If you juggle more than one AI coding subscription, you have probably lost track of how much quota is left until an agent stalls mid-task. CreditWatcher, a free open-source tool released on June 30, 2026 by developer Aleksei Artemiev, puts the usage limits for OpenAI Codex, Anthropic's Claude Code, and Cursor in one place, read-only and with no telemetry.

What Happened

Artemiev published CreditWatcher v0.1.0 under an MIT license as both a native macOS menu bar app and a Node.js command-line tool. It runs read-only usage checks against each provider's official endpoints, so you can see remaining quota for all three tools without opening three separate dashboards. It does not proxy inference or scrape web interfaces, and it reads credentials from your existing tool installs rather than asking you to paste API keys.

The tracker targets the exact pain point creators hit as Claude Code and its rivals move to metered plans: knowing where you stand before a long agent run burns through your allowance.

Why It Matters

Usage limits have become the defining constraint of agentic coding. Cursor bills against a monthly quota you can inspect on its usage page, while Codex and Claude Code each meter their own way, and none of them show you the others. For anyone running parallel agents across tools, a single glanceable readout is the difference between finishing a build and getting cut off at 80 percent done. We have covered how Anthropic doubled Claude Code limits, but pricing keeps shifting, and a local tracker lets you adapt without waiting for a provider dashboard to catch up.

Key Details

  • Tools tracked: OpenAI Codex, Anthropic Claude Code, and Cursor, in one view.
  • Read-only: direct HTTP calls to official usage endpoints, no scraping, no inference proxying.
  • Privacy: no analytics, crash reporters, or third-party servers; tokens stay on your machine.
  • Refresh: on-demand with a 60-second cooldown so it never hammers provider APIs.
  • Requirements: macOS 14 (Sonoma) or later for the menu bar app; Node.js 18+ for the CLI.
  • License: MIT, free to clone, build, or download prebuilt installers from GitHub Releases.

What to Do Next

If you run two or more AI coding subscriptions, grab the prebuilt macOS installer or clone the repo and build it, then pin the menu bar readout during your next long session. Note that CreditWatcher is unofficial and unsupported by the three providers, so treat it as a convenience layer, not a billing source of truth.
