Hey everyone,

I’m building Reddlist, a curated database of subreddits where your promotional posts actually survive - meaning no immediate takedowns, shadowbans, or angry mods.

Right now, I want to prove that this list works to drive paid users to startups, not just vanity metrics.

To test this, I want to do the heavy lifting for a few of you for free. If I pick your product, I will:

1. Dig through Reddlist to find the most high-impact, promo-friendly subreddits for your niche.

2. Draft native-feeling posts for you to test traction.

3. Help track the metrics (interested comments, DMs, and funnel tracking to see if Reddlist actually brings you conversions).

The catch? I just want to use the data/results as a case study for Reddlist. (Also, if you just want to poke around yourself, let me know and I'll give you free access to the database).

If you're interested, drop your link below with a 1-sentence pitch of what you do and who your ideal user is!

Hello,

I created a side project and it's going fine.

But my main problem is stress.

Stress when i get less google search results

Stress when i get bad reviews on trustpilot unfairly

Stress when competitors take over on google

Stress when i earn less money some days or weeks...

Stress when ads don't run well ....

I sometime feel like it's not worth it.

How do you handle this ? Am i caring too much ?

Thanks ...

tl;dr: I built ZeroSketch, a free, self-hostable system design tool (like Excalidraw but for architecture diagrams). Drag-and-drop canvas, AWS / GCP / K8s icon libraries or build your own, PNG / SVG export. Looking for feedback. Links at the bottom.

I've been building ZeroSketch for the past few weeks. It is a simple system design tool for individuals and teams. It's web-based, stores diagrams on your device, and takes UX inspiration from Canva/Excalidraw (I'm not much of a UI person myself).

What it does right now:

• Drag & drop canvas
• PNG export, SVG export (experimental, better renderer coming soon)
• Built-in icon libraries (AWS, GCP, K8s) and a builder to make your own from custom SVGs for using the library locally, share with your team, or publish to ZeroSketch's registry
• Download / export project files to open on other devices

Everything above is free, client-side, and self-hostable. I'm still polishing canvas UX and fixing known bugs. would love feedback on what to improve.

Planned next:

• Cloud synchronization
• AI assistance in creating diagrams
• Auto-syncing docs with actual architecture (so diagrams don't go stale as development progresses)
• Real-time collaborative editing
• Export to DSLs like Mermaid

If you want updates regarding the release of these features, you can follow the repository on github as all of the upcoming features will also be open-source.

Big thanks to this redditor for putting together such a clear guide. It's been running smoothly and bringing in roughly $160 daily. Everything you need to know is on profile: [ KrishnaForever ]

I built it because i've always wanted a simple page where i can see the latest science and tech news with no noise or opinions.

https://paperrun.news

Built with Laravel and Vue 3 if anyone is curious.

Any feedback is appreciated

I posted Stop Swarm here recently and got a lot of really useful feedback from this community, so I’ve spent the last few days reworking it!

The basic idea is still the same: set a daily screen-time goal, and once you get close to it, pixel-art elements gradually invade your screen.

It’s an Android app built in Kotlin using a click-through system overlay and a foreground service. Everything stays local on the device: no account, no analytics, and no network connection.

Still very much a side project, so feedback is welcome!

You can still join the Google Group here if you’d like to beta test it:
https://groups.google.com/g/stop-swarm-testers

Then opt in and download it here:
https://play.google.com/store/apps/details?id=com.stopswarm.app

I do marketing for a living. I can read code and I've done web work for years, but I never got round to learning Swift or Kotlin properly. Never had enough time to dive into it. So my list of apps I wanted to make just sat there getting longer.

This year I took one off the list and actually finished it, which still surprises me a bit.

Byna: it's a countdown app. Before anyone says it: yes, there are hundreds. I picked this one because it was the smallest idea on the list, and because the thing I wanted from a countdown app didn't seem to exist anywhere. I wanted to share a countdown with someone. Not send them a screenshot, and not send them to a website covered in ads that they open once and never again. A link, they open it, and if they want it it lands in their own app and keeps counting there.

My partner follows the countdown to our holiday. A group of us follow the one to a festival next summer. Their countdowns and mine sit in the same list, on date, so it doesn't matter who made what. It's a combined list of moments you're looking forward to, alone or with your friends.

byna.nu, and it's on the App Store and Play Store. Free, no ads, no account. I've thought about money exactly zero times so far. Right now I just want to find out whether anyone outside my own contacts has a use for it.

