ZenML ranks #5 in MLOps & Experiment Tracking AI search.

ZenML is an open-source MLOps framework and managed AI control plane founded in 2021 and headquartered in Munich, Germany. It provides a vendor-agnostic orchestration, versioning, and governance layer that enables data scientists and ML engineers to build portable, production-ready pipelines spanning classical machine learning and generative AI workloads. ZenML's core abstraction—the 'stack'—allows teams to define infrastructure components (orchestrators, artifact stores, experiment trackers, model deployers) independently from pipeline logic, eliminating vendor lock-in. The open-source core is licensed under Apache 2.0, while ZenML Pro adds a managed control plane with enterprise features including RBAC, SSO, audit logs, and environment snapshots. The platform is SOC2 Type II and ISO 27001 certified, claims over 1 million total pipeline runs, and reports users at companies including Airbus, AXA, JetBrains, Brevo, and ADEO Leroy Merlin.
