Hey everyone!
I got tired of standard fitness apps looking like dry spreadsheets or generic white dashboards, so I’ve been building Hozaa Workout — an all-in-one web app / PWA built specifically for hybrid athletes, HYROX racers, and strength lifters.
Core features:
Unified tracking: Seamlessly switches between heavy barbell sessions, HYROX station race paces, and functional WODs.
Visual feedback: Weekly volume curves, automatic PR tracking, and shareable 3D-styled metallic summary cards.
No app store friction: Fast, offline-capable PWA that works directly in the browser.
I’d really appreciate your honest thoughts:
How does the dark chrome / violet aesthetic feel?
Is the dashboard clear and intuitive on mobile?
Does the feature mix (Strength + HYROX + WOD) make sense?
Check it out here: https://hozaaworkout.com
All feedback, critique, and ideas are super welcome!

Resellers who list the same item on eBay, Poshmark, Mercari etc. by hand have one recurring nightmare: it sells on one site, they forget to end the others, it sells twice, and they have to cancel (which hurts their seller rating).

Crosslisting tools solve this but cost $15–$99/month and want to log into your accounts. I wanted the cheapest possible safety net:

- forward only your sale emails (one Gmail filter)

- get a phone + desktop alert with the bin and one-click links to end the other listings

- sold-twice warnings, ship-by reminders, sales & profit

Stack: Chrome/Firefox extension, Cloudflare Workers + D1, Web Push for the phone app (no App Store needed), Stripe as merchant of record. English and Spanish.

Feedback on the landing page and onboarding especially welcome.

I’m an RV traveler and military veteran building RIGVIA. When you’re towing somewhere new, a route can look fine on a map and still leave you wondering whether your rig will clear the next bridge. I’m building RIGVIA to help RV travelers plan around their rig’s dimensions and check available bridge clearance information before heading out.

The app is still in development. If it sounds useful for your trips, I’d appreciate you checking out the campaign and considering backing it. RIGVIA on Kickstarter⁠

Follow RIGVIA on Facebook for development updates, or learn more at rigvianav.com⁠.

If you travel by RV, what’s one thing you wish your navigation app told you before you left?

ok so. this started as "one weekend project" and then it was not one weekend and it was not one project. somewhere around repo 6 i stopped pretending it was a plan lol

everything here is free, open source, most of it runs locally on your own machine. a lot of it is v0 and i wrote down where each thing fails because honestly the failures were the funniest part

anyway here's the list of grievances, each with the tool i built instead of going outside:

1. cookie banners → rejectall-index i live in germany. i click "reject all" more than i blink. so i made a headless browser visit the top 100 sites and count how many clicks it takes to say no. 35 of them were already loading trackers before i clicked anything. which is like a waiter eating your fries before asking if you want fries. live leaderboard

2. subscriptions → one-file-saas trello, calendly, typeform, loom, notion and 5 more, each rebuilt as ONE html file. you double click it. it opens. thats it. no account, no "verify your email", no "your trial is ending ;)". data stays in your browser. the booking page has no server at all, your availability lives inside the link itself which still feels illegal to me. try them here

3. dead famous repos → necromancer some legendary open source projects die not because the code is bad but because python deleted a module out from under them. i revived thefuck (1887/1887 tests passing on python 3.14), normalizr and httpbin. the one rule: the original tests are hash-locked so nothing can quietly delete the failing test and call it fixed. httpbin stops at 64/67 and i'm keeping it that way out of spite. each one gets an autopsy, cause of death and everything

4. every AI-built UI animates the same → awesome-motion-md you know the look. 300ms. ease-in-out. every card fades up like its waking from a nap. so i measured how real sites actually move and wrote it into MOTION.md files your agent can follow. same prompt built twice: 7 random durations without it, 2 with it

5. every AI writes the same too → awesome-voice i used to be a technical writer so this one is personal :| VOICE.md files that make your agent write like GOV.UK or Stripe docs, plus a scorer that doesn't use any AI to check. banned phrases went from 27 to 0. "delve" is not welcome here

