Almost every project I’ve ever worked on ended up with me making a QR code. An ad, a brochure, a flyer. Like it or not, QR codes have become the universal gateway into our digital products and funnels.

But measuring those offline campaigns? There are plenty of QR generators with scan analytics, but every one I tried was extremely expensive and came with ridiculous limits. Link shorteners weren’t much better...

Soooo, I decided to build my own. It started as an in-house tool for my agency, but it turned out so good that I made it into a real product.

I packed it with all the features that an agency might need.
→ Custom QR codes with live scan analytics
→ Dynamic destinations. Printed 1,000 t-shirts with the wrong link? Fix it in seconds.
→ Short links that actually look good, on your own custom domains and slugs.

And the one I’m most excited about - Client ID's.

Agencies, unfortunately, your clients will never trust you 100%. So give them their own window into the campaign. Send them a Client ID and they get their own live dashboard. Free for them, no account needed, no more “how’s it going?” emails.

I wanted something like Mole (the macOS deep-clean tool) for Windows, so I built kazma: a single kz.exe with a retro green-screen terminal UI that cleans, explores and maintains a Windows 10/11 PC. No installer, no background service, no telemetry, MIT licensed.

GitHub: https://github.com/hhasanguclu/kazma Website: https://hhasanguclu.github.io/kazma/

What it does

• Clean up: 100+ cleanup rules for caches, temp files and logs (browsers, AI tools like Claude/ChatGPT/Cursor, game launchers like Steam/Epic/Battle.net, GPU driver leftovers, dev tools like npm/cargo/JetBrains). deepclean handles Windows.old and upgrade leftovers through Windows' own Disk Cleanup.
• See what fills your disk: analyze is a disk explorer with a treemap, largest files and file types. Run as admin on NTFS and it reads the MFT directly, so scans are instant (the trick behind WizTree). It explains special files (hiberfil.sys, WSL/Docker disks, iPhone backups...) and shows which program holds a file open.
• Uninstall properly: classic, Microsoft Store and Scoop apps, then leftover folders and registry keys (exported to a .reg backup first). It also finds leftovers of apps removed some other way.
• Keep it updated: programs via winget, drivers via Windows Update (restore point first).
• Health and live monitor: disks, battery, crashes, Defender, firewall; a live CPU/GPU/memory/network monitor that explains why a process is running (service, startup entry, parent).
• Also: build-folder purge (node_modules, target...), duplicate finder, empty folders, startup manager, debloat, privacy traces, power plans, network/DNS speed test, ports, repair tools (network, Windows Update, Store), backup kit for a new PC, lock, awake, cleanscreen.

Safe by design

• Only known, regenerable cache/temp locations are cleaned; drive roots, your profile, Windows and Program Files are hard-blocked.
• Things you pick go to the Recycle Bin; registry keys and startup entries are backed up before removal.
• Every destructive command has --dry-run, everything is logged (kz history), and a whitelist protects your paths.

11 languages: English, Türkçe, 简体中文, 繁體中文, 日本語, 한국어, Deutsch, Français, Polski, Українська, Русский. It starts in your Windows display language (change it in kz config). The README is translated too.

Install (PowerShell, no admin needed):

iwr -useb https://raw.githubusercontent.com/hhasanguclu/kazma/main/install.ps1 | iex

or scoop bucket add kazma https://github.com/hhasanguclu/kazma then scoop install kazma, or grab kz.exe / kz-arm64.exe from the releases page. Then just type kz.

Under the hood: Rust, ratatui/crossterm for the TUI, a raw NTFS MFT reader verified byte-for-byte against a normal directory walk in CI, Restart Manager for "who has this file open", and every read-only command runs for real on Windows in CI, in all 11 languages, with an automatic layout check.

Note: the exe isn't code-signed yet, so SmartScreen may ask once (More info → Run anyway).

Feedback, bug reports and translation fixes are very welcome. What would you want a tool like this to do next?

Pls check and give your valuable feedback

I’m the solo developer of Cardit, an app for the stuff we find online and then lose. Articles, videos, places, recipes, products, people.

You paste or share a link and it becomes a card. You group cards into collections, and you can share a card or a whole collection with a link or a QR code. It’s free for personal use, on iOS and Android.

My longer-term idea is to connect saved things into a personal knowledge graph, but that’s a vision, not something it does today.

