Bucket Delta is a Python CLI tool for efficiently computing differences between two S3-compatible buckets, supporting both shallow (ETag/size) and deep (tags, metadata, WORM) comparisons. It's interesting for its enterprise-grade focus on resumable comparisons, multi-process architecture, and detailed reporting, addressing a specific pain point in data migration and compliance validation.

Target audience: devops, backend devs, data engineers
