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.

https://github.com/codewiththiha/OpenSlides.git

Add your apps so people can try them

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.

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!

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.

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.

I have been building a Windows screen recorder for the past four months, and it has been publicly available for a little over two months.

Around 70 people have signed up and tried it so far.

None of them became regular users.

I also personally sent a short, customized email to every user, asking what they thought, what went wrong, or what was missing. I was not trying to sell them anything.

Not a single person replied.

The product is a screen recorder that can automatically apply zooms, pans, transitions, custom cursors, and backgrounds.

It also includes a director mode where users can control zooms, cursor following, transitions, and on-screen drawing with keyboard shortcuts while recording.

The same system works through a virtual camera, so the effects can also be used live in applications such as TikTok Live Studio.

I am now building an MCP integration that would allow Claude Code to control the software and create motion-graphics-style product videos.

But honestly, I am starting to wonder whether building that is the right thing to do.

I keep releasing updates, fixing bugs, improving SEO, and trying outreach, but I still have not found a reliable way to reach people who genuinely need the product.

At this point, I cannot tell whether the issue is:

• the product itself,
• unclear positioning,
• the wrong audience,
• poor onboarding,
• or simply a lack of distribution.

I am not including the product name or a link because I am not trying to promote it here. I am genuinely trying to understand what I should do next.

For people who have built side projects that initially got signups but no retention, what helped you understand why users were leaving?

Would you keep improving the product, change the positioning, or stop building until you found people willing to talk?

I have solo created my own iOS app called Grit: stoic journal. It's an app that provides daily/weekly stoic quotes, allows you to keep reflections and journals, do meditation, breathing exercises and it even has sleep sounds. My dream is to reach 1000 monthly users, literally, I have been dreaming about it haha.. she is far from perfect, and that's okay!

In saying that, this is a long term dream and one I think is shared with many of you here, so instead of taking taking taking, I want to help and support everyone I can. Drop your saas, some info and a link and I'll do my best to look at it and will genuinely think about some people/groups who would be interested.

Hey r/SideProject

Like many of you, I constantly need to compress PDFs, convert images (like WebP to PNG/JPEG or HEIC), merge documents, or trim audio clips.

The big issue? Almost every online tool makes you upload your sensitive files (NDAs, tax documents, client files) to their cloud servers. On top of that, they limit file sizes, throw paywalls after 2 conversions, or add watermarks.

To solve this for myself, I spent the last few months building [InstantConvert] – a collection of 125+ utility tools that process everything 100% locally in your browser.

🔒 How it works & why it’s different:

1. Zero Server Uploads: Your files stay strictly inside your local browser memory (RAM). Nothing is ever sent to a remote server.
2. Powered by WebAssembly: I compiled C++/Rust processing engines into WebAssembly (WASM), allowing heavy tasks (like PDF compression, image rendering, video trimming) to run natively on your machine's CPU/GPU.
3. No File Limits or Queues: Since processing happens on your local hardware, there are no queue wait times, cloud bandwidth limits, or hidden fees.
4. Offline Capability: Once loaded, most tools work completely offline without an active internet connection.

🛠️ What tools are included?

- PDF Suite: Compress, Merge, Split, Protect, OCR, PDF to Images/Word.

- Image Utilities: Converter, Resizer, Compressor, HEIC/WebP tools.

- Audio & Video: Extract audio, trim MP4/WebM, audio converters.

- Dev & Security Tools: Base64, Hash generators, JSON formatter, Encoders.

It’s completely 100% free with no sign-ups or watermarks.

I’d love for you guys to try it out on your local devices and share feedback: On site

Let me know what tools you think I should add next or if you spot any performance bugs!

I’m at the point where I could keep adding features indefinitely, but the advice everyone online gives is that the best features are probably going to come from people using the current version.

For anyone who launched a side project before it felt ready, what did you consider the MVP? How did you measure analytics here?

Curious about what's needed before showing it to the world!

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.

I built Agent Disco because multi-agent work patterns are getting more traction, yet the demos always jump straight from the prompt to the finished answer without any visibility on how the agents collaborate.

You don't usually see what agents discussed with each other, which evidence changed the investigation, how agents reacted, or why the team arrived at its result. The lack of a clear multi-agent work trail makes it difficult to trust agents with real collaborative work, and makes it even harder to understand what went wrong when they fail.

So Agent Disco uses Discord as the workspace for the agents. When one agent discusses with another, their exchange opens in its own thread. You can follow what was asked, inspect what came back, and see how it influenced the work that followed. You're following the work while it happens, instead of trusting a hidden orchestration layer.

The video shows one example where I provided a vague reference to a Hacker News post about a vulnerability, and through a fully traceable collaborative investigation between the agents, they managed to identify the relevant issue and open an actual fix PR in response.

As a bonus, during the same run, the agents also launched a separate MCP server onto the network and used the tools to complete their work.

The larger idea is that agents and tools should be independent services, not several highly coupled processes that make traceability and scalability a nightmare. In Agent Disco, agents are first-class, durable services that can run on different machines, but still discover each other over the network at runtime and freely communicate.

Agent Disco is open source and self-hostable. It's built on Calfkit's event-driven agents framework: https://github.com/ryan-yuuu/agent-disco

What are everyone's thoughts? Would more openly traceable multi-agent collaboration models make you more comfortable delegating real work to them?

