CockroachDB vs TiDB Cloud

TiDB Cloud scores higher on the AgentReady, 65/100 against 51/100. 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

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

TiDB Cloud. TiDB Cloud is a cloud-native distributed SQL database service that provides infrastructure for infinite agents and infinite data, with support for AI applications, vector search, and multi-modal data platforms.

Where CockroachDB is ahead

CockroachDB passes clear canonical domain, and TiDB Cloud does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: pricing understandable. TiDB Cloud misses it.

And on adopt, free trial or free allowance, fast time to first request and copyable quickstart. TiDB Cloud misses those.

Where TiDB Cloud is ahead

TiDB Cloud 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, structured, predictable output, 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, 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. TiDB Cloud leads 93 to 87. CockroachDB misses search discoverable; TiDB Cloud misses clear canonical domain.

Understand. TiDB Cloud leads 38 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; TiDB Cloud misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. CockroachDB leads 71 to 65. CockroachDB misses agent-compatible signup flow, programmatic credential creation, official python sdk; TiDB Cloud misses programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, official python sdk.

Operate is whether an agent can run against it in production and recover when a call fails. TiDB Cloud leads 65 to 24. CockroachDB misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; TiDB Cloud misses 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. TiDB Cloud does not publish one.
