What’s Unikraft?
Unikraft GmbH is the company behind the next-generation cloud compute platform based on millisecond semantics, Unikraft Cloud. This is based on the open-source, Linux Foundation Open-Source project Unikraft.
“I've seen things you people wouldn't believe... libsql server running with Unikraft Cloud and cold booting in 30 milliseconds."
Pekka Enberg
CTO of Turso
“Imagine running thousands of pods on K8s with just your app code and required libraries, like Alpine images on steroids.”
Ali Khajeh-Hosseini
Co-Founder of Infracost
“Unikraft has been working on some really cool tech for the next-gen of serverless and now Unikraft Cloud lets anyone use it easily!”
Neil Jagdish Patel
CEO of Axiom
A new era of cloud
Unikraft Cloud makes even the heaviest application feel like a function, all while reducing cloud costs.
Automatically accelerate your cloud app as an extremely efficient, green, and highly secure image without infrastructure headaches such as warm- or over-provisioned instances.
“Looks like the unikernel folks were on to something. Compute platforms are trending towards orchestrating micro virtual machines purpose built for running a single application.”

“I was actually more impressed with unikernels with Unikraft than WASM. (And that is saying a lot if you know how I feel about unikernels).”
Darren Shepherd
Creator of K3s
“This has revolutionised our infrastructure — offering efficiency and scalability at a great price-point. It'll be a game-changer for all devops workflows.”
Ludwig Trotter
CEO at IfGive.app
“We took Go codebase we've been working with from an average of ~4s startup with Docker on GCP to ~30ms on Unikraft Cloud.”
Matthew Anderson
Ex-Director, Equinix Metal Platform Engineering
“The Unikraft folks are doing some incredible engineering!”
Shivansh Vi

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.
The Cloud Engineer's Dilemma (Part 2)
Cold starts, slow autoscale, subpar scale to zero, severe over-provisioning and exploding bills. Must the cloud really be this complex? Part 2 of a two-part series.

Unikernels and Monolithic Kernels Unikraft vs Linux
Tooling and Distribution Unikraft vs. Docker
Performance and Security Unikraft vs. WebAssembly
Discover how Unikraft compares against, and works with existing technologies.
If you're running services using public cloud infrastructure, then you're already massively overspending. Unikraft is on a mission to reduce cloud compute bills and increase performance and security.
Learn more about what makes Unikraft differentFrequently Asked Questions
Dive into the following questions to gain insights into the powerful features that Unikraft offers and how it can elevate your cloud development journey.
What’s a unikernel?
A unikernel is a specialized OS/kernel designed to provide a lightweight, single-purpose execution environment for applications, without any unnecessary components to minimize resource usage and attack surfaces. Learn more.
Aren’t virtual machines heavyweight?
They need not be! Unikraft unikernels are extremely lightweight and are fully- fledged virtual machines, providing strong, hardware-level isolation. VMs are the workhorse of public cloud deployments, and with Unikraft they provide the lightweight characteristics of containers of process (e.g., millisecond cold boot times).
How much smaller are Unikraft images?
The answer depends on the application of course, but with Unikraft we can confident say that most of an image’s size is due to the application itself. For example, an NGINX Unikraft image is under 2MBs in size. Do Unikraft unikernels come with security benefits? Yes, especially stemming from the fact that they have a minimal Trusted Computing Base (TCB), and everything is off by default (services, ports, etc).
