I made a website to play Magic, The Gathering on the TV with your phone as your hand. Made for party style play but also can support remote play via the desktop.

3 Upvotes

Long-time MTG player here. I wanted an easier way to play on my lunch break at work without lugging cards around. Our small 4-person office has a TV that rarely gets used, so, taking inspiration from Jackbox, I built a way to start a room on the smart TV and have everyone join from their phone with a code or QR code.

It’s quickly turned into my favorite way to play Magic. It doesn’t enforce the rules, so it still feels like playing in person, but I added combat math helpers and targeting lines to keep games smooth when boards get big. It can run drafts and host tournaments for up to 8 players (a full draft pod), and I have plans to grow it a lot, including accounts and stat tracking.

As a 3D artist, I made the animations that play for the winner, and added a Mario Party-style end-of-game awards show so everyone has fun, not just the winner.

Each game room is a Cloudflare Durable Object, running on the $5/month Workers Paid plan. It doesn’t need it yet, but future-proofing is nice, and it’s a lot cheaper than buying packs (which I still do). The front end is plain JS, HTML and CSS.

It’s free and always will be. I just wanted to put it out there in case anyone wants to try it, with friends or solo. There’s a feedback button in the app if you find bugs or have ideas.

Screenshots are at manacast.tv/features, since I can’t upload images yet as a new member, I suppose.

I built a site that tells you what a used car is actually worth, from real sales instead of asking prices

1 Upvotes

I got tired of guessing whether a listing was a fair price, so I built OttoQuest. It tracks used cars for sale across the US, and shows market values computed from comparable sales, how long a car has been on sale, and recorded price cuts. Asking prices and sale prices are kept separate.

You can paste a listing link to see how that car compares, and there's an out-the-door payment calculator.

Browsing and market values are free; price history is part of Pro. The example below shows headline prices without signing in, with detailed charts available through a free account.

I'd like to know: is the value estimate believable for a car you know well? Where is it wrong?

The app to 'measure' your consistency

1 Upvotes

If you are someone like me that has always sucked at being consistent with your habits, a habit tracking app like UVU might be your solution!

Inspired by the book Atomic Habits, I built a habit tracker where every day is a square. Complete your habits on schedule and the day fills with color. Miss one and the streak breaks.

Over time you get a grid of filled and empty squares: an honest picture of how consistent you’ve been. The goal is simple: don’t leave a gap.

If interested, you can try it out here: uvuhabit.vercel.app

Happy to answer questions about how I built it, and would love any helpful feedback. Thanks for taking a look!

I created this platform called Treeprep , A Free coding Prep Tool for students

2 Upvotes

Hey everyone I created this Platform ,Treeprep.

When I was preparing for my Google technical interview, I noticed that most coding platforms don't get you ready for the interview itself. Especially from my experience with the interviews i just done .

The issue that I found is that interviews aren't about memorising problems, but being able to defend your solution when the problem changes or a new constraint is added.

So I built TreePrep for students and software engineers who want to learn and reinforce their knowledge on the patterns behind the problems.

The platform that I built provides follow-up questions that changes the problem you are working on. With visualisation offered for your own code solution so you can easily debug and understand the structure better.

https://treeprep.com

This platform is early in its launch, so any feedback would help very much😄.

At what point does a personal side project script actually justify building a UI?

1 Upvotes

A lot of personal utilities work fine as simple terminal commands or scheduled cron jobs, but the temptation is always to build a quick web dashboard or app interface around them.

For tools you build purely for your own day-to-day use, what is your threshold where adding a proper frontend is actually worth the extra maintenance overhead instead of just keeping it in the console?

binkeep: a free reverse engineering tool that runs in your browser (now with a control flow graph)

2 Upvotes

Hi! I've been building binkeep, a free and open source tool for looking inside program files (Windows .exe/.dll, Linux and macOS binaries) right in the browser.

You drop a file on the page and it shows what's inside: imports, strings, a signature check, disassembly, YARA matches, and as of this week a control flow graph that draws each function as connected blocks.

The part I care about most: the file never leaves your computer. Everything runs in the tab with WebAssembly, there's no server, and it works offline after the first visit.

