What are the best open-source web browsers?
By GitHub stars, Ladybird is the most popular (66,446 stars), followed by Zen Browser and Nw.js. People often use these instead of Google Chrome, Microsoft Edge and Arc. Each page lists the platforms, license and last commit.
Which of these run on Windows, Mac and Linux?
15 of the 19 open-source web browsers listed here run on Windows, 18 on macOS and 17 on Linux; on a Mac, the most starred is Ladybird. 4 can be installed with a package manager such as Flathub, Homebrew, winget or Chocolatey.
Are these open-source web browsers free?
Yes. All 19 use an open-source license (OSI-approved or FSF-free), so you can use, copy and change them for free.
How are these open-source web browsers chosen?
Apps come from desktop awesome lists (Awesome Linux Software, awesome-mac, awesome-windows, awesome-electron and the media and file sections of awesome-cli-apps), more than 70 GitHub topics such as desktop-app, electron-app, tauri-app, gtk, qt, macos-app, pdf-editor, cad and remote-desktop, and a hand-picked list of flagship apps. An app is listed only if it has a license (one GitHub detects, or one appsgit checked by hand), a README and a commit in the last six months, is not archived or a fork, and has 1000+ GitHub stars (topics), 500+ (awesome lists) or 100+ (hand-picked). It must also be an end-user application with a desktop signal: installers in its releases, install instructions for Windows, macOS or Linux, or a Flathub, Homebrew, winget, Chocolatey, Snap or AUR package. Libraries, frameworks, themes, plugins and servers are left out, and source-available apps are labelled as such.
