Heroku vs Replicate

Replicate scores higher on the AgentReady, 82/100 against 63/100. They differ on 13 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Heroku. Heroku is a fully managed cloud application platform (PaaS) for building, deploying, and scaling apps.

Replicate. Platform to run and fine-tune AI models, deploy custom models, and generate images, speech, music, and video via API

Where Heroku is ahead

Heroku passes no mandatory sales call, agent-compatible signup flow and copyable quickstart, and Replicate does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

Where Replicate is ahead

Replicate passes openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided and errors and status codes documented, and Heroku does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: self-service signup, programmatic credential creation and free trial or free allowance. Heroku misses those.

And on operate, machine-readable errors. Heroku misses it.

What neither does

Both fail fast time to first request, 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

Adopt. Replicate leads 70 to 65. Heroku misses self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request; Replicate misses no mandatory sales call, agent-compatible signup flow, fast time to first request, copyable quickstart.

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