PlanetScale vs Xata

Xata scores higher on the AgentReady, 70/100 against 64/100. They differ on 5 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

PlanetScale. PlanetScale provides the world's fastest and most scalable cloud databases, offering fully-managed Vitess and PostgreSQL clusters with exceptional speed, reliability, and horizontal scalability through sharding.

Xata. A Postgres platform with instant branching and scale-to-zero compute.

Where PlanetScale is ahead

PlanetScale passes authentication documented, and Xata does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

Where Xata is ahead

Xata passes self-service signup, free trial or free allowance, fast time to first request and official python sdk, and PlanetScale 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 openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, structured, predictable output, 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.

Understand. PlanetScale leads 46 to 38. PlanetScale misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Xata misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes 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. Xata leads 90 to 55. PlanetScale misses self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request, official python sdk; Xata misses programmatic credential creation.

Operate. PlanetScale leads 56 to 53. PlanetScale misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Xata misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable.

Pricing

PlanetScale starts at $5/mo. Xata starts at $0.012/hr and has a free tier.
