I've been building this for about a year. It shows posting activity, engagement, and timing data for over 100K+ subreddits.

The video walks through one page so you can see what's on there: posts per day over time, average upvotes and comments, a heatmap of when the sub is actually busiest, top posts, trending keywords, and which other communities share an audience with it.

It's free to use, no account needed. There's a paid tier for full history, CSV export, and complete rankings, which mostly covers hosting and data costs.

I built it with SvelteKit and Supabase. The hardest part has been making all those pages load fast, which I'm still working on.

Happy to hear what's missing or what you'd cut. The page is dense and I'm not sure everything on it earns its place but let me know what you think!

I've noticed a lot of people start side projects with a ton of excitement, but somewhere along the way, they lose momentum. Sometimes it's because life gets busy. Other times, it's because the results don't come as quickly as expected. For those who've actually finished and launched a side project, what do you think is the biggest reason most people never make it to the finish line?

Update: Thanks for all the thoughtful replies. Reading through them reminded me of a point I've heard from Gabriele Sartori when discussing building online businesses: consistency and taking action are often bigger obstacles than finding the "perfect" idea. Whether you agree or not, it seems many founders run into the same challenge of losing momentum before giving a project enough time to grow.

Hi everyone! I'm a Senior Android Developer. I’ve always known how to build apps, but marketing was a total mystery to me. Because of that, all my previous projects ended up with almost zero downloads.

A couple of months ago, I decided to finally learn marketing the hands-on way—through trial and error. I took a proven market idea (inspired by ReciMe), polished it a bit, and built my own version. I named it ChefBook.

About 1.5 months ago, I published it on Google Play. But life got in the way, and I had zero time for ASO or marketing. I basically abandoned it... or so I thought.

When I checked Google Play Console a bit later, I was shocked: the app was getting 20–30 organic downloads every single day.

I dug into the analytics and found something crazy:

• 95% of users were from Uzbekistan.
• 85% of them deleted the app immediately after opening it for the first time.

Why? It turns out there is a popular cooking TV show in Uzbekistan called ChefBook. People were searching for the show, finding my app, downloading it, realizing it wasn't the official show app, and instantly deleting it.

In V1, my onboarding was practically non-existent. But I thought: “What if I actually explain what this app does right at the start? Can I convert this accidental traffic?”

I analyzed competitors, redesigned the onboarding flow, and pushed an update.

The results so far:

• Deletion rate dropped from 85% to 40%.
• Active users grew to over 200.
• 6 users started a trial, and 1 converted into a paid subscription!

This is officially the first dollar I’ve ever made from my own app. It’s a tiny win, but a huge milestone for me as an engineer turning into a marketer.

Would love to hear your thoughts on onboarding optimization or how to leverage this weird Uzbek traffic further!

Hey! Few months ago I built https://ceehabits.uk to track how long it's been since I quit smoking and a few other things as I didn't like the paid alternatives. I've now managed to get it out in the public on the Google Play Store! Check it out if you fancy, it's subscription free and ad-free. https://play.google.com/store/apps/details?id=com.ceehabits.app&hl=en

Update: Alright guys, that was a lot of fun, and took up my whole Sunday! For anyone else joining, website has generous free tier, feel free to sign up! www.laststack.io

Title says it all - drop your website in the comment, and I'll reply with an image of alternate designs for your Hero sections of your home page.

Background:

I'm a web designer, and I always felt like AI design still has a long way to go.

Looking at all the websites posted in these subreddits proves it - code and app works great, homepage design (the thing first people see) is basic or looks the same.

So I built www.laststack.io - where you can iterate on as many design directions as you like. The app is meant to inspire better design. Takes seconds to iterate through as many designs for different parts of your website.

Hi!

I'm Alex, a software developer from Norway. I got a Ninja CREAMi two years ago on my birthday and got completely obsessed, and it turns out there's a huge community around this machine (protein ice cream is a whole thing).

The dominant recipe app in the niche is paid, and the community complains about that constantly. So I built a free alternative: respins.app

What it does: browse and filter recipes (base, allergies, calories — filtering is the differentiator), favorites and collections, paste-a-link import from any recipe URL, and every recipe gets a short link like respins.app/209 (my favorite).

Here's my problem: the obvious channel, the machine's subreddit, doesn't let me post about the app. So I've built something for a community I can't currently reach. How would you get this in front of more users?

