Gastank

Gastank is a tiny menu bar / tray app for tracking AI usage across providers.

The name is a pun on Steve Yegge's Gastown project.

Note

The first release supports Github Copilot. More providers will be added depending on need and how much I decide to care.

CLI Usage

The binary includes a built-in CLI. Log in once via the GUI, then:

It's a bit janky at the moment, but it does its job, if for some arcane reason you need it.

gastank usage                  # fetch Copilot usage (JSON)
gastank usage github-copilot   # explicit provider name
gastank --version              # print version
gastank --help                 # show help
