I've been struggling with sleep for a while and couldn't find a simple, lightweight browser extension that just works. So I built one.
**Uykucu** lets you mix 48+ ambient sounds (rain, forest, café noise, white noise, brown noise...) directly in Chrome. Everything is synthesized in real-time using the Web Audio API — meaning zero audio file downloads and it works completely offline.
**Features:**
- 🎚️ Mix multiple sounds with individual volume sliders
- 😮💨 4-7-8 breathing exercise with animated guide
- ⏱️ Sleep timer (15 min – 2 hours) with automatic fade-out
- 🌍 Turkish / English language support
- 💤 Runs in background while you browse
- 100% free, no account needed
I'm a solo indie developer and this is a passion project. Would love any feedback — bugs, feature requests, or just what you think!
