Show HN: Pacer – will your AI coding subscription last until the reset?

Pacer is a macOS menu bar tool that monitors whether your AI coding subscriptions (Claude, Cursor, Codex, etc.) will last until their reset period by displaying usage speed rather than just percentages. It tracks multiple accounts simultaneously, provides personalized advice on which models to reduce or switch between based on your actual usage patterns, and sends notifications when usage pace approaches or exceeds 100% of your limit. The tool analyzes your local API transcripts to calculate per-model weight costs, since subscription providers don't publish these details publicly.
