I've been watching Nova Designs on YouTube for a while and loved how clean his code presentations look. Turns out he uses CodeSlides which is great, but it's subscription-based.

So I built OpenSlides — a free, open-source, fully offline desktop app for making animated code presentations. Think CodeSlides, but it runs natively on your machine, your data never leaves your disk, and you own everything.

I work on Pixly (AI tools for real estate media), and this started as a repeated request: agents wanted those property-line overlays on their drone videos so buyers can see exactly where a lot ends. The usual answer is After Effects, but that's a lot of heavy pro software for what's really one small repeatable job — so I built a browser tool that just does that one thing.

How it works: drop in a drone clip, draw the parcel outline once on the first frame, and GPU motion-tracking (CoTracker) keeps the boundary stuck to the ground as the drone moves. You can fix any frame with keyframes, style the line, then export.

It's free — you can try it without an account, and only sign in when you want to export the finished video.

Still early, so I'd love feedback on the tracking accuracy and the export flow.

This is a condensed version of my full write-up (will leave a link at the end).

I launched CardShows.io in the middle of March on a brand-new domain (would love feedback).

Last week it reached:

• 17,755 total page views
• 5,709 Google clicks
• 237,600 Google impressions
• Around $230/month in AdSense revenue (working on diversifying)

I built the site because I collect trading cards and couldn’t find one reliable place listing local card shows.

I built the MVP with Claude Code in a week. Building the website itself was actually pretty simple with vibe coding. Getting good data was the tough part.

I spent around 80% of my initial effort discovering shows, verifying dates, removing duplicates, standardizing locations, and finding organizers, social profiles, ticket links, and images. I now use Hermes to help repeat that process across every state each month.

The SEO strategy was straightforward:

1. Create useful pages for specific events.
2. Target the long tail first.
3. Link event pages into city, region, and state hubs.
4. Actively work on indexation.
5. Improve the hubs as they begin ranking for broader searches.

The site went from around 100 indexed pages after its first week to roughly 9,100 today.

What I'm working on now is monetization and building out more features. I'm at $230/m at the current pace of Adsense revenue, and advertisers are starting to roll in. I'm investing more time in improving the actual advertising flow to make it super easy to promote card shows.

I posted about it on X if you wanna check out a bit more detail. If you have 15 minutes, you can read the full case study here.

Happy to answer questions!

Yesterday I discovered that my first personal project has reached 10 users, and I was really pleased. You might think that 10 isn’t many, but for a project I created out of personal need, I didn’t think anyone else would use it; I never thought of this project as a commercial product, so I’m glad there are people who have found it useful.

A few days ago, I posted a demo of my tool here with a half-joking caption: "I wonder if anyone actually needs this though lol?" I was secretly worried nobody would care.

My app is just a simple, unsexy Windows desktop utility. 100% local, no cloud, no AI.

But today, after posting my demo, I saw the very first "Pro version" sale notification on my dashboard.

It's just one single sale, but knowing that someone in the world actually found value in something I built with my own hands... it's the best feeling ever.

To anyone out there building their own side projects: keep going! It's worth it.

Add your apps so people can try them

built this over a weekend and figured some of you might want it on your profile readme. it renders your contribution graph as a snake that actually plays the game: it pathfinds to your commits, avoids its own body, and grows as it eats. one python file and you add it with a single github action.

happy to take feedback or feature requests.

I’ve been building Echo, one adaptive model powered entirely by a pool of open-weight models, including GLM-5.2, Kimi K2.7, and many others.

The idea started with an experiment I couldn’t stop thinking about:

A perfect oracle that always knew how to use the models in the pool beat the state of the art on every benchmark we tested.

Echo is my attempt to make that practical.

Rather than simply routing each prompt to one model, Echo dynamically assembles and coordinates the models needed for each request, then exposes everything through one endpoint.

On our first internal task mix, Echo consistently outperformed the best individual model in its own pool and reached Fable-level results at roughly 1/3 of the total inference cost.

It already matches the state of the art on some coding benchmarks. There are still gaps on others, and improving that consistency is one of our main focuses now.

You can use it through the chat or plug its OpenAI-compatible API into OpenCode and other compatible tools.

New accounts include $10 in free inference credits.

I’d love people here to try difficult prompts and tell me where it works surprisingly well or where it still falls short.

Try Echo:

Building a news app in 2026 is so annoying because the second you say “AI + news” everyone’s brain goes:

ok cool another summary wrapper.

Fair tbh.

There are 9 million apps now that do:

paste article
summarize article
call it productivity
add gradient button
ship

That’s not what we wanted to build.

