Hi, Alex from Unikraft here. One clarification: Browser-Use didn't move away from Unikraft because of any limitation around browser startup times, snapshotting, scale-to-zero, or browser-level autoscaling. Those capabilities worked w

Howdy! We are hard at work at improving the DX, and as a result we've been working on a brand new CLI. We haven't made any announcements yet, but it's already open-source for early adopts if you'd like to give it a try!

Hey! Co-founder of Unikraft here. Unikraft aims to offer a Linux-compatible environment (so it feels familiar) with the ability to strip out unnecessary internal components in order to improve both boot-time/runtime performance and ope

This project operates by first building the webassembly module into an ELF binary and then statically linking this against the Mewz library OS in order to become a unikernel binary. It looks still very early days in terms of supporting all

Hi! Thanks for the feedback! Good point on the Kraftfile syntax and as you've seen, there is a reference document. We can make sure to place a link to this in all guides. The term "KraftCloud Specification" is in fact incorr

Correct -- and you can run multiple kernels on the machine with virtualization extensions. Even Docker Desktop does this. You'd do this for _real_ isolation purposes.

Containers are perfect for build environments and for creating the root filesystem. The issue is that the kernel these days are super bulky and are intended for multi-user, multi-process environments. Running a container runtime on top ju

Hi, author here, You can, and we've written about the differences also, here [0]. The summary is that there is still a performance hit for boot time (100s of milliseconds to seconds vs. 1 to 100 of milliseconds for Unikraft); performan

In fact gVisor is the opposite, it injects more guard instructions between the application and the kernel across the syscall layer in order to make stronger security guarantees. These additional guards slow the application even further by

In fact this is not true with Linux. We did a study of this[0] and found that there are too many interdependencies between Linux kernel subsystems. The smallest, usable Linux kernel we test with sometimes is around 30MB. In comparison, co

Hi, [disclaimer, I am a project maintainer]. The key difference between unikernels (and library OSes) vs. other kernels is that each kernel is different with a unikernel. Your application goes through a process of specialization, where you

Hi, 1. Yes. We're essentially a baremetal solution. Either we run it on your behalf (this is kraft.cloud), or we deliver an ISO or AMI and this can be installed on-prem/cloud-prem. This latter solution is our enterprise offering.

Definitely! We plan on having a pay-per-millisecond pricing model as well. There's an initial free tier that, but once limits are reached, we will switch to pay-as-you-go plan. Our next offering ("developer") is still work-i

The biggest take away from this is the LAM-over-email which was hidden away in one of the demos. This has a lot more potential (esp. in a business context) in my opinion than the phone itself. Being able to directly email an autonomous age
