What are the best open-source password managers and security tools?
By GitHub stars, Clash Verge Rev is the most popular (149,808 stars), followed by Sniffnet and Algo. People often use these instead of 1Password, LastPass and Little Snitch. Each page lists the platforms, license and last commit.
Which of these run on Windows, Mac and Linux?
51 of the 75 open-source password managers and security tools listed here run on Windows, 57 on macOS and 55 on Linux; on a Mac, the most starred is Clash Verge Rev. 21 can be installed with a package manager such as Flathub, Homebrew, winget or Chocolatey.
Are these open-source password managers and security tools free?
74 of the 75 use an open-source license, so they are free to use and change. 1 is source-available (VeraCrypt): the code is public but the license restricts some uses.
How are these open-source password managers and security tools 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.