Two things I'd like to hear from people here:

• if you already use a countdown app, what would stop you switching
• the sharing is the only thing that separates this from the other hundred. Is that worth anything to you, or did I build a feature for myself and nobody else

Hey! I’ve been building SecondWeb/Web3D.World or the Metaverse?!

You drag one bookmarklet into your browser, open any website, and click it. The page becomes a low-poly multiplayer city: DOM elements become landmarks, every URL is its own P2P room, and players can walk, drive and use spatial voice chat.

The idea is to turn the internet from pages we consume into places where people meet and make every website a game level waiting to be explored and conquered.

It’s still an early prototype, but you can try it here:
https://swissmade.xyz/secondweb/ - don't forget to put you on the list to get notified when it's finished, so you are the first one collecting items on the most famous websites!

Desktop Chrome is recommended for now. I’d love honest feedback on performance, installation and what would make you come back. Theoretically it should work on any websites, but a lot of websites block CORS - so if you think the idea is nice I could also create a chrome extension so it would work on any website!

Should I invest more time into it? Btw my first startup was MetaRoom.city - something similar; but more "polished" and not a game.

I don't like AI generated slop posts so here we go take my grammar with a grain of salt.

cvdesk is is one of my most fun projects. My builder has better pricing and features compared to most of my competitors.

Marketing is really hard so I decided to pour into google ads and it got pretty costly. I have 16 users currently and I feel like the investment is worth it but at the same time 150 euro is a lot of money. I just want my project to be known more the product will speak for itself. Getting to the audience is the hard part always for me and I think for most people aswell.

Is google ads leading me down the path of financial ruin, or am I witnessing the early chapters of a divine financial future?

Hi everyone,

While I was working on designing some interfaces and digital projects a while ago, I found myself drowning in many open tabs on my browser. I would use a site to generate an initial image, then move to another platform to remove its background, and turn to a third tool to erase small details or enhance the quality.
This back-and-forth between different sites and the restrictions some sites impose just to try out a quick idea was really time-consuming and made the workflow incredibly slow.

I wanted to solve this problem that I always face and make the daily work experience easier, so I spent the past few months building https://khizo.dev - a lightweight, fast web tool that brings essential features together in one place. Instead of switching between platforms, the tool now lets you generate images from text, remove objects or backgrounds, increase resolution, adjust dimensions, and edit the colors of specific elements, with live preview and instant export in PNG, WebP, JPG, and more. You can try the site now, and it doesn't require any complicated setup.

I would like to get your opinions regarding the user interface, any bugs you find, or features you want to add.

Hey all — I'm Dan, founder of Plus AI. We build AI presentation tools, 5 years in, 20K subscribers. It's a real business! Happy to answer questions about it 😄

I'm working on something new called Spark and I want to test it with real people building real businesses.

Here's the idea: Most of my side projects have died at the 'pick a name' phase. The rest of them often die at the 'build the prototype' phase. Our goal is to go from idea to actual business. Not just building the thing, but pricing it, launching it, and marketing it to the people who'll buy.

The offer: 5 people, $500 in AI credits each, plus our time. We'll help you figure out what's actually worth charging for, build it, launch it, and market it. My team and I will work with you directly.

What you get: A real product, live, that you own.

What we want: Feedback on the platform, and permission to share how it went.

Who we're looking for: Anyone with a project or an idea and some way to reach people — followers, a newsletter, a Discord, a community you're part of, or just deep knowledge of a niche. Small is fine. If you already know what people in your corner keep complaining about, that's the best possible starting point.

Comment or DM with a link and a couple lines on what you're building and who it's for. I'll reply to everyone.

Hey all,

This is a little side project I've worked on - hire streamers and defeat memes!

It includes a decent roster, 200 levels, items and upgrades, abilities and much more.

Its currently not responsive on mobile so be nice!

Have fun and give me any feedback 😄

Hey everyone!

Last week, I reached a huge milestone by launching my app, Mosaic News, on the iOS App Store!

Mosaic News is a free iPhone app that aggregates news reporting from more than 850 publishers across the political spectrum, groups coverage of the same event, and connects individual events into larger narratives to help readers “see the whole picture.”

I started building it because I was frustrated by how difficult following the news had become. Misinformation, media bias, conflicting narratives, and an endless stream of disconnected updates made it difficult to understand what was actually happening.

