Score: 6.8/10 (Innovation: 7, Technical: 7, Documentation: 7, Utility: 6)

SharkAuth is an open-source identity provider for AI agents, implementing OAuth 2.1 Token Exchange (RFC 8693) and DPoP (RFC 9449) in a single Go binary with embedded SQLite. It addresses the unique challenge of agent-to-agent delegation with cryptographically bound tokens and full audit trails, filling a gap in the AI infrastructure space.

Target audience: backend devs, devops, security engineers
