ConfigCat scores higher on the AgentReady, 63/100 against 62/100. They differ on 2 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

ConfigCat. ConfigCat is a hosted cross-platform feature flag and configuration management service that lets teams turn features ON/OFF after code deployment, target user segments, and perform % rollouts and A/B testing.

LaunchDarkly. The runtime control layer for AI development, de-risking releases, and enabling systems that heal and optimize themselves.

Where ConfigCat is ahead

ConfigCat passes fast time to first request and copyable quickstart, and LaunchDarkly does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

What neither does

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