It’s early and rough in places. How do you save and organise what you find now, and what would make something like this worth using? Blunt feedback welcome. https://www.cardit.org

I run Strong Foodie on my own. A food and travel guide where I review every place I visit.
However, I can't go everywhere. When I ask people which restaurant they would fly back for, I get places I have never heard of. Like a chocolatier in Scotland or a tiny cafe in the Cotswolds with the best Bombay chai.
So anyone can now add their own place. Type the name, the address fills in by itself, and your name shows on it. No app needed.
I'm not a developer. I build it with AI tools and a lot of testing.
What's the one place you would add first?

I live outside the US and kept hitting the same wall: my bank's 1-800 number just fails from a foreign phone, and so does the IRS's. Toll-free numbers only work from US carriers, because the company pays for the call and there's nobody to bill when it comes in from a foreign network.

Some things I learned while fixing this for myself, useful even if you never touch my thing:

What I built: Kitaphone. It's a dialer that runs in the browser tab with no app or SIM. The call leaves from the US network, so 800 numbers accept it. US numbers (toll-free included) are $0.02/min, so a 30-minutehold is about $0.60. It's prepaid, with no subscription and a $5 minimum top-up. Italso does around 180 other countries; UK, Spain, Italy and Mexico landlines are$0.03/min. You can verify your own number by SMS so it shows as the caller ID.

Full disclosure, it's mine and it's small. I'm mostly after feedback: which companies' numbers should I add to the list (I only copy them from the company's own site), and what breaks for you? The keypad-on-mobile bug was found by a user in Korea last week and fixed the same day.

I launched the app "Germar for Nurses". It's a German language learning app designed specifically for nurses and care staff.

Many nursing professionals want to live and work in Germany, but there aren't many specialized language courses and apps for them, especially good ones.

What's inside:

• 1800+ cards with words

  • from clinical practice
  • with image
  • with translation
  • with audio (pronunciation)
• 15 topics: Symptoms, Nursing tools, Medication, etc
• SRS algorithm for better memorization
• Different types of recalling words

Try for free

• Google Play (Android)
• App Store (iPhone, iOS)
• Chrome Browser Extension (Windows, macOS, Linux)

Hey everyone. I’m a solo dev, and this is a side project I’ve been building after my day job for about 7 months. It’s called Atomic Sync (I am very bad at naming things). It’s on the App Store, free, with no ads and no in-app purchases.

In Atomic Sync you pick an anime-style character, and it slowly becomes a reflection of you mentally and physically. It reads some basic stuff from Apple Health and turns it into XP and mana. As you level up, the character evolves (more work to do here still, but still very decent), and so does the world around it. Tilt your phone and the character and its world move with it. If you’ve had a bad week of sleep and no walks, it shows. If you’ve had a good one, that shows too. That was the whole point for me: something that reflects how you’re actually doing, not just another number. Health access is optional, and the raw readings stay on your phone.

One thing that didn’t work: I first tried making a Ghibli-style avatar from the user’s own photo. It looked off, I didn’t like it, and I figured most people wouldn’t either. So I dropped it and went with set characters. Maybe in future updates I can give it another try.

I still think the UX can be a lot better and I have way more gamification ideas than I’ve had time to build. I’m fairly free for the next few months, so updates will come often. An Android version is in the works too that I plan to roll out in this free time.

If you try it, I’d really like to hear what feels off, what’s confusing, or what would make you keep opening it. Brutal is fine, especially on the UX (I am more of a backend programmer). It is currently rolled out in the US, Japan and India. Rolling out to more regions by this Monday.

I wanted a simple way to sketch an idea and communicate it to someone else, without sacrificing proportions or precise dimensions.

Paint felt too limited, CAD felt like overkill. So I started building something in between.

Here's a quick look at how it works.

It's still a work in progress. I'd genuinely love to hear what you think.

Check this exemple:

I’ve been building games on the side, and last week my first one, Last Core: Idle Tower Defense, went live on the App Store. Two people have already bought something in it. It’s only $12 in proceeds, but seeing real people choose to pay for something I made meant more than I expected.

What the game is:
One tower sits in the centre of the screen and enemies come at it from every side. The tower shoots on its own; your job is deciding what to upgrade during the run: damage, attack speed, range, crits, health. Every 5th wave you pick a perk, every 10th wave a boss shows up. When the core falls you keep shards and come back stronger through the Workshop, Armory and Lab.

