Docker Pull Analyzer

A tool that analyzes Docker image pulls to show how much bandwidth is wasted due to layer invalidation. When a single dependency changes, Docker re-downloads entire layers even if most files are unchanged. The analyzer compares two Docker images and calculates actual data needed versus what standard docker pull transfers, with time savings estimates across different connection speeds.

Designed for teams deploying large images to bandwidth-constrained environments like robots, edge devices, and IoT systems. The maker says it was built with Claude Code. The tool includes interactive examples showing common scenarios: dependency updates, file moves, and metadata changes that trigger unnecessary re-pulls.
