Peer-to-peer file transfer in the browser. No servers. No uploads. No limits.
Drop a file, share the link, done. Files travel directly between devices over end-to-end encrypted WebRTC data channels — they never touch a server.
- 🔒 End-to-end encrypted — WebRTC data channels secured by DTLS-SRTP. No middleman ever sees the bytes.
- 🚫 Zero server storage — files stream peer-to-peer; nothing is ever uploaded or stored.
- ♾️ No size limits — transfer up to 50 GB per file (browser-imposed cap).
- 📱 Cross-device — desktop ⇄ mobile ⇄ tablet, any modern browser.
- 🔗 Share via link or QR — room ID is encoded in the URL.
- ⏸️ Cancellable transfers — kill an in-flight transfer with one click.
- 🧹 Clear finished — sweep completed/cancelled transfers from the list.
- 🌈 Retrowave UI — neon glassmorphism, animated grid, scanlines.
- 🔁 Self-healing connections — auto-reconnect, ghost-peer detection, presence reconciliation.

Nostr relays only carry the SDP/ICE handshake. Once peers connect, every byte travels directly between devices.
Mobile networks (CGNAT, captive portals, flaky carriers) eat WebRTC connections for breakfast. Fileo fights back:
- Auto-reconnect on
iceConnectionStatefailed/disconnected. - Liveness ping after a peer joins — ghost peers trigger a clean rejoin.
- Cross-device presence reconciliation fixes asymmetric peer lists.
- Aggressive first-attempt rejoin with backoff when no peers appear.
- Multiple Nostr relays — if one is blocked or down, others carry the handshake.
- TURN fallback for symmetric NAT / CGNAT (common on mobile carriers).
