  • Wondering how you determined the E2B sandbox is Firecracker and not some other micro VM?

  • this reminds me that i'm long overdue for a weekend spent studying firecracker, the userfaultfd trick [0], and whatever zeroboot does

  • Hey everyone, I'm the CEO of the E2B - the VMs that the article talks about.

    Happy to answer your questions!

  • I took a look inside the VMs that a couple of the agent platforms are using. TLDR is they use firecracker with memory in git. I'm a big fan of the memory in git part it would be cool to see how the git history looks after I use it for a longer period of time. This is my first blog, I'm trying to document things publically as I learn, next I'll look more closely at the providers they are using under the hood (eg. e2b) so feel free to give advice on what to look for!

  • It's always, firecracker all the way down!

    Enjoyed the breakdown, honestly most of the things weren't really surprising.

    What was surprising to me was that instinct was just "agent slapped on top of markdown files in git", especially after seeing people talk about it so much. I expected at least a database or a graph or something "smart", but alas, its just three markdowns in a trenchcoat.

  • I was hoping for a whole catalogue of providers - doesn't amp have their own offering here "Orbs"?

    So, the interesting part for me was:

    "Who runs the fleet Anthropic, its own E2B, rented, third party"

    Like that's the only option, a bespoke platform or a rented SaaS for agent sandboxes.

    Disclaimer: I am tooting my own horn here - we built SlicerVM.com (Firecracker + Apple Virtualization framework) so that people don't have to pick between those two options.

    Especially when you have your own 1500-7000 USD MacBook right under your fingers.

    For remote access, (and this happened by accident one night in January) we built superterm.dev - initially as a tmux manager, then as a way to run and monitor agents. Our team sits with 6-24 long running tasks with dictation available, great mobile experience, and can combine both for secure agents + high amounts of feedback.

    If anyone's curious - Superterm has a CE edition - free for unlimited personal use. Slicer has a free trial and then a personal edition is available after that.
