Can any one review this project

Hi everyone,
I've been working on PasteDB a paste sharing platform built for developers. My goal isn't just to make another Pastebin clone, but to gradually build a place where developers can share code and access useful developer tools.
Current features include:
⚡ Fast paste creation (no account required)
END TO END ENCRYPTION FOR PRIVATE AND UNLISTED PASTES
🎨 Syntax highlighting
▶️ Built-in code execution for supported languages
📝 Markdown preview
📱 Mobile-friendly UI
📷 QR code generation and QR scanner
🔒 Password-protected and expiring pastes
🔍 Explore page and search
🌙 Light/Dark theme
API support
Nearby transfer or share
🚫 No ads , no captcha and for FREE!

My long-term vision is to make PasteDB a hub for developer utilities, not just paste sharing.
I'm not looking to sell anything—I genuinely want feedback from developers.
If you had 2 minutes to try it, I'd love to know:
What was your first impression?
What would stop you from using it instead of Pastebin or GitHub Gist?
Which feature should I improve first?
Thanks for taking a look!