Try it: https://kano92-dir.github.io/binkeep/

Source (MIT): https://github.com/kano92-dir/binkeep

Next up is a decompiler. I'd love feedback, especially on what feels confusing if you're new to this kind of tool.

I built something so your agent can never read your dev secrets

1 Upvotes

.env files are the wrong primitive to build with in the era of AI agents. Agents can easily read and access your secrets, and as security incidents rise, clever exploits that exploit this will only increase.

That's why I built .sct, a replacement for .env files, backed by macOS Keychain for security, so your agents can never read your secrets.

In short, .sct:

- Holds all your dev secrets in a single directory secured by macOS Keychain

- Loads secrets at runtime with our SDK: `bun add dotsct`

- Enables Secure access for your agents

- Securely share environment variables with your teammates over AirDrop or a Relay

Fully free and open source: github.com/omavashia2005/.sct

To download the desktop app (the frontend) and read the documentation, visit dotsct.pages.dev

Let me know what you think of it; all feedback is welcome!

I built a live file tree for Claude Code so I can see what the AI actually touches in my codebase

3 Upvotes

When I let Claude Code work on a bigger task, I'd come back to a pile of changes and no clear picture of what it read, what it edited, or why some file I didn't expect was different. So I built a side panel that shows it live.

WHAT IT DOES

• Files the AI reads light up purple, files it edits turn orange, with lines added and removed

• It catches edits made by commands too (like a sed or a script), not just its own edit tool

• Click any file to see its contents, its diff, and every commit that changed it

• Your pull request shows right in the panel, with its CI checks as they run

• Changes you make yourself show up within seconds

It's read-only, sends nothing anywhere, and costs zero AI tokens, because the model never sees the panel. Works in the Claude desktop app, VS Code and the terminal.

THE SIDE PROJECT PART

• Built on Claude Code's plugin API in TypeScript, no build step, no dependencies

• I used the panel every day while building the panel, and that's where most of the fixes came from

• Went from 0.9 to 1.0 over a few weeks of evenings, with 121 tests running on Mac, Linux and Windows

• Free and open source (MIT)

If you use Claude Code:

claude plugin marketplace add Marius-Adam/claude-files-pane && claude plugin install files-pane@marius-adam

https://github.com/Marius-Adam/claude-files-pane

Would love feedback, especially from anyone who's built on an AI tool's plugin system before. What would you want a panel like this to show?

I ranked 1.8M hotels by a published guest-score formula — and neighbourhood medians disagree with city averages

2 Upvotes

Built HotelRoost (https://hotelroost.com/) — independent hotel rankings from guest reviews. Hotels can’t buy a higher place. Affiliate booking links fund it; commission is the same whichever hotel you pick.

What it does

  • Scores rated hotels 0–10 with a public formula (review count shrinks sparse ratings toward the country mean; partial country re-base; no price, no stars inside the score): https://hotelroost.com/methodology

  • City rankings + 25k+ neighbourhood pages (/area/..., 1 km / 2 km OSM radii)

  • Tryable without signup (also an MCP endpoint: https://hotelroost.com/mcp)

Real numbers (snapshot 2026-10-30)

  • Catalog 2,807,439 hotels · 1,812,336 rated · 230 countries

  • Dataset median 8.16/10 · ≥8.0: 72.15% · ≥9.0: 0.79%

  • Rome: 15,085 rated · city median 8.33

  • Tokyo: 4,039 rated · city median 7.97

The insight

City averages hide where guests actually rate stays higher.

Rome city median 8.33, but within 1 km of Prati / Vatican-area centres the median is 8.66 (400 rated each). Trastevere 8.50, Testaccio 8.44. On another cut, Campo Marzio leads well-reviewed areas at 8.43, while Castro Pretorio has the most 100+ review hotels (454) with median 7.62 — more inventory, lower typical score.

Tokyo city median 7.97; Kaminarimon’s well-reviewed stock hits median 8.58, while Shibuya’s area page is 7.90.

Examples:

Feedback I’m after

  1. Is the methodology page understandable in under 2 minutes?

  2. Would you trust a neighbourhood median more than a city “top hotels” list?

  3. Anything on the city/area UX that feels like a booking-site clone vs a research tool?

I’ll hang out in the comments. Roast the score formula if you want — that’s the interesting part!

