Requirements

Development requirements

Requirement	Version	Notes
Node.js	>= 22	Required for building the extension
Yarn	1.x (Classic)	Package manager used by `@rancher/shell`
Rancher Manager	>= 2.10.0	Target platform for the extension
UI Extensions API	>= 3.0.0, < 4.0.0	Provided by Rancher 2.10+

Safari is not officially tested but generally works.

The Pastures Engine backend is optional. Without it, you can still explore every feature using demo mode. When connecting to a live Engine:

The Engine must be network-reachable from the browser (not from the Rancher server)
HTTPS is recommended for production deployments
An API key is required for Rancher Oracle; BYO model endpoints use their own authentication

If you just want to evaluate Pastures, enable demo mode in Settings — no Engine or API key required.