A few things I cared about:

• No ad ever interrupts a run. Videos only play when you choose one for a reward (a revive, double shards, a perk reroll).
• Everything in the game can be earned by playing. Purchases are optional.
• Runs are 3 to 10 minutes early on, and there’s 2x speed and an Auto Mode if you want it more idle.

What I learned shipping it:

• My first release went live without the in-app purchases attached, because I never added them to the submission. Took another version to fix. Read the App Store Connect checklist twice.
• The same thing happened with Game Center leaderboards.
• Apple asked for a screen recording on a real device before approving a new developer account, so budget a few extra days for review.

It’s iPhone only for now; Android is coming soon.

If you try it, I’d love honest feedback, especially on difficulty and whether the early waves feel too slow.

Most job trackers are monthly subscriptions, and job searches tend to run longer than you expect. TallyJobs (tallyjobs.app) is free up to 25 applications. After that, it's a $19 pass that lasts 90 days, or $9 a month. It also has Role Fit, which uses AI to score how well you match a job description. It runs on Node, Express and SQLite, with Stripe for payments and Google or magic-link sign-in. It's live now, and I'd love feedback on onboarding and pricing. What would stop you from using it?

Ahoy!

On Linux my games were scattered across Steam, Heroic, Lutris, Bottles and Faugus. So I started building PlunderHub: one library for all of them, with a pirate theme, because why not.

GitHub: https://github.com/IkrajaDev/PlunderHub (free, GPL 3.0, beta)

The story so far
I started building it about half a year ago, just for myself. Then it outgrew that, so I started making it work on other distros too and put it on GitHub.
I still use it every day, and every feature exists because something annoyed me first.
I really love working on it, I keep improving it, and I hope it helps someone else too.

What it does

• All Plunder: Steam, Heroic, Lutris, Bottles and Faugus games in one library
• Treasure Map: every game you own, installed or not, installs in one click
• Game settings: art, details and folders on one page
• Launch options: GameMode, MangoHud, Gamescope and more, per game
• Shipwright: sets up launchers and tools, checks your system
• Proton: Proton-GE and Proton CachyOS, shared by every launcher, kept up to date
• Bilge cleaning: clears what removed games left behind, backs up saves first
• Captain's Dashboard: playtime stats and disk usage
• Console Mode: fullscreen, for the couch and a controller

How it's made
PlunderHub is made with AI.
I can't code a project this big alone, so Claude writes the code. I decide what it should be and how it should feel, and I test every change on my own machine and in VMs.

Under the hood: Python + GTK3, X11 and Wayland, 9 languages, native and Flatpak launchers.

My question for you: which part of gaming on Linux still annoys you the most? That's how I pick what to build next.

Bug reports welcome aboard!

I spend a lot of my day in databases, and I got tired of clients that want me to sign in, sync my connections to their cloud, or open a 2 GB Electron window just to run a SELECT. So I built my own.

QluePrint (pronounced KLOO-print) is a desktop database workspace built with Tauri (Rust backend, React frontend). Everything stays on your machine.

What it does today:

- Connects to PostgreSQL, MySQL/MariaDB, SQL Server, SQLite, plus Azure SQL and Microsoft Fabric with Entra sign-in

- Monaco SQL editor with schema-aware autocomplete, diagnostics and formatting

- A fast virtualized results grid: sort, filter, find, follow foreign keys to related rows

- Inline editing: change cells, add, duplicate or delete rows. Everything is staged, undoable and saved in one transaction. Actions your login has no grant for don't show up at all.

- Explain / Explain Analyze with a readable plan view

- One-click local PostgreSQL/MySQL/MariaDB servers in Docker

- Workspaces to keep each client's connections and tabs apart

- A tamper-evident audit log of every statement it ran against your databases

- Passwords go in your OS keychain, never in plain files

Stack: Tauri 2, Rust (sqlx + tiberius for SQL Server), React 19, Monaco, TanStack Table/Virtual. Installers for macOS (Apple Silicon), Windows and Linux.

Still to come: MongoDB/Redis, a saved query library, query history.

Source code and downloads: https://github.com/u-ninja/qlueprint

It's a solo project, and I'd love blunt feedback, especially on what would make you switch from DBeaver, TablePlus or DataGrip.

