Score: 8.5/10 (Innovation: 9, Technical: 9, Documentation: 8, Utility: 8)

Range is a tool that opens container images, Hugging Face repos, and other environments lazily without downloading them first, using a block cache and network block device to fetch only needed data. It enables fast access to large environments (e.g., 1TB) in seconds and remembers working sets for subsequent runs, potentially revolutionizing development workflows.

Target audience: backend devs, devops, data engineers, ML engineers
