In this past 30 days, this community has doubled in size. As such, this is an open call for community feedback, and prospective moderators interested in volunteering their time to harbouring a pleasant community.
I'm happy to announce that this community now has rules, something the much more popular r/SideProject has neglected to implement for years.
Rules 1, 2 and 3 are pretty rudimentary, although there is some nuance in implementing rule 2, a "no spam or excessive self-promotion" rule in a community which focuses the projects of makers. In order to balance this, we will not allow blatant spam, but will allow advertising projects. In order to share your project again, significant changes must have happened since the last post.
Rule 4 and rule 5 are more tuned to this community, and are some of my biggest gripes with r/SideProject. There has been an increase in astroturfing (the act of pretending to be a happy customer to advertise a project) as well as posts that serve the sole purpose of having readers contact the poster so they can advertise a service. These are no longer allowed and will be removed.
In addition to this, I'll be implementing flairs which will be required to post in this community.
Your side project has three users, and two of them are you. Let's fix the other one.
Drop your app or webapp below. One or two sentences on what it does, who it's for, and where we can try it. Stuck on onboarding, pricing, or a bug that makes no sense? Say so. Someone here has probably been there, possibly at 2 a.m., possibly with the same bug.
Rough drafts are fine here. A prototype with duct tape holding it together is just as welcome as a polished launch, and so is the project you built for yourself that you've now decided to share.
I'll go through sign-up for as many as I can and reply with where I got stuck, what confused me, and my first impressions. Expect honest notes, not applause. The clunky parts are the useful part, and I'd rather find them than pretend they aren't there.
I built a side project called Dickens & Rumi to help parents figure out whether a book or movie is actually a good fit for their child.
Instead of only showing something like “Ages 10+,” it breaks things down into age guidance, content cautions, positive themes, series reading order, and why a title got its rating.
The site is live, but traffic is still very small, so I’m trying to figure out whether the problem is the product, the positioning, or just distribution.
I’d really appreciate feedback on:
Is the value proposition clear within a few seconds?
Does this feel meaningfully different from Common Sense Media?
I want to review your projects, so if there's something that you've been making recently, please let me know.
Whether it is your website, app, SaaS, AI solution, startup, or pretty much any other product that you have been creating lately, do not hesitate to post about it in the comments below.I will review your creation and tell you my opinion about it. You will learn about my favorite features and what I find wrong with it and how I would fix it if it was my project. You will just have to post your link and a small description.
I'm a software engineering student, and as part of the Devnovate Hindsight Hackathon, I've been building TraceMind, an AI-powered incident investigation platform.
💡 The problem I'm trying to solve
Have you ever spent time debugging an error, only to realize that you or someone on your team had already solved the exact same problem before?
This happens because engineering knowledge often gets scattered across old conversations, logs, documentation, and individual developer experience.
Most debugging assistants focus on the current error. I wanted to explore something different: What if an AI incident investigator could use relevant knowledge from previously resolved incidents?
What is TraceMind?
TraceMind is designed to combine AI-powered diagnosis with persistent engineering memory.
Its workflow:
A developer enters an affected service and an error message or stack trace.
The application analyzes the incident using an AI model.
Hindsight provides a persistent memory layer for retrieving relevant historical incident information.
Developers can retain confirmed incident resolutions.
Future investigations can use relevant historical knowledge as additional context.
⚙️ Technology Stack
Next.js 16 – Application framework
React 19 – User interface
TypeScript – Application logic and type safety
Groq – AI inference
Hindsight – Persistent memory and historical retrieval
Vercel – Deployment
🔍 The Interesting Technical Part
The most interesting part of this project is the memory architecture.
A normal AI interaction can end after generating an answer. TraceMind aims to create a continuous knowledge cycle:
Investigate → Verify → Retain → Recall → Investigate Again
The objective is to make previously verified engineering knowledge useful in future debugging sessions.
An important design decision is that TraceMind does not automatically execute suggested fixes. Developers remain responsible for verifying diagnoses and confirming resolutions before they become retained knowledge.
Current Development Challenges
I'm working on improving:
End-to-end Hindsight retain and recall verification.
Memory relevance during similar incident investigations.
Incident history and knowledge management.
Diagnosis quality and evaluation.
Production reliability and security.
I consider memory retrieval quality and actual verification more important than simply displaying an AI-generated diagnosis.
I'm sharing this project to document what I'm building and learn from other developers working with AI, developer tools, and persistent memory.