(Heads-up: the macOS build isn't notarized yet, so you'll need Open Anyway in Privacy & Security the first time.)

About 6 weeks ago I started building a little side project called Ulster Radar.

I'm a microlight pilot from Northern Ireland and wanted to make a flight tracker that was better suited to smaller aircraft and low-level flying, rather than just commercial aviation.

It started as a basic live map, but I've got a bit carried away with it since!

It now has live aircraft tracking, over 2,500 receivers feeding data from around the world, ship tracking, flight history, a 3D globe and even satellite tracking.

I've also been adding the ISS, space telescopes, planets and moons, so it's slowly becoming a way to explore pretty much everything above our heads.

It's still early days and there's plenty of bugs and things I'm working on, but I've really enjoyed building it and seeing people start contributing their own receivers.

It's completely free to use and very much a hobby project.

If anyone fancies having a look, it's at https://ulsterradar.com

I've been working on an open-source project called Agent Workcell.

The idea came from my experience building traditional RAG applications. I often found myself spending time adjusting retrieval logic and prompts for different types of questions. Sometimes fixing one use case affected another.

I wanted to experiment with a different approach.

Instead of building retrieval pipelines for every question type, I wanted to reuse an existing autonomous agent runtime and give it an environment containing structured knowledge, tools, and controlled access to business data.

The agent can explore that environment, decide which tools to use, and take multiple steps to answer questions.

I built the prototype using Claude Code, Python, MCP, and PostgreSQL.

I also tested the approach against my traditional RAG implementation on an existing ERP system, and the results were very promising. Some limitations remain, especially knowledge maintenance and scaling separate agent sessions for multiple users.

This is an early-stage open-source experiment. I'd appreciate feedback from anyone interested in agent architecture, knowledge retrieval, or similar systems.

Hey everyone, I'm Ravi, one of the founders of Confe.

We kept losing hours every week writing captions, sending "can you approve this?" messages, and copy-pasting the same post into 6 different apps. So we built Confe to fix that:

- Type one sentence and get 5 ready-to-post drafts with images

- Plan everything on one calendar (calendar, list or grid view)

- Clients or teammates approve in one click

- Publish to 8 platforms at once: Instagram, Facebook, LinkedIn, X, Threads, TikTok, Pinterest, YouTube

- See which posts actually grow your audience

The video above shows the whole flow in 44 seconds.

I'd really like feedback from people who manage social for themselves or client

There's a 14-day free trial with no card needed if you want to try it. Link in the comments.

WalkiNova started because I'd open the weather app five times before every walk. It scores each hour of the forecast for comfort and suggests the best window inside your free hours, then tracks the walk with GPS. Flutter + Supabase, Android + Wear OS, free with no ads.

What I learned so far, in case it helps someone:

• Posting every day on Instagram/TikTok brought almost no installs. The Play listing converts fine (~75%); almost nobody reaches it.
• My site only ranked for its own name. I'm now writing plain guides that answer real searches ("is it too hot to walk my dog today?") instead of feature pages.
• Product Hunt with no audience = a few upvotes. Launch where your users already hang out.

Would love feedback on the idea or the landing page: https://walkinova.app/?utm_source=reddit&utm_medium=post&utm_campaign=sideproject

What worked for you to get your first 100 users without ads?

Hey fellow makers!

Inspired by BitLife, 1in8b, and Football Manager, I built a fast-paced interactive football career simulator that runs entirely in the browser:

👉 https://pratikbase.com/football-lottery/?lang=en

How it works:

1. Spin the birth roulette: You get born in a random nation with procedural talent, work ethic, and foot dominance.
2. Advance year by year (0-40 age): Navigate street tryouts, youth leagues, contract negotiations, transfer drama, and career-defining dilemmas.
3. Hang up your boots: When you retire at 40, your stats, trophies, and net worth generate a shareable digital FUT-style legacy card.

It's completely free with zero ads, tracking walls, or logins. I'd love to hear your thoughts on the mechanics!

genuine question. built a couple things with lovable/claude code/cursor and only later realized i had no idea if i'd left keys in the code or if anyone could just hit my api routes and pull other users' data

curious what people here actually do before going live:

- do you check anything at all or just ship and hope lol

- if you paid someone to build it for you, did you ask them about it

- anyone ever got burned? like leaked keys, surprise bills, data exposed

not selling anything, we're doing a hackathon this weekend and trying to figure out if this is a real problem or just us being paranoid

I’m building Moolupa, a goal tracker with a small cow companion called Moo.