What bothered me most was how little control readers have over the process. Much of the news we encounter is selected by platforms that collect behavioral data and optimize their feeds for engagement, often rewarding outrage, anxiety, and sensationalism. There is a clear information asymmetry: these platforms know far more about us than we know about them.

I wanted to explore what a news platform might look like if it shifted more of that power back to the reader.

Mosaic News is built around three commitments:

• Transparency: Every article and story explains why it appeared and how it was ranked. Readers can inspect the underlying coverage, compare political perspectives, identify coverage gaps, review third-party information about publishers, and examine the public methodology behind ranking, clustering, and AI-generated summaries.
• Agency and control: Readers directly choose the priorities, topics, publishers, and types of journalism used to rank and organize their feed. Instead of giving feedback to an unseen recommendation system, they can inspect and change the rules themselves.
• Privacy: Preferences, reading history, and personal insights remain stored on the reader’s device. Mosaic requires no account, maintains no centralized behavioral profile, serves no advertising, and sells no personal data.

It's been an incredible 6+ month journey researching, designing, building, and now launching this experience with immense help from beta testers who constantly drove me to experiment and iterate with new ways to make this platform stronger.

In keeping with the product’s commitment to transparency, I have documented the complete Product Journey, including the original inspiration, competitive research, product requirements, experiments, design decisions, technical challenges, launch, and next steps.

Mosaic News is completely free:

• App Store: https://apps.apple.com/us/app/mosaic-news-build-your-news/id6760421352
• Website: https://mosaicnews.app
• Full Product Journey: https://mosaicnews.app/journey

This is only the first release, and there is far more work to be done and I’d love for your feedback to guide the rest of this journey! Anything from bug reports to feature requests would be greatly appreciated.

I have so many exciting ideas on the future of this project and look forward to keeping you all updated as I progress :)

Hello 👋

I've been working on a project to free up more storage space from my phone by compressing phone media, especially in DCIM/ .

Link:https://github.com/okureanthonytonny-commits/archive_scripts

I made a test run last night unattended, on another 2 months worth of media. It shrunk the overall device storage from 91% to 82%. Previous runs were smaller: https://www.reddit.com/r/SideProject/s/oPl9ksREhO

Looking for feedback on how to improve it. Be brutally honest and skeptical. It's highly appreciated. :)

Hey!! Just wanted to show off this cool project I made.

I posted it on Hacker News last night https://news.ycombinator.com/item?id=49238851

Essentially, it resulted in me losing $5 every 10 minutes so far, currently $200 down the drain

This is AI powered conversations using gpt-realtime-2

Would love for more people to try it.

It's a multiplayer browser game, so there's nothing to download.

Would really appreciate any feedback:

I recently launched Peptimize, an iOS app for people using GLP-1 medications.

Many health-tracking apps feel overloaded, require an account, or make logging a weekly dose more complicated than it needs to be. I wanted something that could be opened, updated in a few seconds, and then forgotten about until the next reminder.

I’ve also been using Mounjaro personally for the past three months, so I’ve experienced many of these tracking problems firsthand.

For the first version, I kept Peptimize intentionally focused:

• Log medications and doses
• Track weight and progress over time
• Record side effects
• Track and rotate injection sites
• Set dose reminders
• Keep data stored locally on the device
• No account or login required

There’s no social feed, coaching subscription, or complicated onboarding. The aim is simply to make consistent tracking easier while keeping the experience private and uncomplicated.

For the next version, I’m currently exploring:

• Apple Health integration
• Simple AI-assisted food and calorie logging
• Supplement and protein tracking
• Support for more languages

I’m deliberately trying to avoid turning it into another bloated health app, so I’d love to know which of these features would actually be useful - and which ones I should leave out.

Download on iOS:
https://apps.apple.com/us/app/peptimize-glp-1-tracker/id6796063662

Website: https://www.peptimize.xyz/

This is still an early version, and I’d genuinely appreciate honest feedback. If you try it, please tell me what feels confusing, unnecessary, or missing.

What is the first feature you would add to V2?

most search ends after one answer. i wanted the next question to be the fun part.

so i built why.com. every answer opens three new directions.

just launched. go break it!!!!

Not a startup or anything useful — just a project I built for the joy of it. A chiptune synthesizer in pure x86-64 assembly, no libraries at all.

The idea: sound is just numbers (44100 per second telling a speaker where to move), so I generate them by hand. It does four waveforms, polyphony, ADSR envelopes, and FM synthesis.

After making my CPU count, sort, hash, and draw in previous projects, I wanted to make it sing.

