Your Cloud, Your Way
Deploy Anywhere
BYOC, on-prem or dedicated host deployments mean you have full access and control of the host. Full customization potential to meet every single one of your needs. Run our platform on bare metal servers but also VMs (e.g., AWS EC2 instances, GCP Compute Engine VM Instances and Azure Virtual Machines).
Kubernetes
Transparently deploy Unikraft as a node in an existing cluster, whether EKS, GKE, AKS or your own. Schedule pods to it — but have them run as strongly-isolated virtual machines that will scale to zero in 10 milliseconds. All of the power of k8s combined with all of the power and features of Unikraft.
Your Own Linux Distribution, Each Time
Unikraft transparently transforms your Dockerfile into a minimalistic, fast and extremely efficient Linux-based image — your own custom distro with all of the power and flexibility of Linux and none of the crud. Couple this with Unikraft's trimmed down Linux kernel and you're off to the races: run any workload, fast!
What Our Users Say
Guillermo Rauch
CEO @ Vercel
When code is generated by AI and deployed automatically, the infrastructure behind it must be radically faster and lighter. That's why Vercel Ventures invested in Unikraft: their cloud infrastructure technology provides exponentially higher efficiency and scalability, along with the strong isolation this new frontier demands.
Neil Jagdish Patel
CEO @ Axiom
Unikraft team has been working on some really cool tech for the next-gen of serverless and now Unikraft Cloud lets anyone use it easily!
Ali Khaej-Hosseini
Co-Founder @ Infracost
Imagine running thousands of pods on K8s with just your app code and required libraries, like Alpine images on steroids.'
Dmitry Kolesnikov
Senior Principal Engineer @ Zalando
You guys are doing cloud rocket science.
Oscar Beaumont
Rust Engineer at Spacedrive.app
This is some seriously impressive tech. I deployed a Rust + Axum API that can cold-start instantly without requiring any wasm specific modifications like Cloudflare Workers.
Ludwig Trotter
CEO @ IfGive
This has revolutionised our infrastructure — offering efficiency and scalability at a great price-point. It’ll be a game-changer for all devops workflows.
Shivansh Vi
CEO @ Loophole Labs
The Unikraft folks are doing some incredible engineering!
Sören Bramer Schmidt
CEO @ Prisma
With Unikraft, we can run over 100,000 strongly isolated PostgreSQL instances on a single machine. That density is unheard of in traditional architectures and fundamentally changes the economics of the game — we’re stepping into a new infrastructure paradigm.
Alex Greaves
Co-Founder @ FlutterFlow
Choosing Unikraft to power our platform was one the best decisions we’ve made. It’s a powerful and reliable service and the support is fantastic..
Pekka Enberg
CTO @ Turso
I've seen things you people wouldn't believe @libsqlhq server running with Unikraft Cloud and cold booting in 30 milliseconds 🤯💎🚀"
Riya Bisht
Open-Source Contributor
Hail Unikernels!! The future of Cloud Computing is here with Unikraft 🙌
Emad Heydari Beni
Researcher at Bell Labs
It is a gorgeous way to build lightweight and secure VM images.
Matthew Anderson
Ex-Director, Equinix Metal Platform Engineering
We took Go codebases we’ve been working with from an average of ~4s startup with Docker on GCP to ~30ms on Unikraft Cloud.
Jonathan Beri
CEO @ Golioth
My favorite unikernel framework.
Shuhao Zhang
Co-Founder @ Tinyfish
With Unikraft, we successfully scaled our enterprise web agent infrastructure to handle increased demand while maintaining the reliability and performance standards our enterprise customers expect. Working with the Unikraft team has been exceptional - their expertise and responsiveness made our deployment smooth and successful.
Kelsey Hightower
Formerly @ Google
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.
Chris Esplin
Podcast Host @ highlight.io
Unikraft and Unikraft Cloud are messing with my head. It's a step change in cloud performance.
Darren Shepherd
Creator of K3s
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).
Christoph Berger
Author AppliedGo
If you want both security and lightness... you can actually have it!
Juan Cruz Viotti
CEO @ SourceMeta
I am very impressed with Unikraft. These people are pioneering a next generation approach to cloud computing that is much faster, secure, and sustainable than anything else I’ve seen in the space. This will be bigger than the Docker revolution from the past decade.
Ikechi Obiajunwa
Founder @ onepod.ai
This is certainly the future of zero-cost amortized compute per user 💯
