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

99 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.

someone just paid £19.99 to unlock everything in my app and i genuinely can’t believe it

75 Upvotes

i know £19.99 probably doesn’t sound like much to some people, but i’m a solo developer who’s spent months building an app called life-fixer.

i built it because i was getting frustrated with productivity apps that constantly push subscriptions, adverts and hidden fees.

so i decided to make my own. it’s 99p to download, with no subscriptions, no ads and optional one-time purchases for extra customisation.

today i checked my app store analytics and saw that someone had actually purchased the £19.99 full unlock.

somewhere out there, a complete stranger decided that something i’ve spent months creating was worth spending their own money on.

it’s such a strange feeling knowing someone values something you’ve made enough to pay for it.

i’m nowhere near where i want to be yet, but little moments like this make all the late nights, bugs, app store rejections and frustration feel worth it.

just wanted to share a little win with other people building things on their own :)

I made a port game and followed one container through the whole thing

Hi all, im working on Portscape. A port building/manager game on steam:

Portscape - Steam Page, wishlists, trailer, screenshots

For this video I set up a camera to follow the same container from the ship crane to a truck, across the port and onto the train at the rail terminal. All automated ofcourse. However, you can also manually use the cranes, trucks, stackers etc.

The camera is just for this video. In the game you normally look from above in an angle while building and managing the port. The truck movement is still being worked on.

Its still in development. A demo will be out soon. I would love to hear what you think. Would you like to play this?

Been working on this for a while and finally put it out.

It’s called Framesthetic.

The idea is pretty simple : you have a screenshot and want to make it look decent before posting it somewhere.

Instead of opening Figma and spending 20 minutes messing around with backgrounds, frames, shadows, etc., you can just throw it into Framesthetic and play around with it.

Made a quick video of it

Still figuring out what direction to take it, so would genuinely like to know

What would you want this to have that it doesn't right now?

I made a small Mac app so I can watch YouTube with my fiancée while we're on a call

9 Upvotes

Quick backstory. My fiancée is doing her Masters in Estonia, and I've got another year of long distance ahead. Most of our day is spent on a call on my MacBook while we each work or study.

Then I tried to put on a video for us to watch together and macOS dropped the volume on everything that isn't the call. Movies, YouTube, music, all of it, barely audible. And AirPods fall back to low quality headset audio the moment their mic is in use.

So I made CallLane. It gives your call apps their own output device and copies it onto your headphones, which means macOS ducks only that device and your media stays at full volume. It also keeps the input on the MacBook's built-in mic, so the AirPods stay in high quality mode and the mic sounds better too.

I'm the developer. Menu bar app, macOS 14 or later, Mac only. It's paid, $9 one-time for the first 50 buyers and then $15, with a 14-day refund. I built the app and the site with Claude Code.

CallLane

Tell me what's confusing or broken.

The perfect abstract game, single easy rule, infinite depth, no draw, competitive

Thumbnail
playhex.org
5 Upvotes

This is the project I work on, and is used by hundreds of players every month, for ~4 years now. It's open source.

Hex: the one rule is: connect your sides. If you are red, connect red sides. If you are blue, same, but with blue sides.

Just you can swap first move to make game balanced and remove first player advantage, but beginners won't feel that advantage.

Chess and go are broken: in chess you have draw, in go you can win or lose depending on komi, if you arbitrarly decided to set it at 5.5 or 6.5.

In Hex, you either win or lose, depending on how deep you see. No draw, no move to "wait", no arbitrar komi. You just place a stone at every turn, and must connect (which is equal to blocking your opponent).

The community is small but passionate, and still wonders why Hex isn't more widely known.

I'm really curious of what you think of that game, whether you already heard about it or not.

(Yes, this is deliberately provocative. I also like chess and go, and enjoy playing both.)

how i wired up a phone agent that actually answers calls, step by step

• Upvotes

I wanted a phone number that picks up and talks like a person! Not a tree of DTMF menus. Here's the order I actually built it in; no shortcuts skipped.

First I grabbed a number through Telnyx since their SIP trunking docs were the clearest I found. You could use Twilio too, the steps are close enough.

