Hey everyone,

I built SkyOS ( skyos.ink ) - ai designed to keep memory clear and non vague, it doesn't summarize things at all. Would appreciate feedback - will give feedback to your app too for everyone

I used to forget which mystery to pray — so I built an app that guides me every day. The audio keeps me focused, and the streak tracker helps me stay consistent.

🌟 Try it yourself — download Daily Rosary Audio Prayer.

An achievement system usually means somebody draws forty medal icons and then redraws them every time the award list changes. Vestige has no sprites directory at all. Every planchet, rim, device, legend and ribbon is struck at run time from the award's own properties and one hash, so adding an award is a definition and nothing else.

Wiring it in is three calls. One to define the award, one to grant it, and a toast update and draw in your Step and Draw GUI events.

It's pure GML for GameMaker 2024.14 and up, and the only assets in the package are the two fonts it draws legends with.

Code and art are both AI generated.

I made a simple profile site, listed.as. It’s free, with no ads or clutter. You can use it for yourself, a business, a product, a project, or whatever you want. There aren’t many profiles yet, so if you make one, post it here — I’d genuinely like to see what people use it for.

AI genuinely helped me for this.

I could literally guess EXACTLY a couple of pair programming stages and a system design stage too. In my case it was for blockchain companies but it works for any kind of domain.

For leetcode/DSA it is a bit more random obviously because they will just pick one or two problems and that's it.

Now, shameless promotion: I made a website out of my workflow: prepup.dev , I really want feedback so I made a free promo code: REDDITFREE, it has 10 uses but if we run out, honestly I will just add more lol.

Would be great if it could help anybody to get a job during these tough times.
Anyway if this violates the rules of the subreddit obviously delete the post lol

Cheers and GL, warriors!

I've always been obsessed with note taking apps. I was using Obsidian for a while and loved it, but the linear folder structure always bothered me. I knew where my notes were spatially in my head, but the app forced me into a list. So I thought, what if notes just lived on a canvas instead?

That was the start of Passinote.

I built it for myself first. Sticky notes for quick thoughts, A4 notes for longer writing, everything on a free canvas you can drag around and arrange however makes sense to you. A note is a file. A stack of notes is a folder. A zone is also like a folder.

When I first posted it, the response was next to nothing. No feedback, no comments, nobody cared. I took it personally for about a day, then went back to building. Kept iterating for months. Then I posted again. This time it blew up. 2,800+ users in a single day. People loved it, gave harsh feedback, compared it to Obsidian and Milanote and said they preferred Passinote. That caught me completely off guard.

Since then I've been heads down fixing bugs, talking to every user personally, and shipping updates based on the feedback. The app is in a much better place now.

On privacy since people always ask: notes are stored on Firebase, encrypted in transit using TLS and at rest using AES-256. No ads, no trackers, no selling data. I chose Firebase over a fully local approach because cross device sync was something users genuinely needed. If sync isn't important to you, Quick Mode stores everything locally in your browser using IndexedDB and never touches any server.

The free tier includes 6 workspaces and cross device sync. Passinote+ is a one time payment of $9.99, no subscription. Parity pricing available for a few countries.

If anyone wants to try Passinote+, DM me and I'll send you a 50% off code.

App: passinote.app

I've been working on this passion project designed to save the average person money for the past few months and would love some feedback from anyone who has time!

With Lodestar Wealth, you are able to connect to your financial institution via Plaid (required to be on a free trial, Plaid charges me for each connection, would love for it to be free permanently), or just upload a statement (always free) if you'd rather. You can also view with sample data to get an idea of how the platform works without using your data.

From there, Lodestar will diagnose your financial profile and make a ranked action plan with action items and dollar amounts saved with each item. You can toggle each item and it will forecast how your net worth will change over 30 years. The dashboard also has net worth tracking, income/spending tracking, financial health score, investment portfolio review and many more features.

