Show HN: SecureShare – P2P file/text sharing with no size limits, no servers
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?
