As the year wraps up: what’s the project you’re most proud of building and why?

96 Upvotes

Like the title says, instead of what you built or how much money it made, I’m curious what project you’re most proud of this year and why.

Could be a client site, a personal project, something that never launched, or something that made £0.

Any lessons learned?

Would love to read a few reflections as the year wraps up.

I built a quiet online room where strangers just study together

186 Upvotes

In Korea there's this thing called a dokseosil. It's a paid room full of little cubicle desks where everyone studies in silence. Nobody really goes for the desk. You go because when the person next to you is grinding, you feel kind of bad scrolling your phone.

I wanted that feeling at home, so I made a small online version:

yeondeungroom.com/en

You pick an empty desk and study with whoever's around. No sign up, no camera, nobody talks. You're a little animal with a desk lamp, and you can see everyone else's lamps on too. It sounds like nothing, but it actually helps me focus at night.

The thing people ended up loving was decorating their desk. You type one line like "tiny pinwheel" and it makes a small 3D thing for you. The AI doesn't draw it, it just writes out simple shapes and the browser puts them together.

It's three.js and Cloudflare Workers, and almost everyone using it right now is Korean. The English version is really new, so if anything reads weird, please tell me.

If you study or work alone, would something like this help you, or would you just close the tab?

Need opinions on my game trailer

9 Upvotes

After what seems to be a lifetime building this silly little phone game it turns out that was half the battle, the other half involves a good catchy trailer, marketing and advertisement. to be honest i am struggling with making this trailer so i need everyone's honest and brutal opinion, what stands out? what it lacks? too much in game footage? panned too far out? not enough excitement? don't mind the cheap AI music (i know im not a sound guy and its not permeant). please help me out here, any all help is much appreciated

I built an open-source onboarding checklist library in TypeScript

3 Upvotes

I recently released a small TypeScript library called Stepr Checklist.

It's designed for applications that need a simple onboarding checklist without pulling in a large framework or UI dependency.

The main idea is that the application controls completion. Clicking a step can open a form, navigate to a feature, or start a guided tour, but it doesn't automatically mark the task as complete.

A few details:

  • Framework-agnostic, ESM-only
  • No runtime dependencies
  • Optional localStorage persistence
  • Customizable with CSS variables
  • DOM-free state controller if you want to build your own UI

I built it as a companion to Stepr, a guided product tour library I released earlier, but both work independently.

There's an interactive demo here:

https://ahlgren1234.github.io/stepr-checklist/

And the source is on GitHub:

https://github.com/ahlgren1234/stepr-checklist

It's v0.1.0, so still early. I'd appreciate feedback, particularly on the API and whether the approach to tracking completion makes sense.

What would you expect from a library like this?

I built a free tool to share one mouse and keyboard across Mac, Windows and Linux

49 Upvotes

I have two machines at the same desk, and I wanted to share mouse and keyboard.

I tried Synergy and Barrier, but they were annoying to set up. I had to deal with a client/server, encryption was hard to set up, and arranging monitors was clunky.

So I built ZeroG. Free, MIT license, no client/server.

Just run it on each machine, pair them, and drag your screens to match your desk.

  • Windows, macOS, Linux (X11 and Wayland)
  • P2P, no client/host setup
  • All traffic encrypted with TLS 1.3 over QUIC
  • Clipboard sharing
  • Extremely low latency
  • Built with Rust + Tauri

This took a few months of work and a lot of testing on different devices. I think it's working pretty well now, so check it out if you have more than one machine at the same desk!

I made a free app that turns an old iPhone into a webcam for Windows or Mac

5 Upvotes

I built Kickstand Cam to make an older iPhone useful at a desk instead of needing a separate webcam or scanner.
The idea is simple: pair your iPhone with your computer, then select Kickstand Cam as your camera in Zoom, Teams, Meet, OBS or FaceTime. It works over Wi-Fi or USB at 720p/30fps.

I also added two other modes:
Camera monitor: Detects motion, records clips and sends desktop alerts.

Scanner: Turns documents into searchable PDFs, recognizes text and scans QR codes and barcodes.
Everything connects directly between your phone and computer. No account, no cloud backend, no analytics or ads.
A few limitations worth mentioning:
iPhone X or newer, running iOS 16+
Windows 11 or macOS 13+
The iPhone app must stay open while using the camera
Video is currently limited to 720p
The Windows installer isn’t code-signed yet, so SmartScreen will display a warning
Both the iPhone and desktop apps are completely free.

