Fly.io vs Prisma

Prisma scores higher on the AgentReady, 61/100 against 53/100. They differ on 7 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Fly.io. Fly.io provides real hardware-isolated Linux computers (called Sprites and Machines) for agents, evals, and tools, with a pay-as-you-go model where billing goes to zero when not in use.

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 Fly.io is ahead

Fly.io passes agent compatibility verified, and Prisma does not. That is operate, whether an agent can run against it in production and recover when a call fails.

Where Prisma is ahead

Prisma passes clear product positioning and llms-full.txt / full agent docs, and Fly.io 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, free trial or free allowance, fast time to first request and copyable quickstart. Fly.io 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. 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 80. Fly.io misses clear product positioning, llms-full.txt / full agent docs; Prisma misses nothing.

Understand. Both sit at 23/100 here. Fly.io 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 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. Fly.io misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart; Prisma misses agent-compatible signup flow, programmatic credential creation.

Operate. Fly.io leads 53 to 39. Fly.io misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Prisma misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Fly.io starts at $29/mo. Prisma does not publish one and has a free tier.

Which to pick

Prisma clears more of the signals an agent needs, so it is the safer default for unattended use. Full profiles: Fly.io and Prisma. Alternatives to each: Fly.io, Prisma.