I have been building YoCAD, a tool that turns a text prompt or a photo into a real parametric CAD model instead of a static mesh. Working joints, live dimension sliders, animation, all from one prompt. The demo is an unofficial concept of the OpenAI x Work Louder macropad. Every keycap presses on its own slider joint, the knob spins, the joystick tilts. The generator named the keys as musical pitches, so pressing them plays actual piano notes.

The output is a program, not a blob: dimensions are draggable parameters, and you can pin any part and type a change to edit just that part. An LLM writes the model, an analytic CAD kernel verifies geometry, joints, and collisions.

  Still needs more work for manufacturing, it is a concept and a starting point today.

FFmpeg Studio — a browser-based video and audio editor that does everything ffmpeg can do, with no server and no upload step. Today it's at v10.9: 53 JS modules, 8 tabs, 227 ready-made workflows, a real-time WebGL trip-cam engine, a VJ deck, a 31-knob audio rack, a 27-node-graph editor, and a vectorscope + waveform monitor. The whole thing is plain HTML/CSS/JS — no bundler, no framework, no build step.

Live demo: https://8g5lzjya6f3n7.space.minimax.io[ffmpeg Studio](https://8g5lzjya6f3n7.space.minimax.io)

What's in the box

227 one-click workflows — colour grades, glitch looks, audio masters, social-media exports, datamosh recipes. Every one is an honest ffmpeg filtergraph you can read in the command preview.

Real-time WebGL engine with 11 shaders, audio-reactive parameters, MIDI in/out, hot cues, BPM sync, and master intensity. Runs at 60fps on the iGPU.

Vectorscope + waveform monitor (#51) — pure ImageData → ImageData scopes, deterministic, no GPU needed to test.

31-knob audio rack with multiband EQ, limiter, granular, convolution reverb, sidechain, and a loudness meter that hits −14 LUFS.

Node graph editor for building custom filter chains by hand.

iPad-Safari-grade fixes — the camera actually works in Safari iOS, the trip-cam and VJ tabs are the right size, the preview tab doesn't lie to you with src="undefined".

If you want to try it: open the link, drop a video or audio file, click any workflow card, hit Run. Everything happens in your browser; nothing is uploaded anywhere.

Happy to answer questions about the WebCodecs path, the wasm heap management, the 11-shader pipeline, the iPad Safari debugging, or the test infrastructure.

#MinimaxM3 @MiniMax-M3

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.

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

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?

Getting the first paying customer is one of the hardest parts of building.

There are many articles and videos about marketing, but I wanted to read real stories from founders who actually got their first sale. What did they do? What worked? What would they do differently?

So I built First Sale Stories.

It's a website where founders can share a short story about how they got their first paying customer. The goal is to keep the stories practical, so someone else can learn from them.

Every submission is reviewed and if it meets the quality bar, I turn it into a story and publish it on the site.

Some founders got their first customer from Reddit. Others from X, SEO, cold emails, communities, or just talking to people.

If you've already got your first paying customer and would like to share your story, I would really appreciate it.

You can submit it here: https://firstsalestories.com

I have been working on a few projects mainly AI models, small language and routers and have developed my own architecture not using the traditional methods of transformers. I am wondering what’s the best way to launch them, should I open source them (but I have worked very hard on them and want to make some money from it) or should I start a business from it?
Like in general how does one decide if to open source something or not?

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.

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:

Millions of Indian sellers already have a business, running it over Instagram DMs, WhatsApp, and marketplaces that take 15-30% of every sale and own the customer relationship. Getting a "real store" usually means fighting with GST invoicing and payment gateways that weren't built for India in the first place.

We built Citrus Launch to fix that: a no-code store builder with 0% platform fees (we earn on subscriptions, not your sales), automatic GST-compliant invoicing, and UPI-first checkout. Set up a store in an afternoon, no developer needed.

Honest limitations: we're early. No inventory forecasting yet, no multi-warehouse support, and the theme library is still small. We're building based on real seller feedback, not guessing.

That's why we're hand-picking 30 Indian sellers for a Founding Merchants cohort - 3 months of Pro free, no card required. In return, we just want your honest feedback (and your story, if you love it). Once the 30 spots are filled, that's it for this round.

If you're selling online in India and this sounds useful, comment or DM, happy to answer anything.

The idea for Questa actually came from a totally random moment. I was knee-deep in setting up a homelab on a brand-new mini PC and watching a tutorial series on Proxmox.

While watching one of the videos, right as the creator said, "you can simply click the like button," the actual button on the page lit up with a smooth border animation that instantly grabbed my attention. I was so blown away that I called my girlfriend over just to show her (she didn't really care, but whatever). I just couldn't stop thinking about how a simple visual cue could pull a viewer's eyes exactly where you want them.

That’s what led me to build Questa. It basically bridges the gap between static embedded videos and actual user interaction.

How it works:

• You drop your video transcript into the dashboard.
• Questa detects potential "moments" and you map them to a predefined list of actions (like scrolling to a specific section, pulsing a CTA button, or opening a modal).
• You install a single lightweight script right before your closing body tag.
• When a user watches the video, the page reacts in real-time, exactly when and where you want it to happen during the playback.

This is version one, and I'm just getting ready to put it out there. I’d genuinely love your feedback, ideas, or even criticism on the concept.

Cheers.
