Kernel vs WorkOS

Kernel scores higher on the AgentReady, 89/100 against 61/100. They differ on 19 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Kernel. Kernel provides crazy fast, open source browser infrastructure for AI agents to access the internet.

WorkOS. WorkOS is a set of building blocks for quickly adding enterprise features to your app, providing a single, elegant interface that abstracts dozens of enterprise integrations.

Where Kernel is ahead

Kernel passes clear product positioning, and WorkOS 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, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented and limits / constraints documented. WorkOS misses those.

And on adopt, programmatic credential creation and free trial or free allowance. WorkOS misses those.

Finally, on operate, machine-readable errors, retry behavior documented, rate-limit behavior predictable and agent compatibility verified. WorkOS misses those.

Where WorkOS is ahead

WorkOS passes authentication documented, and Kernel 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: no mandatory sales call, agent-compatible signup flow, fast time to first request and copyable quickstart. Kernel misses those.

What neither does

Both fail idempotency support. 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. Kernel leads 100 to 87. Kernel misses nothing; WorkOS misses clear product positioning.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Kernel leads 92 to 23. Kernel misses authentication documented; WorkOS misses structured api reference, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. WorkOS leads 85 to 71. Kernel misses no mandatory sales call, agent-compatible signup flow, fast time to first request, copyable quickstart; WorkOS misses programmatic credential creation, free trial or free allowance.

Operate. Kernel leads 94 to 50. Kernel misses idempotency support; WorkOS misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Kernel starts at $0/mo and has a free tier. WorkOS does not publish one.
