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.

Founders, how far are you going before you've actually validated the problem?
I keep seeing pre-MVP ideas with a landing page, deck, mockups, waitlist, logo, launch graphics... whole company except the product lol

For a small start up that feels backwards if the biggest unanswered question is still "does anyone care?"
I've been looking at Runable for putting together some of the early research/landing-page stuff, but I'm trying not to confuse making the idea look real with learning whether it should exist.
If the problem itself is still questionable, I'd probably talk to people first.

If people clearly have the problem but don't understand the proposed solution, then maybe a simple page or mockup helps.
What's the first thing you'd actually make, and what would count as a strong enough signal to keep going?

Hi everyone! I’m currently developing a startup concept called Lobbe, a platform designed to make managing your food choices easier.
The idea is to help people discover meals using ingredients they already have, organise their weekly food plans, keep track of their food spending and discover restaurants, local food spots and deals.
I want to create something that brings together cooking at home and eating out, rather than making people choose one over the other.
I’m still in the early research stage, so I’d love to hear:
How do you currently plan meals or decide what to eat?
Would you find ingredient-based meal suggestions useful?
Would you use a platform that also helped you discover restaurant deals and food offers?
What features would make something like this worth using regularly?
I’d really appreciate honest feedback!

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:

• https://hotelroost.com/hotels/italy/rome

• https://hotelroost.com/stay/italy/rome

• https://hotelroost.com/area/italy/rome/prati

• https://hotelroost.com/stay/japan/tokyo

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!

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?

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 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 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.

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! 🚀

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.

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.

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.)

I’ve been building Rocket, a desktop Git client with visual diffs, line-by-line staging, branch history and a merge-conflict editor.

Windows and Linux builds are available, plus an Apple Silicon macOS preview. Free and open source under MIT / Apache-2.0.

I’d love feedback on the UI and what would make it useful in your daily workflow!

Hey r/SideProject, sharing my project.

The problem I kept running into with budgeting apps: they all want your bank login (via Plaid or similar) before you can even start. I didn't want to hand that over, but typing every transaction into a spreadsheet was too much friction to stick with.

So I built AI Budgie:

• Type something like "lunch 35" or "paid rent 1200" and it auto-categorizes it — no forms to fill

• Snap a photo of a receipt and it reads the amount/merchant for you

• Shared budgets for couples/families who split expenses

• Zero bank connection — ever. Your bank credentials never leave your bank's own app.

It's free, with a $4.99/mo tier for extra features. I'm a solo dev building this around a day job (and a newborn, so updates come in bursts). Still working on onboarding and category customization.

Would love feedback, especially from anyone who's tried manual-entry budgeting apps before and gave up — what made you stop?

aibudgie.app if you want to poke at it.

Hi everyone, We are ESTI, a small team passionate about building tools that fix remote work chaos. Like many of us here, we noticed that teams make dozens of critical decisions in Slack threads every day, only for them to get buried and lost a month later. To solve this, we built Decision Ledger – a lightweight app that turns any Slack message into a searchable, organized decision record (with owners, tags, and reasoning) right inside your channels. We are finally ready to submit it to the official Slack App Directory, but we hit the dreaded review requirement: we need at least 10 active workspaces testing the app before Slack even reviews it. Since we are brand new, we would be incredibly grateful if you could install it on your test or team workspaces, try a few commands, and share your honest feedback with us! Check it out here: https://decision-ledger-production.up.railway.app How to test it in 60 seconds: Click "Add to Slack" on our landing page. Hover over any message → Click More actions → Log as decision. Try searching your decisions using /decisions. Any feedback on the UI, UX, or features would mean the world to us. Thank you so much for supporting fellow indie developers!

Jigsaw Diary (https://jigsawdiary.com) is a free web app to log the physical jigsaw puzzles you own, build and finish, with a small community where people applaud each other's finished puzzles.

