ZeroID is an open-source identity platform by Highflame that gives every AI agent in a multi-agent system a cryptographically verifiable identity with explicit delegation chains. Built on OAuth 2.1, RFC 8693 token exchange, and SPIFFE-style identity URIs, it solves the attribution problem when orchestrator agents spawn sub-agents: who authorized what, and can you prove it? Scope automatically attenuates at each delegation hop — sub-agents can't exceed their orchestrator's permissions. Real-time revocation via the OpenID Shared Signals Framework propagates instantly through the entire delegation chain. SDKs available for Python, TypeScript, and Rust with integrations for LangGraph, CrewAI, and Strands. Announced publicly April 8, picked up by Help Net Security April 13. This is v0.1 infrastructure for a problem the industry is just starting to take seriously.
Reviewer scorecard
“The per-request pricing model is perfect for side projects — you literally pay nothing until you have traffic. Redis commands at $0.2/100K is incredibly cheap.”
“Infrastructure the agentic ecosystem desperately needs and nobody has properly solved. The RFC 8693 token exchange is the right approach — maps cleanly onto service-to-service auth in microservices. Automatic scope attenuation is the critical safety property: no sub-agent can exceed what its orchestrator was allowed. Apache 2.0, Docker Compose setup, real SDK support.”
“At high scale, per-request pricing can get expensive vs a fixed Redis instance. Know your traffic patterns. For most indie hackers and startups, it's a no-brainer.”
“This is v0.1 infrastructure for a problem most teams aren't hitting at scale yet. The CLI is 'planned.' Human-in-the-loop approvals are 'planned.' The hosted version at auth.highflame.ai adds a third-party trust dependency for something that's supposed to be about trust. Worth watching, not worth building on in production.”
“Upstash is doing for Redis what Neon did for Postgres — making it serverless-native. The QStash message queue is an underrated piece of the puzzle.”
“We're in the window where the identity layer for the agentic era is being defined. ZeroID's bet on existing OAuth/OIDC infrastructure rather than inventing a new protocol is smart — enterprise security teams won't reject it outright. The real-time revocation propagation is the feature that matters most when something goes wrong with an autonomous agent.”
“Deep infrastructure — identity tokens, delegation chains, revocation lists. It's solving a real problem but it's not something a non-engineer can evaluate or use directly. If you're a content creator, this is plumbing that will hopefully get embedded into the platforms you use. Check back when it's a managed service with a dashboard you can navigate.”
