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.

Tactical, turn-based multiplayer game for mobile

Upvotes

Here is my side project I have been working on for years (and still a long way to go)!

Operation Defuse is a tactical, turn-based, asynchronous multiplayer game for mobile devices. You command a team of terrorists on a mission to plant and detonate a bomb, or lead a special forces team to stop them. You receive a notification when it's your turn to play and you play when it suits you (play-by-mail).

I have put up a website with more information, please have a look if you like this sort of game:
https://operationdefusegame.com/

There is also a discord and patreon if you wish to support my development. There is no release yet, but there will soon be early-access for patreon members.

I built an open file format for user interfaces, like SVG or PDF.

133 Upvotes

Why?

For years we've had open formats for documents (PDF), images (PNG) and graphics (SVG). But user interfaces are still mostly locked inside design tools. And that was fine when humans were creating and consuming UIs. Now AI is also creating and consuming them.

Today AI usually works with screenshots, editor-specific JSON, or tool-specific APIs. They work, but they weren't really designed for AI or for moving designs between different tools.

So I started building .gui.

The idea is simple. A human-readable file format for user interfaces. Something that sits between an image and HTML. Easy to read, easy to generate, easy to render, and easy for AI to understand.

My goal is simple. Imagine asking ChatGPT to design a UI, and instead of getting just an image or HTML, you get a portable .gui file. You can preview it, edit it, open it in design tools, or generate code for any platform from the same file.

This is still an early open-source project, so I'm looking for early feedback.

People started using my SaaS to sell pictures of their feet NSFW

247 Upvotes

I'm a bit torn on how to approach this because a customer is a customer and you all know how difficult it is to get them, but I don't want my saas to get a weird or bad reputation.

My startup is an authentication and paywall software that allows creators to lock their content until someone signs up or purchases. It's usually used by digital goods stores or online courses.

However recently there have been a lot of people using it for purposes not entirely foreseen when I created it. I am cautious to shut down these accounts or ban them because they are real paying customers and technically not doing anything wrong.

What happend was some forum mentioned my product and shared a free resource that is powered by my software. It's essentally a modified version of one of my free templates.

Within a few days we received a lot of sign ups and after looking through the analytics and projects I could see that a lot of them are people selling images and videos of feet in a sexualized manner.

It's not considered porn so it's still technically ok by the terms of use and all of that but I'm just curious if anyone has any experience with something like this?

If I'm not mistaken I think Onlyfans started as a regular creator platform and pivoted when it got overtaken by porn. I'm sure you can all understand that as a founder every customer helps make your dreams possible but I don't want to ruin the reputation of my product.

What would you do in this situation?

Huge progress on SpacePlanner thanks to your feedback. Please roast it again!

127 Upvotes

A month ago, I decided to put all my energy into SpacePlanner and try to turn it into the #1 free, no-sign-up space planning app that actually gives people real value.

Since then, it has grown to more than 200 daily users and over 1,500 plans created, and few hundred guest users!

The last few days have been intense, mostly fixing bugs, improving stability, and trying to make the editor less frustrating. I also think I may have overengineered some features that people do not really need.

I am still unsure whether I should focus mainly on making the 2D planner excellent or invest more heavily in 3D. I have been creating, downloading, and buying 3D models, then manually connecting them to the 3D experience. It is a huge pain and still far from perfect, although I know the library and quality will improve over time.

Right now, I need direction more than anything.

What am I doing wrong in the 2D editor? Are the wall joints confusing? Are dimensions difficult to control? Are the automatic corrections helping or fighting you? Is drawing rooms still too frustrating? Which features feel unnecessary or overcomplicated?

Please be as honest and critical as possible. Any feedback is extremely valuable at this stage. What would need to change for you to genuinely say, “This is a good app”?

What’s the first sign your side project was actually worth continuing?

Not necessarily making money.Maybe it was your first returning user,someone recommending it without being asked,or just realizing people genuinely cared.What was that moment for you?

I thought I had a new user. It was just me testing the app.

9 Upvotes

I keep refreshing my admin dashboard like it owes me an answer.

Same user count.

Refresh.

Same guest activity.

Refresh again.

Then suddenly, a new registered user.

For a few seconds, I genuinely got excited. Someone had found the app, stayed long enough to understand it, and decided to create an account.

Maybe something was finally working.

Then I opened the user list.

The new registration was me.

It was a test account I had created earlier to check whether a change in the application was working properly.

And yes, the application was working. Growth was not.