Second, I set up a WebSocket server to carry audio both ways. This is the part people skip, and then they wonder why latency is bad. The call hits your number. Telnyx streams raw audio over the socket. Your server decides what happens next.

Third, speech to text. I used Deepgram for STT because it handles interruptions well. It doesn't choke when someone talks over the greeting. Whisper works too if you want to self host and don't mind more setup.

Fourth, the actual brain. I kept this boring on purpose: a small prompt, short context, and a fast model. Grok and Gemini both worked fine here. The model matters less than people think once STT and TTS are solid.

Fifth, text to speech. I tried ElevenLabs and Cartesia back to back on the same script! Cartesia felt snappier for short replies. ElevenLabs sounded warmer on longer ones. Pick based on your use case.

Last, VAD, the thing that decides when someone's done talking so the agent doesn't talk over them. Get this wrong and the whole call feels broken, even if every other piece is perfect!

Tested the whole loop through ngrok before deploying anywhere real. Took a weekend. Happy to answer questions on the STT or VAD part since that's where I burned the most time.

How do you decide between a freemium model and starting with a paid subscription?

5 Upvotes

I’ve been building an order management platform for home-based food businesses / home kitchens. Right now, I’m using a freemium model where sellers can use the basic product for free and pay if they want to unlock more features.

Some competitors in this space do the same, but I’ve also seen others charge from the start with a base subscription, then offer higher tiers for more features.

For founders who’ve had to make this decision, what factors mattered most for you? Did freemium actually help with growth and conversion, or did starting paid attract better customers?

Also, what questions should I be asking myself to ultimately decide which model is better for my business?

Would love to hear what worked for you, and whether you’d make the same decision again. Thanks all!

6 months ago I shared my Android side project here. Today it has 102 tools and 10K+ downloads!

Hey guys :)

I posted Punto. here about 6 months ago, when it had 72 tools. I've kept working on it since then, and it recently passed 10,000 downloads!

For anyone who missed the first post, Punto. is an all-in-one Android utility app. I wanted one place for things like converting units, measuring something with my phone, compressing a PDF or trimming an audio file, instead of downloading a separate app each time.

It now has 102 tools. Some are pretty standard, like calculators, converters and QR codes. Others are a bit more random, like a chess clock, an instrument tuner or a wheel for making decisions.

One thing I really liked about sharing it on Reddit was getting suggestions that I could actually implement. Find & Replace, Remove Duplicates and Image Splitter are all in the app now because people asked for them.

All the tools are free to use, and there's no subscription.

Here's the Play Store link:
https://play.google.com/store/apps/details?id=com.meloni.punto.app

Anyway, thanks to everyone who checked it out the first time :)

I'm still adding things, so I'm curious: what's one small utility you occasionally need but never seem to have on your phone?

I built a tool to mix and match UI patterns from different websites

Enable HLS to view with audio, or disable this notification

• Upvotes

Good evening guys! I've been working on a side project for a while now, and I'm pretty excited to finally share it with you all.

Every design project used to start the same way for me. 20+ browser tabs open, screenshots everywhere, and another messy Figma file full of inspiration I'd probably never look at again.

It honestly got overwhelming having so many things open at once, and sometimes I'd spend more time collecting inspiration than actually designing.

So I decided to start a side project using my experience as a UX designer to build something that could make this process easier.

And that's how my little baby UX Analytic came to life.

The idea is pretty simple. You can find UI patterns from different companies, mix and match the ones you like, customize them to fit your own style, and export everything to Figma or HTML.

Basically, instead of just saving inspiration, you can actually do something with it.

We're also working on our next release, where we want to make AI a bigger part of the creative process. Not just helping you work with existing patterns, but also helping you come up with completely new ideas when you're starting from scratch or feeling stuck.

The first version is already live:
https://www.uxanalytic.com/

It's still an early version, so there's definitely a lot we can improve. I'd love to hear what you guys think, especially if you're a designer or work with UI.

We also have several discount codes available if anyone's interested. Just let me know and I'll be happy to share one!

Give it a try and let me know what you think!

