Installing it, and the one question it asks

  1. Open the disk image and drag Tessera into Applications.
  2. Open it from Applications. macOS says it cannot verify the app, because the build is not signed with a paid Apple certificate. Press Done.
  3. Open System Settings, then Privacy & Security, scroll to Security and press Open Anyway beside Tessera.
  4. Press Open in the last dialog. Only the first time: after that it opens like any other app.

Or skip the clicking, in one line

xattr -dr com.apple.quarantine /Applications/Tessera.app

Run it once, after dragging Tessera into Applications, and it opens normally from then on. It does nothing and says nothing if the flag has already gone.

Homebrew

brew tap ahmmedrejowan/tessera
brew install --cask tessera

Homebrew 7 asks before it loads anything from a tap that is not its own. If it does, run brew trust --cask ahmmedrejowan/tessera/tessera and install again.

Or build it yourself

git clone https://github.com/ahmmedrejowan/tessera.git
cd tessera
npm install
npm run dist

Needs Node 24 or newer, git, and Xcode command line tools (xcode-select --install). Gives you a .dmg and a .zip for Apple Silicon and Intel, in release/, signed ad hoc. Build on the system you want the files for: none of them can be made from another.

Installing it, and the one question it asks

  1. Run the installer. It installs for you alone, so no administrator password is asked for.
  2. Windows says it protected your PC, for the same reason: the build is not signed with a Windows certificate. Choose More info.
  3. Press Run anyway. Only the first time.

Or skip the clicking, in one line

Unblock-File .\Tessera-win-x64.exe

In PowerShell, before running the installer. SmartScreen usually reacts to that mark, so the prompt does not appear; a publisher it has never heard of can still be questioned, and More info then Run anyway always works.

winget

winget install Rejowan.Tessera

Chocolatey

choco install tessera

Scoop

scoop bucket add tessera https://github.com/ahmmedrejowan/scoop-tessera
scoop install tessera

Or build it yourself

git clone https://github.com/ahmmedrejowan/tessera.git
cd tessera
npm install
npm run dist

Needs Node 24 or newer and git. Nothing else: there is no native code to compile. Gives you an installer and a portable .zip, for x64 and Arm, in release\. Build on the system you want the files for: none of them can be made from another.

Installing it

  1. For the AppImage, make it runnable with chmod +x and start it. Nothing else is installed.
  2. For the .deb or .rpm, install the package with your usual tool. Tessera appears in your applications menu.
  3. Nothing asks you to allow anything: Linux has no equivalent of the macOS and Windows warnings.

AppImage

chmod +x Tessera-1.0.1-linux-x86_64.AppImage
./Tessera-1.0.1-linux-x86_64.AppImage

Debian, Ubuntu, Mint

sudo apt install ./Tessera-1.0.1-linux-amd64.deb

Fedora, openSUSE, RHEL

sudo dnf install ./Tessera-1.0.1-linux-x86_64.rpm

Arch, Manjaro

yay -S tessera-bin

Not yet: a PKGBUILD is written on every release but nothing is published to the AUR. Until then, take the AppImage.

Or build it yourself

git clone https://github.com/ahmmedrejowan/tessera.git
cd tessera
npm install
npm run dist

Needs Node 24 or newer and git. For the .rpm on a Debian-like system, also rpm. Gives you an .AppImage, a .deb and an .rpm, in release/. Build on the system you want the files for: none of them can be made from another.