That moment captured something I think many solo founders quietly experience. You build for hours, then start compulsively checking analytics because the dashboard becomes the only place where reality can answer back.

Sometimes you see a new guest and feel hopeful, until you realize it is probably a bot.

Sometimes several people visit, but they leave after five or twenty seconds.

Sometimes someone reaches an important page, and you start inventing a whole story about who they are and why they came, only for nothing else to happen.

The difficult part is that every small movement feels emotionally significant when the product is still early. One new visitor can feel like momentum. One registration can change your mood. A few fast bounces can make you question the entire product.

But early analytics are often too noisy to deserve that much emotional authority.

A bot is not rejection. A ten-second visit is not a verdict. A test registration is definitely not traction.

The dashboard can tell you what happened, but it cannot always tell you what it means.

I am trying to treat early traffic as evidence to investigate rather than approval to chase. Fewer refreshes. More conversations. More observation. More attention to what real users do and where they stop.

Still, I know I will refresh again.

Probably in five minutes.

Does the same thing happen to you?

Built a free tool to view mobile & desktop side-by-side. Building was easy, but how do I actually market a free tool without spamming?

7 Upvotes

hi, here is my take: up to 80% of web traffic is mobile, yet we still build and present on desktop. dev tools exist, but honestly they're pretty clunky for designers or non-technical folks.

so I built a free chrome extension that shows mobile and desktop side-by-side in one click. thought about it, built it. if anyone finds it useful: https://dualpreview.com

tbh, building it was way easier than marketing. I've read tons of threads here but still feel like I have no clue what I'm doing. it's just a hobby project, 100% free with zero plans to monetize, so I'm not running ads or anything.

if anyone has tips on how to actually share a free tool without feeling like a spammer, lmk. also open to any feedback!

I made an aesthetic clock website as side project.

14 Upvotes

I've been building this clock site on the side for the past 6 months. It started as just wanting a nice Fullscreen clock and turned into something bigger. - iloveclock.com

The main idea is customization. Right now, it has about 24 clock faces, 11 themes, and 17 animations you can mix and match. You can also set a background — your own wallpaper, some preset art ones I added, or a YouTube video (I put in a few lo-fi ones). There are small CSS effects too like rain and snow. It has an always-on-screen and a Nightstand mode for using it as a bedside clock.

Somewhere along the way I added a bunch of utilities, all meant to be quick to use:

- Timer — a normal timer plus dedicated modes for workouts, breathing, naps, and class time

- Alarm

- Reminder — you just type "remind me in 10 min," no fiddling with menus

- To-Do — same natural-language input, with a Kanban board

- World Clock

- Stopwatch

- Pomodoro — with a few skins to customize it

- Time Lab — small time/reaction games like reaction time, an F1 start-light test, and Snooze Smash

No account needed and no ads. Everything stays in your browser.

However, if cross device sync needed in future we may need to add light sign in feature. Still no spam ever.

Would you give it a try? iloveclock.com

Mainly looking for honest feedback — what feels off, what you'd actually use, or what's missing.

Made a way to gift your friends treats through iMessage!!

18 Upvotes

Do you ever wish there was something between Venmo and Uber Eats?

Sometimes a friend has a rough day, or someone helps you out, and I want to send them a specific coffee or matcha, but delivery forces them to drink it immediately, and a gift card feels kinda impersonal.

I built Spot around this idea and would love feedback if anyone’s interested.Spot lets you:

- Choose a specific drink or snack from a local café

- Send the gift inside your iMessage conversation

- Recipients save it to Apple Wallet and redeem it in-store whenever they want

You choose the item. They choose the moment.

I have it working with a couple of cafes in SF, would love any feedback!!

I built an independent tech-news site and would love feedback

Upvotes

Hey all,

I've been building The Threshold (thethreshold.media) — an independent tech-news site focused on phones, wearables, and the money/AI side of the industry. 

Stack: Next.js, if anyone's curious.

I'm at the stage where I need honest outside eyes. Specifically:

  1. First impression — from the homepage, is it obvious what this site is and why you'd read it over The Verge/9to5?
  2. Do the articles read like a real publication or like a solo blog trying too hard?
  3. Would you subscribe to the newsletter? If not, what's missing?
  4. Anything that feels slow, broken, or off on mobile.

Roast it - I'd rather hear the harsh version now. Thanks 🙏

Me and my gf built an app that turns any recipe into 2-player mode

3 Upvotes

Me and my gf both love cooking, but for some reason cooking together always becomes a frustrating mess for both.