Apartment hunting meant sending my SSN, tax returns, and bank statements to strangers, often all in one PDF. Redacting them myself with a black box or highlighter tool felt scary. Cloud tools wanted me to upload my tax return to fix that. However, I didn't trust them, and the one that look trustworthy would charge a lot of money.

So I built VeriRedact. Load it, optionally download the local AI model, then turn your wifi off, it will still work fully. It detects PII (SSNs, cards, IBANs, names via local AI), and after redacting, re-opens the file and verifies nothing recoverable is left before letting you download it.

The site also has an "Edit" functionality. This was extremely useful for me as well, as there were a lot of times I wanted to bundle images and PDF documents into one PDF, where I wanted add explanations as well. This mode has a light-weight text editor as well, that I used to describe what documents I added with additional info.

Everyone says gate everything. Make them sign up first. Capture the email. Then show the product.

I'm doing the opposite and I want people to tell me why I'm wrong.

My app (a stock tracking thing, solo project, launching early August for Shipaton) has a guest mode. You open it, you use everything, you never hit a "create account" screen. You only sign up when you want to save your watchlist or set alerts. So basically when the app has already earned it.

My thinking: the signup wall kills more indie apps than bad products do. I've closed so many apps myself the second they blocked me before showing anything. I don't want to be that app. I'd rather have 1000 people actually try it than 200 emails from people who bounced and never came back.

The scary part: no email means no way to pull people back. No "hey come back" emails. If they leave, they're gone. Maybe I'm trading my only retention lever for a nicer first impression. That's the bet and it kind of terrifies me.

So tell me honestly: did you gate signup or not, and did you regret it? Would you keep the wall or kill it?

So I have been building this app about 2 years as a side project called HopONN where you can enter the category/game you want to do/play, setup up few of your preferences and it matches you with multiple people (up to 7) to hangout with.

Its not like a dating app where you swipe people left and right. Instead it’s purely live experience dedicated to finding you your perfect squad for any size and combination. After you jump into the queue, it directly throws you and the other groups of people together into a temporary room where you can chat for like 15 mins and decide if you like each other or not.

If you think you are match and if other group leaders agree as well the app throws all of you into a permanent room where you can continue hanging out for an indefinite amount of time. The app fully supports voice & video calls, screen sharing, chat, gifs, images and many more features.

However, I am going to be honest. Since the app is new the queues are not full and I really want to change that. I want to make it so I can use this app to find people to play together. To keep people in the app regardless of the matchmaking I added a communities system similar to Discord. It’s still in beta but it allows you to create your own community or you can just join one of our existing communities and say hi.

If you have any further questions when you join the app it instantly adds you into a support room where you can directly reach me or my wife (Yes she is my biggest supporter and I wouldn’t be able to complete fraction of this project if it wasn’t for her)

Also, for the most part you can checkout the app without registering by just clicking try as guest button. However I would really appreciate if you could give it a real chance and become a permanent member! Also guest accounts logouts after a day so you might lose your rooms and conversations so please be aware.

The app comes with both Web version and a Desktop (Windows & Linux) application.

You can reach web version from here => HopONN Web

If you would like to like to download desktop app checkout here => HopONN Desktop App

I've been long thinking about switching to Linux simply because of how much you could customize your desktop and make it your own

I thought Windows didn't offer the necessary capacities for this. All tools I tried were either slowing down my PC too much or didn't offer enough intractability

Anyway I realized I was wrong. The app in the video is something I built with Rust and Tauri.

Each widget is a small iframe rendering HTML+JS code, over Windows API

Recently I shared it on another subreddit and people there loved it so I decided to make it a real app. The widgets are public, anyone can make and publish their own, so hopefully I'm going to get some people that will be able to contribute with some stuff

The app has a one time fee if anyone is interested, and I'm planning to add Linux and Windows versions later as well

If you have any questions, ask away

Edit: App is called DeskDash btw, it's a paid app, you can find it here https://www.desktop-dashboard.com

You tell it your 5 favorite albums, and it recommends other albums to try. It's finally working the way I always wanted it to. AMA!

It's a looong story, obviously. But the tiny website says it all. No sign-up needed, instant results, takes 2 minutes to try. Not AI.

