About:
diffoci is a command-line tool that performs semantic diffs between Docker and OCI container images. Unlike traditional file-level diffing, it understands container filesystems, metadata, and configurations to detect meaningful changes. This enables developers to verify image reproducibility and identify unexpected modifications in container builds.
Key Features:
  • Semantic diffing for container images
  • Support for Docker and OCI formats
  • Reproducible build verification
  • CLI-based workflow
  • Cross-platform compatibility
Use Cases:
  • Verifying reproducible container builds
  • Debugging image layer changes
  • Security auditing of container updates
  • CI/CD pipeline validation
Alternatives:
  • container-diff – Google's container-diff offers similar functionality but diffoci focuses on reproducibility and semantic analysis
  • dive – dive explores layer contents interactively, while diffoci performs automated comparisons between images