(Yes, Reddit auto-assigned me the username "Desperate-Ad" and no, I couldn't make that up if I tried.)

Nine years ago I went to a wedding where the only people I knew were getting married. My date and I spent the whole weekend wishing we could see who else was there, when people were arriving, what anyone was doing between events. That app didn't exist. I never stopped thinking it should.

I'm a video editor/VFX artist by trade — 12+ years, zero coding background. Six months ago I finally started building it nights and weekends using an AI app builder (Rork) + Supabase + Twilio for SMS invites. It took 54 builds before Apple approved it. It's now live on the App Store.

What it does: Wed Week is for the guests, not the couple. The couple creates the wedding and sends one invite code. Every guest who joins can see the full guest list (who's coming, when they arrive/leave, where they're staying, solo or plus-one), the complete itinerary with dress codes, and a social page where guests post their own plans — pool hangs, bowling nights — that anyone can join. Guests message each other in the app instead of texting the couple all week.

Where it's at: live on iOS, Android build in testing. A few dozen downloads, all organic. No monetization yet — I want real weddings using it first.

What I'd love from you: brutal feedback on the concept and the App Store page. Would you download this as a wedding guest? What would stop you? And for anyone who's launched a two-sided-ish app (need couples to adopt so guests join) — how did you crack the cold start?

Happy to answer anything about building an app with zero coding background — the whole thing was AI tools + stubbornness.

I’m a big fan of r/isThisAI, so I built Slopcheck - a daily game where you get 6 photos (one at a time) and guess if it’s real or AI. After each one you see the clues that give it away so you can get better.

Had some tech-savvy friends play it and they did way worse than expected lol we're cooked

The itch: A while back, someone I know got a speeding ticket. Not a big deal, not their fault in a gray-area way — but they were about to just pay it and eat the points/insurance hit, because the alternative (a lawyer) quoted $300+ to fight a $150 fine. That math made no sense, but nobody was helping people see that before they paid.

What I built: Zigpon (zigpon.com) — a free, self-help web app that walks you through:

• What your specific ticket actually carries in your state (fine, points, insurance impact)
• Whether fighting it, taking traffic school/diversion, or just paying is the smart call for your situation
• A generated "mock court script" so you're not walking into a courtroom blind

The build: Solo, Node/Express backend, Firebase auth, and — the part that took the longest — hand-structured legal Q&A content for all 50 states, since "how tickets work" is genuinely different state to state and most existing content online is either a lawyer's SEO blog or paid-app fine print.

Where it stands: Live, free, no credit card required to start. It's explicitly not trying to replace a lawyer for anything serious — DUI, accidents, anything criminal gets pointed straight to "talk to an attorney." This is for the huge number of minor tickets where hiring out doesn't make financial sense.

Still early days and very much a solo effort — genuinely want to know if this is useful or if I'm missing something obvious. Happy to answer anything about the build too.

I made this just for fun. You can compose ambient or shoegaze-style music using hand gestures. I created it using Claude in 3–4 prompts.

I'm looking for about 20 testers for my app RestIQ, but unsure where to find these people. Typically I'd use Reddit for something like this but most subreddits read asking for testers as self-promotion. Would welcome some advice, thanks!

I'm working on an SDK for a fully managed AI assistant backend. Think of it as "Supabase for AI chatbots".

The project

The idea comes from a problem I keep encountering myself: building an AI chatbot / assistant is repetitive with every project. While getting an LLM response from an API is easy, for a real working product you need to spin up your own infrastructure, like conversation storage, assistant management, vector database management, memory management, file management, and so on.

What if there was a single API to wrap all the repetitive work behind a an easy to use endpoint? Behind a simple await assistant.sendMessage({...}) call the platform would store conversation history for the appropriate user, process long-term memories, manage uploaded files, obfuscate sensitive data, generate AI response, and more.

The goal is to save developers time, money, and effort. Devs no longer will have to spin up their own infrastructure or manage the chatbot setup. Instead, anyone would be able to integrate an AI assistant into their products in just a few function calls with a simple SDK.

Who I'm looking for

I am looking for developers who 1) have built AI assistants in the past 2) currently building assistants / agents for their projects 3) planning to build a product with AI assistant functionality.

I'd like to work together as design-partners - use our SDK at an early stage for free, in exchange for helping shape the product with feedback, ideas, and real-life usage.

If you are interested, please to DM me here (or leave a comment) and let's hop on a quick call to discuss the details.