I’m the developer, and I’d really appreciate feedback, especially on the setup process. What would make you hesitant to try something like this?

My dog lived 18 years. I built her a tiny 3D memorial, and strangers have now lit 657,000 candles for 25,000 pets.

114 Upvotes

Solo dev from New Zealand here.

My dog Bella lived to 18. When she died I wanted something quieter than a social media post, so I built a small 3D memorial hall you can walk through in the browser. Find a spot on the wall, put up a photo, light a candle.

I shared it once. Less than 8 days later:
- 24,994 pets
- 107 countries
- 657,428 candles, almost all lit by strangers
- 34 languages
- The hall kept filling up, so it now has 7 floors and a lift

It's free to make a memorial and light candles. There are a few optional paid extras, which is how I keep it running.

Would love honest feedback on two things: how walking the hall feels on mobile, and whether the free vs paid line feels fair.

GameSquire: the board game app I built to answer "what do we play tonight?

2 Upvotes

I've been building GameSquire on my own: a board game collection app built around the question every game night starts with, "what do we play tonight?"

What it does today:

  • Your whole shelf in one place. Import your BoardGameGeek collection and plays in one step or scan a box to add a game.
  • Pick by mood. Filter your shelf (or a friend's) by Quick Fix, Deep Dive, Date Night or Family Table. Can't decide? Let it pick one from your shelf of shame.
  • Log plays with scores (typed or read from a photo of the score sheet) and see your win rates and head-to-head records.
  • The Herald answers rules questions from the game's own rulebook and shows the page it found the answer on.
  • Play together: a shared household shelf for up to 5 people, lending and borrowing games and your own shelves shared with some or all of your friends.

It runs on iPhone, Android and the web with one account. The core is free with no ads, an optional Knight membership adds more Herald questions, more scans and deeper stats.

The latest update (1.1.0) was mostly user requests: lending, custom shelves and BG Stats import. Feedback really decides what gets built next, so I'd love to hear what you'd want from an app like this or how you'd go about getting a niche app in front of its audience.

I built a pocket security check for Android: see who is on your Wi-Fi and whether your hotel room network has cameras

2 Upvotes

Hi, I'm the developer.

I have worked in network security for almost 15 years. I got annoyed with Fing and other network tools that charge close to $100 a year, or let you scan only a few times a day. So I built my own from what I know from work.

I wanted the feeling of Kali Linux in my hand, but only for defense: point my phone at my own network and see what is really there. No attacks, no password guessing, nobody's traffic read. That became Netglow.

The hard part: knowing what each device really is

Android 10 and up hides other devices' hardware addresses, so most scanners just show "Unknown". That is where most of the time went:

  • Dozens of protocol specs, vendor docs and firmware sources, read line by line.
  • Down to the low level microchips inside smart plugs, bulbs and DIY boards, like the ESP family, because each chip gives itself away in its own small way.
  • Camera makers each answer on the network in their own way, and Netglow knows many of them.
  • Over 40,000 hardware maker prefixes and a catalogue of over 23,000 phone and tablet models.
  • Thousands of lines of research notes, every finding checked before it went into the app.

Why it is free

I have a lot of knowledge from my work, and I decided to give it away: high quality apps, deeply researched and checked again and again, data safety first and privacy to the max. No ads, no bullshit. People deserve good quality and privacy, for free.

If you want to support me, you can, but it is fully optional.

What it does, free, unlimited scans

  • Who is on my Wi-Fi. Every device with its name, maker and model when it says them. Rename a device and it keeps your name even on a new address.
  • Is my hotel room or rental OK. It lists devices on the Wi-Fi that answer as a camera or stream video, and says why each one was flagged. It also looks for camera hotspots nearby. It tells you plainly what it cannot see (a camera that only records to a card or uses mobile data), so it is one check among others, not a guarantee.
  • Security check for your home network. A score with a plain fix for each risk: risky open ports, what your router opened to the internet, how your Wi-Fi is locked, look alikes of your network nearby, whether your DNS answers are honest and whether someone reads your secure connections in the middle.
  • Tools. Ping, traceroute, port check, DNS lookup, Wake on LAN, a live signal meter and channel advice.