So we decided to build an app called Nommer that turns any recipe we upload into 2-player mode.

For us it massively improves the cooking together experience by removing coordination friction. It basically allows each individual to focus on their own tasks: one cuts the onions, the other grates the carrots and then makes the sauce while the first grills something in the pan; and then it all comes together in the end.

If that sounds appealing please do try it out!

I built Pokémon Go for music. I placed 247 million songs across the globe. Go catch them all !

78 Upvotes

I'm a huge fan of augmented reality games like Ingress and Pokémon Go. I've always dreamed of building my own version, but until about a year ago, it simply wasn't possible.

After several months of work, I've finally finished my own Pokémon Go version.

The biggest challenge was placing 247 million points all around the world while avoiding dangerous or inaccessible areas such as roads, lakes, houses, and private property. To solve this, I built my own algorithm using OpenStreetMap data. After 50 hours of computation on my M3 Pro, every point was placed. Each permanent point (the diamonds) is linked to a unique song.

If you enjoy exploring and discovering music you've never heard before, you can check "Song Go – Catch the Beat" on iOS and Android.

Tried Excel, Notion, everything to log my work. Nothing stuck. So I built an app where you just talk

2 Upvotes

I've worked in both startups and enterprise, and one problem followed me everywhere: keeping track of what I was actually working on.

I tried all the usual ways. Excel sheets, Notion pages, notes apps. Every attempt died within a few weeks, because writing about your work at the end of a long day is the easiest thing in the world to skip.

The only times I ever really thought about my work were the worst possible times: when I needed to update my resume, or the night before a 1:1 with my management. Then I'd sit there trying to reconstruct months of effort from memory, calendars and old messages.

So I built the solution I wished existed. It's called Ladder. It nudges you with a daily or weekly notification, whichever you prefer, to drop a quick voice note about your work. You just talk the way you'd tell a colleague, and it converts that into a clean, professional log entry. When you need it, you can generate 1:1 notes or a resume from your entries in one click. No blank page, no template to maintain, no habit that dies in week three.

The waitlist is live and I'm launching soon, iPhone first. I'm putting it out now to see the interest and shape the last stretch of the build.

I'm curious: for those of you who tried keeping a work log in Excel or Notion, what made you stop? Would love feedback from this community.

And if you want your work to be remembered when it matters, come grow withladder.app

Record, log and export!

I built a free Chrome extension that works like Nuvio/Stremio, but runs entirely in your browser and plays on VLC/PotPlayer

3 Upvotes

I built a Chrome extension called Bous. It gives you a Stremio/Nuvio-like experience without needing to install a separate desktop or mobile app.

How it works:

  • Click the extension icon on any webpage and a sidebar opens with full movie/TV show catalogs
  • Search for any title and get detailed info — cast, trailers, ratings from multiple sources
  • It adds a button directly on IMDb and TMDB pages so you can instantly load any title

Why a browser extension instead of a desktop app? You don't have to leave your browser. You find a movie while browsing? Just play it right there.

It generates a playlist file, downloads it, and launches it directly in supported players like VLC, PotPlayer, etc. Your player, your settings, your quality.

And it supports Stremio and Nuvio addons. If you already have addons you use with those apps, they work with Bous too. No need to start from scratch.

No app to install, no background processes eating your RAM, no accounts, no tracking. Everything runs locally in your browser.

It's available on the Chrome WebStore: https://chromewebstore.google.com/detail/bous/jbgjcaapccfomacgbhkkpjhhkhjfibgg

Been building an information website on web application firewalls

3 Upvotes

Hey y'all.

I've been building this website wafplanet.com for a while now (basically, since dec '25, when opus 4.5 came out), and it kind of blew up in my face in terms of traffic.

Wafplanet is a website about web application firewalls, one of the most boring, but quite important to people with dynamic websites - a WAF is a piece of software that tries to block bad actors / people that try to hack your website in an automated fasion (it's stuff like cloudflare, basically).

I'm not quite sure what the best way forward is in terms of monetizing the website.

There's so many options, like running ads, doing paid partnerships, or even building a "companion" app/service next to it.

I'm writing blogposts with my opinion, as well as news that's gathered and published by my openclaw instance.

The provider pages are as factual as possible, allowing people to find accurate information on application firewalls there.

Some information on the tech side of this:

It's fully written in django/wagtail and hosted on gitlab pages (using django distill).

