Test agents on Mastra, Agno, and 10+ other frameworks

Scenario is framework-agnostic, supporting any agent architecture through the AgentAdapter interface.

This lets you easily connect with Mastra, Agno, LangGraph, CrewAI, and over 10 other LLM and AI frameworks with a simple async call() method.

It supports multiple response formats including OpenAI messages.

You can also integrate low-code tools, like Langflow, n8n, and Dify, for comprehensive testing coverage across your entire AI stack.

This gives you the ability to test any agent regardless of the framework you're using without modifying their code.
