Code Meter
Code Meter

Managing API costs for AI coding tools is a practical concern developers face regularly. When integrating Claude, Codex, Z.ai, or Minimax into your workflow, exceeding your usage limit or hitting rate ceilings can disrupt development or trigger unexpected charges. Code Meter addresses this problem by delivering real-time usage monitoring in the macOS menu bar, giving developers visibility into consumption before issues occur. The product's core value is immediate and simple: install it, authenticate with your chosen provider, and see usage metrics without checking dashboards or guessing remaining capacity. Setup completes in seconds, and the app supports four major AI coding providers, making it relevant across different tool preferences. What distinguishes Code Meter is its privacy architecture. Rather than funneling credentials through intermediary services, the application reads credentials locally from macOS Keychain and communicates directly with each provider's API—Anthropic, OpenAI, Z.ai, or Minimax. Credentials never leave your device. Usage history stores locally via SwiftData, and widget data remains isolated in App Group containers. This design choice appeals to developers concerned about credential exposure, especially in regulated industries or security-sensitive environments. The privacy commitment extends to analytics. Code Meter uses PostHog for anonymous product telemetry—recording only app version, OS version, and feature interactions—hosted on EU Cloud infrastructure with IP capture and device fingerprinting disabled. It represents a transparent approach to usage analytics; the company documents what it collects and explicitly discloses why. The feature set covers essentials: the menu bar widget shows usage at a glance, additional widgets provide supplementary views, and historical charts enable tracking over time. Alerts flag overages before they compound. The product is a free download from the Mac App Store, requiring macOS 26 or later. RevenueCat infrastructure suggests potential premium features, though none are documented currently. Code Meter solves a concrete problem for developers managing multiple AI APIs with a privacy-first architecture that rejects the surveillance model prevalent in developer tools. Its strength lies in restrained functionality delivered without data extraction. Developers get visibility where it matters—their own usage—without surrendering credentials or behavioral data to another platform.