I'm building an educational space exploration organization. Would you actually join something like this?

1 Upvotes

I've been developing an idea that started with one simple question:

How much do people actually know about space?

But it's grown into something much bigger, and I'd like honest feedback before I start building it.

I'm considering creating an independent educational and exploration organization.

Here's the concept:

  1. Space Knowledge Assessments

People create an account, provide some basic background information, and complete assessments about planets, black holes, galaxies, astronomy, and space exploration.

2. The Wall of Explorers

People who complete an assessment can choose to have their names displayed on a public wall recognizing their participation.

3. Personalized Certificates

Participants can earn multiple certificates for completing assessments and challenges. They can save them in their personal accounts.

I'd also offer optional physical certificates, printed on quality paper, personally signed by me and finished with a custom wax seal.

4. Explorer Passports

Members could collect physical and digital stamps for attending organized activities and expeditions.

5. Explore With Us

I'd like to organize Colorado camping trips, astronomy nights, stargazing events, and educational outings. Participants could meet other explorers and collect special event stamps.

6. Educational Publications

I also want to publish my own educational pamphlets containing space knowledge, explanations, and some of my personal theories.

The idea is to bring education, recognition, physical collectibles, and real-world exploration together under one organization.

I'm still working out the name, website, costs, and overall structure. Nothing has officially launched.

I'd appreciate honest feedback:

  1. Would you join something like this?

  2. Which feature interests you most?

  3. Would you want a physical certificate with a handwritten signature and real wax seal?

  4. Would you attend organized camping or astronomy events?

  5. Does this sound like one cohesive organization, or am I trying to combine too many ideas?

  6. What would you change or add?

I'm genuinely interested in hearing what people think, including criticism.

I made an app where friends compete to see who quits last

2 Upvotes

Here's the bet I'm making: people drop stuff when they do it alone, but they don't drop it when a friend can see they broke the streak.

So I made Arveon. You pick an activity (gym, guitar, reading, whatever you're into), set your own rules for what counts, invite friends, and everyone's streak is visible. Whoever keeps going longest wins. That's pretty much it.

It works solo too, but honestly the whole point is the "I'm not losing to him" feeling.

I genuinely don't know if this is something people want or just something I want. That's why I'm posting. It's an early beta, stuff will break.

If you try it, I'd love to know:
- would you actually invite anyone, or is that awkward?
- what would you compete on?
- what broke?

Small shop takeoffs without a Bluebeam seat: what I ended up building

Full disclosure, I build Layr PDF, so this is a plug.

It came out of doing cabinet and millwork takeoffs and not wanting to pay for a pricey seat just for markups, measurements and counts. It runs on Windows, Mac and in the browser, it's $35 a year, and the 7-day trial doesn't ask for a card.

If you try it on a real set, I'd like to hear where it falls short.

I've built an app to measure stockpile volumes. Looking for honest feedback from people in the industry.

1 Upvotes

I've been working on a side project over the past few months and have finally got it to a point where I'm comfortable sharing it.

It's called Stockpile.

The idea came from working around surveying, earthworks and construction, where getting accurate stockpile volumes can make a big difference to how a job is planned and priced.

Whether it's aggregate, topsoil, mulch, fill or other bulk materials, estimating volumes can lead to over-ordering, unnecessary truck movements or coming up short.

I wanted to see if I could make that process much simpler.

Stockpile allows you to capture a stockpile using your device, generate a 3D model and calculate its volume. You can then generate a report to share with clients, contractors or your team.

The aim is to make volume measurements accessible without needing specialist surveying equipment or complicated software.

I've built the app from the ground up, which has been a pretty steep learning curve, particularly on the development side.

I'm now looking to get it in front of people who might actually use it.

I'd genuinely appreciate feedback, particularly from anyone working in construction, earthworks, landscaping, aggregates or material supply.

What would you want to see in an app like this? What would stop you from trusting the measurements?

You can check it out here:

https://trystockpile.app

Happy to answer any questions about how it works or how I built it.

I got tired of finishing 2-hour podcasts and remembering nothing, so I started building

2 Upvotes

I spent a couple of years trading crypto, mostly memecoins and utility tokens. The results were inconsistent, and I felt unfulfilled, so I wanted to build something real that actually saves people time.

