CodexBar and OpenLimiter

The widest provider coverage anywhere, and a real scriptable command line tool.

Platform
macOS 14 Sonoma or later for the application, with command line builds for macOS and Linux. Community integrations exist for Waybar, GNOME, KDE Plasma and Cinnamon.
Licence
MIT
Coverage
Its README claims 69 providers, among them Codex, OpenAI, Claude, Cursor, Gemini, Copilot, Grok, AWS Bedrock and LiteLLM.
Source
Both, and opt in. It reuses provider sessions you already have, whether OAuth, a device flow, an API key, a browser cookie or a local file, with on device parsing by default and cookies only when you ask.

What it does

It is a small macOS menu bar application that keeps every AI coding provider's usage window, credits and reset countdown visible without a login step. A companion command line tool ships alongside it.

What it does well

Nothing else here comes close on coverage, and it is the only tool with a genuine scriptable interface: configuration, cost reporting and a serve command, with JSON output and Linux builds, so it runs in continuous integration.

Where OpenLimiter differs

That command line tool is built for configuration, cost reporting and feeding a status bar, not for handing an agent a bounded budget. Nothing in it turns a remaining percentage into advice a coding agent acts on. The visual product is macOS only.

Before you go looking

An unrelated project of the same name exists: a Bash widget for Waybar on Linux. It is a different program by a different author.

How these were checked

These notes were read off each project's own repository, README or store listing in August 2026. Software moves, so check the source before you rely on any of it, and open an issue if something here has gone stale or is simply wrong.
