Why Google’s Chromium Initiative Could Reshape the Browser Landscape

Google is awaiting a government decision on whether it must divest its Chrome browser as an antitrust remedy, and has jointly announced with the Linux Foundation a plan to support the open‑source Chromium project that underlies Chrome.

The initiative, called “Supporters of Chromium‑based Browsers,” aims to cultivate a sustainable open‑source contribution environment, financially back developers, and encourage broad support and ongoing technical progress for Chromium.

Linux Foundation Executive Director Jim Zemlin said the Browser Foundation Support Group will provide urgently needed funding and development assistance for open development within the Chromium ecosystem, though he did not disclose the source or amount of the funds.

The Linux Foundation receives at least $500,000 annually from Google as a platinum membership fee.

Google contributed over 100,000 code submissions to the Chromium codebase last year, accounting for 94% of total contributions, and hopes other organizations building browsers on Chromium will increase their contributions.

Since Microsoft announced a Chromium‑based Edge in 2018, the Chromium project has become the de‑facto standard foundation for web browsers.

Chrome (Chromium plus proprietary features) holds roughly 68% of the global browser market; when combined with other Chromium‑based browsers such as Brave, Edge, Opera, and Vivaldi, the share is even larger.

The popularity of Chromium demonstrates the cost and technical challenges of competing with Google‑funded engineering teams, aids web standardisation, but may also displace alternative technologies as more organisations join the ecosystem.

There are three major actively supported browser engines: Google’s Blink, Apple’s WebKit, and Mozilla’s Gecko, plus niche projects like Goanna and Servo. These engines handle page parsing, rendering, and include JavaScript engines such as V8 (Blink), JavaScriptCore (WebKit), and SpiderMonkey (Gecko).

Apple’s Safari, built on WebKit, commands about 17% of the global market thanks to platform preferences and default settings that require all iOS browsers to use WebKit.

Without Apple’s distribution advantage, Safari’s market position remains uncertain.

Mozilla’s Firefox, using the Gecko engine, holds only about 2.47% of the market as of December 2024, a decline driven by the growth of the Chromium ecosystem.

Supporters of Chromium‑based browsers could benefit developers dedicated to the Chromium world.

Microsoft Edge Vice President Meghan Perez said Microsoft is pleased to join the effort, which will foster collaboration within the Chromium ecosystem.

Vivaldi CEO Jon von Tetzchner expressed support and indicated interest in signing on.

Nevertheless, an expanding Chromium ecosystem may reduce browser diversity.

As web developer Rachel Nabors observed in 2018, “Chrome has the most resources and leads web development, leaving us unsure whether the web we build is the one we want or the one Google wants.”

The Supporters of Chromium‑Based Browsers will adopt an open‑governance model, prioritising transparency, inclusivity, and community‑driven development, and will establish a Technical Advisory Committee (TAC) to guide the project.

The fund will be managed by the Linux Foundation, while the Chromium project will continue under its existing governance structure.

Meta, Microsoft, and Opera are among the first signatories, committing key funding and development support for open‑source projects related to Chromium‑based browsers.
