What is ai-usage?
ai-usage is an AI developer tool that monitors how much of your AI-coding quota is left across Claude Code, Codex, and Grok, and forecasts whether you will run out before the next reset. It exists because each tool shows its own limit and none of them warn you before you hit a wall mid-task. ai-usage shows per-model and per-window limits in one place, through a terminal report (the ai-usage command, with a --json flag for scripting and agents) and a Mac menu-bar app that displays a ring indicator and countdown timers for quota status. For teams, it maps every machine against every subscription and shades each by how much it uses, so you can see which machines or bots are draining a shared login, with support for up to 50 machines per team. Since v0.10.0 it also tracks cost: what each subscription costs per month, how much the team actually used over the last four weeks, and utilization history up to 90 days. It is free and open source under the MIT license; the menu-bar app needs macOS 14 or newer. On BestAIFor it fits with the AI developer tools that keep coding agents and their budgets under control.
