Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 9, Utility: 6)

Keeper is an embedded cryptographic secret store for Go that provides a hardened, multi-level security model with Argon2id key derivation and XChaCha20-Poly1305 encryption. It's interesting because it offers fine-grained bucket isolation, tamper-evident audit chains, and multiple deployment options (library, HTTP handler, CLI) with production-ready remote KMS integrations.

Target audience: backend devs, devops
