Better Auth vs Descope

Descope scores higher on the AgentReady, 61/100 against 57/100. They differ on 11 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.

Descope. Descope is a passwordless authentication and user management service designed for developers.

Where Better Auth is ahead

Better Auth passes structured api reference, pricing understandable and limits / constraints documented, and Descope 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: free trial or free allowance. Descope misses it.

Where Descope is ahead

Descope 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, observable execution. Better Auth misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, 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

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.
