Fauna vs Turso

Turso scores higher on the AgentReady, 86/100 against 20/100. They differ on 24 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Fauna. Fauna is a distributed serverless database that combines document flexibility with relational power, automatic scaling, and zero operational overhead.

Turso. The Database for the Age of AI Agents.

Where Turso is ahead

Turso passes clear canonical domain, clear product positioning, public docs discoverable, llms.txt published, llms-full.txt / full agent docs, mcp discoverable and machine-readable metadata, and Fauna does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, openapi / spec quality, request examples provided, response examples provided and errors and status codes documented. Fauna misses those.

And on adopt, self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available and mcp integration available. Fauna misses those.

Finally, on operate, canonical workflow succeeds, structured, predictable output, machine-readable errors and observable execution. Fauna misses those.

What neither does

Both fail authentication documented, limits / constraints documented, 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. Turso leads 100 to 33. Fauna misses clear canonical domain, clear product positioning, public docs discoverable, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata; Turso misses nothing.

Understand. Turso leads 85 to 23. Fauna misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Turso misses authentication documented, limits / constraints documented.

Adopt is whether an agent can get a key and make its first successful call without a human in the loop. Turso leads 100 to 25. Fauna 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; Turso misses nothing.

Fauna misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; Turso misses retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.