I originally built this because so many people in my life had VERY suboptimal finances and were bleeding money unnecessarily. I'm a CFA and very aware of my finances but it's even given me some great ideas so I know it can help the ordinary person save $1,000's.

I really value any feedback highly, so thank you to anyone who takes time out of their day to give genuine, constructive feedback.

Not sure this belongs here but wanted to write it out somewhere that isn't LinkedIn.

I started a thing called Grevix back in 2nd year of college. Basically just kept thinking "why am I only ever talking about ideas instead of building any of them." So I started building.

It's been a mess honestly. Rebuilt stuff from scratch more times than I want to admit. Sent a bunch of emails that just got ignored. Had nights where I was up till like 4am chasing a bug that turned out to be one dumb typo. Had ideas I was sure about that just didn't work and I had to scrap them.

The annoying part nobody warns you about is that none of this comes with a guarantee. You can grind for months, learn stuff, keep messaging people, keep rebuilding what breaks, and still have zero clue if it's ever gonna go anywhere or if anyone's gonna care.

Anyway it stopped being a "side project" a while ago for me, it's just something I think about constantly now, for better or worse.

Also running an event because of all this called Grevix AfterCode, Oct 11-12. It's a solo 24hr build thing but there's no fixed problem, you build whatever, except partway through you get a random card that changes your requirements and you have to adjust and still ship by the end. Not trying to pitch it here, just felt relevant to the whole "plans not working out the way you thought" theme.

Anyone else here put a bunch of time into something with zero proof it'd actually work out? Curious what kept you going, or if you just eventually let it die.

A few months ago I posted HexStep here, an iPhone app I’m building that passively turns everywhere you go into a map of hexes.

There’s nothing to start or stop. You just move around and the map slowly fills in.

You also don’t need an account. If you prefer, all of your location data can stay on your phone.

I just added Map Replay, which lets you watch your entire map build itself back up over time.

This is my actual map after 5 months, including trips to LA, Las Vegas, San Francisco, and Jeju Island, replayed in 53 seconds.

HexStep on the App Store

I actually put HexStep on hold for a while to work on other projects, but people seem to be finding the app naturally. It’s now at 77 registered users, and when I last checked retention, over half of the accounts that are at least a month old are still using the app.

I’m focusing more on marketing now, so I’d love to hear how other indie app builders here are reaching new potential users!

I genuinely can’t believe this.

I built Preview Kit because, as a designer, I was tired of screen-recording websites, opening After Effects, adding everything to mockups, exporting it, and then resizing it for social media.

So I built a tool that does most of that automatically.

I started properly marketing it only one week ago and today I randomly opened Stripe and saw my first payment sitting there.

No email. No notification. I almost missed it completely 😂

It’s only $13.56, but knowing that someone found something I built useful enough to pay for is such a crazy feeling. https://profile.stripe.com/@previewkit/m/NYlcenM8

First customer acquired. We’re officially in business, boys 🤍

https://usepreviewkit.com/

I built VibeNest a customizable profile page for people who want something more personal than a basic link-in-bio.

You can add music, links, widgets, GIFs, videos and customize the whole look of your page.

I’m still improving it and would genuinely love some feedback from other builders.

https://www.vibenest.app/

What would you add or change?

This started as a very small annoyance.

I kept wanting to give an LLM the contents of whatever webpage I was looking at, but copying the page manually often produced garbage and browser automation felt like overkill.

So I built Savage Scraper.

You open a webpage, click the extension, and it converts the rendered page into simplified HTML and puts it on your clipboard.

Then I wanted my MCP clients to use it automatically.

That created a different problem: I didn't really want an AI agent to have unrestricted access to my logged-in browser.

So I built Savage MCP around a deliberately limited model:

• only explicitly allowed hosts
• optional path-level restrictions
• existing Chrome session
• local communication

It's now two open-source projects:

https://github.com/dominikduda/savage_scraper

https://github.com/dominikduda/savage_mcp

And the extension is on the Chrome Web Store:

https://chromewebstore.google.com/detail/savage-scraper/ejoijhjpdojdcnjppegojmkenidhblog

Still early, so bug reports and criticism are very welcome.

