The short version

  • Each has a real cost: MUI escaping the Material Design look takes more theming effort than teams expect; OpenSearch diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • They diverge on capability: MUI covers Large component set, OpenSearch covers Full-text search.
  • Prices and features above were last checked on 29 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 OpenSearch
  • Teams needing accessible complex widgets without building themnot OpenSearch
  • Products where Material Design is an acceptable or desired starting pointnot OpenSearch

OpenSearch

  • Log and observability storage where an Apache-2.0 licence is a requirementnot MUI
  • Replacing Elasticsearch after the licence change without changing architecturenot MUI
  • Search plus analytics on one cluster rather than two systemsnot 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

OpenSearch

  • Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
  • Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
  • Overkill for plain application search, where a dedicated search engine is far simpler

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.

OpenSearch: Is OpenSearch free?

Yes, Apache 2.0 licensed under the Linux Foundation. Amazon OpenSearch Service is a paid managed option.

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.

OpenSearch: Why does OpenSearch exist?

Elastic moved Elasticsearch off the Apache 2.0 licence in 2021. AWS forked the last Apache-licensed version, and the project now sits under the Linux Foundation.

MUI: Does MUI handle accessibility?

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

OpenSearch: Is OpenSearch compatible with Elasticsearch?

It was at the 7.10 fork point. Both have developed independently since, so compatibility weakens with every release and should be verified for the features you use.
