Well — three, and you only do the first two. Signing up and signing in are the same thing: your email, a link, the editor.
Start free — send me the linkTakes about a minute, most of it your inbox.
That's the whole form. No password to invent, no card, no project wizard, no cloud account to link.
It works once and expires in fifteen minutes. Clicking it is both signup and sign-in — there's no separate registration.
A working example is already deployed, your subdomain is already serving it with TLS, and every request to it is already being recorded for replay.
One app on its own TLS subdomain, a schemaless transactional database, static hosting, and seven days of full deterministic replay — free while your app is active, with no card on file. When you need more, one flat price covers your whole team.