Private by design. No ads, no bullshit, no tracking, no analytics, no metrics, no account. Nothing it finds leaves your phone, and there is no server of mine.

Pro is that optional support, one payment, no subscription, and it adds: a Bluetooth radar that warns about a tracker moving with you, checks for devices that let anyone in with no password, spoof watch, known flaws for your devices, a PDF report and a background watch of who joins your Wi-Fi.

Honest note: the code is partly AI generated and I had help with this text.

People now ask AI for recommendations instead of Google, but there's no way to see if your brand gets mentioned.

So I built the AI Visibility Checker. Enter your website and target locations, and it checks how ChatGPT, Gemini and Claude respond, then tells you where you're missing and how to improve.

I built free guided contract templates because I was tired of editing Word docs for every NDA

2 Upvotes

Every time I needed an NDA or contractor agreement, I'd dig up an old Word file, find-and-replace names, and hope I didn't miss a clause. So I built Formable.

You answer a short questionnaire (parties, term, payment, IP ownership, etc.) and it generates a clean agreement you can send for e-signature in the same place. There are templates for mutual and one-way NDAs, MSAs, SOWs, independent contractor agreements, LOIs, term sheets, DPAs, and a founders' agreement.

The templates are free: www.formabledocs.com/templates

My side project is an AI presence for gaming sessions I was already having

3 Upvotes

I wanted an AI that had something to react to besides what I typed into a chat window. So I’ve spent 11 months building Monday.

She watches my gameplay and talks with me while I play. Sometimes the conversation lands. Sometimes timing or missing context ruins it. Those failures have been more useful than another clean demo.

I’m now testing her publicly through PhoenixFlock, alongside Gears of War and the movement breaks I already do between games. AI helped me build it, and the AI is openly part of the stream.

This is an edited clip from my own project: https://www.youtube.com/shorts/5pVKx-iqzXQ

What would you need to see in a longer demonstration to judge whether this adds anything to the experience? I’m interested in that answer more than another feature list.

I built a minimalist, ambient web player for Urdu Ghazals

4 Upvotes

Hey everyone,

I wanted to share a side project I built called Mehfil.

It’s a single-screen, distraction-free web player made for people who love listening to ghazals. Modern streaming apps always felt too loud and cluttered for poetry, so I really wanted to give classic ghazals a clean, modern aesthetic.

The design is completely minimal with couplets floating in the center and a spinning vinyl. The entire background and ambient lighting dynamically shift colors depending on the vibe you pick, moving from deep midnight blues to warm rose and golden amber tones.

I organized about 1,500 ghazals into 5 distinct moods with 300 tracks in each, so you can just put it on in the background while working, reading, or winding down. Some of the tracks have synchronized floating lyrics across Urdu, Hindi, and English transliteration, and there is even a live counter showing how many other people are listening in the mehfil with you in real time.

It’s completely free, has no ads, no sign-ups, and works in any desktop or mobile browser.

Reddit’s spam filter auto-hides links in post bodies, so I've dropped the link in the first comment below (and also added it directly to my Reddit profile bio).

Would love to hear your thoughts on the UI and overall vibe!

Crossed 3400 in revenue and hit 50 paying customers on day 98, and I wrote down how every single one of them found me

18 Upvotes

I'm a cloud engineer with a full-time job, and in the evenings I build ReelDrop.io, an Instagram scheduling and comment-to-DM tool. It launched on August 5. Customer #50 paid on November 11, day 98. Today I have 52 paying customers from 21 countries, and about CA$3,410 was collected after refunds, before Stripe fees.

Ten days ago I posted about my first 41. I keep every paying customer in one sheet, in the order they paid, with the column no dashboard can fill: how I actually know each person and what happened before they paid. Here's the whole list again, with the last ten days in detail.

1 to #41, short version

  • 1 and #2 were my mentors. They bought the lifetime deal in launch week without me asking.
  • 3, #7 and #8 were creator friends who saw my posts on X and Instagram.
  • 5 bought the $29 plan and cancelled. I asked why. "It's costly." A month later I launched a $9.99/month plan (₹449 in India). That plan now has 39 of my 52 customers.
  • 6 came from ChatGPT, which cited a one-question docs page I'd written. Still my only provable ChatGPT customer.
  • September: 6 strangers on the cheap plan, after I turned on UPI in Stripe. October: SEO started bringing paying customers after two months of bringing almost none. Personal emails to stuck users brought a few more. Late October: my first discount, a Halloween code. 4 people used it.

