CockroachDB vs PlanetScale

PlanetScale scores higher on the AgentReady, 64/100 against 51/100. They differ on 9 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

CockroachDB. CockroachDB is a cloud-agnostic, PostgreSQL compatible database built for modern applications delivering unmatched uptime, scale and compliance anywhere in the world.

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.

Where CockroachDB is ahead

CockroachDB passes self-service signup, free trial or free allowance and fast time to first request, 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.

Where PlanetScale is ahead

PlanetScale passes search discoverable, and CockroachDB 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 and authentication documented. CockroachDB misses those.

And on adopt, agent-compatible signup flow. CockroachDB misses it.

Finally, on operate, observable execution and agent compatibility verified. CockroachDB misses those.

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, official python sdk, 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.

Discover. PlanetScale leads 100 to 87. CockroachDB misses search discoverable; PlanetScale misses nothing.

Understand. PlanetScale leads 46 to 23. CockroachDB misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; PlanetScale misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. CockroachDB leads 71 to 55. CockroachDB misses agent-compatible signup flow, programmatic credential creation, official python sdk; PlanetScale misses self-service signup, 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. PlanetScale leads 56 to 24. CockroachDB misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; PlanetScale misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable.

Pricing

CockroachDB does not publish a machine-readable starting price and has a free tier. PlanetScale starts at $5/mo.
