SpendBar

About

SpendBar is a macOS menu bar application that monitors your spending on Anthropic and OpenAI APIs, helping you avoid unexpected invoices. You can establish a budget and view costs by provider or combined as a single total for all AI services. All data remains on your device: your API keys are stored in the macOS Keychain, your spending information stays on your Mac, and the app requires no account, collects no analytics, and uses no backend server.
