Hey folks, I made Wallper - a small macOS app for 4K live wallpapers. Built it after switching from Windows and missing Wallpaper Engine. It’s open-source, free to try, and I’d love to hear what you think: wallper.app

When do you understand that it’s time to go for the next project?

If you need a work–life balance before you’ve built anything you’re not built for this.

I’ve got an app idea. But how do I actually validate if people want it and if they’d pay for it? What’s your go-to method?

Should I delete posts that didn’t get any engagement?

My first ever app wallper.app just passed 5,000 active users! And it’s only been a month since launch. This is just the beginning, not slowing down any time soon. Let’s see how far we can take this :)

Would you rather go solo or build with someone else? Why?

The first version won’t be perfect. But the second one won’t exist if you don’t ship the first.

What tiny decision did you make that accidentally changed your entire life?

Can’t believe this… Over 20,000 people have already visited the site of my first-ever app - and it’s only been a month since launch. I never imagined so many strangers would care about something I made. Let’s see how far it can go. 🚀

No ideas? Feeling blocked? Stuck on your startup? Take a walk. Touch grass. Let your brain breathe. You’ll come back lighter - and clearer.

Startup idea: AI that writes your “building in public” tweets based on your Git commits

$3K+ in the first month. (1 USD = 21.26 CZK if you’re wondering about the screenshot.) Still hard to believe, to be honest. Built my first ever app, launched it without any audience or budget No idea what I was doing at first. Just kept showing up. And somehow… it worked.…

how do you post regularly on x and still get real work done?

I'm not just building a business... I'm building proof that fun and freedom can coexist.

If you need motivation all the time, maybe your goal isn’t the right one.

This started as a note on my iPhone. Now it’s: - First SaaS ever. - 4,626 active users. - Launched 2 weeks ago. - 100–200 new users daily, all on autopilot. I’m 19 And this is just the beginning.

Building in public isn’t just marketing - it’s how you build a movement around what you’re building. @marc_louvion does this so well. People don’t just follow the product, they follow the process. What would happen if you built trust before features?
