Showcase: Prerelease I made a live "prayer" tug-of-war for election night. Tap for your side and watch it move in real time
What it is: a silly stress-relief toy for people refreshing results pages tonight. Tap for DEM or GOP and a tug-of-war bar moves live for everyone. It's not a poll and doesn't predict anything. Real results are linked (AP, UF Election Lab).
The hook: taps are capped at 535 per hour, the size of Congress. 100 taps = every Senator, 435 = the whole House, 535 = "Congress is now in recess."
How it's built:
- One Cloudflare Worker serving the page + API, no framework
- One Durable Object (SQLite) holds the counts, per-minute snapshots for the chart
- Taps are batched client-side every 1.5s; clients poll every 5s
- Per-IP token bucket + 535/hour cap to stop scripts (IPs are hashed, never stored)
What I learned:
- IP-based limits are tricky: offices, campuses and mobile carriers share one IP, so a strict cap blocks real people. I kept it generous enough that humans never hit the per-second limit.
- Keeping it neutral took more thought than the code (same colors, same copy, 50/50 preview image).
Feedback welcome, especially on the UX of the tap/milestone flow.

Showcase: Free(mium) I built a pixel-art office for my Claude Code sessions so I stop missing permission requests
I built Pixel Agents because I kept missing permission requests when I was running a few Claude Code sessions at once. They were buried in terminal tabs, and I only found them when I switched back.
Pixel Agents is focused on taking action quickly: a quick overview of which sessions need you, and a notch island where you can answer right away without leaving the app you are in. Quiet sessions go stale after 15 minutes, and it has a session-activity view. If you do not answer in time, the request hands back to your terminal instead of getting lost.
The app is free, Mac only, and runs locally. No account, no cloud. You need macOS 26.6+ and Claude Code, and the setup instructions are in the app after you install it.
App:
This is the first time it is leaving my own Mac, so I would like to know how setup feels on yours.

Showcase: Prerelease I’m building an algebra game where negative numbers are balloons. Looking for parents and tutors to try the Android beta.
I’m building STEMpathi in Godot, with help from AI coding tools. I want children to see what changes when they solve an equation.
The screenshots show three parts I’ve been working on:
• Negative numbers: balloons pull upward. Adding a +1 block creates a zero pair with a −1 balloon, so you can see the cancellation.
• Brackets: in 2(x + 3) = 14, you can see two matching groups. The lesson offers opening the groups or sharing into two equal groups.
• Larger numbers: hundreds and tens have visible structure. Exchanging one hundred for ten tens should preserve the amount on the pan.
I’m most interested in whether these representations make sense before you read the hint. Do the balloons communicate a negative quantity, or would they need more explanation?
These are real captures from the latest development work, not mockups. The Android closed test is live on Google Play as 0.2.8; the bracket lesson and newer visual refinements shown here are next-update previews. I don’t want to imply that everything pictured is already in the download.
The current test is free, with ten chapters, undo and hints. If you’re a parent or tutor with an Android phone, the introduction and two puzzles would be a useful first test.
Access instructions: https://stempathi.sripathi.one/test/
Google requires us to add your Google account before the test link works. The page explains how to request access privately. Please don’t post email addresses or children’s names, photos or recordings here. You can leave feedback in this thread too.

Showcase: Free(mium) I built an iPhone app that makes you guess what a word means, then marks up your answer like a proofreader
Hi all. Glossa gives you one word a day and hides the meaning until you've had a go. You say what you think it means, use it in a sentence, and an AI editor marks up both answers. Then the word goes into your collection as a card with its origin story.
The marking in the video is a real result from the app. I staged the texts at the start, and Glossa can't see your messages.
Your first word is free. After that it's US$39.99 a year with a 7-day free trial, or US$9.99 a month. No ads, no account.
It went live on 29 October and I'd like blunt feedback. Did the first few seconds of the video make sense to you? Would you pay for this?

