Altimeter is an extension for monitoring used/spent tokens in Antigravity IDE, providing simple yet powerful token usage stats. It brings deep observability to the Antigravity Language Server, offering a visual dashboard for monitoring session performance and model-specific usage metrics directly in the IDE.
- Automatic Service Discovery: Should support separate processes on Windows, macOS, and Linux.
- Token Statistics: Clear breakdown of Input, Cache, and Output tokens.
- Statistics Dashboard: Visual horizontal stacked bar charts and daily breakdown tables for long-term usage trends.
- Sidebar: View current session information and usage stats directly in the sidebar.
This project stands on the shoulders of giants and adjacent explorations:
- Tokscale: Inspired by discussions and concepts around token scaling. See Issue #40 for related context.
- Antigravity Cockpit: We examined vscode-antigravity-cockpit to understand an interaction with the Antigravity Language Server.
- Google APIs: Heavily utilized googleapis for robust protocol buffer integration and data structure alignment.
- Gemini CLI & Similar Tools: Inspired by tools like the Gemini CLI which provide token usage transparency, empowering developers to improve their work effectiveness by understanding the cost and weight of their interactions.
Altimeter is available on the Open VSX Registry.
- Open the Extensions view in VS Code (or compatible editor).