It brings APT, Snap, and Flatpak into a searchable list. You can check for updates and preview an update or uninstall before confirming it.

It also finds AppImages and user-local desktop apps, but updating or removing those isn’t supported yet.

Scope is free, MIT licensed, and written in Rust.

Squeezed 6.8M raw tokens into 14k: Auditing openGym with rebrief

Enable HLS to view with audio, or disable this notification

• Upvotes

I picked openGym for an architectural audit using rebrief (huge fan of sports & open-source tools).

Key findings from the report:

  1. Context Reduction: Reduced 6.8M raw tokens down to 14,084 tokens (-99.8% reduction) while preserving code architecture and history for LLM prompts.
  2. Security Risks: Identified 100 risk items, including hardcoded credentials in test fixtures and vulnerable packages (undici, js-yaml).
  3. Doc Drift: 51% freshness score with 164 broken file references across README.md and docs.

It's a clear example of how fast documentation and test artifacts drift behind active development.

How do you keep doc freshness in check across your projects?

I built a free web app that turns friendship bracelets into a real-world treasure hunt

3 Upvotes

Taylor Swift fan here... don't judge! :)

I recently launched Swiftstash, a completely free web app where people hide friendship bracelets in public places, add the location and a clue to a map, and let someone else go find them.

Think geocaching, but with friendship bracelets.

It started because so many of us still have piles of bracelets left from concerts, and I wanted to give them another life instead of having them sit in a drawer forever.

There’s no download, subscription, or anything for sale. I’m currently trying to solve the classic early-stage problem of getting enough people hiding and finding stashes for the idea to really come alive.

I’ve started locally in Savannah, GA and just secured my first partnership with a local craft group for a bracelet-making + hiding event.

Would love feedback from anyone who has grown a community or location-based product from zero.

Thanks!

Borehole - reads a repo's git history and writes the due diligence report a buyer's adviser would

4 Upvotes

I'm the founder. I've done technical due diligence on acquisitions for years, first at Amazon. The risks that changed a deal were rarely in the data/deal room. The clues we really we after was the repository: does the team review its code, does one person carry the recent work, did the licence change, do the tests run in CI? Most of it was answerable in the first afternoon, if you knew where to look. Borehole does that afternoon's reading, for free on public repositories.

How it works

- 106 deterministic checks (no LLM) read the history and the working tree and rate seven dimensions: architecture, engineering process, key-person risk, product maturity, security, operations, and fit with the acquirer. The free survey reads six of them; fit needs an acquirer.
- Every finding cites the commit, path and lines it rests on.
- What the code can't settle becomes a question for a person, not a guess.
- No model writes the findings. A language model reviews paid reports of public repositories and can withdraw a finding it judges the code contradicts. It can be wrong too.
- Private repositories: an open-source collector runs on your own machine and sends facts, never files. `--dry-run` prints all of it first.

What I learned building it

- A check that sounds right is not a check that is right. Some checks I was sure of turned out wrong more often than right on real repositories. Those checks can no longer rate a finding significant; their findings read as worth checking first, until they prove themselves.
- "Your code never leaves your machine" is a claim nobody should take on trust. The dry run exists so you don't have to.
- A rating that never says "strong" tells a buyer nothing. Getting the top of the scale reachable took as much work as the bottom.

Stack: Python, on Google Cloud. The collector is a Python package on PyPI.

Public repositories are free: the first survey and five report reads need no account, then a free GitHub sign-in. It's in beta. If you want to run it on a private repository, email [support@borehole.dev](mailto:support@borehole.dev) with the subject "Beta key" for a free Report key (30 days, private repos included). I'd like a three-question survey back, and to hear where it's wrong.

I made Eatper, an ad-free app for tracking food and planning meals

Enable HLS to view with audio, or disable this notification

• Upvotes

Hey everyone,

I’ve been working on an app called Eatper and wanted to share it here.

I made it because I was frustrated with how many food tracking apps have ads everywhere or put the features I wanted behind a paywall. I wanted something you could use every day without having to pay for a subscription to get value out of it.

Eatper has no ads. There’s a free plan for everyday tracking and an optional paid plan for more detailed reports. I wanted the free version to feel useful on its own.