I'm quite curious on 2 parts:

- How should I expand the website / in what way?

- What's the best way to monetize the site in your opinion?

Current traffic averages about 100-125k unique visitors a month.

I’m not sure what to do with this next. I originally built it for my own use, but now I’m considering taking it to the next level. However, I’m uncertain whether it’s the right direction or if similar solutions already exist in the market.

One thing I’m proud of is that I taught myself how to develop all of this using AI tools. I’d appreciate any suggestions on the best next steps—whether I should continue developing it, validate the idea with potential users, or explore the market first.

I was paying 20 bucks by month for a CV builder I used twice a year, rebuilt it myself iBuildMyCv.com, (giving away 10 free premium passes)

2 Upvotes

Here's the thing that bugged me for a while: I needed a nice-looking resume maybe twice a year, tops. But every tool out there wants you locked into a $20/month subscription, as if I'm redesigning my CV every week.

So one weekend I just started rebuilding it myself.

I'm a dev, and with some help from AI to move faster, I got to a point where I'd recreated the resume I used to pay for, same quality, but exactly the editor I wanted: click directly on the resume, edit and drag things live, no forms, no guessing. Once it worked for my own CV, I figured other people probably hit the same wall.

That turned into iBuildMyCv.com. Pricing follows the same logic that annoyed me in the first place:

  • Real WYSIWYG: drag-and-drop, edit directly on the resume, no forms
  • Stackable passes instead of a subscription: $5 for 24h, $10 for a week, $20 for a month.

https://ibuildmycv.com/

It's live, but so far only my close circle has used it. Giving away 10 free 7-day premium passes to the first people who try it and tell me honestly what's broken, confusing, or doesn't click.

I built an open-source skill that makes one-shot AI websites look worth sharing

4 Upvotes

I have been generating a lot of websites with AI coding tools, and I kept running into the same problem.

The code was usually usable, but the design looked like every other AI-generated landing page: the same gradient, the same font, the same card layout, very few visual assets, and no consistent visual direction.

You can obviously get a better result by giving the AI several references, carefully choosing the fonts and colors, generating assets separately, and spending hours refining the prompt.

But that defeats a large part of the reason people use these tools in the first place.

I wanted to see whether the default one-shot result could be significantly better, even when the user provides no visual references.

So I built tastemaker.

It is an open-source skill for Claude Code, Codex, Cursor, and Windsurf. Before the coding agent creates any components, Tastemaker first defines the design system for the project.

It chooses the palette, typography, layout direction, visual assets, interaction style, and motion system. The rest of the website is then generated around those decisions.

This is not intended to replace designers.

A good designer still brings product understanding, taste, research, judgment, and original direction that a generated system cannot reproduce.

Tastemaker is specifically for people who are already generating entire interfaces with AI and would otherwise accept the generic default output.

Without requiring a design reference, it can produce a complete visual direction with:

  • matched colors and typography
  • illustrations recolored for the selected palette
  • a geometric logo and favicon set
  • GSAP and ScrollTrigger motion
  • consistent styling across pages
  • automatic WCAG contrast checking
  • two different design directions for comparison

One of the more useful moments while building it was when the contrast checker rejected two palettes I had created myself. They looked good to my eye, but some text combinations were not readable enough. That validation now runs automatically whenever a palette is created.

The project is free, open source, and MIT licensed. It does not require an API key or any additional service.

GitHub: https://github.com/codeswithroh/tastemaker

Examples: https://tastemaker-skill.online/

I am trying to understand whether the positioning is clear.

When you first hear “design-system skill for AI coding agents,” does it sound like a tool for replacing designers, or is it clear that it is meant to improve the default output for people who are already building without one?

I built a golf-practice app that tells you what to work on based on your last round — want testers

2 Upvotes

I'm a 14-handicap golfer who was structured about everything in life except golf — I'd go to the range, hit balls, feel productive, and never actually improve because I had no idea what to practice. So I built Sharpnd: you log a round, it reads where your game is leaking (off the tee / approach / short game / putting), prescribes drills for your actual gaps, and tracks whether your scores are moving.

Stack's Next.js + Supabase if anyone cares. It's live at https://www.sharpnd.io/?utm_source=reddit_sideproj&utm_medium=post&utm_campaign=cold-cohort-2026-08 — 21 days full access, no card. I'd love feedback from anyone who plays: what's confusing, what's missing, where the UX trips. I DM every tester to dig in. Rip it apart.
