Chromium
Chromium is an open-source web browser project primarily developed by Google and serves as the upstream codebase for the Google Chrome browser. Released under open-source licenses, it is freely available for anyone to obtain, modify, and distribute. Chromium provides core browser capabilities including web page rendering, JavaScript execution, and a multi-process architecture. Numerous third-party browsers—such as Microsoft Edge and Opera—use it as a foundational framework for their own development, making it a central component of the modern browser ecosystem.
Core Facts
Electron is a cross-platform desktop application framework developed by GitHub that bundles the Chromium browser engine and the Node.js runtime together, allowing developers to build desktop applications using web technologies.
Electron is a cross-platform desktop application framework developed by GitHub in 2013, bundling the Chromium browser engine and the Node.js runtime together.
Tauri uses the operating system's native WebView to render the frontend (WKWebView on macOS, WebView2 on Windows, and WebKitGTK on Linux), rather than bundling a complete Chromium browser engine like Electron does.
Timeline (last 90 days)
Gologin Cloud Browser provides AI agents and crawlers with real Chromium browser instances and keeps login states persistent across runs.
Electron wrapper clients run web apps on the Chromium browser engine, at the cost of high memory usage, slow startup, and requiring extra bridging for system-level interactions.
Zen Browser is based on Firefox's Gecko rendering engine, rather than the Chromium used by Arc.
Chromium uses a multi-process architecture, where each tab and extension may become a separate process, and memory usage is usually higher, especially in scenarios with many tabs.
Moli is a browser engine built from scratch rather than a secondary wrapper on top of Chromium.
Cloud browser services such as Browserless and Apify are mostly based on Chromium.
If you rely on certain Chrome extensions, you can prioritize Chromium-based browsers such as Brave or Edge.
New browser entrants usually choose to "differentiate on top of Chromium" rather than build from scratch in-house.
After Arc stops receiving updates, it will no longer synchronize Chromium security fixes, and unpatched vulnerabilities will accumulate, posing real risks.
Chromium-based browsers need to continuously track upstream security fixes, otherwise known vulnerabilities will remain exposed for a long time.
