Fauna vs Prisma

Prisma scores higher on the AgentReady, 61/100 against 20/100. They differ on 15 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Fauna. Fauna is a distributed serverless database that combines document flexibility with relational power, automatic scaling, and zero operational overhead.

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.

Where Prisma is ahead

Prisma passes clear canonical domain, clear product positioning, public docs discoverable, llms.txt published, llms-full.txt / full agent docs, mcp discoverable and machine-readable metadata, and Fauna does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: self-service signup, no mandatory sales call, fast time to first request, copyable quickstart, cli available and mcp integration available. Fauna misses those.

And on operate, canonical workflow succeeds and observable execution. Fauna misses those.

What neither does

Both fail structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints 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 is whether an agent can find the product at all without being told it exists. Prisma leads 100 to 33. Fauna misses clear canonical domain, clear product positioning, public docs discoverable, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata; Prisma misses nothing.

Understand. Both sit at 23/100 here. Fauna misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Prisma misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Prisma leads 80 to 25. Fauna misses self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available, mcp integration available; Prisma misses agent-compatible signup flow, programmatic credential creation.

Operate. Prisma leads 39 to 0. Fauna misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; Prisma misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Fauna starts at $150/mo with no free tier. Prisma does not publish one and has a free tier.
