What each one is
Chroma. Open-source search infrastructure for AI.
turbopuffer. turbopuffer is a fast, object-storage native search engine providing vector and full-text search built on object storage.
Where Chroma is ahead
Chroma passes mcp discoverable, and turbopuffer 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, openapi / spec quality, authentication documented, request examples provided, response examples provided and errors and status codes documented. turbopuffer misses those.
And on adopt, agent-compatible signup flow, programmatic credential creation, cli available and mcp integration available. turbopuffer misses those.
Finally, on operate, machine-readable errors. turbopuffer misses it.
Where turbopuffer is ahead
turbopuffer passes official typescript sdk and official python sdk, and Chroma 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 clear canonical domain, limits / constraints documented, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. 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.

Operate. Chroma leads 59 to 47. Chroma misses retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; turbopuffer misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.