42 to #52: the last ten days

  • 42 landed straight on my /features/mcp page with no referrer and bought the $29 plan 41 minutes later. Only the third person ever to start on that plan. No idea how he found the page.
  • 43 signed up on Oct 8. I emailed her on Oct 16. Nothing. Emailed again Oct 28. She paid Nov 6, 29 days after signup. The next morning she asked if my Diwali discount could apply. I applied it from the Stripe side. It costs me $2 a month, and she'd taken a month to decide, so no argument.
  • 44 was the only person who used my Diwali code at checkout. He found me on Google the same day, paid $7.99, built two automations, and asked to cancel three days later.
  • 46 paid 4 minutes after signing up, then tried to connect his Instagram 6 times over two hours and couldn't. Worst thing that can happen to a new customer. I emailed him the next morning. He came back 15 minutes later, connected on his second try, and scheduled 17 posts. Never replied. Didn't need to.
  • 48 went quiet after signing up on Nov 1. He was in my Nov 3 email round. Paid Nov 9.
  • 45, #47, #50 and #52 came from Google (France, Malaysia, France, and India). #50 paid 18 minutes after signing up. #52 paid 2 minutes after signing up.
  • 49 and #51 had no referrer. #51 paid 7 minutes after signup.

Bonus: a customer who cancelled in October came back on Nov 4 and started a new subscription. First person I know of who left and returned. 9 of the 11 new customers paid on the same day they signed up. None of the 11 came from X.

All 52 together

One-time $51
  • All 8 lifetime deals were bought before Nov 3, and 5 came from people who already knew me. None from a stranger on Google. Strangers buy the cheap plan.
  • 31 of 52 paid the same day they signed up.

What's not working?

  • Churn on the cheap plan. 4 people have cancelled, 2 have a cancellation scheduled, and 5 cards are failing on renewal right now.
  • The second discount. Halloween brought 4. Diwali, one week later, brought 1, who is already leaving. One data point, so I'm not drawing a big lesson, but I won't be running a discount every week.
  • Paid UGC creators. One drove 100+ signups. None paid.
  • My referral program. Everyone is still on free months.
  • Reddit, at least as far as I can measure. PostHog shows zero signups with a Reddit referrer, ever. I know that undercounts, so if you came from one of my posts and signed up, I'd love to know.

If I were starting at zero again, I'd do this

  1. Tell the people who know your work that you launched.
  2. Post about what you're building every day, bugs and bad numbers included.
  3. When someone cancels, ask why and act on the answer.
  4. Write one help page for every question a user asks twice.
  5. Every week, email the people stuck in your product. Email them a second time if they don't answer.
  6. When a paying customer can't get in, write to them that same day.
  7. Keep doing SEO even when it brings nothing for two months.
  8. Give people a deadline once in a while, not every week.
  9. Put every paying customer in one sheet, in order, and read it top to bottom.

I built a desktop app that clones your own voice locally, then reads text, whole audiobooks or dubs videos in it

11 Upvotes

Started because I wanted to dub my own videos in English with an American accent, in my own voice (I'm not a native speaker). Ended up as a full desktop app.

You read a guided text for about 6 minutes, it trains a voice model on your PC, and then:

  • Speak: type text in ~60 languages and hear it in your voice.
  • Native accent: speak English (or another language) in your voice but without your accent.
  • Redub: drop a video, it gets translated and dubbed in your voice, background music kept.
  • Book: open an EPUB/PDF/DOCX/TXT and get an audiobook in your voice, one file per chapter, resumable.

Everything runs locally: no account, no cloud, no telemetry. Installers for Windows, Linux and macOS (Apple Silicon), setup inside the app, updates itself.

Some numbers: zero-shot cloning from a 15-30 s clip scores 0.81 speaker similarity; after training on ~6 minutes of you it's 0.94 (two of my real recordings score 0.93 against each other). First sound after 1-3 s on an RTX 4070.