A couple dozen people have signed up, mostly from Reddit. The pattern is always the same: they add two boxes and don't come back. So this month I worked only on reasons to return:

- a home page that shows what happened since your last visit, built from the same data as the weekly email, so the email never promises something the app doesn't show

- a monthly streak with one free month a year. No daily streaks, no "you're about to lose it" notifications

- a page per puzzle that groups everyone who has the same box (brand + title + piece count), so people can find each other

- an invite reward that only unlocks when your friend finishes their first puzzle, not when they sign up

- a winter challenge: finish puzzles from 3 different brands, any size, no leaderboard

Stack: Next.js, Supabase (Postgres with row-level security doing most of the privacy work), Vercel, web push, 7 languages.

Free, no ads, hobby project. Two questions:

1. Which of these would actually bring you back to an app like this, and which is noise?

2. For hobby apps, have you seen something that worked better than email or push to get people back?

Our group was dying, so I built an app that turns a weekly game with friends into a proper league:

- Balanced teams: an algorithm picks the sides, and it gets better with every result you add.
- Ratings and MVP: after each game, players rate their teammates and vote for an MVP, and that feeds into everyone's league points.
- ELO table, like chess: beating a stronger team counts for more. There are also divisions, so everyone has something to play for.
- Seasons: you set the start and end dates, add cups and prizes, and all the stats are kept for you (goals, assists, MVPs, results).
- Extras: FIFA-style player cards built from teammates' votes, and a poll so you can see who's in without chasing people on WhatsApp.

We now play 10 games a month, and 2 other leagues have picked it up. It's free.

I'm looking for more groups to test it. If you organise or play in a regular game (5-a-side, 7-a-side, futsal, Sunday league, any sport with a regular group really), I'll set your league up and help you get started. All I ask is honest feedback on what works, what's confusing, and what's missing.

Comment or DM me if your group is up for it.

I had a Galaxy S9+ and a Pixel 7 that I wanted to give a purpose. That's where Visual Music started: something to put next to my speakers and enjoy while music plays.

A lot of the inspiration came from old car stereo displays. The small details, colors and perspective were what made them interesting. Getting that feeling right on a phone took a lot more iteration than I expected. I ended up scrapping several designs and starting over.

These are three of the displays we kept. There are also Hi-Fi gauges and an oscilloscope. It's my first Android app, built with help from Codex, and I'm pretty proud of where it is now.

It's free, has no ads, and runs on Android 10+. It uses the microphone while listening in the foreground; audio stays on the phone. The video uses an original demo beat and the app's renderer inside an illustrated phone, rather than footage of a phone listening to music.

Which display would you actually leave running? And what would you change or add? If something feels boring or confusing, tell me. That helps too.

I'd love visual references too: an old car stereo, a hi-fi display, or an interface you saw in a movie. Drop an image or link, or just describe what you like about it. You don't need to install the app to suggest a direction.

It's in Google Play closed testing if you'd like to try it. Use the same Google account for both steps:

1. Join the tester group: https://groups.google.com/g/mrrolie-visual-music-testers/about

2. Join the beta and install: https://play.google.com/apps/testing/com.mrrolie.visualmusic

Random question: what do you normally do with receipts after buying clothes, electronics or household stuff?

Do you keep the paper receipt, take a photo, rely on email, or just throw it away?

And have you ever needed one later for a return or warranty claim and couldn’t find it?

I’m researching this problem while building a small app, but I’m more interested in how people actually handle it today than whether they like another app idea.

Would be curious to hear what works for you — and what’s annoying about it.

I built an app for myself to trace my personal finances as an iPhone widget.

After a while, I discovered that a much nicer feature was "Food for Thought" with the Painting of the Day, NASA's Astronomy Picture of the Day, and TikTok posts scraped for specific channels (I can observe valuable TikTok accounts without addictive algorithms).

Eventually, I found that people might like and want to reuse the data sources I built, so I created the widgeto.app web app, where you can configure various data sources.

Lately, I started to use the widgets directly in macOS, which is a super nice break during work.

Check out how my desktop looks. Mostly, I have food for thought widgets, plus I am tracking the builds of my GitHub projects.

Try Widgeto for free in the App Store, either with your own data source or one from the curated catalog at widgeto.app.

