Requirements

The extension requires the CodexBar CLI tool installed on your system.

Install CodexBar CLI

It is recommended to install the CLI via Homebrew, which is the official way:

brew install steipete/tap/codexbar

Homebrew exists for Linux (and is a good package manager). For those who don't know, it can be installed with

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install Cookie Importer (only for Codex users)

It is now distributed separately from the extension and no longer requires PyPI. Download it directly from the repo into ~/.local/bin (the extension looks there by default):

mkdir -p ~/.local/bin && curl -fsSL https://raw.githubusercontent.com/InledGroup/codexbar-gnome/main/scripts/codexbar-cookie-importer -o ~/.local/bin/codexbar-cookie-importer && chmod +x ~/.local/bin/codexbar-cookie-importer

It is a dependency-free bash script (uses secret-tool, openssl, sqlite3).

Install helper to Trust the Certificate of the Antigravity Language Server (only for Antigravity users)

This minimal script is invoked by the extension when you click on the trust antigravity cert button and what it does is save the certificate in the system trust store, elevating privileges.
Since it elevates privileges, it would be unreasonable to integrate the elevation logic into the extension (as JustPerfection told me) so it is served as a standalone script that the user must decide to install, thus complying with GJS guidelines. It is now a dependency-free bash script (no PyPI):

mkdir -p ~/.local/bin && curl -fsSL https://raw.githubusercontent.com/InledGroup/codexbar-gnome/main/scripts/codexbar-ssl-helper -o ~/.local/bin/codexbar-ssl-helper && chmod +x ~/.local/bin/codexbar-ssl-helper && codexbar-ssl-helper

Installation

From EGO

You can download it from the official GNOME store. It takes longer to be updated. https://extensions.gnome.org/extension/9841/codexbar/

From Github

1. Clone or fork the repo
2. Run the ./install script
3. • On Wayland:
     • Log out and log in
     • For fast development and iteration: Run dbus-run-session gnome-shell --wayland --devkit. You need to have installed Mutter Devkit
   • On X11: Alt+F2 and type r and press enter.

From Pulsar Store

Coming soon

Configuration

Access the settings through the gear icon in the extension menu or using your extension manager client.

Provider Commands

Each provider must be configured with a command that returns JSON output.

Example for Gemini:

codexbar --provider gemini --source api --format json

The extension will automatically attempt to locate the codexbar binary in common locations such as /home/linuxbrew/.linuxbrew/bin/ if an absolute path is not provided.

Certain vendors have specific fields in Codexbar CLI, whose interpretation may not have been implemented so this is a great opportunity for you to implement support (if you want) and do a PR.

API Keys (e.g. OpenRouter)

Some providers (OpenRouter with --source api) authenticate the CodexBar CLI via an environment variable, e.g. OPENROUTER_API_KEY, instead of a token cached on disk. Setting that variable in ~/.zshrc, ~/.bashrc, or similar is not enough: GNOME Shell is started by your login/display manager, not by an interactive shell, so it never sources your shell's dotfiles, and any command the extension runs (as a child process of GNOME Shell) inherits GNOME Shell's environment, not your terminal's.

To make the variable visible to the extension, add it to your systemd user environment instead:

mkdir -p ~/.config/environment.d
echo 'OPENROUTER_API_KEY=sk-or-v1-...' > ~/.config/environment.d/codexbar.conf
chmod 600 ~/.config/environment.d/codexbar.conf

Then log out and log back in. environment.d files are only read once, when your systemd --user manager starts — if it's still running from before you added the file (e.g. lingering is enabled: loginctl show-user $USER | grep Linger), a normal logout/login won't pick it up. In that case, apply it to the running instance once, then log out/in as usual:

systemctl --user import-environment OPENROUTER_API_KEY

You can confirm GNOME Shell actually has the variable with:

tr '\0' '\n' < /proc/$(pgrep -x gnome-shell)/environ | grep OPENROUTER_API_KEY

Without it, codexbar --provider openrouter --source api still returns valid JSON, but with a top-level error field and no usage.details — so the OpenRouter tab shows only a bare, empty tier instead of the Credits / API key / Spend history breakdown.