The actual thing that annoyed us was this:

You see one story on Google News.
Then the same story appears on X.
Then a YouTube video explains it badly.
Then Reddit has a better discussion but only if you already know the context.
Then 6 articles repeat the same wire copy.
Then one source has the actual update.
Then you forget why you opened your phone.

So we built CuriousCats: https://curiouscats.ai

The goal is not “AI writes news.”

The goal is more like:

show me what changed
show me why it matters
show me the story timeline
show me the sources
let me go deeper if I want
then let me leave

Like a news app that does NOT want to kidnap your morning.

But the positioning is killing me.

“AI news app” sounds trash.

“News digest” sounds old.

“Google News alternative” gets clicks but feels too small.

“Story timeline app” is accurate but maybe boring.

“News without the feed” feels closest but idk.

What would you call this?

Also roast the site if you want. I’d rather hear “this sounds generic” now than find out after wasting 6 months.

Hi everyone! 👋

A while ago, financial stress and the sheer amount of mental clutter (tracking budgets, split-payments, loans) got overwhelming. I wanted a finance app, but every single tool on the market forced me to create an account, connect a bank, or upload sensitive data to cloud servers I don't control.

To make things harder: I don't come from a traditional software engineering background, and I couldn't afford expensive cloud backend infrastructure. So, I turned that limitation into my strongest advantage. Working shifts in a factory by day, and collaborating with AI tools (like GitHub Copilot) by night, I built Nexmy.

Nexmy is a 100% offline-first personal finance app for Android.

What makes it different:

Zero Cloud / Zero Accounts: Your data never leaves your phone. Everything is locally encrypted.

BNPL & Split-Payment Tracking: Perfect for managing installment services like Klarna and PayPal.

Smarty (Beta 1.0): A lightweight, on-device AI assistant that answers your financial questions locally without internet.

Simulators & Tools: Compound interest, mortgage amortization, and clean local PDF reports.

I built this out of pure necessity to regain my own peace of mind, and we just wrapped up our Product Hunt launch. Now, I want to share it with this community.

Nexmy is completely free with no ads. I would be genuinely honored if you tried it out and gave me your raw, honest feedback or feature ideas!

Thanks for reading, and let's chat in the comments! 🚀

Hi everyone,

I recently completed my DevOps internship, where I worked with tools and technologies like Linux, Git, GitHub, Jenkins, Docker, Kubernetes, Terraform, Azure, CI/CD, Python, and Shell Scripting. During my internship, I built and deployed applications, automated deployment pipelines, and worked with cloud infrastructure.

Now I'm looking to gain more real-world experience while waiting for my full-time joining. I'm interested in:

DevOps freelance work

Small paid or unpaid projects

Open-source contributions

Startup collaborations

Infrastructure automation tasks

CI/CD pipeline setup

Docker/Kubernetes deployments

Azure cloud projects

I'm eager to learn, contribute, and solve real engineering problems. Even if you have a small project or need an extra pair of hands, I'd love to help.

If you know of any opportunities or communities where beginners can contribute to real DevOps projects, I'd really appreciate your suggestions.

Thanks in advance!

Hi everyone! I recently launched Folivy, an iOS app I built to make plant identification feel like an ongoing discovery experience rather than a one-time scan.

You can take a photo to identify a plant, save it to your personal herbarium, view your discoveries on a map, and explore nearby observations shared by other users. My goal is to help people gradually build their own plant collection and personal nature journal.

I’d really appreciate honest feedback on the idea, user experience, and which feature feels most valuable: plant identification, the discovery map, or the herbarium.

App Store:

At one in the morning, I was scrolling and thinking about how annoying currency conversion can be at times. Purchased an Apple gift card with Bitcoin and it was successful. No strange boundaries, no waiting.

so it makes me realise that, in the appropriate situation, cryptocurrency can be rather useful. Is anyone else experiencing similar sporadic moments of usefulness?

I just wanted to show that there's still place for cool animations and interactive effects in modern web

This one took me 2 days to implement, but I'm happy how it turned.

What do you think?

Not sure if I built it or Claude did, but it's done! I built this because every time I visit whatismyipaddress.com, I get bombarded with ads. You can check it out at ipgiraffe.com. Any feedback or suggestions would be greatly appreciated.

How do you handle the constant stress of side projects? I get up at 3 in the morning, work 5 hours, get ready for work, work 9 hours, some errands, and back to sleep. Can't sleep longer than 5-6 hours at most, and then I'm just to excited. Get up. Repeat.

