Turso. The Database for the Age of AI Agents.

Where PlanetScale is ahead

PlanetScale passes authentication documented, and Turso 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 operate: agent compatibility verified. Turso misses it.

Where Turso is ahead

Turso passes openapi / spec quality, request examples provided, response examples provided and errors and status codes documented, and PlanetScale 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: self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request and official python sdk. PlanetScale misses those.

And on operate, structured, predictable output and machine-readable errors. PlanetScale misses those.

What neither does

Both fail limits / constraints documented, 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.

Understand. Turso leads 85 to 46. PlanetScale misses openapi / spec quality, 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 55. PlanetScale misses self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request, official python sdk; Turso misses nothing.

Operate. Turso leads 59 to 56. PlanetScale misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Turso misses retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.