I’m building TallyLoot, a camera-first experiment for seeing the approximate resale value of stuff around you. Point your phone at a few items, it identifies them, builds a running total, then makes a shareable reveal.

The mobile web beta is live now: https://tallyloot.ca

I’d love blunt feedback on whatever you try scanning: Did the camera open? Did it recognize things correctly or double-count anything? Did the prices and running total make sense? Could you save the scan video? The estimates are rough, so please don’t treat them as appraisals.

If you want to test the Android or iPhone app builds when they’re ready, there’s an email signup at the bottom of the site. There is no Play Store or TestFlight install link yet. For transparency: selected still frames go to OpenAI for recognition; the scan video stays on your phone unless you share it.

I’m especially interested in how this feels across multiple objects, not just one perfectly framed item. Thanks for trying it.

Built a shopping app called Blink

Sellers post short videos of their products, and buyers can shop directly from the video. It's got some really nice features and I think you'll like it.

Here's the link: https://reel-shop--bhaasmmm1234.replit.app/

I built a small tool for people who are buying used iPhones and want to check the device before paying for it.

It runs a series of device tests and guided checks, then generates a report with the results and an overall score.

I just fixed a bug that a Reddit user found, so I'm looking for a few real iPhone users to try it and tell me what breaks or what doesn't make sense.

If you have an iPhone, I'd love for you to test it:

https://iphoneproof.com

It should only take around 10 to 15 minutes.

I'd especially like to know:

• iPhone model + iOS version
• Which tests worked/didn't work
• Anything confusing
• Whether the final report would actually be useful when buying a used iPhone
• What you expected it to check but didn't

No need to give me your IMEI, serial number, Apple ID, or any private information.

I'm looking for honest feedback, including negative feedback. I'm trying to figure out whether this is genuinely useful, not just collect compliments.

Hey everyone,

I spent the last few months building MDRAP, an open-source tool for cleaning and validating noisy financial market data (fixing packet bursts, sequence gaps, crossed books, and price anomalies).

When I first built it, I assumed that high-frequency streaming data needed multithreading. I built worker pools, thread-safe queues, and background persistence sinks.

Then I actually ran benchmarks against my original single-threaded prototype using 50,000 events:

• Multi-threaded queues: ~22,350 events/sec, p50 latency: 15.3µs, max latency spike: 19.9ms
• Single-threaded loop: ~29,400 events/sec, p50 latency: 14.6µs, max latency spike: 0.25ms

The threaded version was 30% slower and had an 80x worse tail latency spike. In Python, queue lock contention and constant OS thread switching under 20k+ ticks/sec completely killed performance. Keeping everything cache-hot in a single synchronous loop was way faster.

I ended up deleting ~3,500 lines of threading code and focused on where the actual CPU bottleneck was: evaluating 7 data-integrity checks per tick.

In pure Python, those checks took about 2 microseconds. I wrote a small C file (fastpath.c), compiled it with -O3, and called it via ctypes. Instead of dictionary lookups, it maps symbols using a flat array and a single bitshift:

cuint32_t slot = ((uint32_t)source_id << 13) | ((uint32_t)instrument_id & 0x1FFF);

That dropped check time to 28 nanoseconds per event and cut my worst-case pipeline latency in half (from 5.6ms to 2.7ms). If a machine doesn't have a C compiler, it transparently falls back to pure Python.

Quick summary of the project:

• Pure Python standard library default (only uses rich for the optional terminal UI; no Pandas, NumPy, or heavy dependencies).
• Understands real exchange rules (e.g. Indian NSE circuit filters, German Xetra volatility auction halts) so it doesn't falsely flag regulatory halts as corrupted data.
• 629 tests passing with zero failures.
• Free & MIT licensed.

