Chromium
Open source browser that Google Chrome is built on. BSD license. Base for Chrome, Edge, Brave, Opera, Vivaldi, Arc — so practically all browser development.
Open-sourced 2008 alongside Chrome. Components: Blink (rendering, forked from WebKit 2013), V8 (JavaScript), Skia (graphics). Microsoft switched Edge to Chromium in 2020. Adoption has created a browser monoculture — critics worry about Google's power over web standards. Cromite, Bromite are de-Googled forks. The Manifest V3 debate (2024) drove many to Firefox to keep blocking ad-blockers.
