The short version

  • Each has a real cost: MUI escaping the Material Design look takes more theming effort than teams expect; Rook rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.
  • They diverge on capability: MUI covers Large component set, Rook covers Ceph operator.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

MUI

  • Building an admin or internal application quickly with components that already worknot Rook
  • Teams needing accessible complex widgets without building themnot Rook
  • Products where Material Design is an acceptable or desired starting pointnot Rook

Rook

  • An on-premises Kubernetes platform needing block, shared filesystem and S3 storage without buying three productsnot MUI
  • A team that already runs Ceph and wants its lifecycle managed declaratively inside Kubernetesnot MUI
  • A large cluster where three-way replication overhead is unaffordable and erasure coding is requirednot MUI
  • An organisation building a private cloud that cannot use managed cloud storage services for residency reasonsnot MUI

Where each one falls short

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

MUI

  • Escaping the Material Design look takes more theming effort than teams expect
  • Bundle size is significant, and careless imports pull in far more than needed
  • Advanced components such as the full data grid require a paid licence
  • Major version upgrades have historically required real migration work

Rook

  • Rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.
  • There is no vendor and no SLA; the realistic commercial support routes are IBM Red Hat OpenShift Data Foundation or an independent Ceph consultancy, both of which change the cost picture entirely.
  • Ceph is resource hungry, needing substantial memory and dedicated disks per OSD, so the hardware cost of a properly sized cluster is often underestimated.
  • Recovery and rebalancing after a disk or node failure generates heavy background input and output that can degrade application performance for hours, which surprises teams sizing for steady state.
  • Minimum viable clusters require several nodes with several disks each, so it is impractical at small scale and the entry hardware cost exceeds simpler alternatives.

Answered from the vendors’ own pages

MUI: Is MUI free?

The core library is open source and free. Advanced components, including the full-featured data grid, require a paid licence.

Rook: Who supports it in production?

Nobody by default. IBM sells Red Hat OpenShift Data Foundation, which is supported Rook and Ceph, and independent consultancies sell Ceph support. Decide this before deployment.

MUI: Can MUI look non-Material?

Yes, through the theming system, but a substantial departure takes real work. Teams wanting full design control often prefer unstyled primitives instead.

Rook: Does it need Ceph knowledge?

Yes. Rook handles deployment and routine operations, but troubleshooting a degraded cluster is a Ceph skill and there is no way around it.

MUI: Does MUI handle accessibility?

Components follow WAI-ARIA patterns by default, which is a large part of why teams adopt it.

Rook: Can it replace an object storage appliance?

Functionally yes, through the RADOS gateway, but you take on the operations that an appliance vendor would otherwise carry.