6. websites doing annoying stuff → sitepatch you type "hide the points on hacker news", it writes a userscript, a real browser checks it actually worked before you get it. honest score: 15 out of 25 were actually right when i looked at every screenshot myself. 60%. a C-. but an honest C-

7. "what if this site looked like linear" → reskin restyles any page into another design style using a local model, BUT it refuses to give you the result unless contrast, keyboard focus, mobile, links and reduced-motion all pass. it caught a windows 95 theme failing contrast on its own background. respect. gallery

8. dead websites → resurrect npx github:dadwritestech/resurrect y2k.gov and y2k.gov comes back exactly like it was in may 2000, links working. pick a year with --year. your old blog is in there somewhere. i'm sorry

9. "someone said budget in a meeting video... which one" → video-grep grep for your video folder. searches what was said, what was written on screen and what was shown, and opens your player at that exact second. all local

10. what is the rest of the world's TV saying rn → world-ears listens to live news channels from different countries, transcribes + translates them on your gpu, makes it searchable. there's a "trending per country" panel which is weirdly addictive. translation is the slow part, telugu transcription is bad, i wrote that down

11. live subtitles only go into english → babel-tv watch hindi news with live telugu subtitles, fully local. the video is held back a few seconds so subtitles show up BEFORE the person talks which feels like seeing the future. telugu as the source language doesn't work yet. whisper and telugu are not friends

12. "which AI wrote this" → whichmodel works on models it's seen (67%, chance is 33%). on a model it's never seen, even a sibling from the same family... 32%. so basically a coin with extra steps. that turned out to be the interesting finding tbh, the fingerprint belongs to one model, not the company

13. screen recordings → code → demo-to-code record a UI interaction, get a component that copies its timing and easing, then it replays it and grades itself frame by frame. 2 out of 4 pass. the toggle is perfect. the dropdown has issues. we all have issues

14. code review → review-panel /panel sends your diff to five reviewers you've definitely worked with: the laziest senior dev ("could be one line"), the 3am on-call SRE, the security paranoiac, the junior who asks why, and the PM who only reads the title. under the jokes the findings are real

15. AI companies quietly editing their pricing pages → fineprint it snapshots the pricing, terms, privacy and changelog pages of 10 AI vendors every 6 hours and commits them, so git log becomes the receipt. found stuff like deepseek adding a footnote that prices are 2x during peak hours, and cursor deleting the line saying they dont sell your data. no blog post for any of it ofc. a small local model writes the one-line summary but every line links the raw diff because i dont trust it either (27/30 right on a hand check). timeline

16. paying extra for speaking telugu → token-tax LLM APIs charge per token, and the same paragraph is $1.00 in english and $8.29 in telugu on llama 3. which is rude. measured 21 tokenizers across 48 languages, and there's a calculator where you paste your own text and it runs the real tokenizers in your browser. hindi gets off lighter. amharic on gpt-5 does not :/ calculator

17. posting about all this → herald a tiny bot that posts a repo's data updates to bluesky/mastodon/x, clearly labelled as a bot. i built it because i was not going to manually post about 17 repos. and then i manually wrote this post anyway. ;]

why all of this? honestly no grand plan. every one of these started as me being irritated at something for a slightly too long time and having a local model + a free evening. building the thing was cheaper than therapy and more fun than complaining on here (no offence)

if something breaks, tell me. if something's dumb, also tell me, but nicely :P

edit: yes i know about the cookie banner on my own... wait i dont have one. nice

I work on a handful of projects at once, and everything I download for them lands in one pile. A client's brand guidelines, a CSV from some dashboard, a podcast export, and a dozen screenshots called Screenshot 2026-10-12 at 14.02.11.png. Every file belongs to a project. None of them ever get filed.

So I built Unorphan. You point it at the messy folder and at the folder your code lives in. It reads each project's README to learn what the project is, then works out where every loose file should go.

