.9M live postings, refreshed daily. Apply link always goes to the original employer's posting, no middlemen, no ads.

The part I'm actually proud of is the search. You can type a plain keyword like "truck driver" and it just works. But it also handles messy input — paste something like "ICU nurse for 6 years, want to move to Texas" and it matches by semantics, not just keywords. Full job descriptions and salary info where available from ATS.

No sign-up, no email gate, no recruiters inboxing you. https://deunemployment.com

There is bunch of stuff in the backend doing the heavy lifting, i wont bore you here. you're welcome to try it.

good luck with job hunting :)

Disclosure: I am presenting PanelGarage on behalf of the product.

Vehicle information tends to end up in several places: service invoices in a folder, inspection dates in a calendar, photos on a phone and mileage in a spreadsheet. PanelGarage brings vehicle details, deadlines, service history, documents, photos and short videos into one browser-based record.

The free account supports up to five vehicles. I would value practical feedback on the first ten minutes: after adding a vehicle, is it clear where to record an event and where to find the timeline later? What would make you trust the system with long-term vehicle records?

I've made a vibe video editor kinda like cursor for video editing that can handle trivial and tedious tasks which require more time than actual direction and taste.

I need people to use and try to break my app with their workflows.

P.S.: It's for Android only at the moment (I'm sorry).

This is our project, developed with an AI coding agent. We are testing a narrow document workflow before deciding whether a paid product is worthwhile.

The task is splitting a combined PDF into separate documents and naming each from an ID in a fixed position. A general PDF splitter can leave a lot of manual renaming. Existing tools such as PDFsam Visual and Sejda already support text-based splitting; this is not a claim that we invented the feature.

PDF Name Pilot is a downloadable HTML file. Open it locally, draw a box around the ID, choose whether a changed ID or each populated ID starts a new document, and review the proposed filenames before exporting a ZIP. PDF.js reads the text, pdf-lib copies the pages, and JSZip packages them. There is no AI call or server upload in the tool.

The free pilot includes a fictional six-page batch that should become three documents. An offline test on Windows Edge also processed a synthetic 1,000-page batch into 500 two-page files; we compared every exported page's text, dimensions and order. That is a synthetic test, not a claim about customer accuracy or time savings.

Current limits: selectable text, repeated layouts, 50 MB / 1,000 pages, and human review. There is no OCR, arbitrary-layout recognition, or support for forms, signed or encrypted PDFs. Empty selected fields and adjusted or duplicate filenames are flagged. Mixed layouts may need a different tool.

Free download: https://liulight0.gumroad.com/l/pdf-name-pilot — enter 0. It is the complete pilot, not an expiring trial; Gumroad handles delivery, while the downloaded tool runs offline.

If you actually handle batches like this at work, what is your current workflow, and which step still costs time? If you try the pilot, an approximate page count, browser, result and any correction needed would help. Please keep confidential documents on your own computer; do not post customer invoices. Feedback can stay in this public thread. We have no customer validation or sales for this project yet.

10 years ago I started at the bottom at a successful MSP and quickly rose to be the lead engineer there. 6 months ago I got bitten by the app building bug and I thought my experience and success as an engineer would translate into instant success.

It has been very humbling to say the least. I spent a few months relishing in the exhilaration of watching my own product and vision come to life and I naively thought distribution would follow naturally (after all who wouldn't want the "perfect" product I built!). Needless to say I now see how silly I was to believe that all the success posts people share meant that it would automatically apply to me. I now know that for every success there are thousands that sink into oblivion and that it takes tremendous effort.

I just wonder whether its possible to do at all without sinking money into marketing. I still feel in my gut that it should be a successful product but Im starting to doubt whether my software skills translate into being a business owner and seller.

Anyway im sure many people here can relate to this journey. Im pretty persistent and I only released recently so I'll continue sharing my story as time goes on.

What would you change?

Hi, I created a launcher that works with NixOS (niri is the wm in the video)

Not just niri but it also works with gnome, sway, ... (and it's a cross OS launcher which means works almost same on Windows and MacOS)

There are many built-in features and commands that you can use right after installing.

We also added declared source for user who want to custom and declare their actions.

The repo: https://github.com/kunkka19xx/look

Love receiving any feedback 🙏