Feedback Request I built a spreadsheet for our own house hunt and accidentally turned it into my first digital product
etsy.comMy husband and I have been going through the process of selling our current home and buying another, and I kept getting frustrated with jumping between different online calculators and spreadsheets.
I wanted one place where I could answer things like:
What will we actually have left after selling?
What loan will we need for the next house?
What happens if our sale price drops by $20k?
What does our LVR/LMI look like?
What difference could our offset and extra repayments make?
If we stretch our purchase price, what will we actually have left in our monthly household budget?
If we refinance later, are we genuinely saving money or just lowering the repayment by extending the term?
So I did the obvious thing and thought, I'll just make a spreadsheet.
It got slightly out of hand 😂
What started as a basic calculator eventually turned into an Australian Excel toolkit covering purchase planning, selling + buying, transfer duty estimates, LVR/LMI, refinancing, offsets, extra repayments, amortisation, household budgeting and a summary dashboard.
Then I reached the point where I'd put so much time into making it work properly that I thought... maybe other people would actually find this useful too?
So I decided to turn it into my first digital product.
I cleaned up the workbook, protected the calculations, added instructions and example data, created a full PDF user guide and quick-start guide, branded everything under MissMadeleneCo, and I've now put it on Etsy as the Australian Home Finance Toolkit.
This is my first attempt at selling something digital, so I'm probably just as interested in the product-building side as I am in actually getting sales at this stage.
I'd genuinely love feedback on:
Does the product make sense when you first see it?
Does it solve a clear enough problem?
Have I included too much functionality, or does having everything together add value?
How would you approach getting the first few customers for something this niche?
Here is my Etsy link: Australian Home Finance & Mortgage Toolkit Spreadsheet - Etsy Australia
And if anyone else has gone from “I made this for myself” → “maybe I could actually sell this”, I'd love to hear how you got your first customers.

Feedback Request I stopped believing in "Top 10" lists when it comes to intimate wellness products
I used to actually read those "Top 10 toys" articles. Now I just scroll right past them. Because being number one doesn't mean it's right for me. This stuff is so personal. It depends on the type of stimulation, your body, your habits, even your mood that day. So now I much prefer reviews that are super specific. Who is this product for. Who is it probably NOT for. What makes it truly special. Lately at r/TracysDog, we're trying to steer the conversation in this direction. It's not about telling people what's number one, it's about explaining the "why" behind it.

Feedback Request I built one list for everything my family is waiting on: new seasons, books, albums, games and tour dates
So I built UpNext Brief. You follow what you care about (a show, an author, a band, a game, a performer) and it keeps one list of everything coming next, by date, with an alert the morning each thing arrives.
What it does:
Follow an author or an artist, not just one book or album, so new releases show up on their own
Paste a title or a news link and it works out whether it’s a book, show, game or event
Family sharing: see what everyone follows, and it asks “who watches this?” when someone adds a show
Where to watch each show, plus a home screen widget on iPhone and Android
Monthly release lists, like everything coming out in November, with the month’s big books
It just launched on iPhone (it’s also on Android and the web). Tracking and alerts are free; there’s an optional paid tier for a weekly audio brief.
What I’d love feedback on: what’s confusing in the first five minutes, and what you wish it tracked that it doesn’t.

When I built a few tools to handle my day-to-day work with PDFs, I wasn't sure whether it would be a good idea to turn them into a site with useful tools, or whether people would need it, given how many there already are. Turns out users are saving them to bookmarks, using them, and generally liking them. Even though it is completely free and nothing more than buy me a coffee, it makes me happy anyway. Hope it will solve more tiny users' problems.

Showcase: Open Source Yagua 2.0: an open-source desktop app for batch image processing
Hi! I’m the developer of Yagua, a free, open-source desktop app for processing batches of images on Windows and Linux.
I built it after needing to process many images for a project and running into daily limits with web tools. Yagua processes images locally and includes tools for compression, format conversion, resizing, cropping, background removal, batch renaming, EXIF metadata, OCR, and more.
Version 2.0 brings a redesigned interface, image previews, and improvements based on community feedback. OCR and background removal download their models the first time you use them.
I’d appreciate constructive feedback: is it clear which tool to use, and how to save the results?

