See the comparison table for live GitHub stats and shared categories. ### When should I choose relay over agent-protocol? Choose relay over agent-protocol when relay is primarily TypeScript; agent-protocol is Python; License: relay is Apache-2.0, agent-protocol is MIT; Tags unique to relay: agent-collaboration, agent-communication, real-time; Also covers Evaluation & Observability; When your application requires a robust hosted solution for real-time communication and orchestration of multiple AI agents. ### When should I choose agent-protocol over relay? Choose agent-protocol over relay when agent-protocol is primarily Python; relay is TypeScript; License: agent-protocol is MIT, relay is Apache-2.0; Tags unique to agent-protocol: agents, ai-agent, api, auto-gpt; When you want to ensure interoperability between different AI agents irrespective of the frameworks used by them. ### When should I avoid relay? If your project mandates an on-premise deployment or strict control over the messaging infrastructure due to regulatory requirements, as relay operates exclusively as a hosted service In scenarios where proprietary communication protocols cannot be adapted to work with relay's architecture for seamless integration ### When should I avoid agent-protocol? If you are developing an isolated system with no intention to communicate or integrate with other AI agents outside this scope. When working in environments where specific, proprietary interfaces provide significantly better performance or features than adhering to a generic protocol could offer. ### Is relay or agent-protocol more popular on GitHub? agent-protocol has more GitHub stars (1,454 vs 843). Stars measure visibility, not whether either tool fits your constraints. ### Are relay and agent-protocol open source? Yes - both are open-source projects on GitHub (relay: Apache-2.0, agent-protocol: MIT). ### Where can I find alternatives to relay or agent-protocol? GraphCanon lists graph-backed alternatives at [relay alternatives](/tools/agentworkforce-relay/alternatives) and [agent-protocol alternatives](/tools/agi-inc-agent-protocol/alternatives) ([relay markdown twin](/tools/agentworkforce-relay/alternatives.md), [agent-protocol markdown twin](/tools/agi-inc-agent-protocol/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/agentworkforce-relay-vs-agi-inc-agent-protocol.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, relay or agent-protocol? relay: Very active. agent-protocol: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for relay and agent-protocol? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [relay trust report](/tools/agentworkforce-relay/trust); [agent-protocol trust report](/tools/agi-inc-agent-protocol/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=agentworkforce-relay`](/api/graphcanon/graph?tool=agentworkforce-relay) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
