The short version

  • 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.; Koha no pricing published; Koha is free and open source with no commercial licensing fee
  • They diverge on capability: Base UI covers Unstyled primitives, Koha covers Circulation 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.

Koha: How much does Koha cost?

Koha is free and open source. There is no software licensing fee. Development is sponsored by libraries, volunteers, and support companies worldwide.

Source
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.

Koha: Are there paid support options available?

While no specific pricing is detailed on the main site, Koha mentions paid support options available from support companies, but exact costs require contacting providers directly.

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.