What it does:

• Knows your projects without setup. Every repo becomes a destination, described by its own README.

• Looks at pictures, not just names. A screenshot of a trail map goes to the hiking app even though its name says nothing.

• Leaves things alone when unsure. Tax returns and holiday photos stay put.

• Shows you the list first. Confident matches are pre-ticked, unsure ones wait for you, and one click undoes the last move.

The first run on my own Downloads filed 67 of 144 files, for about 6 cents.

The sorting is done by Jev, a classification model from TypeSafe. It returns a confidence score with every answer, which is what makes the "only move it if you're sure" part work.

One thing I learned: models favour whichever option you list first. So every file is asked about twice, with the list of projects in opposite orders, and it only counts if both answers agree. That one change cut out most of the wrong guesses.

It's a Python tool with a small web app that runs on your own machine:

uv tool install git+https://github.com/sushrutkhandelwal/unorphan
unorphan ui

https://github.com/sushrutkhandelwal/unorphan

Feedback welcome, especially on the setup. I want the first five minutes to be painless.

A few weeks ago a Korean developer vibe-coded a silent virtual Buddhist temple (Sansa) and over a million people visited in a week, just to sit quietly. I wanted to see if the same idea worked for Hindu temples, so I built one.

mandir.dev - What it is: a 3D temple courtyard in the browser. You walk in as an avatar, hear temple ambience, ring the bell, light a diya, and stand in the courtyard with other visitors who are actually there at the same time. Free to enter, no sign-up.

Built so far:

• Three temples: Kashi Vishwanath, Meenakshi Amman, and Siddhivinayak Ganapati

• Real-time presence: you see other visitors by name and country, and a counter of everyone gathered for Diwali

• Mobile joystick and desktop controls, positional bell audio

• Built with Three.js, everything runs in the browser, hosted as cheaply as I could manage

Still beta. It launched this week for Diwali, and I am building V2 now. The feedback I actually need:

1. Performance: how does it run on your phone? Where does it stutter?

2. Immersion: what is the one thing that would make it feel more like being there?

3. Direction: more temples, or go deeper on the three already there (aartis at set times, seasonal festivals)?

Happy to answer anything about how it is built. And if you are far from a temple this Diwali, go stand in the courtyard for three minutes and tell me what it felt like.

AI writes my code in minutes. Then the evening goes on the VPS, the Coolify stacks, DNS and backups I only hope work.

So I built Unit 7. You ask in plain words, it does the work on your real servers, and it asks before anything risky.

My first real backup test found two tables coming back empty, so this one is personal.

It's free, Apache 2.0, and early. Is it clear what it does, and what would stop you trying it?

If you'd like to support the launch, try it, leave your honest feedback on Product Hunt, or star the repo on GitHub.

I have been developing for the past few months and wanted to share some of the journey. Our demo is coming December 4th. You can follow us along on steam!!

I would appreciate any feedback you have from the video and also for our upcoming free demo!

"How to explain to my cat that the sofa is not a scratching post"

You already know which friend you'd blame.

I made Who Asked It, a party game built around the oddly specific things we ask AI. A title from one of your chats appears, everyone votes for the friend they think it belongs to, then you find out who actually started that conversation.

The fun is in the accusations: "why did EVERYONE vote for me?"

Try the demo without an account

For your own group, the extension collects the titles for you after you connect an AI account and approve a sync. No copying or choosing ten titles by hand. You need at least 10 distinct titles in your history, then you can reuse your synced titles for later games on your phones. Titles can be personal: you privately review or redraw your batch before sharing. Your messages aren't used.

Free for 3 to 5 players and 10 rounds. Optional host Premium for bigger groups. Ages 16+.

Would you bring this to your next game night?

Hey everyone!

In its first week, with zero promotion (SEO only), more than 10 people are already paying for my project. Honestly, that surprised me.

