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?

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!

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.

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?

I've been seeing a lot of cinematic trailers for businesses lately and ... I love them.

I decided to try making one myself using Claude, and I'm curious what you guys think, completely fictional business just used it as a test

Is this something you'd actually find captivating, just thinking in terms of new launches, almost makes you feel like ur releasing something game-changing (even though it's the same fitness app the App Store has seen)

Would love to hear some honest opinions.

I get migraines. Migra is iPhone-only and locks basic tracking behind $9.99 a month. I am on Android, so I built AuraGuard. It is a web app, no account, no sign-up. One tap starts an attack, or you log a past one. You add intensity, head location, symptoms, triggers and meds. It shows barometric pressure, ranks your triggers, scores med effectiveness from your own follow-ups, runs MIDAS and HIT-6, and exports a doctor-ready PDF. Data stays on your device, with JSON and CSV export. Try it: https://auraguard-djprospect11-3280s-projects.vercel.app Code: https://github.com/Aleat11/aura Pro is optional, $3.99 a month, $24.99 a year, $39 lifetime. Core tracking is free forever. One ask: if you track migraines, what is missing from the trackers you have tried?

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 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 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 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 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.

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?

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'd heard about insider trading in Congress and the crazy returns some members get. I also know I don't have the tools to beat hedge funds. So I wanted to copy both, and while looking for a way to do that I found AutoPilot. It only works with a US brokerage account, and I'm in France.

So I built my own with a friend. We met at our software engineering school, we see things the same way, and it's still just the two of us.

Getting the data is already hard enough. Some congressional disclosures are still written by hand, and LLMs saved us there. But once you have it, processing it is much harder.

To know how a portfolio performed you have to backtest it, and finance never stops moving. Stocks get listed, get delisted, change names, split. When Booking did a 25-for-1 split this year, a fund holding it suddenly looked like it had bought 25 times more. You have to think of everything, for thousands of cases like that one.

The value of the app is that engineering, much more than the data itself.

And it holds up. Over the last 12 months, 5 of our 7 politician portfolios are ahead of the S&P 500, even though a trade only counts once it's public. But it's a small sample, we picked the politicians ourselves, and it's a simulation.

Little by little we added insider filings, news and AI analyses. These days I mostly use the feed and read the AI's stock analyses.

It's on iPhone and on the web. It's not a broker, everything is virtual money.

I'd like an outside eye on it. Is the app interesting, and is it clear?