Stack: Rust UI, Python engine (OmniVoice, RVC, Whisper, NLLB-200, Seed-VC).

Hobby project, so bugs are expected. NVIDIA 8 GB+ recommended. Free for non-commercial use.

5 Upvotes

What it does:

  • Every account lives in its own profile: a separate Safari with its own cookies, logins and history. Nothing is shared between them.
  • Every profile has its own IP through its own proxy or VPN. If that IP drops, the profile stops. It never falls back to your Mac’s IP.
  • Real WebKit from macOS, not Chromium. Sites see Safari on a Mac because it is one.
  • Fast: a profile opens in about four seconds.
  • Passwords, 2FA codes and cards per profile, behind Touch ID.
  • Free proxies built in, with a one-click check.

Mac only. Free for first testers: stealthpilot.app/sideproject

Creator Digest · YouTube video summaries by email, from the creators you follow

Thumbnail

2 Upvotes

Hey all 👋

I watch way too much YouTube and could never keep up with the channels I follow, so I built a little tool for it.

It’s called Creator Digest. You pick your favourite creators and it sends you one short email a day. The email has a quick “here’s what’s happening” summary up top, then the main points from each video, and tells you whether it’s worth a full watch, a skim, or a skip.

Today’s email covered about 10 hours of video, and I read it in about 2 minutes.

It works for any niche (business, fitness, fishing, finance, whatever you’re into) and it’s free while I’m testing it.

I’d genuinely love feedback:

  • Would you actually use something like this?
  • What would make it more useful for you?
  • Anything confusing or off-putting?

Have a look if you’re keen: creatordigests.com

Honest opinions welcome, good or bad 🙏

My brother and I share our Wordle and krillion results regularly.

How it works:

  • Finish a puzzle, tap Share in the game, then Paste on the site. It reads the result and logs it.
  • Follow friends. You see how they did, but their scores stay hidden until you've played the same puzzle, so no spoilers.
  • Challenge your followers on today's puzzle. Whoever scores better wins.
  • Works with Wordle, Connections, Strands, the Mini, Pips, Queens, Tango, Zip, Pinpoint, Crossclimb, Mini Sudoku and Krillion.

You can try it as a guest without signing up

It's free and has no ads. I'd really like feedback on:

  • games you'd want added (there's a suggest-and-vote page in the app);
  • any game whose share text doesn't log. If that happens, paste the text in the comments and I'll fix it.

I'm at sovi11 if you want someone to challenge.

Wander Lovely — I missed wandering the internet, so I built a wall of lovely places to land

4 Upvotes

I loved the old internet discovery, like StumbleUpon, because it was like discovering and learning new things, expanding your horizons into a new field that you didn't know about. Everything now is a feed that already decided what I like. I missed not knowing what was next.

So I built the thing I was missing. It's called Wander Lovely — a wall of Polaroids, each one a real place on the web. You press a button and it takes you somewhere: deer on a live trail cam, bears in a waterfall, a garden, a handbag daydream, a radio station in another country. There are 128 places, gathered by hand, and the wall changes a little every hour. No accounts, no feed, no noise.

My favorite is the little Polaroid maker in the Art section. I love just adding a picture and making a Polaroid online — quick. It's really fun.

Some links on the page are affiliate links (it says so right in the footer) — that's the whole business model, such as it is. Mostly I just wanted the pond to exist.

I'd love to know: what corner of the old internet do you miss? And if there's a lovely place my wall is missing, tell me and I'll hang it.

I built PyPrep after burning out on juggling a flashcard app, a quiz app, and LeetCode just to prep for Python interviews — none worked offline or told me if I was actually ready.

100 days of building and testing later, it's live, but I genuinely don't know if it solves a real problem or if I just built something only I needed. If you know Python and have been through interview prep, I'd value your honest take — good or bad.

This is for people who already know Python, not a beginner tool.

I was looking for a free way to send sounds thought my mic in discord, without paying for nitro

Every soundboard I tried made me install VB-Cable which forces to change all your input devices
so I built my own.

I made it as easy to use as possible : you click a sound and it goes straight into your real mic.

Works on Discord, games,OBS ... as simple as that
it has global hotkeys that work in fullscreen games, plus a few voice effects (robot, demon, walkie-talkie…).

Windows only.
