Better Auth vs WorkOS

WorkOS scores higher on the AgentReady, 61/100 against 57/100. 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

Better Auth. A framework-agnostic, universal authentication and authorization framework for TypeScript.

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 Better Auth is ahead

Better Auth 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, pricing understandable and limits / constraints documented. WorkOS misses those.

And on adopt, free trial or free allowance. WorkOS misses it.

Where WorkOS is ahead

WorkOS passes clear canonical domain and llms-full.txt / full agent docs, and Better Auth does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: no mandatory sales call, agent-compatible signup flow, fast time to first request and copyable quickstart. Better Auth misses those.

And on operate, structured, predictable output and observable execution. Better Auth misses those.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, 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. Both sit at 87/100 here. Better Auth misses clear canonical domain, llms-full.txt / full agent docs; WorkOS misses clear product positioning.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Better Auth leads 54 to 23. Better Auth misses openapi / spec quality, request examples provided, response examples provided, errors and status codes 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 62. Better Auth misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart; WorkOS misses programmatic credential creation, free trial or free allowance.

Operate. WorkOS leads 50 to 24. Better Auth misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; WorkOS misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.