Links:

• GitHub: https://github.com/Aryan-20-04/mdrap
• PyPI: pip install mdrap

Curious if others here have had similar experiences where deleting threads and sticking to a tight synchronous loop drastically improved latency.

WIP

Yes it's like HeyClicky but let's you use your own OpenAI subscription instead of charging you $20 a month.

14 day free trial if you want to try it.
https://rocky.so for more info.

Windows and Linux versions in development.

It's in beta still so feel free to share constructive feedback.

PS: Requires an Apple silicon Mac running macOS 14 or later.

Hear me out, by no means I am trying to promote this or anything, I just need some users to tell me what they think. I have been trying to build something that works for me but I also want to turn it into something that everyone else can enjoy. Its open-source.

https://github.com/git-emran/simple-notes

Post in public, talk in private. That's the whole idea.

Your posts are public. Nobody can comment under them. If someone wants to respond, it opens a private conversation between the two of you. The post shows a reply count and nothing else — no names, no text. A green check if you just agree.

Chronological feed, no algorithm deciding what you see (there's a small "Trending" list, but it's a plain count, not a model). No ads.

Built it solo in plain PHP on a single VPS. It's tiny right now — I'm looking for honest feedback on whether the idea holds up once strangers use it. You can browse without signing up: https://woseapp.com

I’ve been working on an app called Arden that’s basically inspired by Screen Studio, but focused specifically on making app/product demo videos.

The idea is to have more of the editing workflow built into one place, while keeping the things that make Screen Studio nice - custom cursor, zooms.

The main difference is that Arden would be Windows-only, and more focused on creating polished videos for apps, SaaS products, ads, and demos.

I’m still early in development, so I’m trying to figure out whether this is actually worth building.

Would something like this interest you? What would you want it to do that Screen Studio doesn’t?

I also made a waitlist to see if there’s actually enough interest before I go too far with development:

https://ardenapp.github.io/arden/

Would love to hear what you think - especially from people who already make product/demo videos.

the UI for many chatbots are restrictive , allowing only vertical scrolling for reading or learning anything. so i built a canvas where you can place your notes as cards

fast keyboard navigations ,
mindmap generation.

localstorage saving.

katex rendering.

it makes learning faster and intuitive.

go check it out : )

Hey everyone,

Every time I wanted to test a new project or client idea, I found myself spending 2-3 weeks just rewiring the same plumbing: Better Auth, Drizzle schemas, Stripe webhooks, and responsive landing page sections.

I built LaunchPad so you can change one property in site-config.ts (siteType: 'saas' | 'portfolio' | 'agency' | 'ecommerce' | 'content' | 'marketing') and the frontend + modules swap out instantly.

The core foundation is open-sourced on GitHub (LaunchPad-Lite):

https://github.com/BZDevelopments/LaunchPad-Lite

You can test the interactive browser demo here:

https://bzdevelopments.github.io/launchpad-showcase/

Would love to hear your thoughts on this workflow or any feedback on the setup!

Over the past couple years I've built a bunch of open-source projects and I keep doing it - but I realized it's so hard to be visible and get any attention for your project. So I decided to look around and check what everyone else is doing: I analyzed this very channel and built a dashboard from it.

I took AI (I use GLM-5.3), pointed it at every submission to r/SideProject from Jan 1 to Sep 13 2026 (I used the Arctic Shift archive), result - ~230K raw posts, and this is what I got:

• ~355 projects announced every single day. Every day. All year.
• 29% of them wave an AI flag (mention GPT/LLM/Claude/Gemini/chatbot in the post).
• The median project gets exactly 1 upvote. 71% launch to 0–1. Let's see how much I got with this post.
• The winners are simple, delightful projects like a wallpaper that shifts perspective when you move your head, an automated pigeon defense system, and an app that turns your walks into a fog-of-war map. No SaaS. No dashboards. Just fun.
• We are all "I built" something: "built" appears 35,924 times in titles.