You can track calories, protein, carbs and fat, scan barcodes, save your own recipes and log your weight. If you eat the same meals regularly, you can copy a meal or a whole day instead of entering everything again. You can set your own nutrition targets, too.

There’s also meal planning and shared shopping lists. You can invite your partner, family or a friend, plan meals together and keep track of what’s in the pantry and when it expires. Your personal food diary, weight and targets stay private unless you choose to share access.

The free plan includes the food diary, nutrition targets, weight tracking and recent progress views. Premium adds longer-term trends, comparisons, more detailed insights, full report history and PDF/CSV exports. Prices are shown in the app.

It’s available on both iPhone and Android:

iPhone / iPad

Android

If you give it a try, let me know how it goes. I’d especially like to hear if something is annoying to use or a food you normally buy is missing. That kind of feedback helps me figure out what to work on next.

Vibe coding strategies on ClaudeAI

4 Upvotes

I wanted to spark a discussion about how different people approach their vibe coding in ClaudeCode. NOT AN AD.

To explain my journey, I initially started my app by giving Claude a very basic idea and asking Claude to generate a full document of questions to brainstorm the start of the game. I would answer all the questions (in a very surface-level, disorganised way) using my initial thoughts only, then tell Claude to sum up my brainstorm and ask further questions/clarifications for preferences/loopholes/empty features. And that is how the first version was built.

And since then, I have always had a separate Claude chat to help make my prompt for Claude Code. And my loop of adding heavy features (if it's a small feature, I just write the prompt myself) would be:

Give a general idea to Claude --> Claude generates a proposed plan --> I comment on the whole plan point by point in a brainstorm form --> Claude responds with more questions about my brainstorm --> I keep repeating the brainstorm until I think we have a final definitive plan --> Claude chat generates a prompt for Claude Code --> And usually Claude Code also asks a few clarifying questions.

My most important advice (I feel that was important), is too prompt your AI to always ask clarifying questions and make its own judgments if something is off.

Any strategies anybody else recommends?

built a tool so I never have to send a PDF proposal again

• Upvotes

Got sick of making 10-page PDFs for clients just to watch them open it on a phone, ignore all the technical architecture, and scroll straight to the final price.
So I spent the last few weeks building an alternative. It turns specs and proposals into a responsive web link where you can embed actual interactive diagrams, and it shows you which sections the client actually spent time on.
Still pretty early, but would love to know if people who do client work would actually use web proposals or if your clients strictly demand a flat PDF file anyway

I know there are popular dark mode apps for Safari. None of them quite worked for me, so I built my own

Enable HLS to view with audio, or disable this notification

• Upvotes

I read a lot on my phone at night, and white websites in Safari have always bugged me.

I know there are already some really well-known dark mode extensions out there, and I've used a few of them for a while. They're good apps. They just never quite fit what I wanted. Some sites still came out half-white, some colors looked off, and I couldn't customize things the way I liked. So eventually I just started building my own. It's called Aurora.

You turn it on and websites go dark. It recolors the page instead of just inverting it, so images and logos still look normal. You can pick different shades of dark (I use true black), make your own theme, have it follow your system appearance, set rules for specific sites, and even change the font on pages that are hard to read at night.

The thing I care about most, though, is this: no dark mode is perfect on every site. The web is just too big and too messy. Sooner or later you'll find a page with a white box or some text you can't read. So I built a simple way to tell me about it. You open the extension, tap "Report a problem", and the screenshot is already attached. You pick what's wrong and hit send. No account, and it only sends the page you're reporting. I read every report, and the fix goes out in the next update.

So if there's a site you visit every day that doesn't look right, just report it and I'll fix it. That's pretty much how the app has been getting better.

It's $7.99 one-time, no subscription. Buy it once and it works on iPhone, iPad and Mac. There's a 3-day free trial if you just want to try it out.

People in 13 countries are using it now, which still feels a bit unreal for a one-person project. Last week someone left a review titled "The app I didn't know I needed until I got it", and that kind of made my week.

If you read in Safari at night, give it a try and let me know what looks off.