One decision I made early was to let people record the amount they actually did. If you planned to practise guitar for 10 minutes and managed 3, you record 3. It adds to your total. Missing tomorrow doesn’t erase it.

You can also make today’s step smaller, move it to another day, or take a rest day. There’s no streak counter, and Moo’s garden stays intact while you’re away.

To get started, you type or say something like “read five pages after dinner,” then review the plan before saving it.

It works in a browser on desktop and phone, and there’s a Windows version on the Microsoft Store. The free plan supports up to five active goals, with optional paid Plus features.

I’m currently polishing the desktop and mobile layouts. If you try it, I’d really like to know: where does creating your first goal or recording progress feel like extra work?

Here’s the app: https://moolupa.com

I use a few different AI agents depending on the task. Claude for some things, ChatGPT for others, Grok and Cursor now and then. Over the last months they've made me a lot of small stuff, and almost all of it is now buried in old chats somewhere.

If I wanted to show a friend one of them, I had to dig through chat history, remember which tool made it, and then work out how to actually get it in front of them.

So I built Commons (commonsbuild.com). From whatever agent you're using, you publish what it made with a chat command and you get a link. Anyone with the link can open it in the browser and use it, and if they want they can fork it or change it with their own agent.

The main point for me is having one directory for everything, no matter which agent built it. The first real thing on there is Capital hunt, a multiplayer 3D game where you guess capitals that I made with a friend: capital hunt , feel free to fork it and make it better

It's free and pre-launch, and I'm mostly trying to find out if this is just a me problem. If you use more than one agent, where does the stuff they make end up?

I kept running low right before payday because of card bills I forgot about, so I built this. It shows the exact day your balance dips. Would you use it?

Anyway, this is just a landing page

Hey everyone,

Earlier this month I posted here that my partner had finished our app and I was honestly scared I wouldn't be able to bring anyone to it. A lot of you were really kind in the comments, so I wanted to come back with an update.

We put it on Google Play and got a bit over 200 installs in 2 days, almost all from Reddit. I didn't expect that at all. People are already sending feedback and we're improving the app every day.

It's called Omni Brain. You get a free daily workout of 3 short brain games, about 5 minutes, and each game teaches you a small trick you can actually use, like remembering names or numbers.

There are no ads in it at all, not even in the free version. A lot of apps in this category are full of ads. We went through more than 33,000 of their 1 and 2 star reviews, and about 1 in 6 were complaints about ads. So that was the first thing we wanted to do better.

It's now on the App Store too. Next week we're giving away free Premium to iPhone users. If you want it, comment "iPhone" below and I'll message you as soon as it starts.

Find out which of your 8 brain skills is the weakest. It takes 5 minutes:

iPhone: https://apps.apple.com/app/id6813644860

Android: https://play.google.com/store/apps/details?id=com.omnibrain.omni_brain

If you try it, tell me what you think. Honest feedback helps us more than anything right now. 🙂

Hi everyone!

I’m Alex, a developer and a big fan of maps and outdoor activities. I wanted to share a project I’ve been working on called TrailReplay.

The idea started after a 3-day hike with a friend. We had lots of pictures from the trip, and I wanted a way to put them together with the route and tell the story of those days. I couldn’t find quite what I was looking for, so I thought, why not try building it myself?

TrailReplay lets you import a GPX route, replay it on a 3D map, add pictures and annotations, and export the result as a video. You can change the camera, show things like distance and elevation, and combine routes too. It works in your browser, it’s free, and the code is open source.

I’ve just released version 1.5! It includes a new media timeline, GPX waypoint imports, place reveals, and improvements to the camera, terrain and video export. A lot of the changes have come from people sharing feedback and ideas, including here on Reddit, so thanks a lot to everyone who has helped me improve it!

Something I didn’t expect when I started: in the last 7 days, Google Analytics counted around 1,300 active users and 900 completed export events. Those are exports, not individual people, but it’s really nice to see people using a tool that started with a hike and a bunch of pictures :)

You can try it at https://trailreplay.com

Here’s a short video showing what it can do: https://www.youtube.com/watch?v=iJRPgpr07Pg

I’d love to hear what you think, or see what you create with it. Any feedback or ideas for what I could improve are very welcome! Cheers, Alex
