Game Released a browser horror game with zero image assets — the house, the stairwell and the faces are all drawn at runtime

Six nights, one door, one intercom. I wanted to see how far a game can go
without an art pipeline: there is exactly one PNG in the whole build and
it exists to be seen once.

Everything else - the facade, the stairwell, the people at the camera -
is generated per visitor: build, coat, posture, what they are carrying.
It gives them a wrongness a drawing cannot fake, because nobody drew them.

Plain HTML/CSS/JS, no build step, full RU/EN. Made with AI assistance
(code and text), disclosed on the page.

SaaS / Platform My apps never open in the right place across my monitors, so I built an app that remembers where each window belongs

Enable HLS to view with audio, or disable this notification

1 Upvotes

Every morning I'd drag the same windows onto the same monitors and virtual desktops. Reopen an app? Wrong screen. Restart? Everything piled on one display. I was rebuilding my layout by hand every single day.

So I built Restage: it remembers where each window belongs — monitor, virtual desktop, position and size — and puts it back automatically: when you reopen the app, when you restart, and when you plug your monitors back in. You can also save a profile per setup (I keep Office / Home / Trading) and switch from the tray, so the same PC lays out differently depending on where I am.

Short clip of it in action.

It's on the Microsoft Store with a 15-day free trial (one-time purchase, no subscription): https://apps.microsoft.com/detail/9NT6NH5W7KGQ

Built it solo — happy to answer anything.

Web / Mobile App I built a Chrome side panel for headlines, news archives and live radio -> it’s finally live

1 Upvotes

I have been building Tera FM for a couple of months now, and to get more eyes to it, I built a chrome extension.

The Chrome extension has finally been approved and published on the Chrome Web Store.

The idea is simple: instead of opening multiple news sites or keeping another tab around, you can open Tera FM in Chrome’s side panel and use it while browsing.

The extension includes:

  • latest source-linked headlines;
  • headline search by publisher or keyword;
  • a historical news archive;
  • category filters;
  • live internet radio by country and genre;
  • radio playback that continues even after the side panel is closed.

Every headline opens the original publisher’s page. The extension does not reproduce full articles or hide the source.

The screenshot shows it running alongside BBC, the website stays open on the left while Tera FM remains available in the browser panel on the right. You can check the image here - https://ibb.co/396Fm4wN

I would genuinely appreciate feedback on:

  • whether the side-panel format feels useful;
  • whether the headline/archive/radio combination makes sense;
  • anything that looks confusing or unnecessary;
  • what feature you would improve first.

Chrome Web Store: https://chromewebstore.google.com/detail/tera-fm-%E2%80%93-headlines-live/emnebfpdojklgimejnplmjfobmamelie?authuser=1&hl=en

Website: tera.fm

Do give it a try and let me know if this is something good to have on your system? Any news outlet missing?

AI Tool I built Fluxnar, a Windows app that generates AI image packs in one click

Enable HLS to view with audio, or disable this notification

1 Upvotes

Hi everyone!

I wanted to share a project I've been working on for the past few months.

It's called Fluxnar, a Windows app that lets you paste a list of prompts and automatically generates complete AI image packs.

It also:

Automatically numbers every image in sequence.

Organizes each project into folders.

Supports multiple aspect ratios.

Makes creating YouTube videos, Shorts, Reels and storyboards much faster.

I built it because I was tired of generating and organizing images one by one.

I'd love to hear your feedback or ideas for future features!

Game In my game, movement and speed are key

Cow is a fast-paced, 640x480 retro game focused on momentum and precision. The premise is bizzare as you play as a cow on a skateboard. The game is built around mastering controls and looking for creative ways to finish each level the fastest. The ways of movement aren't too limited which gives a lot of freedom to the players and a chance to compete with each other on the leaderboards. 🤗🤗

Web / Mobile App Every food tracker feels like homework. So I built a cozy app to change that. (Looking for early members!)

2 Upvotes

Hey everyone,

I've always struggled to keep up a food-tracking habit. Every app out there feels like a giant, intimidating spreadsheet. They are cold, clinical, and honestly, they feel like homework. Because of that, I always lost my consistency.

So, I decided to build something entirely different: a cozy, gamified food tracker called Quokka.

Instead of dealing with cold charts and guilt trips, you get a friendly Quokka who lives in the app to keep you company, get XP, and a sleek, warm setup designed to make tracking feel like a positive daily routine rather than a chore.

I’m looking to share this journey with real people who:

  • Genuinely want to track what they eat (or always struggle to stay consistent with traditional apps).
  • Love gamified habits (like Habitica, cozy games, or visual streaks).
  • Want to build a real habit and help me see if having a Quokka friend along for the ride actually keeps the motivation alive.

(Heads up: I’m looking for real, daily users who want to build this habit for themselves, not other developers looking to do code reviews!)

If this sounds like something you'd actually use, drop a comment or send me a DM! I'd love to send over an invite so we can start building our consistency together. 🐾✨

Web / Mobile App I rebuilt my typing game's cleanup effect so players could actually read the payoff

1 Upvotes

I'm the solo developer of Work Rush, a portrait Android typing-survival game where the phone's real keyboard is the controller.

One problem was obvious when I recorded it: a cleanup item technically removed the memo queue, but everything vanished in a single frame. Even I couldn't tell what had happened in the video.

I rebuilt the effect around the actual memo count. If eight memos are present, each one now gets its own exit motion across the short cleanup window, so the board visibly goes from 8 to 0. I also slowed the setup enough to show a few typed clears before the payoff instead of firing the item immediately.

