sshx

A secure web-based, collaborative terminal.

Features:

• Run a single command to share your terminal with anyone.
• Resize, move windows, and freely zoom and pan on an infinite canvas.
• See other people's cursors moving in real time.
• Connect to the nearest server in a globally distributed mesh.
• End-to-end encryption with Argon2 and AES.
• Automatic reconnection and real-time latency estimates.
• Predictive echo for faster local editing (à la Mosh).

Installation

Just run this command to get the sshx binary for your platform.

curl -sSf https://sshx.io/get | sh

Supports Linux and MacOS, on both x86_64 and arm64 architectures. The precompiled Linux binaries are statically linked.

CI/CD

You can also use sshx in continuous integration workflows to help debug tricky issues, like in GitHub Actions.

name: CI
on: push

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      # ... other steps ...

      - run: curl -sSf https://sshx.io/get | sh && sshx
      #      ^
      #      └ This will open a remote terminal session and print the URL. It
      #        should take under a second.

We don't have a prepackaged action because it's just a single command. It works anywhere: GitLab CI, CircleCI, CI on your Raspberry Pi, etc.

Development

Here's how to work on the project, if you want to contribute.

Building from source

To build the latest version of the client from source, clone this repository and run, with Rust installed:

cargo install --path crates/sshx

This will compile the sshx binary and place it in your ~/.cargo/bin folder.

Workflow

Install Rust 1.70+, Node v18, NPM v9, and mprocs. Then, run

$ npm install
$ mprocs

This will compile and start the server, an instance of the client, and the web frontend in parallel on your machine.

Deployment

The application servers are deployed on Fly.io.
