# Welcome to Chkk

> Agentic Upgrades for Cloud Native Software. Built for 100s of Cloud Native Projects like Istio, Keycloak, Consul, Cilium, and many more.

## What is Chkk?

Chkk automates every phase of your upgrade cycle — from **parsing release notes** and **diffing Helm charts** to **mapping CRD**, dependency, and config changes. Our agent flags breaking changes, EOL risks, and critical defects early and identifies incompatible components and API deprecations. It then couples these insights with **parameter-driven Blueprints**, orchestrated by **durable Workflows**, and executed through purpose-built Action Engines to deliver **safe, predictable upgrades** at scale for **100s of Cloud Native Projects**. Chkk accelerates upgrade execution by **more than 10×** while eliminating last-minute surprises.

## Why Chkk?

* **Pre-Verified, Safe Upgrade Workflows** - Chkk generates on-demand, agentic workflows that are tested and structured to eliminate risks.
* **Purpose‑Built Action Engines** – Convert high‑level intent into precise, auditable infrastructure changes across code, clusters, and collaboration systems.
* **AI-Powered Insights** - Uses up-to-date data from breaking changes, deprecated APIs, and dependency shifts to create a highly contextualized upgrade plan.
* **Lifecycle Management Agents** – Includes the **Upgrade Agent** for IDE integration (Cursor, Claude Code) that turns Upgrade Plans into environment‑aware IaC diffs and opens ready‑to‑merge pull requests.
* **Durable & Repeatable Execution** - Backed by a workflow engine that ensures safe, structured, and repeatable upgrades.
* **Broad Ecosystem Compatibility** - Works across cloud and on-prem environments and supports EKS, GKE, AKS, and hundreds of Cloud Native Projects. Check [Support](/overview/support-compatibility) for details.

## Safe Upgrades with Curated Workflows

Traditional runbooks and best practices quickly become outdated or inconsistently applied, leading to operational drift. Chkk Upgrade Copilot solves this by enabling teams to generate **Highly Contextualized, Agentic, Long-Running, Safe Upgrade workflows** on demand—ensuring every upgrade is structured, tested, and risk-free.

When a user initiates a request, Chkk Upgrade Copilot dynamically generates a contextualized **Upgrade Template**, tailored to their specific infrastructure. Behind the scenes, Chkk:

* **Reviews all release notes** to identify relevant breaking changes.
* **Analyzes dependencies and incompatibilities** to generate a pre-verified upgrade sequence, mitigating risks.
* **Tracks deprecated APIs, configurations, and features** to ensure compliance and stability.
* **Executes Actions** via Action Engines—applying IaC patches, creating pull requests, opening Jira tickets, running pre-/post-flight validations, and more.
* **Provides real-time visibility and actionable insights**, as a sequence of steps so teams can execute upgrades with confidence.
* **Continuously Governs & Closes**-the Workflow monitors until success criteria are met and emits audit-ready reports.

By transforming upgrade research, validation, and execution into **sequenced, repeatable workflows**, Chkk ensures that operational knowledge isn't just documented—it's **standardized, executed, and scaled across the organization**.