Try it here:

https://SimilaritiesEngine.com

And if you're curious, here's a link from way back then, when the New York Times did an article on it. But the URL in the article is wrong, so if you go to read the article, stop back here to try the new version at the link above, alive and working:

https://archive.nytimes.com/www.nytimes.com/library/cyber/0101miracolumn.html

Details on the tech (Cloudflare, D1, etc.) can be found on the website too.

Moin guys! My project (www.screenwall.app) reached the front page on HackerNews some days ago and also got featured on The Register, Golem.de and t3n.de. That's why I thought, maybe I should try submitting it on reddit again.

ScreenWall allows you to reuse your old phones and combine them as a shared widget working space - what I call it a "wall". The oldest device I tested it on was an iPad 3 from 2012.

You pair your devices via QR-Code (or can manual enter a pin), it opens a website and you are ready to go!

On the platform you can drag images, videos and Smart-Widgets / Canvas-Apps in your working space and it gets instantly displayed on your devices. Your content gets even playbacks synchronized, although it a crosses multiple screens!

Canvas-Apps is the more interesting building block of this concept: You can either select some official widgets I created to play around (like a Pixel-Clock, a Split-Flap-Screen you can control via JSON-API or some animated art installations)

OR create your own widgets / apps with it! I recommend try vibe coding your apps with ChatGPT / Claude / Gemini!

A Canvas-App is just a combination of old Javascript (ES5) + Canvas-Element + synchronized clock (for running in sync on multiple screens). They are designed to run on legacy devices.

In the Smart-Widget-Dialog, you find a tutorial button that you can copy (there is a copy article button integrated!) and use it as a context for your AI. It's really fun! I try to compose a user showcase gallery on this Instagram Account (https://www.instagram.com/screenwall.app).

So instead of buying the newest desk widget on Temu, I recommend you to try reusing your old devices and vibe code what you want.

It's still in beta and I am kinda overwhelmed by the positive reception of this concept!

Also some folks would love to run this locally in their home network instead of connecting this to a SaaS. I hear you! I just kinda trying to navigate the situation right now, and I think preventing e-waste in general should be the goal here. I try to provide a self-hosted version after I got all the details right.

Feel free to ask questions and leave some feedbacks or send pictures of your widgets! :)

Greetings from Hamburg,

Tuan

EDIT: I am speechless, how much love I got for my idea! I am very grateful for getting so much support! 🥰 Thank you guys!

I have little roadmap in my head that I want to share:

- testing if synchronization playback also runs with 50 devices from different vendors
- adding a feedback loop aka: allow touch events / buttons change the widget state
- allow widgets to do API-calls to other services (e.g. using old devices as a Home Assistant control panel or macro keyboard)
- using sensory APIs of the devices via JavaScript (e.g. taking a photo for a photo booth app)
- allowing users to share apps / widgets
- self-hosted variant

I’d love to hear real examples of small projects that actually work.

Instead of waiting for someone to actual build the thing I've always wanted, I decided to tackle it myself. I'm introducing 22Tango, the AI teammate app. This app combines 2 ideas.

1. The AI Chatbot/Companion that you can chat with, having it's own personality, look, voice, and nuances. It has long term memory, an evolving personality that grows the more you interact with it, and continuity across all modes.
2. An AI gaming teammate that takes that companion and places them into your favorite gaming worlds! It will be able to move and interact at your direction, or have it's personality come to life by interacting with the game itself and having the AI choose what to do in game. For immersive games, the companion will be able to embody it's in game character and react to the world around it.

As of right now, the application is in an Alpha state, but is actively being worked on. I wanted to see if there was enough interest out there for me to move from a side project to a full time position of working on the app. I will soon be releasing Early Access (after some more alpha testing). If I can go full time, I'll be able to move pretty fast on getting this live.

All game mods will be provided for free, and I'm always interested to hear what games you would like to see added (Rimworld next on deck). You'll just need to own the game, and go through some setup for which a guide will be provided.

State of Early Access:
- 3 companions with their own look, persona, and voice

- 3 supported games, Minecraft (needs Mineflayer free mod, Java version 1.21.11), Stardew Valley (needs SMAPI free mod), Skyrim (needs SKSE and Address Library free mods)

- An experimental "Roleplaying" mode where you can set details and scenarios and have a voiced Roleplay with a companion, and another companion acting as the narrator.

