The short version

  • Only Seldon has a free tier, so it costs nothing to try first.
  • Each has a real cost: Manus specific pricing and plan tiers not published on accessible pages; users must visit pricing page or contact sales; Seldon seldon Core v2 is under the Business Source Licence rather than Apache 2.0, so production use requires a commercial agreement, and a team that evaluated it believing it was open source discovers the licence is the blocker exactly when the project is ready to ship.
  • Prices and features above were last checked on 30 August 2026.

Seldon

  • Running genuine production experiments where a share of live traffic goes to a candidate model and the results are comparednot Manus
  • Regulated environments needing explanations and drift monitoring attached to the served model rather than bolted on laternot Manus
  • Organisations with an established Kubernetes platform team who want serving expressed as manifests under existing deployment controlsnot Manus

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Manus

  • Specific pricing and plan tiers not published on accessible pages; users must visit pricing page or contact sales
  • Organisational transition mid-2026; unclear how this affects feature stability or pricing continuity
  • No clear free tier mentioned; access requires subscription from apparent launch
  • Limited public documentation on capabilities and limitations

Seldon

  • Seldon Core v2 is under the Business Source Licence rather than Apache 2.0, so production use requires a commercial agreement, and a team that evaluated it believing it was open source discovers the licence is the blocker exactly when the project is ready to ship.
  • Core v1 remains Apache 2.0 but is in maintenance, so taking the free route means running software that receives no new development while the architecture it belongs to moves on without it.
  • Version 2 is a different system rather than a newer release, with different custom resources, a scheduler component and a Kafka-based pipeline model, so migrating from v1 is a re-implementation of every deployment manifest rather than an upgrade.
  • Kafka is a dependency for v2 pipelines, so an organisation that does not already operate it takes on a distributed log with its own storage, retention, rebalancing and failure modes purely in order to serve models.
  • Everything assumes Kubernetes fluency and the failure modes are Kubernetes failure modes, custom resource version mismatches, an operator that will not reconcile, admission webhooks and resource limits terminating an inference pod mid-request, so it needs a platform engineer rather than a data scientist.

Answered from the vendors’ own pages

Manus: Where can I find Manus pricing information?

The Manus pricing page at manus.im/pricing mentions 'Manus Pricing Plans' with the tagline 'Less structure, more intelligence,' but specific pricing details and tier information are not published online. Contact Manus directly to discuss pricing options.

Source
Seldon: Is Seldon open source?

Partly, and this is the thing to check before you build on it. Core v1 is Apache 2.0 but in maintenance. Core v2 was moved to the Business Source Licence in 2024, which allows evaluation but not unlicensed production use. Verify the current licence of each component you intend to run, including MLServer and the Alibi libraries.

Manus: Does Manus offer a team plan option?

Manus mentions a team plan option on its pricing page, but specific details about team size limits, per-seat costs, and features are not published. Interested customers should contact Manus sales to discuss team pricing.

Source
Seldon: What is the difference between v1 and v2?

Architecture, not just version number. v2 introduces a scheduler, a different set of custom resources and Kafka-backed pipelines. Manifests, mental model and operations all change, so treat a move as a project.

Manus: What features are available in Manus?

Manus offers AI design, slides, image generation, music generation, browser operator, and other creative automation features. Specific feature availability by pricing tier requires contacting Manus directly for custom pricing information.

Source
Seldon: Do I need Kubernetes?

Yes. It is a Kubernetes-native system and there is no meaningful deployment without a cluster and someone competent to run it.

Seldon: What is MLServer?

Seldon's Python inference server implementing the Open Inference Protocol, usable inside Seldon deployments or on its own. Check its current licence alongside Core's, since the company has moved projects onto the Business Source Licence.

Seldon: Do I have to run Kafka?

For v2 pipelines, yes. If you only need single models served, that dependency is a large amount of infrastructure for the benefit, and a simpler serving layer may be the better answer.
