I built SecureShare to solve a common problem I faced: securely sharing files between devices without size limits or intermediary servers.

What it does:

- Direct P2P file/text/folder sharing using WebRTC - No file size limits (only constrained by local disk space) - No registration required - All data stays on your devices (no server storage) - Supports multiple simultaneous receivers - Custom retrieval IDs and QR codes for easy sharing - Works across platforms, mobile-optimized

Technical details:

- Built with Next.js + Tailwind + shadcn/ui - Backend: Node.js + Redis (minimal, only for signaling) - WebRTC for direct P2P connections - DTLS encryption for all transfers - Files stream directly to disk

Background: I'm a C++ algorithm engineer and father of two who built this in my spare time over 4 months while learning full-stack development. Used AI pair programming extensively, which was an interesting learning experience.

I'd love feedback from the HN community. What features would make this more useful for your workflow?
