The compute platform for all your workloads
A high-performance platform at any scale, built for open data formats and ready for your agents.
Trusted by data and AI teams around the world
Four reasons organizations build with Nanook
Write once, run anywhere
The same Polars code you write locally runs in production, exactly as it is. The scale changes. Your code doesn't.
Scale without complexity
Grow from a single machine to a full cluster exactly when you need to, without taking on a distributed-systems project of your own.
Optimize and profile your queries
Nanook comes with an advanced query profiler and built-in MCP server, allowing you to reason about your query performance and keep optimizing.
Data stays in your environment
Your data stays exactly where it is, inside your own infrastructure. All we ever see is the metadata that powers your dashboard.
Runs in your infrastructure, next to your data
Deploy on AWS, Kubernetes, Ray or bare metal. With your data and compute in the same place, queries are fast and nothing leaves your network.

Deploy entirely in your own infrastructure
The same scalable performance as Nanook in the cloud, with zero external dependencies. Your data stays yours, always.
Integrated with your infrastructure
Polars fits into the stack you already use, from on-premises hardware to your existing cloud, data platforms, and tools.
Air-gapped ready
Nanook is built to run in fully isolated environments, sealed off from the outside entirely.
Meets your compliance standards
Polars is SOC 2 audited, and your data never leaves your environment, so your security and compliance teams stay in control.
Case studies
A cornerstone for advanced analytics at scale
“Polars has become a cornerstone for advanced analytics, delivering exceptional efficiency on even the most complex transformations.”
Built for data teams,
from development to production
Query visibility
Real-time observability into every query and every cluster, so you can always see exactly what's running and why.
Built for agents
Your agents connect over MCP to find any query, see how it ran stage by stage, and suggest how to make it faster.
Extensible
Add your own custom expressions, just as fast and easy to use as the ones we ship.
Fits the infrastructure you already run
Run small jobs on a single node and large ones across a cluster, from one platform that connects to your storage, infrastructure and observability tools.

Frequently asked questions
Polars Nanook is free to start, with 2,000 vCPU-hours a month on Developer. Beyond that, you pay as you go per vCPU-hour, and organizations with large workloads can reach out for a volume discount on Team or custom pricing on Enterprise.
Learn moreYour data stays in your own cloud account or your own infrastructure, always. We only receive the metadata needed to power your dashboard, never your underlying data.
Nanook runs in your infrastructure. Either natively in your AWS cloud (with more clouds on the way), on Kubernetes, Ray or bare metal. Air-gapped deployments are available in our Enterprise tier.
No. The exact same code you write for Open Source runs on Nanook. You're scaling the environment around your query, not rewriting the query itself.
Enterprise Support gives you a direct line to the Polars core team, priority response on critical bugs, and priority consideration on our roadmap.
Yes. Nanook is the new name for Polars Cloud, and Polars On-Premises is now part of it too: one product that runs managed in your own cloud account or on your own infrastructure. Code written for Polars Cloud keeps working on Nanook.
