BitBang CLI enables browser-based remote access to machines behind NAT without accounts
Key points
- BitBang CLI provides remote shell, file transfer, and network proxy.
- It works from behind NAT, CGNAT, and locked-down networks.
- Connections are end-to-end encrypted and peer-to-peer via WebRTC/DTLS.
- No account or port forwarding is required for use.
Simplified Remote Access
BitBang CLI is a new static binary tool designed for remote machine access. It allows users to open an interactive shell, browse and transfer files, and access web applications on a remote machine's network directly from any web browser. The tool removes the need for port forwarding, complex configurations, or creating user accounts.
How It Works
To initiate a connection, users install the BitBang CLI on the target machine and run `bitbang serve`. This command generates a URL or a short pairing code. The connecting party can then access the remote machine via a browser using the provided URL or by entering the pairing code, which is verified with a second six-digit number for security. The connection is end-to-end encrypted and peer-to-peer, with a signaling server only introducing the two endpoints before stepping aside.
Addressing Network Limitations
BitBang addresses common difficulties in remote access, particularly for machines behind NAT, Carrier-Grade NAT (CGNAT), or restricted corporate/university networks. Unlike traditional SSH, which often requires an inbound path that is frequently unavailable, BitBang operates without needing an open port, VPN, or tunnel daemon. This functionality is achieved using WebRTC as the transport layer, similar to how SSH uses TCP for its `sshd`, `ssh`, and `scp` commands.
Privacy and Design Principles
The tool emphasizes privacy by design, utilizing WebRTC/DTLS for peer-to-peer traffic. The signaling server does not intercept or store user data, and if a direct peer-to-peer connection is not possible, a TURN relay carries only ciphertext. BitBang operates without requiring user accounts or collecting telemetry data, aligning with a privacy-focused approach to remote access.

BitBang CLI is a new tool that provides remote access to machines behind Network Address Translation (NAT) from a web browser, offering an interactive shell, file transfer, and network proxy capabilities. This tool simplifies remote access by eliminating the need for port forwarding, configuration, or user accounts, addressing common challenges with traditional remote access methods like SSH in restricted network environments.
