See the comparison table for live GitHub stats and shared categories. ### When should I choose agent-protocol over simulate-sdk? Choose agent-protocol over simulate-sdk when License: agent-protocol is MIT, simulate-sdk 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 choose simulate-sdk over agent-protocol? Choose simulate-sdk over agent-protocol when License: simulate-sdk is Apache-2.0, agent-protocol is MIT; Tags unique to simulate-sdk: agentic-ai, evaluation, simulate, testing-tools; Also covers Evaluation & Observability; When you need to test AI agents in realistic voice interaction scenarios, ensuring that the agent's responses are accurate and timely under various conditions. ### 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. ### When should I avoid simulate-sdk? If your project does not involve AI-driven voice interactions, using simulate-sdk would be unnecessary as it specifically caters to voice-based testing scenarios. For non-enterprise applications where the focus is on text-based interaction evaluations rather than voice-based ones, this SDK may offer excess capabilities that are not needed. ### Is agent-protocol or simulate-sdk more popular on GitHub? agent-protocol has more GitHub stars (1,458 vs 59). Stars measure visibility, not whether either tool fits your constraints. ### Are agent-protocol and simulate-sdk open source? Yes - both are open-source projects on GitHub (agent-protocol: MIT, simulate-sdk: Apache-2.0). ### Where can I find alternatives to agent-protocol or simulate-sdk? GraphCanon lists graph-backed alternatives at [agent-protocol alternatives](/tools/agi-inc-agent-protocol/alternatives) and [simulate-sdk alternatives](/tools/future-agi-simulate-sdk/alternatives) ([agent-protocol markdown twin](/tools/agi-inc-agent-protocol/alternatives.md), [simulate-sdk markdown twin](/tools/future-agi-simulate-sdk/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/agi-inc-agent-protocol-vs-future-agi-simulate-sdk.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, agent-protocol or simulate-sdk? agent-protocol: Dormant. simulate-sdk: Steady. 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 agent-protocol and simulate-sdk? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [agent-protocol trust report](/tools/agi-inc-agent-protocol/trust); [simulate-sdk trust report](/tools/future-agi-simulate-sdk/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=agi-inc-agent-protocol`](/api/graphcanon/graph?tool=agi-inc-agent-protocol) - 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/_
