Chart Ledger Tool Compares Helm Chart Upgrades and Ranks Migration Guide Passages
Chart Ledger is an open-source tool built for the Hacktoberfest 2026 AI Challenge that helps engineers prepare for Helm chart upgrades. It compares before-and-after rendered Kubernetes manifests against a migration guide, such as the Kong 2.25.0 to 2.26.0 readiness-probe change, and produces a source-linked review. The tool ranks relevant documentation passages with an open-weight reranker model but does not execute upgrades or declare deployments safe, and every report is marked REVIEW REQUIRED. A hosted demo is available on Render, with source code licensed under Apache-2.0, though the public service handles only one inference at a time.
