Install ​

Install Flint Browser 1.0.0 on Linux or Windows and open it for the first time.

If you have not installed a snap, a PPA or a .deb before, Installing apps explains each one.

Which package to choose ​

PackageWorks on
SnapAny Linux system with snapd, x86-64 (standard edition only)
PPAUbuntu 24.04, x86-64
.debDebian, Ubuntu and related, x86-64
AppImageMost Linux distributions, x86-64, no installation
.tar.gzMost Linux distributions, x86-64
Windows installerWindows, x64

The direct downloads are on the releases page. Files named flint-browser-* are the standard edition; files named flint-browser-plus-* are Flint Plus. The two editions install side by side, so you can have both.

Snap Store ​

bash
sudo snap install flint-browser

The snap is the standard edition. It runs in a sandbox that can reach your home folder and removable drives.

Ubuntu (PPA) ​

The Dhiva Labs PPA is a package archive that apt keeps up to date for you.

bash
sudo add-apt-repository ppa:dhiva-labs/apps
sudo apt update
sudo apt install flint-browser

For Flint Plus, install flint-browser-plus instead of, or as well as, flint-browser.

Debian and Ubuntu (.deb) ​

  1. Download flint-browser-1.0.0-amd64.deb from the releases page.

  2. Open a terminal in the folder you downloaded it to and run:

    bash
    sudo apt install ./flint-browser-1.0.0-amd64.deb

  3. Open Flint Browser from your application menu, or run flint-browser in a terminal.

AppImage ​

An AppImage is a single file that runs without installation.

  1. Download flint-browser-1.0.0-x86_64.AppImage from the releases page.

  2. Make it executable and run it:

    bash
    chmod +x flint-browser-1.0.0-x86_64.AppImage
./flint-browser-1.0.0-x86_64.AppImage

Tarball (.tar.gz) ​
