Release 11 “Metis”: Snapshots, Sandboxes, and a Shield
Branching and checkpointing, persistent custom filesystems, a plugin API, and a network shield that keeps secrets out of your microVMs entirely — plus a completely revamped dashboard. Here is everything in R11.

The Mighty (micro)Virtual Machine: The Only Isolation Primitive That Actually Isolates
A no-BS guide to VMs, containers, microVMs, and isolates — and why, for multi-tenant workloads, there is, and only ever was, one right answer.

Cramming 1M (Scaled to Zero) Virtual Machines in a Single Box
At Unikraft, we're on a quest for exponentially better cloud efficiency. We redesigned our platform to fit over 1 million scaled-to-zero microVMs on a single standard server, with cold starts and resumes still in single-digit milliseconds.

AI Startup? You Need to Think about Scale from Day 1
The era of "move fast, fix infra later" is over for AI companies. It used to be the case that if you were an early stage startup the name of the game would be to get whatever infra would get you started the quickest. That appears to no longer be the case.

We Raised $6M to Build the Future of (AI) Cloud Infrastructure
Today, and after years of hard work, we’re ecstatic to announce the launch of Unikraft Cloud, a radical, new cloud platform based on years of research and providing exponentially better scalability and efficiency (think running millions of strongly isolated instances on a few servers instead of an entire datacenter). In support of this, we’re also super proud to announce our latest $6M seed raise with Heavybit as lead investor, with the participation of Vercel Ventures, Mango Capital, Firestreak Ventures, Fly VC and First Momentum Ventures, along with a host of world class angels.

Running Thousands of Millisecond Headless Browsers on a Single (Cloud) Server
Headless browsers have become a fundamental cog in the AI machine, running as a cloud service for running JavaScript code, scraping websites, automating testing, and integrating with AI agents. A headless browser is, however, a resource-hungry, heavy beast. In this article we show how Unikraft Cloud tech allows for deploying 1000s of these on a single server, while ensuring they can be started in 10s of milliseconds.

SOC2-I Compliance: An Intense but Extremely Valuable Journey
At Unikraft, we recently completed our SOC2 Type 1 audit. What we thought would be a process of improving security turned into a much more valuable journey about company maturity.

The Idle (and Over-provisioned) Cloud
We generally like to think of the cloud handling gazillion requests per second, but a significant part of it is over-provisioned and so idle. In this post we look into the what, how and why what we term "The Idle Cloud" exists, and how to fix it.
