Agno vs Mastra

Agno scores higher on the AgentReady, 65/100 against 42/100. They differ on 12 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Agno. Agno is a self-driving agent platform that runs in your cloud.

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

Where Agno is ahead

Agno 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: authentication documented and pricing understandable. Mastra misses those.

And on adopt, self-service signup, no mandatory sales call, free trial or free allowance and official python sdk. Mastra misses those.

Finally, on operate, structured, predictable output, observable execution and agent compatibility verified. Mastra misses those.

Where Mastra is ahead

Mastra passes copyable quickstart and cli available, and Agno 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, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, fast time to first request, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. Agno leads 100 to 93. Agno misses nothing; Mastra misses llms-full.txt / full agent docs.

Understand. Agno leads 31 to 15. Agno misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Mastra misses structured api reference, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Agno leads 65 to 35. Agno misses agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available; Mastra misses self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, official python sdk.

Operate is whether an agent can run against it in production and recover when a call fails. Agno leads 65 to 24. Agno misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Mastra misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.

Pricing

Agno starts at $0/mo and has a free tier. Mastra does not publish one.
