Comparison Preset
Neither framework can be recommended for an enterprise environment due to significant risk factors. Mastra's 'NOASSERTION' license presents an unacceptable legal and compliance risk, making it a non-starter for any serious deployment. While Agno has a suitable Apache-2.0 license and an architecture designed for long-term maintainability, it currently has a known CRITICAL severity vulnerability. An enterprise cannot adopt a framework with such a severe security flaw until it is fully remediated. Therefore, neither option is a responsible choice at this time without major changes.
Overview
The bottom line — what this framework is, who it's for, and when to walk away.
Bottom Line Up Front
Agno provides a production-grade runtime for building, deploying, and managing agentic software, from single agents to coordinated teams and workflows. It features a scalable, stateless FastAPI backend, robust state management in your database, and a control plane for monitoring and governance. It emphasizes user ownership of data and infrastructure.
Mastra is a TypeScript framework designed for rapidly prototyping and confidently shipping AI agents. It integrates with popular web frameworks and supports a wide range of applications from customer service to DevOps automation.
