LStack installs per user and does not require administrator access or a global Node.js installation. The release artifact includes the Node.js runtime used by the dashboard and CLI.
LStack is pre-release and no artifact is publicly distributed yet. Evaluators must use a privately supplied artifact and checksum.

​
Prerequisites

Before installing LStack, you need:
  • A supported computer: Apple Silicon macOS or x86-64 Linux
  • curl, tar, and a SHA-256 utility
  • Docker Desktop on macOS or Docker Engine on Linux for workers and container-based project runtimes
  • Docker Compose v2 only when using a stack project runtime
  • A model endpoint that worker containers can reach
You do not need root access, a global Node.js installation, or a database server.

​
What the installer does

The installer verifies the artifact checksum before extraction, installs versioned files under ~/.lstack/, switches the active version atomically, and preserves existing configuration and data during reinstall or update.
Docker is not required to install or start the dashboard. Without Docker, execution-related surfaces remain unavailable until Docker is running.

​
Start the installed product

After installation, use the bundled CLI:
The dashboard binds to 127.0.0.1 and uses port 4700 by default. If that port is unavailable, LStack records and reports the fallback port.

Installation locations

Check platform support

Confirm that the target computer and Docker installation match a qualified configuration.
