The millisecond compute layer
The compute layer for sandboxes, AI agents, or any workload. VM-grade isolation. Scale to zero in <10ms. Up to 100K+ instances per server.
Deploy on-prem, BYOC or on dedicated hosts - own the full stack.

01 Why teams switch
Run faster, scale smarter, don't pay for idle
Handle millions of microVMs without breaking a sweat.
Keep the tools you love, with the strong security of VMs
02 Any workload
A sample of all of the use cases that Unikraft Cloud can enable for you
03 Feature packed
Fork a live virtual computer in 10 milliseconds, irrespective of its workload (its children too). Fork DBs, sub-agents, parallel headless browsers to retrieve a webpage faster, parallel debugging or build sessions, or whatever your use case demands.
Turn your [sandbox | headless browser | build | etc] runtime into a template and launch large number of instances from it in 10 milliseconds. The platform allows for 1,000s such templates — full flexibility and power!
Checkpoint your running virtual computer at any point in time, rewind it, or launch a new VM from an existing checkpoint. And yes, you guessed it, in millisecond timescales.
Shift a running virtual computer from one server to another for HA, maintenance, re-load balancing, scaling in, and many other scenarios (e.g., running on spot instances).
Have virtual computers on different servers in a cluster share persistent storage seamlessly.
Big spikes? No problem. Unikraft Cloud is able to launch a fleet of new hosts in < 20 seconds to cope with unexpected large spikes. And to scale that back in when no longer needed.
Under the hood
See how Unikraft delivers 10ms cold starts, 100K+ instances per server, and 99% infra cost cuts.
04 Secure by design
A sample of recent escapes — every one of them crosses a container or runtime boundary. None of them break out of a VM.
05 Manage it, or not
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).
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.
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!
06 Customer Stories
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.
Guillermo Rauch CEO @ Vercel More from our users
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.
Sören Bramer Schmidt CEO @ Prisma 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.
Shuhao Zhang Co-Founder @ Tinyfish 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!
Neil Jagdish Patel CEO @ Axiom 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..
Alex Greaves Co-Founder @ FlutterFlow 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.
Kelsey Hightower Formerly @ Google Imagine running thousands of pods on K8s with just your app code and required libraries, like Alpine images on steroids.'
Ali Khaej-Hosseini Co-Founder @ Infracost I've seen things you people wouldn't believe @libsqlhq server running with Unikraft Cloud and cold booting in 30 milliseconds 🤯💎🚀"
Pekka Enberg CTO @ Turso Unikraft and Unikraft Cloud are messing with my head. It's a step change in cloud performance.
Chris Esplin Podcast Host @ highlight.io You guys are doing cloud rocket science.
Dmitry Kolesnikov Senior Principal Engineer @ Zalando
Hail Unikernels!! The future of Cloud Computing is here with Unikraft 🙌
Riya Bisht Open-Source Contributor 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 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.
Oscar Beaumont Rust Engineer at Spacedrive.app It is a gorgeous way to build lightweight and secure VM images.
Emad Heydari Beni Researcher at Bell Labs If you want both security and lightness... you can actually have it!
Christoph Berger Author AppliedGo 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 @ IfGive We took Go codebases 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 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.
Juan Cruz Viotti CEO @ SourceMeta The Unikraft folks are doing some incredible engineering!
Shivansh Vi CEO @ Loophole Labs My favorite unikernel framework.
Jonathan Beri CEO @ Golioth This is certainly the future of zero-cost amortized compute per user 💯
