OpenTokenUsage is a lightweight Windows system-tray application published by PowerUserZ that centralizes the monitoring of AI coding subscription usage. Its core purpose is to give developers a single, always-accessible place to see how much of their AI coding subscriptions they have consumed, supporting providers such as Claude, Codex, Copilot, Cursor, and Gemini, among others. Rather than requiring users to check each service individually, the application aggregates usage information directly in the Windows system tray, making it well suited to developers who work with multiple AI-assisted coding tools and want to avoid unexpectedly exhausting subscription quotas mid-session. The software is a Windows fork of OpenUsage and extends that project's foundation with full Windows support, ensuring the tracking experience is native to the Windows desktop environment. Architecturally, OpenTokenUsage is built around a plugin-based provider system, which means support for individual AI services is implemented through discrete provider plugins; this design allows the range of tracked services to be expanded beyond the built-in providers and accommodates services beyond the explicitly named ones, as indicated by the "and more" coverage noted in its description. In addition to the tray interface, the application exposes a local HTTP usage API, enabling usage data to be consumed programmatically by other tools, scripts, dashboards, or automation workflows running on the same machine. This combination of a passive tray display and an accessible local API makes the tool relevant to both casual monitoring and more integrated developer tooling setups. Within a software catalog, OpenTokenUsage fits the developer utilities and system monitoring category, specifically targeting usage and quota tracking for AI coding assistants on the Windows platform. The current release is version 0.6.29, and the project has published four versions in total, reflecting an actively iterated, early-stage codebase. As a lightweight utility, it is designed to run unobtrusively in the background while keeping subscription consumption visible at a glance.
