Tripmeter — AI skill for Claude Code

Tripmeter Usage

A GNOME Shell extension for checking Claude Code and Codex usage from the top panel.

It shows your current limits and resets, plus an estimate of what your token usage would cost at API list prices. Data comes from local session files and stays on your machine.

Features

• Claude Code and Codex limits and reset times
• Weekly forecast: where the limit lands at reset, weighted by which weekdays you actually work
• API-equivalent cost for the past 24 hours, 7 days or 30 days
• Cost by model, skill, subagent and MCP tool
• Prompt-cache savings
• Panel display with limit, cost or icon only

Tripmeter works with either CLI on its own or with both. It supports GNOME Shell 49 and 50.

Install

Download the zip from the [latest release](https://github.com/TheSalaty/tripmeter/releases/latest), then run:

Settings

Open the settings from the gear in the menu or run:

gnome-extensions prefs tripmeter@thesalaty.github.io

You can change the panel display, visible providers, cost window and refresh interval.

Model prices are defined in [`src/lib/pricing.ts`](src/lib/pricing.ts). To override them, create `~/.config/tripmeter/pricing.json`:

{
  "gpt-5.6": { "input": 5, "output": 30 },
  "claude-opus": { "input": 5, "output": 25, "cacheReadFactor": 0.1 }
}

Prices are in USD per million tokens. The longest matching model prefix wins.
