# Introduction

> Pastures brings AI-powered diagnostics and fleet intelligence to Rancher Manager.

Pastures is an open-source Rancher UI extension that adds AI-powered diagnostics, fleet intelligence, and operational tooling directly into Rancher Manager.

## What is Pastures?

Pastures extends Rancher with capabilities that don't exist in the base platform:

* **AI diagnostics** grounded in 48,000+ real K3s, Rancher, RKE2, and Harvester issue resolutions
* **Fleet intelligence** with health scoring, drift detection, and version tracking
* **GPU fleet management** for AI/ML workloads across clusters
* **Harvester HCI** integration for VM lifecycle management
* **Security posture** via CIS benchmarks and NeuVector integration
* **Operations tooling** for etcd backup, upgrade risk assessment, and audit logging

The extension is a pure UI client — it contains zero proprietary logic. All AI capabilities come from either the hosted Rancher Oracle service or your own model via any OpenAI-compatible endpoint.

## How is Pastures different from Rancher Prime / Liz?
