The short version

  • Only MUI has a free tier, so it costs nothing to try first.
  • Each has a real cost: MUI escaping the Material Design look takes more theming effort than teams expect; OpsLevel opsLevel does not publish prices at all, not even a starting figure, so you cannot size a budget or compare against Backstage's zero licence cost without entering a sales cycle.
  • They diverge on capability: MUI covers Large component set, OpsLevel covers Service catalogue.
  • Prices and features above were last checked on 31 August 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 OpsLevel
  • Teams needing accessible complex widgets without building themnot OpsLevel
  • Products where Material Design is an acceptable or desired starting pointnot OpsLevel

OpsLevel

  • A platform team that needs to prove every production service has a named owner and an on-call rota before an auditnot MUI
  • Driving a fleet-wide migration such as a runtime upgrade across 400 services with a deadline and visible progressnot MUI
  • Giving developers a paved road to create a new service from a template without waiting on the platform teamnot MUI
  • An organisation where an incident took an hour to route because nobody could identify the owning teamnot 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

OpsLevel

  • OpsLevel does not publish prices at all, not even a starting figure, so you cannot size a budget or compare against Backstage's zero licence cost without entering a sales cycle.
  • The Standard plan caps at 50 users, which is below the size at which service ownership becomes a real problem, so most genuine buyers land on Enterprise and its unpublished pricing.
  • Scores are only as honest as the metadata teams maintain; where ownership records go stale the rubric produces confident numbers about a catalogue that no longer reflects reality, and leadership acts on them.
  • It reports on quality rather than producing it, so it can generate friction between platform teams who set the rubric and product teams who see it as a scoreboard imposed on them without extra headcount to fix the findings.
  • As a hosted product it needs read access to source control, cloud accounts and observability tooling, which is a meaningful vendor review in regulated environments; on-premises exists but only on the Enterprise tier.

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.

OpsLevel: How much does OpsLevel cost?

It does not publish pricing. Billing is per developer using the portal, with volume discounts, and a quote requires a sales conversation.

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.

OpsLevel: How does it compare with Backstage?

Backstage has no licence fee but you staff a team to build and run it. OpsLevel is hosted with checks, campaigns and scorecards out of the box, and you pay per developer instead.

MUI: Does MUI handle accessibility?

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

OpsLevel: Does it require writing catalogue YAML by hand?

No. It auto-discovers and enriches entries from connected systems, though teams still curate ownership and metadata.

OpsLevel: Can it run on premises?

Yes, but only on the Enterprise plan.
