Plausible scores higher on the AgentReady, 48/100 against 46/100. They differ on 6 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

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

Plausible. Plausible Analytics is a simple, privacy-friendly alternative to Google Analytics.

Where Highlight is ahead

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

It also holds understand: structured api reference. Plausible misses it.

Where Plausible is ahead

Plausible passes authentication documented, and Highlight 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 and no mandatory sales call. Highlight misses those.

What neither does

Both fail mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, cli available, mcp integration available, 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. Highlight leads 87 to 73. Highlight misses mcp discoverable; Plausible misses llms.txt published, llms-full.txt / full agent docs, mcp discoverable.

Understand. Highlight leads 38 to 31. Highlight misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Plausible misses structured api reference, openapi / spec quality, 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. Plausible leads 52 to 25. Highlight misses self-service signup, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, cli available, mcp integration available; Plausible misses programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, cli available, mcp integration available.