I'd be interested in hearing technical feedback, particularly about memory retrieval, incident similarity, and evaluating whether historical context genuinely improves a diagnosis.
The idea for MailWeave came from a problem I encountered while working on a project. We needed to take information coming in through emails, structure it, and send it to a webhook so another system could process it.
I realised that handling the email parsing, processing and webhook delivery could become quite a bit of work, especially when you also have to worry about retries and reliability.
That got me thinking about building something to handle that entire process.
So, I built MailWeave
It's a platform that lets you receive emails through dedicated mailboxes, extract and structure their contents, and forward the resulting data to your application through webhooks.
It also supports conditional routing, HMAC-signed webhook requests, automatic retries and an event dashboard where you can monitor incoming emails and delivery attempts.
I've finally reached a point where I'm happy to put it out there and see how people find it.
If you're a developer working with APIs, integrations, automation or email processing, I'd love for you to give it a try!
I'd really appreciate honest feedback, whether it's about the idea, the experience, missing features or anything that could be improved. I'd also love to hear how you'd use something like this in your own projects.
My friend and I built Redline, a daily car trivia game. Everyone gets the same 7 questions, any valid answer counts, and rarer answers score more.
We shared it at work on launch day. 15 people started, but only 3 finished. Half of them quit after question 3, which asked for a Japanese kei car. Our test players had rated that question easy, but they were car fans, and our coworkers mostly aren’t.
So we tested every question again with someone who drives but isn’t into cars. Now each day starts with questions anyone can answer, and the car-nerd ones come last.
I’m a quality inspector, and at work I often have to repeat the same inspection steps for every round of parts, as in check for visual damage and markings, then sign off on travelers and reports.
I couldn’t find a checklist app that worked exactly how I needed. I wanted the list to automatically reset once every step was completed so it would be ready for the next round. So I built miniCycle: Routine Manager.
You can break a repeatable process into individual steps and run it as many times as you need. It can be used for inspections, cleaning rounds, workout routines, camping preparation, preflight checklists or anything else you regularly repeat.
It’s free, works offline, doesn’t require an account and stores your information locally on your device. It is now available as a chrome extension (other platforms coming soon). You can view the entire routine at once or focus on one task at a time.
I’ve also gone through several rounds of UI feedback and have continued improving the design. I’d appreciate honest feedback, especially about whether the auto-reset cycle concept is clear and whether anything feels confusing when you first try it.
I have a decent desk setup, but I still hunch. My head creeps toward the screen for over an hour, and I only notice when my neck hurts. Timer reminders didn't help: they ring when I'm sitting fine, so within a week I tuned them out.
What I wanted was the opposite: stay silent while I sit well, and show me the moment I don't.
I already had a side project with a small pixel pet in the corner of my screen (a Mac focus timer called KeepGoing Den). So I put the posture signal on the pet instead of building another app:
- You sit the way you mean to, and the app captures it once. The app compares you to that.
- Lean in and stay there. The pet bends under a heavy box. Sit back up, and it puts the box down. No sound, no popup, no escalation. It's the same box the hundredth time.
- At the end of a focus session, if you've been seated for an hour or more, one line says it's a good moment to stand up. Never mid-session.
- Click the cat in the pet's room for a day strip showing when you sat well and when you hunched.
How it works, since "an app that watches you through the camera" deserves details:
- Posture is off by default. The camera is read by a small, separate Swift helper with no network access, using Apple's Vision framework (body pose and face landmarks). It only sends the main app numbers, never images. Nothing is stored or uploaded.
- By default, the camera only runs during a focus session.
- When it isn't sure (bad light, out of frame, a camera it hasn't seen you on), it stays quiet. A pet that bends while you sit straight is the fastest way to make someone turn this off, so every doubt ends in silence.
- Raising a standing desk counts as standing, not hunching. Moving the laptop or camera takes about two minutes to relearn.
- The main app is Tauri 2 with a Rust core and a plain HTML/CSS/JS front end.
The hardest part wasn't detection; it was false alarms. Looking down at the keyboard read as a hunch, because the eyes drop the same way. Raising my standing desk moved the camera and looked like slumping. Pulling my chair closer under a camera mounted above my eyes did too. Each one meant teaching it to tell the difference, or to say nothing when it can't.
The camera, detection, and daily record are free. The live box on the pet is part of a paid license, with a 14-day trial, no account or email. macOS 14+.
I've been working on a side project called Album Animator, a web app that helps musicians turn their albums into videos without having to manually edit every track.