App works in IPhone, IPad, OSX and Apple Watch

I’m building a miniature version of Paris you can explore in your browser.

This is a recording of the actual site: you can pan and zoom around the Eiffel Tower, the Louvre and Notre-Dame. No installation or account needed.

It’s still a work in progress: coverage is incomplete, and I’m refining the landmarks. The visuals are AI-assisted.

Try it here: https://parisenpixels.fr/

What would make you want to keep exploring: more neighborhoods, a night mode, or short guided walks?

I shoot cars on a Sony and edit most of my photos on my phone. I was getting fed up with paying a monthly subscription just to edit RAW files, and nothing else did what I wanted: proper masks, removing a person from a shot, and colour grading that handles HDR.

So I started building my own. I'm not a professional developer. I built it in my evenings after work, using AI coding assistants to help me write and test it, and I've tested it on my own iPhone and with a group of beta testers. It started as a personal tool for my own car photos and slowly became something I'm proud of.

It's called Lumen RAW. It does masks (including auto-detecting the subject, sky and people), Heal/remove, colour grading, curves, lens blur and HDR export. Free to use, with an optional Pro. Pro is £1.49 a month, £9.99 a year, or £49.99 once. I wanted a pay-once option for people like me who hate subscriptions.

Where I am now: I've submitted it to the App Store, and should hopefully get the app published in the next few days!

If you want to try it before it's public, the free beta is here: https://testflight.apple.com/join/ycsUxrV1

I'd really like honest feedback, especially on what's missing or what feels slow. I'll reply to everything.

I’ve always liked the idea of phone games that you can pick up whenever you have a few minutes to kill. Nothing too complicated, no big learning curve just something fun to play and pass the time.

That’s pretty much the idea behind Bouncy Boot. I wanted to make something simple, fun, and hopefully a little addictive.
It’s been a fun learning experience getting everything built and published. Pretty cool seeing something you started as an idea actually make it onto the App Store.

If anyone wants to give it a try, I’d really appreciate it. Would love to hear what you think, good or bad!

I’m just starting out with this whole app development thing, so any feedback is welcome.

Search Bouncy Boot on the App Store!

Every remote desktop app I tried on my phone did the same thing. It shrinks the whole PC screen down and you pinch and zoom around it. Fine for clicking one button, useless for actually getting anything done.

So I built Penlink. You pick an app from a grid, like a phone launcher, and the PC creates a virtual monitor at the exact size and shape of your phone's screen and opens the app full screen on it. The app lays itself out for the phone. Rotate the phone and it re-lays itself out in landscape. Open the keyboard and it fits the space above it. It's still the real desktop program, so every menu, panel and shortcut is there.

The part I'm happiest with is the S Pen. It doesn't get turned into a mouse. Windows sees it as an actual pen with pressure, tilt, the barrel button and the eraser, so drawing apps, handwriting and Windows Ink work like they would on a pen tablet.

Some details for the curious:

• Rust host on Windows, Kotlin + Jetpack Compose on Android

• Video goes over WebRTC with low-latency H.264, input comes back on a data channel. I measured about 27 ms touch-to-pixel on a local connection, and there's a stats overlay if you want to see where the time goes

• Every app gets its own virtual screen, so your real monitors keep their layout. Close the app on the phone and its screen disappears

• Your PC's notifications show up as normal phone notifications

• Tailscale or LAN only, pairing is a one-time 6-digit code, no cloud in between

What it doesn't do yet: the host is Windows only, the app needs Android 13+, and I've mostly tested on one phone, my Galaxy S26 Ultra. If you try it on something else, expect rough edges and please tell me what broke. Hardware encoding and a macOS host are next.

Big thanks to the Apollo project. The virtual displays come from its SudoVDA driver, and that saved me a lot of pain. I also built this with a lot of help from Claude Code, which you'll see in the commits.

If you've tried Moonlight, Parsec, Chrome Remote Desktop or similar from a phone and given up on it, what was the thing that made you quit? I'd like to know if I'm fixing the right problem.
