@rgarcia and @sjmiller609 have been working on a multi-hypervisor VM runtime to support our work as serverless cloud browser infra. It now runs in our prod services managing >1 mil…

firecracker is an obvious place to start because it offers best-in-class support fast cold starts and hard isolation. we can't speak to what exactly the other browser infra provide…

As part of launching our MCP server, we wrote a short blog post about some of our technical decisions and limitations of the current landscape. The space still feels very early, so…

Thank you! Just saw your GH, will check out your WebRTC work more deeply :)

Hey HN, We’ve been building on top of our browser-unikernel repo [0] and wanted to replace the noVNC remote GUI with something much faster. NoVNC is okay but it’s super laggy with …

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 re…

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…

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 comp…

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

Yeah, there are some nuances to Unikraft Cloud that their team did to get it running. I'll see if they can chime in and shed some light!

Thank you!

Thank you! Yeah, the current implementation basically performs the same as a Docker container (i.e. not much). The interface is the same, so you can use BU/Playwright/Puppeteer's h…

From what we've seen, micro VMs could probably do something very fast too (150ms?) but we thought 20ms was pretty crazy.

Thank you!

(OP) Happy to answer any questions! Some things we're still exploring: - Mounting persistent storage for file i/o - Replacing noVNC with a faster alternative Would love feedback, e…

We’ve been building infrastructure to spin up browsers for AI agents. Originally, we built[0] it as a pool of warm Docker containers running Chromium, exposing: - Chrome DevTools P…
