Install

macOS

brew install --cask donut

Linux

curl -fsSL https://donutbrowser.com/install.sh | sh

This sets up the package repository and installs Donut Browser via your system package manager. Supports Debian/Ubuntu, Fedora/RHEL, and openSUSE.

Standalone .AppImage files are also available on the releases page.

Troubleshooting AppImage

If the AppImage segfaults on launch, install libfuse2 (sudo apt install libfuse2 / yay -S libfuse2 / sudo dnf install fuse-libs), or bypass FUSE entirely:

APPIMAGE_EXTRACT_AND_RUN=1 ./Donut.Browser_x.x.x_amd64.AppImage

If that gives an EGL display error, try adding WEBKIT_DISABLE_DMABUF_RENDERER=1 or GDK_BACKEND=x11 to the command above. If issues persist, the .deb / .rpm packages are a more reliable alternative.

Windows

Download the installer from the releases page.

Nix

A Nix flake is included for development and running release builds on Linux:

nix run github:zhom/donutbrowser#release-start

Self-Hosting Sync

Donut Browser supports syncing profiles, proxies, and groups across devices via a self-hosted sync server. See the Self-Hosting Guide for Docker-based setup instructions.