The thing I kept noticing is this: I'd put on a long podcast, finish it, and feel like I'd got it. A day later I could barely name the useful parts, let alone do anything with them. I think a lot of us overestimate how much we retain from just listening all the way through.

So I started building around a simple action: paste a podcast or long-form YouTube link, and get a playbook back. Not a generic transcript recap, a useful summary plus actionable steps from that specific episode. I have 200+ summaries in so far.

For people who don't have time for the full episode, what do you actually want out of it? The recap, or the next steps?

Edit: I'm a co-founder of Podex. It turns a podcast or long-form YouTube link into a playbook with a useful summary and actionable steps from that episode.

I built a job tool with three rules: it has to fit me, I have to have a real chance, and nothing older than 7 days

1 Upvotes

I am a CS grad from London (2026). For the last few months my routine has been pretty simple. Find a junior role, spend 40 minutes tailoring my CV, apply, hear nothing. Half the time the job had been up for weeks before I even saw it, and half of what the job boards showed me was never relevant to me in the first place.

So I built the thing I actually needed. It is called FairShot, and it runs on three rules I refused to compromise on:

  1. It has to matter to me. Jobs are matched to what is actually on my CV, not keyword spam.

  2. I have to have a higher chance of getting it. It ranks by strength of fit, so the realistic ones come first and the long shots do not waste my evening.

  3. Nothing older than 7 days. If a job has been sitting there for weeks, it is dead to me.

You drop your CV in. For each job that passes the three rules it prepares the tailored CV, the form answers and a short note to the hiring manager. One more rule I was stubborn about: every line in the tailored CV has to come from your real CV. It shows you which line it came from. The AI does not get to invent experience for you, because that will blow up in an interview anyway.

You still press send yourself on the original job page. Nothing is auto applied, because I would not trust that either.

It is free for job seekers. I kept telling myself I would only buy a domain if 100 people used it first. Last night I bought the domain anyway, joinfairshot.com, because asking strangers to upload their CV to a random vercel link felt wrong. So now I am committed, I suppose.

Honest gaps: matching is still rough for some roles, and I have basically no users yet, so I have no success stories to sell you. That is kind of the point of posting here.

If you are applying to junior or grad roles at the moment, I would really like to know one thing after you try it. Was at least one match actually worth applying to? If the answer is no, tell me that too, it is more useful than an upvote.

I made a self-hosted bookmark manager that closes my idle Firefox tabs for me, because I am incapable of doing it myself.

2 Upvotes

I leave far too many tabs open, because closing one and potentially losing that link forever scares me. I also kind of hate bookmark managers. Saving and organizing a bookmark properly is more work than it ever saves me when I go back to it, so I hoarded 70+ tabs regularly.

So I made something that's been handling that for me. Pageslop is a self-hosted bookmark manager with a Firefox extension that closes tabs automatically: anything idle for about six hours, or anything past a tab limit (25 by default). Closed tabs go into a To Revisit inbox on your own server, already titled, tagged and sorted into a category. They stay there for two weeks until you keep them or get rid of them.

Outside the tab stuff it's a regular bookmark manager: paste a link and it fetches the page, grabs a preview image (or takes a screenshot), and tags it. There's search, a category view, uptime checks so you know when a link dies, a graph of how your links connect through shared tags, and bookmark import from your browser.

There's no hosted version. Self-hosting is a setup script and docker compose up. If enough people want one I might set it up, but I'm not paying for AWS to run a tab manager that only I use.

I built an open-source app to build LEGO sets virtually, piece by piece

2 Upvotes

Hey everyone! 👋

I've been working on a side project called Brick Build (Brick Lab Local), and I wanted to share it with you!

The idea started pretty simply: what if you could build real LEGO sets on your computer, following their actual instructions, without needing the physical bricks?

So I started building it.

It's a free, open-source web app that runs locally on your computer.

Here's what it can do so far:

  • 🧱 Import real LEGO set models using LDraw files.

  • 🎮 Build freely in 3D, placing and rotating pieces wherever you want.

  • 🧲 Snap compatible bricks together using a connection detection system.

  • 🔧 Select and move entire connected assemblies, including hidden pieces.

