Install

For your user, no sudo, on Linux or a Mac. Run the command again to update.

curl -fsSL https://this-site/install.sh | sh

On Linux it installs the app, its menu entry, and CSV files opening with it; start it from your app menu or with brick. It needs GTK 4, which GNOME desktops have; otherwise the installer says how to get it.

On a Mac with Apple Silicon and macOS 14 or later, it puts Brick in your Applications folder, with everything it needs inside. CSV, TSV, and Excel files list Brick under Open With; to open them with Brick by default, select one in Finder, then File > Get Info > Open with > Change All.

To remove it:

curl -fsSL https://this-site/install.sh | sh -s -- --uninstall

On Windows 10 and 11, 64-bit (a preview): for your user, no admin rights. Paste this into PowerShell; run it again to update.

irm https://this-site/install.ps1 | iex

It puts Brick in your user's Programs folder, with everything it needs inside, and in the Start menu. CSV, TSV, and Excel files list Brick under Open with, and Windows keeps your default apps; to open them with Brick by default, right-click one, then Open with > Choose another app > Brick > Always.

To remove it, use Settings > Apps > Installed apps, or:

& ([scriptblock]::Create((irm https://this-site/install.ps1))) -Uninstall

Downloads

From the DMG: open it and drag Brick to Applications. Brick isn't notarized by Apple yet, so the first time you open it macOS says it can't check it. On macOS 15 or later, open System Settings > Privacy & Security and click Open Anyway beside Brick's name; on macOS 14, Control-click Brick in Applications and choose Open. Or run this once in Terminal:

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

From Setup.exe: Brick isn't signed yet, so when you open it Windows may say “Windows protected your PC”. Click More info, then Run anyway. Setup installs for your user and asks for no admin rights.

The install commands need none of this: what curl and PowerShell download isn't flagged. Check a download against its sha256 with shasum -a 256 on a Mac, sha256sum on Linux, or Get-FileHash in PowerShell.
