Powersync vs TiDB Cloud

TiDB Cloud scores higher on the AgentReady, 65/100 against 50/100. 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

Powersync. PowerSync is a sync engine that consists of two components: a service that enables high-scalability partial data syncing and a set of client SDKs that manage client-side persistence, consistency, reactivity and syncing write operations back.

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 Powersync is ahead

Powersync 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. TiDB Cloud misses it.

Where TiDB Cloud is ahead

TiDB Cloud passes mcp discoverable, and Powersync 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. Powersync misses those.

And on adopt, mcp integration available. Powersync misses it.

Finally, on operate, structured, predictable output and agent compatibility verified. Powersync 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, fast time to first request, copyable quickstart, 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. Powersync misses mcp discoverable; TiDB Cloud misses clear canonical domain.

Understand. TiDB Cloud leads 38 to 23. Powersync 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. TiDB Cloud leads 65 to 55. Powersync misses programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, mcp integration available; 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 35. Powersync misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; TiDB Cloud misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable.

Pricing

Powersync starts at $0/month and has a free tier. TiDB Cloud does not publish one.
