What each one is

turbopuffer. turbopuffer is a fast, object-storage native search engine providing vector and full-text search built on object storage.

Weaviate. Weaviate is an open-source, AI vector database designed to store and index both data objects and their vector embeddings, enabling advanced semantic search capabilities.

Where turbopuffer is ahead

turbopuffer passes no mandatory sales call, and Weaviate does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

It also holds operate: structured, predictable output and observable execution. Weaviate misses those.

Where Weaviate is ahead

Weaviate passes clear canonical domain and 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, errors and status codes documented and limits / constraints documented. turbopuffer misses those.

And on adopt, programmatic credential creation, cli available and mcp integration available. turbopuffer misses those.

Finally, on operate, machine-readable errors, idempotency support and rate-limit behavior predictable. turbopuffer misses those.

What neither does

Both fail openapi / spec quality, authentication documented, request examples provided, response examples provided, agent-compatible signup flow, retry behavior documented, 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.

Discover. Weaviate leads 100 to 80. turbopuffer misses clear canonical domain, mcp discoverable; Weaviate misses nothing.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Weaviate leads 62 to 23. turbopuffer misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Weaviate misses openapi / spec quality, authentication documented, request examples provided, response examples provided.

Adopt. Weaviate leads 80 to 60. turbopuffer misses agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available; Weaviate misses no mandatory sales call, agent-compatible signup flow.

Operate. Weaviate leads 53 to 47. turbopuffer misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; Weaviate misses structured, predictable output, retry behavior documented, observable execution, agent compatibility verified.

Pricing

turbopuffer starts at $16/month with no free tier. Weaviate does not publish one and has a free tier.