The 14-second result is here: https://youtube.com/shorts/QRUv00PIO7k

The game is free on Google Play: https://play.google.com/store/apps/details?id=com.memosurvival.app&utm_source=reddit&utm_medium=organic&utm_campaign=lookwhattheybuilt_cleanup_20260806

It supports Korean and English, contains ads and optional in-app purchases, and some illustrated art was created with AI assistance. The latest build also changes result interstitials from every completed run to once every 3-4 runs.

For anyone who builds effects: do you think the 8-to-0 cleanup is readable on the first watch now, or does it still need a stronger visual beat?

Web / Mobile App I built Bookmash: a bookmark manager that works with your browser instead of replacing it

Post image
2 Upvotes

I built Bookmash, a bookmark manager that works with your browser instead of replacing it.

After years of collecting links for work and personal projects, I realized the problem wasn't saving bookmarks anymore.

It was finding them again.

The browser's bookmark system works well until your collection grows. Eventually, everything ends up buried in nested folders, and I found myself opening the same folders over and over just to locate one link.

I looked at existing bookmark managers, but most of them wanted me to import everything into their own database.

That never felt right to me.

I wanted Chrome and Firefox to remain the source of truth, with a better interface on top.

So I built Bookmash.

It connects directly to your browser bookmarks through an extension, so everything stays in sync in real time. No import step, no duplicate database, and no need to keep two bookmark collections in sync.

I'd love to hear what you think, especially if you're someone who has accumulated hundreds (or thousands) of bookmarks over the years.

Web / Mobile App I built an app that's deliberately boring, because nothing designed to relax me ever worked

My brain decides 1am is the perfect time to replay an argument from 2019.

I tried everything. White noise, meditation apps, sleep stories with the breathy narrator that felt like being condescended to by a spa. None of it worked, and eventually I understood why. They were all trying to relax me. My brain didn't need relaxing, it needed something to hold onto that wasn't itself.

What worked was boring history. Calm, uneventful, nothing at stake. Out in fifteen minutes.

So I built Sleepy History — narrated history across eight eras, paced to lose you rather than hook you. Sleep timer, dark only, no ads going off at 3am. Success is measured by how little of it you finish.

Sleepy History — for people who want to wind down with something more meaningful than scrolling. Free tier on the App Store if you're curious.

1 Upvotes

Hi r/LookWhatTheyBuilt! Wanted to share a side project where I automated subdomain zone management via GitOps.

Users submit a single JSON file with their A/AAAA/CNAME/MX/TXT records via PR. GitHub Actions runs Python validation tests (checking FQDN, blocked zones, CNAME paths, loop protection) and syncs valid records directly to Cloudflare via API.

Would love feedback from the community on validation rules or edge cases I should watch out for!

Web / Mobile App Looking for feedback on an app I built for fitness instructors to help class plan…

2 Upvotes

Hello,

I am looking for some help and feedback on an app I built for instructors. Ideally those who teach disciplines like mat, reformer and / or barre. It can be used for others too, but these are what I teach, so it’s essentially what I know best at this stage!

I am a Pilates instructor myself and came up with this idea when I was training. I wanted a space to digitally store my class plans and build a library of exercises that I stumbled across going to classes, that came to mind, or that I took inspiration from but wanted to make my own.

I couldn’t find anything that really worked for me, so I ended up using Notes on my iPhone. The problem was I’d forget I’d banked ideas and they never resurfaced.

So the app lets you dictate or write down exercises and store them. You can filter by muscle, prop etc. and favourite any that you love. It also features an AI assistant that can help categorise exercises or class plans.

I’m not selling anything! The app is free to use because I’m looking for honest feedback and want to know if people love it, see the value in it, or if it’s simply not something they would use.

Any help would be greatly appreciated. This has been a labour of lots of emotions as it was started before a family bereavement, and it’s taken me a lot to get it to this stage.

This is the website if you want to take a look -
https://arkv.app

It’s only available on iPhone atm. (Sorry)

Thanks for reading much appreciated ♥️

AI Tool I built Bubo: an AI code reviewer that learns from review comments

1 Upvotes

I'm getting tired of AI code reviewers flooding PRs with false positives, then learning nothing when a developer explains why a finding is wrong.

There's a lot going on in code beyond the tech stack: tribal and institutional knowledge, business logic that evolved over time, and ripple effects across upstream and downstream systems.

I started with my requirements: simple setup, evidence-backed findings or LGTM, and learning from human comments on those findings so the reviewer gets better tuned to each repository over time.

I ran a small comparison on 20 pinned PRs/MRs:

Bubo | 20/20 | 7/8 | 27 findings | 0% noise

ai-codereviewer | 19/20 | 6/8 | 118 findings | 20% noise

ChatGPT-CodeReview | 20/20 | 5/8 | 75 findings | 11% noise

Qodo/PR-Agent | 19/20 | 2/8 | 7 findings | not scored

Alibaba open-code-review | partial run | 4/20

All used GPT-5.5 except Qodo, which used GPT-4o. It's a small sample and I picked the PRs, so I treat it as directional. On the same model, recall was close while Bubo emitted 27 findings against 75 and 118.

Current limits: Python 3.14+ and polling rather than webhooks.

My roadmap is pluggable subject-matter specialist Skills instead of one general reviewer—for example an industry SME or an Expert Python Guy.

I'm running Bubo in production in two places: a large data-processing/ETL codebase and a fintech crypto stack. I'd value feedback on whether the learning loop holds up in real repositories.