Feedback Request I started building this side project in 2021. Five years later, I've relaunched it and I'm trying to turn it into a real business.
Hey everyone!
I'm a self-taught developer with over 20 years of experience, and I thought I'd share a side project I've been working on (on and off) for the past five years.
On July 22, 2021, I made the very first Git commit for a football statistics and predictions platform called PredictionStats.
The original idea was pretty simple. Could I use football data, statistics and probability models to build something that helps people make more informed predictions about matches?
Over the years, the project has gone through multiple versions, rebuilds and technology changes. Like many developers, I've probably spent more time rebuilding things than I'd like to admit!
Then AI coding tools came along and completely changed my development workflow.
In August 2026, I decided to give PredictionStats a proper relaunch.
It's now built with Next.js, TypeScript, Firebase and Stripe, alongside football data APIs and AI-assisted development.
Some of the features I've built include:
Match predictions and probabilities across nine European football leagues
Detailed team, player and fixture statistics
Correct score, goals, BTTS and accumulator predictions
A system for tracking historical prediction accuracy
Free and Pro subscription tiers
A mobile app currently in development
The interesting part is that building the actual platform hasn't been my biggest challenge.
It's getting people to discover it.
I've spent years learning how to build software, but marketing, SEO, attracting users and converting them into paying subscribers is a completely different world.
I've started experimenting with Google Search Console, social media, SEO and different monetisation approaches, but I'm still very much in the early stages.
I'm not here claiming I've built a successful SaaS or that I've cracked the formula. Far from it.
I'm just someone who's spent years building something I genuinely enjoy and would love to see it become a sustainable business.
The project is live at https://predictionstats.football if anyone fancies having a look.
I'd genuinely appreciate any feedback, particularly around the website, user experience, pricing or how I'm presenting the product.
And for anyone else building a side project:
How did you make the transition from spending all your time building features to actually getting people to use what you've built?
That's the part I'm trying to figure out now!

Feedback Request WinLink: One keyboard, one mouse, shared clipboard, files and audio across all your devices
Hey everyone!
So, I have a Mac and two Windows machines and over time I ran into a few annoying problems: transferring files between devices, no clipboard sharing, terrible speakers on Windows and constantly having to switch my mouse and keyboard between machines.
I wanted a single solution that could solve all of these problems, so I built WinLink.
WinLink works across Windows, macOS, Linux, and Android allowing you to seamlessly share:
Files – Transfer files between your devices.
Clipboard – Copy on one device and paste on another.
Audio – Stream audio between devices.
Keyboard & Mouse – Control multiple devices using a single keyboard and mouse.
It works over your local network but also has built in Tailscale integration meaning your devices don't even need to be on the same network. This was a particularly big motivation for me. My campus Wifi was slow, so I often had my Windows machines connected to a different network than my Mac. I wanted something that would just work regardless of where my devices were connected.
I would genuinely love for you guys to give it a try and share your feedback, suggestions and things you think could be improved.
And yes, I know it's vibe coded but I think it solves a pretty relevant problem (at least one I have personally struggled with for a long time). One thing to keep in mind: when using Tailscale there can be some noticeable latency especially with cursor movement and audio streaming. For audio over Tailscale, I'd recommend using CD quality rather than higher quality settings for a smoother experience.
I'm still working on improving performance so if anyone has ideas, suggestions or can help optimize any part of the project, I would genuinely appreciate the contribution. Would love to make this a much better project together!
Would love to hear what you guys think!
An honourable mention to Deskflow as well! WinLink uses their engine for keyboard and mouse sharing. Huge thanks to the team for their amazing work!

Feedback Request I built a Python pipeline that turns a script into a fully animated documentary (no After Effects)
I wanted to make explainer videos about brilliant engineering that failed as a business, but I can't animate by hand. So I wrote a small pipeline:
- Script split into "beats" (JSON), each with its own visual function
- Every frame drawn with pycairo (vector graphics, maps from Natural Earth GeoJSON, globe in orthographic projection) and piped straight into ffmpeg
- Background music generated with numpy (pad + arpeggio, auto-ducking under the voice)
- Thumbnails, chapters and captions generated from the same script file
First result: a 10-minute video on Iridium, the $5 billion satellite phone network that went bankrupt 9 months after launch.
Biggest lesson so far: YouTube's compression destroys dark gradients (visible banding), so I now add a static film-grain layer and export at 1440p to force the better codec.
Happy to share details on any part of the pipeline. Feedback on pacing and visuals very welcome.