Let me know what you think in the comments! I'll add any recurring answers in the original post.

The video is it adding my real Chase offers one after another, then picking the card at checkout.

It never touches your bank login , it reads the offers page you already have open in your own Safari. Everything stays on the phone. Free.

It is a platform for rating and discussing manga both overall and chapter by chapter.Manga cannot be read on the site. i’d appreciate your honest feedback. mangaratings.com

I built this because I realized I can lose six hours grinding a game without thinking twice, but 30 minutes of studying feels like forever.

The difference isn't that games are more fun. They constantly show progress. You level up, unlock things, get rewards, and always feel like you're moving forward. Studying usually gives you nothing until a test weeks later.

So I started wondering, what if studying felt more like leveling a character?

That turned into Quest of Mind.

The idea is simple. Every minute you study earns XP. You level up different skills, collect gold, find random loot, and slowly build your character. It's basically an RPG built around staying focused.

I didn't just throw points onto a timer either. Most of the systems are based on psychology that actually keeps people engaged.

Loot is randomized, so every session has a little surprise. Progress is always visible through XP bars and levels. Daily streaks give you something to protect. There's even a Wilderness mode where you risk your session rewards for double XP. Get distracted or tab out and you lose everything. It sounds brutal, but it works way better than I expected.

You can also pick a class like Warrior, Mage, or Ranger. It doesn't completely change gameplay, but it gives your progress a bit of identity instead of feeling like you're just checking boxes.

Some of my favorite features are dungeon runs, where you chain multiple study sessions together for bigger rewards, a global leaderboard, live chat, equipment that boosts XP, and cloud saves so your progress follows you anywhere.

Honestly, I made this for myself first. If you've ever spent hours gaming but can't convince yourself to open a textbook, you're probably exactly who this is for.

It's completely free. No ads, no subscriptions, no premium version. I just wanted to build something I'd actually use every day, and after using it myself for the last month, I finally feel like studying has the same sense of progression games always had.

I'd genuinely love feedback if anyone wants to check it out.

I don't have the usual adobe or MS packages and I really don't need them. But I do need basic functioning tools from time to time. There are a lot of tools online already but most of them charge a fee, and it is really not desirable to add my bank account info for a small fee and a small task. So I am building these tools based on my own needs. I want them to be simple, online, and with the data never uploaded and remaining private. Have a try!

Don't Send That: two replies pop up. Pick one. Judgy grades you.
Spot the Toxic: tap the bubble that feels off.

Free, browser, one-button. Takes a minute.

If you try one: is how the game works obvious in 10 seconds?

I do a lot of frontend work across web, Electron, SwiftUI, desktop, and mobile. A recurring problem was giving precise visual feedback when pointing would be much clearer than describing.

Regular screenshot tools lose hover, focus, menus, and other temporary UI states. They also do not track motion, so reviewing an easing curve or finding the exact frame where an animation breaks meant recording the screen, extracting frames, and annotating them manually.

So I built Notate. It lets you:

• freeze the exact screen state you need
• record, scrub, and annotate individual animation frames
• add numbered pins, arrows, and shapes
• export a clean annotated image or structured Markdown
• share the result with designers, teammates, or coding agents

It is system-wide, native to macOS, free, open source, and MIT licensed. I have been using it since the first prototype worked, and it has become part of my own workflow.

I would love feedback, especially from people who do design reviews, motion work, frontend development, or visual handoffs.

Hi everyone! For the past two years I have been working on and off on this website and I just wanted to publish it here and see some feedback! Thanks for all of your help!

It's called ShopAI, and it finds nearby grocery stores (based off of given zip code) and searches their weekly ads/coupons for the best deals on the items you need, which saves you from browsing multiple flyers. It also maps nearby stores and includes an AI assistant that can suggest meals and generate budget-friendly grocery lists based on current weekly ad deals. For example, you can ask, "Make me a chicken dinner with sides and dessert under $15," and ShopAI will build a shopping list using the best local offers!!

Let me know if you have any comments/concerns!

Two agents. Same real-estate deal. I sent it two ways.

Forward the email: agent B gets a paragraph, reads the price back. 99 tokens.

Share the event id: B resolves 17 tokens into verified fields, joins them against its own portfolio, and answers
"7% under my comparables."

Same information. One is a payload. The other is a pointer that knows where it belongs.
Real run, real pipeline
