The short version

  • Only Base UI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Base UI nothing is styled, so the first weeks produce a functional but unfinished interface, and a team without design capacity will ship something worse looking than a styled library would have given them free.; Ex Libris Alma pricing is not published for Alma; the site provides no plans or figures and requires contacting a sales representative for a quote
  • They diverge on capability: Base UI covers Unstyled primitives, Ex Libris Alma covers Unified resource management.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Base UI

  • Nothing is styled, so the first weeks produce a functional but unfinished interface, and a team without design capacity will ship something worse looking than a styled library would have given them free.
  • The project is young and its APIs have changed between releases, so upgrades need reading rather than accepting, and version pinning is currently a necessity.
  • Component coverage is narrower than the mature styled libraries, so date pickers, tables and rich inputs will still come from elsewhere or be built.
  • There is no commercial support and no conformance certification to point at, so an organisation that must evidence accessibility still has to commission its own audit.
  • Consolidating the Radix and Material UI unstyled efforts here leaves the earlier libraries with an uncertain maintenance future, which is a live risk for the many applications built on Radix through shadcn/ui.

Answered from the vendors’ own pages

Base UI: Does this replace Radix UI?

It is where much of the same maintenance attention has moved. If you are on Radix, watch its release activity rather than assuming continuity.

Ex Libris Alma: Why doesn't Ex Libris publish Alma pricing online?

Alma uses a custom quote model. The company directs inquiries to sales representatives who tailor pricing based on institutional size, feature requirements, and implementation scope.

Base UI: What does it affect for shadcn/ui users?

shadcn/ui components are built on Radix primitives, so the health of Radix is your dependency question, not a theoretical one.

Ex Libris Alma: Can I try Alma before committing to a purchase?

Yes, Ex Libris offers a Demo Center where you can explore Alma's capabilities in action before formal pricing discussions.

Source
Base UI: Is it ready for production?

For the components it covers, yes, provided you pin versions and read release notes. The range is narrower than mature libraries, so check coverage against your needs first.

Ex Libris Alma: What support services are available separately from Alma licensing?
