CUStats - Track Claude & Codex Usage

The third feature set revolves around multi-account management and cross-platform accessibility. CUStats supports up to ten Claude and OpenAI Codex accounts on macOS and up to five on its mobile counterpart, CUStats Go, with a unified All Accounts Dashboard for a consolidated view. It offers staggered API refreshing to avoid overwhelming service endpoints and provides per-account status badges. Furthermore, the product extends to iOS with CUStats Go, which delivers Home Screen widgets in three sizes that support background auto-refresh, bringing key usage data and pace tracking to your mobile device without needing to open the app.

The product operates through a native application architecture that prioritizes security and user privacy. On macOS, it installs as a standard App Store application with App Sandbox enabled for enhanced security. Authentication is handled by using your existing claude.ai session token or OpenAI Codex login credentials, which are encrypted locally on your device using AES-GCM encryption before any API calls are made. The app periodically polls the respective service APIs to fetch the latest usage data, which is then processed and displayed through its native interface. All data processing and storage occur locally on your device.

Users gain significant benefits and measurable outcomes from using CUStats. The most direct benefit is the elimination of surprise rate limits, which preserves workflow continuity and prevents the loss of valuable context during extended coding or creative sessions. The predictive analytics enable better resource planning, allowing users to pace their AI usage effectively across a week or month. The multi-account dashboard reduces cognitive load by centralizing information, saving time otherwise spent switching between browser tabs and accounts to check individual statuses.

Concrete use cases illustrate its practical value. A freelance developer using both a personal Claude Pro account and a client's Codex subscription can monitor both from a single menu bar icon, receiving a color-coded warning when the client account enters a 'Risky' usage zone. A development team lead can use the All Accounts Dashboard to get a quick overview of usage across the team's shared Claude Max seats to ensure no single project exhausts the shared weekly limit. An iOS user can add a large widget to their home screen to see pace predictions for their primary Claude account, receiving a visual alert for any 2x usage promotions without opening any apps.

The target users are primarily developers, engineers, and technical professionals who integrate Claude and OpenAI Codex into their daily workflows for tasks like coding, debugging, and technical writing. This includes Claude Pro & Max subscribers, OpenAI Codex users, and teams managing multiple AI service accounts. The product integrates directly with the Claude and OpenAI Codex services via their APIs. It is built as a native macOS and iOS application, with an Android version announced as coming soon. Pricing is a one-time purchase model, starting from $9.99 for macOS and from $8.99 for iOS on the App Store, with no subscriptions.

In summary, CUStats delivers essential visibility and control over AI service usage quotas through real-time tracking, intelligent forecasting, and robust multi-account management. Its privacy-first, local-data approach and one-time purchase model make it a reliable and trustworthy tool for any professional dependent on Claude and Codex. By transforming opaque usage limits into clear, actionable insights directly in your menu bar or on your mobile home screen, it ensures you can maintain your creative and productive flow without unexpected interruptions.
