"Uh-Oh!” 🌼 Who else still hears this sound in their sleep?

Let’s be honest: Modern messaging is efficient, but it’s become… soulless. Everything is clean, minimal, and predictable. That’s why I spent the last few weeks turning back the clock—while keeping the tech firmly in 2026.

I built ICQ Retrogram. 💻✨

It’s a fully functional multi-messenger for WhatsApp and Telegram, but with the exact look and feel of the legendary ICQ 5.

What’s under the hood?

Frontend: Pure retro vibes, including the original status icons, window skins, and that iconic lime-green flower.

Backend: Seamless integration of modern messenger APIs, making sure the nostalgia actually works in your daily life.

The "Why": Because chatting should be fun again. UI design can be more than just "white space and sans-serif fonts."

I’ve documented the entire journey—from the initial spark to the technical hurdles—in a new Medium article.

I’m curious: Which old-school feature do you miss the most? The "Invisible" mode? The "Nudge"? Or just the thrill of someone coming online?