Anyway. Can you give me some marketing tipps for https://ai-tattoos.com ?

Hello everybody,

I basically didn't sleep last night because I was thinking about so many things at once. This morning I thought to myself that I needed a system that let me put ideas away as quickly as possible, because otherwise I usually want to tear my skin apart. I have a spider-web-like thinking style which sometimes drives me insane.

Notion is too complicated and not satisfactory, the Notes app on Mac is too simple and gets crowded easily, sticky apps are cool but suck at categorising.

I needed something similar to: "you write it down on paper, then you move on and throw the paper away."

So I was like, it seems easy to do, and five hours later I've created:

noisebucket.com

For now, I just want honest feedback and opinions. I think this has potential if I manage to stay on track of being super effective and not fall into the trap of adding more and more stuff and ending up with a clone of Notion. I also want to use it for anxiety-fuelled thinking, so I can 'empty my bucket' there.

The send-away button was added because my dad wanted to send his "bucket" to his business partner, so I was like, yeah, it's not that dumb, you could also use it to send an email to yourself so you don't actually lose thoughts.

Don't hesitate to roast it if you think it sucks. :)

Best,

Noisebucket founder, I guess

Lyrics panel + turned on full haptic mode

You know how SoundCloud has those waveform comments? I went harder.

I built a player that takes any track (local or SoundCloud), transcribes it with an AI model, and maps every word to a vibration pattern. Three modes:

• Lyrics mode — feel each word as vibration

• Instrument mode — vibrations follow the mix/layout

• Full mode — lyrics + instruments layered

It's built with Flutter, wraps a custom fine-tuned Whisper transcription pipeline, that also hooked into SoundCloud through an extension I made.

Track upload & config generation takes about 3 mins (on backend service that deployed on Modal)

App source (here is .apk for download)

Hi everyone!

I got tired of reading in three places. On iPad I used Safari for long articles and Apple Books for books. On Mac I used Skim for research papers. Each tool was fine, but nothing shared the same library or the same annotation habits.

So I built a single client-side reader that can open PDFs and imported articles, with the annotations I actually use day to day.

https://pdf-reader-peach.vercel.app/

What it does:
• Read PDFs (papers, books) in the browser
• Import a PDF or blog/article from a URL into a Google Drive folder you choose
• Articles stay reflowable HTML (not a janky HTML → PDF conversion)
• Highlights, pen/mark freehand, and notes
• Annotations live next to your files in Drive, plus a local cache

Drive is optional; try the demo paper without signing in.

If you connect Google Drive, the app only uses a folder you choose for your library and annotations. Google’s consent screen will still list broad Drive read access (that’s how their scopes work); I don’t use full Drive write access. Privacy page has the details.

Google OAuth verification isn’t done yet, so you may see the unverified-app warning - Advanced → Continue if you’re comfortable. Privacy and terms are on the homepage.

I’m one person using this for papers and long reads on iPad and Mac. Feedback welcome, especially on Drive scopes, article import, and annotations.

Every time id make a change in my RN app id have to unlock my phone, go the expo app, scan the QR code, and then wait like 30 more seconds for app to load just to discover that the change that i made wasn't it

So i built Basalt, RN and Expo edit tool that lives in your IDE

Basalt, can change the color, edit text, move stuff, inspect where the element is located, or just preview your app

It is completely free and works directly inside VS Code and Cursor.

It’s currently in beta, so please commit your app to Git before testing it!

After about seven months of development, countless iterations, and several App Review rounds, my first App Store release is finally live.
Radiogram is an internet radio app for iPhone and iPad featuring:
🎵 40,000+ radio stations
🎙 Podcasts
🎼 Shazam-powered song recognition
🌍 Browse by country, language and tags
❤️ Favorites & History
🚗 Car-friendly player
📱 Native iOS experience
Ironically, writing the app wasn't the hardest part.
The biggest challenge was App Review. I had to prepare technical documentation explaining how the app uses Radio Browser and proving that it streams broadcasters' original public URLs directly through AVPlayer without proxying or redistributing any audio.
Eventually everything was approved, and today the app is finally live.
I'd really appreciate any feedback, good or bad. If you find bugs, UX issues, or have ideas for improvements, let me know.

Thanks!

I've been experimenting with different approaches to reduce my phone pickups. The breathing exercises (one sec) became muscle memory after a week — I just breathe through it and open anyway.

Time limits don't work because I just override them.

The only thing that's made me pause is when I have to actively articulate WHY I'm opening something. Like writing it down.

Has anyone found a friction method that doesn't become "rote" over time?

What's the mechanism that keeps working for you?
