Material UI
Material UI is a comprehensive library of React components that features our independent implementation of Google's Material Design system. It's trusted by some of the world's greatest product teams because it's been rigorously battle-tested through more than a decade of development by thousands of open-source contributors.
Material UI's core functionality is extended by MUI X, a suite of complex components for advanced use cases.

Quick facts
npm install @mui/materialThis package powers Material UI
The @mui/material package is the canonical implementation of Material UI. Sourcemap Explorer uses this exact npm package as the framework-level fingerprint when it flags Material UI on a page — both via the bundled node_modules/@mui/material/ source paths and via the embedded package.json inside the JavaScript sourcemap.
Common pairings
Packages this one expects to find in the same project. Each is also a Sourcemap Explorer detection target.
How Sourcemap Explorer detects @mui/material
We catch @mui/material from two complementary signals: bundled source paths and the embedded package.json. Modern bundlers (webpack, Vite, esbuild, Rollup, Turbopack) preserve the original node_modules/@mui/material/ paths inside the JavaScript sourcemap's sources[] array — that's the canonical signal. When the matching package.json is also captured in sourcesContent[], we read the exact version field — patch number included. No regex guessing, no version inference.
- 1
Confirm the site exposes sourcemaps
In DevTools Network, check the response headers of any application script for `SourceMap` or `X-SourceMap`. Failing that, fetch the script's last 4 KB and look for a `//# sourceMappingURL=` comment.
- 2
Find the package in the bundle
Open DevTools → Network → reload. Click any application script and look at its sourcemap. Inside, search `sources[]` for entries matching `node_modules/@mui/material/` — every match confirms the package is bundled. The matching `sourcesContent[i]` for `node_modules/@mui/material/package.json` gives you the exact installed version.
- 3
Read the version directly from package.json
Run `jq -r '. as $m | $m.sources | to_entries[] | select(.value | endswith("node_modules/@mui/material/package.json")) | $m.sourcesContent[.key] | fromjson | .version' bundle.js.map`. Sourcemap Explorer automates the same query in the popup.

FAQ
What is @mui/material used for?
Material UI is an open-source React component library that implements Google's Material Design. It's comprehensive and can be used in production out of the box.
How can I tell if a website is using @mui/material?
Open the page in Chrome with the Sourcemap Explorer extension installed and read the Stack tab. We catch `@mui/material` from two complementary signals: `node_modules/@mui/material/` paths inside the JavaScript sourcemap, and the embedded `package.json` we read for exact-version detection. Without the extension you can do the same lookup manually in DevTools — the steps are listed in the "How Sourcemap Explorer detects" section above.
What is the latest version of @mui/material?
9.0.1, as published on the npm registry. The "Recent versions" table on this page lists the most recent 8 releases with their release dates. Sourcemap Explorer reports the version actually bundled into a site, which can lag the latest release by months on real-world deployments.
What is the relationship between @mui/material and Material UI?
@mui/material is the canonical npm package for Material UI. Sourcemap Explorer treats finding `@mui/material` in a bundle as the framework-level signal that Material UI is on the page, and the page you're reading is the canonical Sourcemap Explorer entry for the package itself.

Detected by Sourcemap Explorer
When a bundle ships sourcemaps, we read the embedded package.json for @mui/material and report the precise version. Without sourcemaps, an import / require in the page's scripts is enough to flag it.
