This is a sandbox experience folks over at Sentry.io created.
I like the navbar CTAs with a big "Documentation" button in there.
Reminds me that I can go and see it when I need it.
But I also get those conversion focused "Request a demo" and "Start a trial" for when I am ready.
On top of that I get tours and help in the sidebar for when I get stuck.
.... and the whole thing is gated behind a work email which I don't love.
But having that work email let's you nurture (and Sentry is known for awesome emails).
Plus it does help sales. If anything it is an additional signal for your account scoring models.
But if you are going to gate a sandbox, make sure to show all that value behind the modal like Sentry did.
With that I can feel compelled to type in that email.
