The bottom line

The de facto open-source MLOps standard for Kubernetes-based model serving; enterprise tier adds governance, explainability, and SLA support.

What it really isSeldon — open-core MLOps platform for deploying, monitoring, and governing ML models at scale in Kubernetes.
Our takeSeldon is an ML deployment platform: the leading open-source inference server and model-governance stack for production Kubernetes environments.
The open-source MLServer is free, while enterprise licensing runs from approximately $18,000/year. The 'freemium' price-tier label is also misleading given the open-source core.
Why we rate itBattle-tested open core with a large OSS community; enterprise tier adds multi-model drift monitoring and explainability that most MLOps tools charge a premium for.
The catchKubernetes-first architecture imposes a steep setup barrier; enterprise pricing is opaque and requires vendor negotiation with no self-serve path.

Best / not good for

Best for
  • ML engineering teams running Kubernetes-based inference at scale
  • Enterprises needing model governance, audit trails, and explainability
  • Teams building on Kubeflow, Istio, or existing K8s-native stacks
Not good for
  • Non-Kubernetes shops or teams without infrastructure maturity
  • Data analysts or business users needing no-code ML deployment
  • Early-stage teams without dedicated MLOps or DevOps resources
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Slow — Kubernetes cluster setup and ML framework expertise required before the first model deployment.
  2. Scale breakpoint
    Enterprise licence costs tied to model count; complex deployments often require professional services engagements.
  3. Walled garden
    Low — open-source core ensures no vendor lock-in at the inference layer; models are fully portable.
Still a fit?
If none of these block you, start on the free plan.
