Installation

One-line install

curl -fsSL https://jalth.vinaypuppal.com/install.sh | sh

The installer downloads the latest release binary for your platform, verifies its checksum, and places jalth on your PATH.

Note

jalth ships as a compiled standalone binary. No Node.js, Bun, or other runtime is required on the target machine.

Prerequisites

Before creating or joining a mesh, install Cloudflare WARP on the device:

Platform	Install

Run jalth doctor to verify prerequisites. Use jalth doctor --fix to apply self-healing fixes where supported.

Upgrading

CLI self-upgrade

Full jalth upgrade (local binary replacement) is not yet implemented. Today, re-run the install script or download a release manually to update the CLI.