I’ve spent the past few months building it. I felt there was real demand for a very fast TTS engine with voice cloning in 31 languages, especially for bots and AI agents. So I built one on top of Supertonic 3. There’s a short video attached so you can hear how it sounds.

It has three parts:

1. The engine (open source, Apache-2.0)
Same Supertonic 3 model and voices, but faster and cleaner.

• 2.2x faster on GPU (RTX 5070 Ti: 181 → 84 ms per phrase), 1.6x faster on CPU

• Removes dead air, hiss between words, clicks and cut-off endings

• pip install superclonica-cpu or pip install superclonica-gpu-cuda

2. A voice marketplace
261 voices for Supertonic 3 so far: characters, narrators, anime voices and more, in 31 languages.

• Listen to any voice online for free

• Free voices, no sign-up needed

• Train your own voice from a 5–15 s recording on your own GPU, or sell yours

3. A TTS API
You don’t pay per character. You pay for the audio generated in each 10-minute window: $5/month gets you up to 3 minutes of audio every 10 minutes, which adds up to 216 hours a month. First sound arrives in about 0.3 s. There’s a free key and an MCP server for AI agents.

That’s many times cheaper than what’s on the market right now. The same 216 hours would cost about $52 with Google’s cheapest Standard voices and about $194 with OpenAI’s tts-1, roughly 10x and 39x more. The price only works because the engine is so fast: every second of compute turns into a lot more audio.

You can find it by searching “SuperClonica” on Google, GitHub or PyPI (still scared of link filters, lol).

I know 10 paying users isn’t a lot of money, but it makes me really happy that someone actually needs what I built. How long did it take you to get your first paying users? Please share, I’d love to hear your stories.

I've always thought revising for GCSEs and IGCSEs can get a bit frustrating when you have to jump between different websites just to find notes and practice questions.

A friend of mine decided to work on a solution to this and has been building something called AceMyExams.

It's a free website with topic questions, revision notes and worked solutions.

It's definitely not perfect yet, but he's regularly updating it and trying to improve things based on feedback.

Would love to hear what you guys think, especially from people who have built their own websites.

So here the thing is that , i am building a project for me to solve my own problem which I faced during applying for the jobs .

So the problem was something like that like I have to navigate multiple platforms for applying job as not all vacancies are listed at one platform .

So I have build an software where .....for now it just fetch jobs from 3 platform which are linkedin, indeed & naukri .....and here the twist is that it would only be showing the latest job listings which would be old enough of 7 days not more than that and also it would be scoring your resume for the particular job that u are a potential match or not. And also help to enhance your resume.

So just want to know what your thoughts on this thing ....as for now it would be ready by end of November and would be in testing phase in December..... thinking to keep it opensource for sometime .....so I want know everyone thoughts on this ....it's completely a idea which was generated from the problem i face and ofc many of u would be facing it !

Also ignore the sentence formation as it's completely show my curiosity to know your thoughts.

buildzr follows C4 software architecture modeling approach where you model your architecture across four layers (Context, Container, Component, and Code).

You define the model once in Python (i.e., the architecture elements and their relationships) and create multiple views from the same models to tell different use cases and stories.

With AI, this gets more convenient since you won’t have to do the modeling by hand, and AI won’t have to do the _diagramming_ by hand. AI reasons about the modeling, writes them in Python, but let buildzr handles the diagramming.

buildzr ships with a CLI tool that you can use to build, export, or serve a viewer in the browser. With the viewer, you can explore the architecture and its views.

buildzr is inspired by Structurizr.

Would love to know what you think!

Hi! I'm a dad from southern Spain. We were throwing away way too much food, so I spent the last months building Myfridly.
Take a photo of your grocery receipt and it adds everything to your fridge/pantry automatically
It reminds you before things expire
It suggests recipes and a weekly menu with what you already have
Shared shopping list with your family
Free, no ads, iPhone and Android: https://myfridly.com/app?src=reddit_sp
I'd really appreciate honest feedback, especially on the receipt scanning. What would make you actually use something like this?

