Where ngrok is ahead

It also holds understand: pricing understandable. Kong misses it.

And on adopt, self-service signup, no mandatory sales call and free trial or free allowance. Kong misses those.

Finally, on operate, structured, predictable output and observable execution. Kong misses those.

What neither does

Both fail 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, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
