The big motivation we had for trying to do this on a unikernel is actually the session pause/resume. The fast cold restart is a nice addition (or put the other way, a super slow restart would prohibit session pause/resume from being useful)

Are you referring to Unikraft Cloud's pricing? I'm not really sure, since I'm not affiliated. Maybe they'll chime in

Yes

Yeah, this is mostly just an OSS implementation for self-hosting! I'm not entirely sure what any of those companies use under the hood, in theory they could use this implementation if they wanted to gain the fast boot times, session reuse etc.

Haven't tried on a Lambda. Would be curious to know the results if you do!

It took us 8gb to get it up - maybe could be slimmed down if you took out the Anthropic Computer Use components, but browsers generally are pretty heavy.
