Marqo vs Mastra

Mastra scores higher on the AgentReady, 42/100 against 38/100. 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

Marqo. Marqo is a search and product discovery platform built for ecommerce that uses LLM-based retrieval to continuously learn from shopper behavior and surface relevant, high-converting products.

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

Where Marqo is ahead

Marqo passes structured api reference and pricing understandable, and Mastra does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: free trial or free allowance and official python sdk. Mastra misses those.

And on operate, observable execution. Mastra misses it.

Where Mastra is ahead

Mastra passes clear canonical domain, clear product positioning, llms.txt published and mcp discoverable, and Marqo does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: copyable quickstart, cli available and mcp integration available. Marqo misses those.

What neither does

Both fail llms-full.txt / full agent docs, 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, agent-compatible signup flow, 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.

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 is whether an agent can find the product at all without being told it exists. Mastra leads 93 to 53. Marqo misses clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable; Mastra misses llms-full.txt / full agent docs.

Understand. Marqo leads 38 to 15. Marqo misses openapi / spec quality, authentication documented, 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. Mastra leads 35 to 25. Marqo misses self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available, mcp integration 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. Marqo leads 35 to 24. Marqo misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; Mastra misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.

Pricing

Marqo does not publish a machine-readable starting price with no free tier. Mastra does not publish one.

Signal by signal

Which to pick