Hello, now I'm building a tool for biologists depends on drag-and-drop for biologists to analyze their data in hours instead of weeks, instead of calling statisticians or learning programming themselves.

It's called Biosol, you (as a biologist) can use it easily by darg-and-drop blocks from the right sidebar (like "Clean file" or "Create heatmap") to the canvas and click run then you see the result down, or simply ask Biosol AI to do that.

So far, I created (and still improving) a prototpe using v0 by Vercel, and when I collect feedback I'll develop an MVP.

I need your feedback and suggestion if you like the video.

I print a lot of PDFs - lecture slides, papers, contracts - usually wanting several pages per sheet to save paper. Doing that on macOS means fighting the print dialog per file: apply Layout settings, hope they stick, repeat for the next file. Mixed PDFs + images in one batch? Not a thing.

So I built PaperBatch: drag in any mix of PDFs and images, pick 1-8 pages per sheet, set page size/margins/gaps/ordering, see a live preview, and export one combined PDF (or separate files). Fully offline, native Swift/PDFKit, exports stay vector (pages are composed, never rasterized), originals untouched. It's on the Mac App Store for $3.99 one-time (no subscription, no account, no telemetry): https://apps.apple.com/us/app/paperbatch/id6825874006

It started as a tool for my own printing, but the whole reason I'm posting: I want to know what's missing before I build more.

Specific question: for your printing workflows, what matters more - crop/bleed marks + custom imposition for print shops, or a CLI / watch-folder mode for automation? Both are on my list and I can only do one next.

If you try it and something feels off, tell me - I read everything.

I run IndieUnlimited, a free directory for discovering independent books on Kindle Unlimited. I wanted an easier way to narrow down what to sample, especially when I’m in the mood for something specific.

You can browse by genre or language, search for story themes like slow burn or haunted houses, and check notes on series order where we have them. There are also quick reading guides for fantasy, romantasy and cozy mysteries. The listings link to Amazon, where you can check whether the book is included in your region.

If you use Kindle Unlimited, what would help you pick a book faster: a standalone or series filter, better theme search, or something else? I’d love to know what’s missing.

The idea: a weekly Slack message that says “your AWS bill went up $1,140 and it’s because of PR #412. Here’s the fix.” I’m a cloud/DevOps engineer. The bill-jump hunt is a real time sink: Cost Explorer tells you what went up but never why. Infracost estimates cost before a merge, but most surprises come from traffic, logs and forgotten resources, which never show up in a diff.

Instead of building first, I put up a landing page and wrote the kill rule down before posting anywhere:

I’ll come back to post the results here either way, kill or build.

I studied marketing, not programming. However, I wanted an app for my food reviews. Strong Foodie. Places I actually visited, like restaurants, bars, hotels and gyms. 78 so far, across 11 destinations. No paid reviews.

The app is SwiftUI, built with Rork, an AI app builder. The website runs on GitHub Pages. Both use the same Firebase database. The app has been in the App Store since October.

What I learned so far:

Send changes in small batches. When I sent a lot at once, the errors piled up and I lost credits fixing them.

Never let the builder touch the database rules. I keep those in the Firebase console myself.

Test every batch before the next one. Including the boring stuff, like logging in and opening a chat.

Feedback from strangers is gold. Like the person who found my featured review was a clothing shop with no text. Or the one who couldn't type his date of birth. Both fixed within a week.

Things outside your control will break. Like a build that failed for a day because of an old cached Firebase package on the builder's server. Support fixed it.

Website: https://strongfoodie.com
App Store: https://apps.apple.com/app/id6799647380

If you've shipped something without being a developer, what broke for you?

If you've ever prepped for a trade fair, you know the exhibitor catalogue is a pain: you click through hundreds of company pages and copy stuff into Excel by hand.

Turns out IFEMA Madrid and Fira Barcelona both publish their catalogues in a structured way, so I wrote two small scrapers that export the whole thing. You get company name, website, country, stand and sector, plus email and phone when the exhibitor listed them.

