Prisma vs Vespa

Prisma scores higher on the AgentReady, 61/100 against 56/100. They differ on 5 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Prisma. Prisma is a complete TypeScript stack with one workflow: build your app and run all of it on your machine, then deploy it to the Prisma platform with one command.

Vespa. Vespa.ai develops the Vespa AI Search Platform, a distributed serving engine that unifies retrieval, ranking, machine learning inference, and real-time serving for business-critical AI applications.

Where Prisma is ahead

Prisma passes mcp discoverable, and Vespa does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: no mandatory sales call and mcp integration available. Vespa misses those.

Where Vespa is ahead

Vespa passes structured api reference and limits / constraints documented, and Prisma does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, agent-compatible signup flow, programmatic credential creation, structured, predictable output, machine-readable errors, 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.

Discover. Prisma leads 100 to 87. Prisma misses nothing; Vespa misses mcp discoverable.

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

Adopt is whether an agent can get a key and make its first successful call without a human in the loop. Prisma leads 80 to 55. Prisma misses agent-compatible signup flow, programmatic credential creation; Vespa misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, mcp integration available.

Operate. Prisma leads 39 to 35. Prisma misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; Vespa misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Prisma does not publish a machine-readable starting price and has a free tier. Vespa starts at $0.05/hour with no free tier.
