Chromium (web browser)
free and open-source cross-platform web browser
Chromium is a free and open-source web browser project, primarily developed and maintained by Google. It is a widely used codebase, providing the vast majority of code for Google Chrome and many other browsers, including Microsoft Edge, Samsung Browser, and Opera. The code is also used by several app frameworks.
Licensing
Chromium is a free and open-source software project. Owing to its origins in the WebKit project, Chromium incorporates code subject to a variety of licenses, including LGPL, MIT, Ms-PL, and MPL (with the MPL/GPL/LGPL tri-license clause). Original Google-authored portions and some portions written by Apple are shared under the 3-clause BSD license.
This licensing permits any party to build the codebase and share the resulting browser executable with the Chromium name and logo. Thus many Linux distributions do this, as well as FreeBSD and OpenBSD. Chromium also forms the basis of Electron, which in turn is used for many commercial and proprietary cross-platform applications, such as Slack.
Many Chromium-based browsers, such as Google Chrome and Microsoft Edge, include the proprietary components, such as proprietary wrapper libraries for hardware acceleration.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Chromium (web browser)”, the useful work is to connect “free and open-source cross-platform web browser” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q48524. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
