Score: 5.8/10 (Innovation: 5, Technical: 6, Documentation: 7, Utility: 5)

Rac-delta is an open, backend-agnostic protocol for differential directory synchronization, designed to efficiently sync application builds by transferring only modified file chunks. It's interesting because it abstracts storage backends via adapters and uses Blake3 hashing for performance, offering a flexible alternative to vendor-locked solutions.

Target audience: backend devs, devops
