I Found 9 Agent Identity Projects on GitHub. Only 2 Have Real Users.

I searched GitHub for "agent identity protocol" this week and found 9 projects created in 2026 alone. The agent identity space is exploding. Everyone agrees agents need cryptographic identity. Almost nobody has shipped anything people actually use. Here is what I found: The Landscape Project Stars Status soulkeep 35 Identity preservation — interesting concept, no production API open-agent-auth 29 Enterprise auth framework — corporate, no public registration openagentidentityprotocol 18 Zero-trust for agents — readme-stage, no running service grantex 11 Identity + audit infra — early stage atproto-agent-network 8 AT Protocol for agents — experimental agent-passport-system 5 Crypto identity + delegation — spec-stage agent-attestation-protocol 2 Verification protocol — early SNAP Protocol 2 Signed agent-to-agent communication — early And then there is AIP — the one I built. 13 registered agents, 5 active vouch chains, 22 encrypted messages exchanged, live API, PyPI package, MCP server.
