Sentry vs Unkey

Sentry scores higher on the AgentReady, 62/100 against 56/100. They differ on 10 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Sentry. Application monitoring software for error monitoring, tracing, and debugging.

Unkey. Unkey is a developer platform for modern APIs that unifies infrastructure, allowing developers to deploy APIs instantly, route traffic through global gateways, and understand usage in one place.

Where Sentry is ahead

Sentry passes llms-full.txt / full agent docs and mcp discoverable, and Unkey does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: agent-compatible signup flow and mcp integration available. Unkey misses those.

And on operate, agent compatibility verified. Unkey misses it.

Where Unkey is ahead

Unkey passes pricing understandable, and Sentry 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, free trial or free allowance, fast time to first request and copyable quickstart. Sentry misses those.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, 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.
