3 tools to consider instead of Kubeflow, shown against it.

Kubeflow Metaflow BentoML Seldon
Vendor Kubeflow project (CNCF) Outerbounds; originated at Netflix BentoML, Inc. Seldon Technologies Ltd. (acquired by TrueFoundry, June 2026)

Best for Platform teams that already run Kubernetes and want to orchestrate ML pipelines on their own infrastructure. Data science teams wanting a lightweight Python framework to move pipelines from notebook to production. Teams that need to package and serve trained models as scalable inference APIs. Platform teams deploying and rolling out models on Kubernetes who need built-in canary/A-B routing.
Pricing

Kubeflow is free, open-source software; costs come from the Kubernetes cluster and cloud infrastructure it runs on.

Pricing has not been verified yet — see the vendor's site.

Metaflow the framework is free and open source; scaling costs come from the cloud compute/storage it's configured to use, and Outerbounds' separate managed platform is priced independently.

Pricing has not been verified yet — see the vendor's site.

The BentoML framework is free and open source; BentoCloud is a separate paid, usage-based managed serving platform, but its current published rates could not be confirmed from the vendor's own pricing page in this session.

Pricing has not been verified yet — see the vendor's site.

Seldon ML Server remains open source and free; commercial Seldon Core / Core+ deployments are sold through custom, sales-negotiated contracts with no published self-serve pricing found on the vendor's site.
