Pacer 2.0 expands a Claude-only usage monitor into a macOS menu-bar view for Claude Code, Codex, Antigravity and Cursor accounts. Instead of just reporting the allowance already used, it projects whether the current pace will exhaust a session or weekly window before its reset. This is a planning aid for people juggling coding subscriptions, not a way to increase their limits.

  • Interface: Two menu-bar rings show projected usage at reset; click through for an account’s windows and advice. The sampler writes ~/.claude/pacer/status.json every ten minutes for other local tools to read.
  • Setup: On macOS 13+ with Node 18+ and Xcode Command Line Tools, install with brew install dkremsa/tap/pacer, run brew services start pacer, then copy/open Pacer.app as described in the README. It reads existing local provider logins; you need at least one supported subscription.
  • Cost: The source is MIT-licensed and installable from its public repository. It does not replace or pay for any provider subscription.
  • Limitations: macOS only. Gemini CLI and GitHub Copilot readers are explicitly untested; Claude-only model-mix advice does not apply to Codex. The weekly projection assumes the observed pace continues, so changing workloads or taking days off will change the outcome. The author says it reads stored credentials and talks to each provider’s own usage endpoint; review that access before installing.

HN discussion raises a practical enterprise caveat: Copilot organization usage may require admin or billing permissions. This is a summary of the release and repository documentation, not a hands-on test.
