P2P Ghost Tunnel

Bypass ngrok entirely. Generate a secure WebRTC tunnel to stream your localhost directly to a client's browser without any intermediary servers.

P2P Ghost Tunnel

Bypass ngrok. Establish a direct Peer-to-Peer WebRTC Data Channel between two browsers. Zero servers, zero latency, impossible to intercept.

What is P2P Ghost Tunnel?

P2P Ghost Tunnel establishes a direct, encrypted WebRTC connection between your browser and another device, entirely bypassing centralized servers. It's designed for transferring logs, sensitive payloads, or securely chatting without leaving a trace.

Because the signaling relies on a minimal exchange of ICE candidates (which can be done manually or via a temporary signaling channel), the resulting connection is strictly peer-to-peer.

How to use this tool

  1. Generate an Offer from Device A and copy the SDP string.
  2. Paste the Offer into Device B to generate an Answer.
  3. Copy the Answer back to Device A to establish the connection.
  4. Once connected, start sending encrypted data or files.

Frequently Asked Questions

Is the data routed through Castov servers?
No. All data flows directly between peers using WebRTC data channels. We do not use any TURN/STUN servers that intercept data.
What happens if both devices are behind strict NATs?
Direct connection might fail without a TURN server. Currently, this tool requires at least one peer to have permissive NAT traversal or use a local network.
