Ship ML pipelines and AI agents with confidence

Yes. Pricing is unified across both workspaces. The ZenML workspace runs ML pipelines (typed step DAGs, training, batch inference). The Kitaru workspace runs durable AI agents (checkpoints, replay, wait/resume). You pick the workspace per project; Pro plans include both. Same $, same support tier, different SDKs and UI.

Yes. Kitaru is open source under Apache 2.0 — same model as ZenML. Self-host the server in your own VPC, point it at S3/GCS/Azure Blob, and run flows on Kubernetes, Vertex, SageMaker, or AzureML. Pro adds distributed execution, dashboard/API/scheduled/webhook triggers, SSO, audit, and a hosted control plane.

We don’t abruptly cut you off. If you occasionally exceed your plan’s limits, we’ll notify you and suggest an upgrade if the pattern continues. For consistent overages, upgrading to the next tier ensures you get the best value.

Yes! ZenML is open source and can be self-hosted on your own infrastructure completely free — that's the Open Source plan. If you need the Pro control plane or support for a self-hosted deployment, the Enterprise plan covers that too. ZenML uses industry-standard encryption for all data in-transit and at rest. The data is stored on AWS regions in Europe, and a strict backup policy is maintained for all client data. ZenML only stores metadata — and no actual data is kept anywhere on our servers. Data and compute stays on the VPC of the customer.

Run Template Triggers automate executions — ZenML pipeline runs and Kitaru flow executions — from events, schedules, webhooks, or the API. Triggers are a Pro feature: they're available on the Scale and Enterprise plans for more complex automation workflows in production.

The Open Source plan gives you complete control but requires you to manage your own infrastructure. The Pro plans — Scale and Enterprise — provide a fully managed control plane with automatic updates, guaranteed uptime, and Pro-only features like run templates, the Model Control Plane, and RBAC. Enterprise adds governance and deployment options like SSO, audit logs, and air-gapped deployment on top.

The Open Source plan includes access to our public Slack channel and community forums. The Scale plan adds priority support with faster response times. Enterprise includes a dedicated account manager, support with SLAs, and implementation assistance.
