Where Hanko is ahead

It also holds understand: structured api reference, authentication documented and limits / constraints documented. Hanko misses those.

And on adopt, agent-compatible signup flow. Hanko misses it.

What neither does

Both fail mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, cli available, mcp integration available, 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.