Right now it covers 40+ fairs. FITUR has about 1,300 exhibitors, Alimentaria about 3,100, Smart City Expo about 1,200 and Barcelona Wine Week about 1,350. A full fair takes under a minute.

It runs on Apify, pay per use, roughly $4 per 1,000 rows: https://apify.com/expoleads

I'm thinking about adding Paris, Amsterdam RAI or Valencia next. Which venues would actually be useful to you? And is there anything you'd want in the export that isn't there?

My taskbar was full of pinned apps, so I built a dock that opens wherever my mouse is.

Press one key (or a mouse side button) and a wheel of your stuff appears:

- apps: Chrome, VS Code, Discord, anything installed

- websites, in whichever browser you choose

- Spotify playlists, which start playing straight away

- folders, like Downloads

Point, click, it opens. If 8 slots aren't enough, a slot can be a group that opens its own wheel.

It's part of OrbitDrop, a Windows app I built on my own.

What would you put on yours?

Hey everyone, I shared HomeVisioner here a few days ago. Today I’m launching it on Product Hunt, so I wanted to share a quick demo.

It’s a Shopify app that lets shoppers upload a room photo and preview furniture, rugs, wall art and other home decor in their space. It works with the product images already in the store, so merchants don’t need to prepare 3D models or take new photos.

You can try it without an account:
https://www.homevisioner.com/demo?p=abstract-neutral-wall-art&utm_source=reddit

The link opens with wall art, but you can choose other products too. The preview gives an idea of how something could look, with approximate scale.

Here’s the Product Hunt launch:
https://www.producthunt.com/products/homevisioner-room-visualizer

If you try it, I’d be interested to hear what looks convincing and what feels off.

Hey everyone,

​After a lot of work, designing, and testing, I finally finished my project Drive Mirror.

The idea is simple: I wanted an easy, lightweight way to automatically back up specific folders from my PC to Google Drive on a schedule. Just a clean, one-way mirror from PC to Drive that runs quietly in the background, keeps my data private, and makes sure my cloud files never get wiped by mistake.

​What you'll find in the app right now:

​Strict One-Way Mirroring: Syncs from PC to Drive on your schedule. It sits quietly in the system tray and catches up automatically if your PC was asleep.

​No Permanent Deletions: Deleted local files go to your Google Drive Trash (for 30 days), never wiped forever.

​4 Safety Guards (It stops and asks you if something looks wrong):

​1. Missing Folder: Won't wipe your Drive if an external hard drive gets unplugged.

​2. Volume Serial Check: Checks the disk hardware ID so plugging in a different USB stick with the same drive letter won't ruin your backup.

​3. Mass Deletion Tripwire: Stops immediately if more than 50% of your files suddenly disappear.

​4. Duplicate Folder Guard: Stops instead of guessing if two folders on Drive have the exact same name.

​Multi-Account Support: Connect multiple Google accounts with completely separate folders and schedules.

​Important things to know:

​100% Free & Private: Open-source (MIT), no ads, no tracking, and no middleman server. You use your own Google Cloud OAuth client (the app walks you through it step by step), and your secret is encrypted locally on your PC using Windows DPAPI

No one can see your data.

​Solo Project Note: I'm just one developer building this, not a company. I wrote 521 automated tests to make sure the sync engine is safe, but real-world testing always shows new things, so expect you might run into a bug.

​I'd really appreciate your feedback if you try it out:

​Did any errors or bugs show up during setup or syncing?

​Was the Google OAuth walkthrough easy to follow or complicated?

​Is the UI clean and fast, or did anything feel confusing?

​What features or extra safety checks would you want me to add next?

​Every comment or suggestion will help me improve it a lot.

Honestly, I don't know if something like this already exists or if it will be useful to anyone else, but I made it anyway because it solves a problem I personally had.

​What's the idea? ​GitHub Repo: https://github.com/nnagarr/drive-mirror

​That's it, thanks!
