[agent-protocol](https://agentprotocol.ai) reports 1.5k GitHub stars, 186 forks, and 49 open issues, last pushed Apr 8, 2025. [agentcanvas](https://vstorm.co) has 82 stars, 9 forks, and 0 open issues, last pushed Aug 1, 2026. Figures are from public GitHub metadata via [agent-protocol's repository](https://github.com/agi-inc/agent-protocol) and [agentcanvas's repository](https://github.com/vstorm-co/agentcanvas). | | [agent-protocol](/tools/agi-inc-agent-protocol.md) | [agentcanvas](/tools/vstorm-co-agentcanvas.md) | | --- | --- | --- | | Tagline | Common interface for AI agents | Visualize Pydantic AI agent workflows using Logfire traces | | Stars | 1,454 | 82 | | Forks | 186 | 9 | | Open issues | 49 | 0 | | Language | Python | Python | | Adopt for | agent-protocol provides a standardized interface for interacting with various AI agents regardless of their underlying tech stack, aiming to ease development, deployment, and benchmarking. | agentcanvas is for developers and AI practitioners who require detailed visual representations of Pydantic AI agent workflows, including cost breakdowns, extracted from Logfire traces. | | Persona | - | - | | Runtime | - | - | | License | MIT | MIT | | Categories | AI Agents | AI Agents, Evaluation & Observability | ## Trust and health _Sourced signals - not a safety guarantee.

See the comparison table for live GitHub stats and shared categories. ### When should I choose agent-protocol over agentcanvas? Choose agent-protocol over agentcanvas when Tags unique to agent-protocol: ai-agent, api, auto-gpt, gpt-4; When you want to ensure interoperability between different AI agents irrespective of the frameworks used by them; More GitHub stars (1.5k vs 82) - visibility, not fit. ### When should I choose agentcanvas over agent-protocol? Choose agentcanvas over agent-protocol when Tags unique to agentcanvas: ai-agents, genai, llm, logfire; Also covers Evaluation & Observability; To generate interactive HTML diagrams that provide visibility into the tools, sub-agents, tokens, and costs involved in running a Pydantic AI agent. ### 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 agentcanvas? If your AI agents are not built using Pydantic or do not utilize Logfire for tracing, as agentcanvas specifically works with these technologies. When the level of detail provided in the HTML diagrams is unnecessary or when you lack access to the required Logfire traces and associated tokens. ### Is agent-protocol or agentcanvas more popular on GitHub? agent-protocol has more GitHub stars (1,454 vs 82). Stars measure visibility, not whether either tool fits your constraints. ### Are agent-protocol and agentcanvas open source? Yes - both are open-source projects on GitHub (agent-protocol: MIT, agentcanvas: MIT). ### Where can I find alternatives to agent-protocol or agentcanvas? GraphCanon lists graph-backed alternatives at [agent-protocol alternatives](/tools/agi-inc-agent-protocol/alternatives) and [agentcanvas alternatives](/tools/vstorm-co-agentcanvas/alternatives) ([agent-protocol markdown twin](/tools/agi-inc-agent-protocol/alternatives.md), [agentcanvas markdown twin](/tools/vstorm-co-agentcanvas/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-vstorm-co-agentcanvas.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, agent-protocol or agentcanvas? agent-protocol: Dormant. agentcanvas: 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 agentcanvas?
