Where ngrok is ahead

It also holds adopt: fast time to first request and copyable quickstart. ngrok misses those.

And on operate, idempotency support and agent compatibility verified. ngrok misses those.

What neither does

If your agent needs any of those, you will be building it yourself either way.
