Choose relay if…
- relay is primarily TypeScript; agentcanvas is Python.
- License: relay is Apache-2.0, agentcanvas is MIT.
- Tags unique to relay: agent-collaboration, agent-communication, real-time.
- When your application requires a robust hosted solution for real-time communication and orchestration of multiple AI agents
When NOT to use 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
Choose agentcanvas if…
- agentcanvas is primarily Python; relay is TypeScript.
- License: agentcanvas is MIT, relay is Apache-2.0.
- Tags unique to agentcanvas: agents, ai-agents, genai, llm.
- To generate interactive HTML diagrams that provide visibility into the tools, sub-agents, tokens, and costs involved in running a Pydantic AI agent.
When NOT to use 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.