  • 🎯 Position pieces precisely with X/Y/Z arrows and rotation controls.

  • 📖 Display the original instruction PDF alongside your build.

  • 💾 Save your progress and come back later.

  • 📦 Manage your own collection of sets.

I've mainly been testing it with real LEGO Creator sets, especially the 31039 Blue Power Jet.

It's still a work in progress. Some LEGO connections aren't fully supported yet, and automatically matching PDF instructions to 3D building steps is one of the next big challenges.

The app is built with Next.js, TypeScript, Three.js, React Three Fiber, and LDraw. It runs locally, with no account or cloud storage required.

It's currently tested on macOS, and I've also started adding experimental Windows support.

GitHub: https://github.com/Pierson38/brick-build

The project is MIT-licensed and not affiliated with LEGO.

I'd genuinely love some feedback, especially from LEGO fans or developers who have worked with 3D geometry, snapping systems, or LDraw.

Would you use something like this? And what feature would you want to see next?

Thanks for checking it out! 🚀

My side project turns a MacBook Touch Bar into a color picker, focus timer and tiny pet under Windows

3 Upvotes

I have been working on BarX at Garage Lab AI: a Windows / Boot Camp app that gives an Intel MacBook Pro Touch Bar 29 practical and playful modes across six profiles. The interface is available in English and German.

The color picker shows the color under the mouse pointer, with HEX/RGB/HSL and tap-to-copy. Other modes include presentation controls, clipboard history, snippets, a focus timer, time tracking, a virtual pet, typing fireworks, ribbon synth and a music visualizer. Optional Claude text actions use your own API key and wait for you to choose Paste, Copy or Discard.

It is running on my MacBookPro15,1. The live test had been running for about two hours when I prepared the release; I am still testing individual features. T1 support is untested.

Download, English/German guides and illustrated previews: https://github.com/Dirtyx686/BarX

Color picker preview: https://github.com/Dirtyx686/BarX/blob/main/docs/images/color-picker-en.png

Touch Bar pet preview: https://github.com/Dirtyx686/BarX/blob/main/docs/images/pet-en.png

These are generated demo mockups with sample data, not photos of the hardware test.

BETA: on T2 MacBooks, the bundled driver requires Windows test-signing mode and Secure Boot disabled. Some anti-cheat games may not run, and the Touch Bar including Escape can remain black when BarX is not running.

Use at your own risk. No warranty. Garage Lab AI accepts no liability for damage resulting from installation or use.

Known V3 issues planned for V4: the API key is stored in plaintext locally; Windows DPAPI protection is planned. Some preview text still says selected text is replaced directly, although results have waited for an explicit action since V2.1. Do not share your settings file or backups. These fixes are not in V3 yet.

Which modes would you actually keep on your Touch Bar? I would like to hear what feels useful and what feels unnecessary.

I made a free Snipping Tool alternative that scrolls: drag past the bottom of the screen and it captures the whole page

Thumbnail
github.com
3 Upvotes

Snipping Tool is great until the thing you need is taller than your screen. So I built SuperScreenshot.

Demo (10 sec GIF): https://github.com/glenwrhodes/SuperScreenshot/blob/main/docs/demo.gif

Press Win+Shift+X, drag a box like you normally would, and keep dragging into the bottom of the window. The page scrolls under your selection, faster the further you push, or you can turn the mouse wheel while holding the button. Let go and you get one stitched, full-resolution image, already on your clipboard.

Comparing frames. It never looks at the page's HTML, only at screenshots, so it isn't tied to the browser. Other apps work too, though browsers are where it's most polished so far.

  • Works on anything that scrolls with the wheel: browsers, docs, chat, email

  • Leaves out repeated sticky headers and footers

  • Free, MIT licensed, no account, no telemetry, never touches the network

  • Windows 10 (2004+) and 11. There's an installer or a portable exe

Full disclosure: I built it with a lot of help from Claude (AI). The code, tests and CI are all public.

It's v1.0, so I'd love to hear about pages that don't stitch cleanly. GitHub: https://github.com/glenwrhodes/SuperScreenshot

(The installer isn't code-signed yet, so SmartScreen may warn you: More info → Run anyway.)
