AutoGen (AG2) vs Mastra

AutoGen (AG2) scores higher on the AgentReady, 53/100 against 42/100. They differ on 7 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

AutoGen (AG2). AG2 (formerly AutoGen) is an open-source multi-agent AI framework and AgentOS for building, orchestrating, and evolving systems of AI agents.

Mastra. Mastra is a TypeScript framework for building AI agents and applications.

Where AutoGen (AG2) is ahead

AutoGen (AG2) passes llms-full.txt / full agent docs, and Mastra does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: pricing understandable. Mastra misses it.

And on adopt, agent-compatible signup flow, free trial or free allowance and official python sdk. Mastra misses those.

Finally, on operate, observable execution. Mastra misses it.

Where Mastra is ahead

Mastra passes cli available, and AutoGen (AG2) does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

What neither does

Both fail structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, no mandatory sales call, programmatic credential creation, fast time to first request, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