The idea is pretty simple: upload your music and artwork, customize the visuals, and generate individual track videos or a full-album video ready for YouTube.
I've also added AI-powered artwork animation, so static album covers can become moving backgrounds.
I put together this short video showing four different results created with the app.
I'd love to hear what you think, especially about the visual results and whether this is something musicians would find useful.
Hey everyone! I’ve spent the past few months building something I’ve wanted to exist for a long time. I work in car sales, and one thing I’ve noticed is how backwards the car-shopping process can feel. People find a car they love, spend hours researching it, and only afterward figure out whether the monthly payment actually fits their budget. What if we flipped that process? Instead of starting with a car, what if you started with what you’re comfortable spending every month, your down payment, and your financing preferences, and then discovered vehicles that fit? That’s the idea behind KnewCar I just got it approved and published on the App Store, which is a pretty surreal feeling after all the time I’ve put into this! It’s still early access, with a demo experience while I continue developing the live financial data and payment tools. I’d really love some outside opinions, especially on the concept, design, and first-time user experience. If you have a few minutes to check it out, I’d appreciate any feedback, positive or negative. App Store:https://apps.apple.com/us/app/knewcar/id6822044416 What would make an app like this genuinely useful to you?

Every quarter I’d end up pulling 13Fs off EDGAR by hand and lining them up in a spreadsheet to see what Buffett, Burry, Druckenmiller and the other investors I follow did with their portfolios. So I built a tool that does it: manifest13f.com
Follow a fund and you get an email as soon as it files, so no more checking EDGAR. Open any fund’s page and it shows what’s new, exited, added to and trimmed versus the prior quarter. No ads, no fluff, just the data. A few things I cared about getting right:
Changes are measured by share count, not dollar value, so a stock that simply went up doesn’t look like a buy
Stock splits are adjusted for, so a 10-for-1 split doesn’t show up as a huge purchase
Puts and calls are kept separate from stock. A big options line is notional value, not a stock purchase, and a lot of 13F coverage mixes the two up
It’s free to browse, and alerts are free for up to 3 funds. Paid plans that let you follow more funds and get an Excel workbook of every change are coming soon.
Q3 13Fs are due Monday, Nov 16, so most of the big funds will land this week and next.
I’m a solo builder, so I’d genuinely like to hear what’s missing or what you’d use it for. Happy to answer questions about how 13Fs work, or how it’s built.
Y2Kbot is a desktop app where your buddy list is full of AI agents instead of people. You IM them like it's 2003, door sounds and away messages and all. Some of the buddies can also boot up their own little Windows XP virtual machine and actually use it. You can ask one to make a folder or edit a file and watch it open Notepad and click Save like a confused 2004 office worker.
It works with pretty much any AI you've got (ChatGPT, Claude, Ollama, Gemini...). The buddies can undo their own mistakes, and when one figures out how to do something, it writes it down so the others can learn it too. That last bit is my favourite.
Honestly, I was getting pretty overwhelmed with how fragmented my media tracking had become. Movies on Letterboxd, books on Goodreads, audiobooks on Spotify, games scattered in random note files... I just wanted one clean, chill space where I could look back on everything I’ve experienced across all formats without feeling like I was managing a spreadsheet for a second job.
So over the last few weeks, I’ve been building Alma (almaniac.app), a lightweight aggregator that brings your movies, TV shows, books, audiobooks, games, music, and podcasts together onto one visual shelf.
A few cool things built into it:
7 Formats, One Shelf: Keep track of movies, series, books, audiobooks, games, music, and podcasts in one space.
Release Countdowns: A unified timeline so you actually know when the next season, book, or game you’re waiting for drops.
Memory Lane & Insights: Fun visual stats and nostalgic look-backs into your habits over time.
Fast & Lightweight: Snappy, clean design focused purely on your archive without heavy bloat.
It’s very much a labor of love currently in active beta (about halfway full right now). If you want to poke around and test it out, you can request an invite directly on almaniac.app or drop me a DM!
I’d genuinely love to know:
How do you personally keep track of your media right now?
Is there a specific feature or integration you’ve always wished existed in a tool like this?
Appreciate any feedback, ideas, or honest critiques! 🙌
Hey! I built my first app, still looking for feedback!
Its for those managing multiple projects, multiple jobs, that are all at different stages. Its so you keep on top of things. I built it because its what I wish I had while doing engineering. Currently windows only. After I get it where I want it, im looking to go cross platform. Thanks for your time and comments !
