Should You Pay for CapMeter When Free Claude Trackers Exist?
Honestly? For a lot of people, no. If all you want is the current percentage in your menu bar, there are perfectly good free tools that do exactly that and nothing more, and paying for a bare percentage would be a bad trade. I'd rather tell you that up front than pretend otherwise.
Where it stops being that simple is once you ask for anything beyond the number itself.
The free field, briefly
Claude Usage Tracker (MIT license, installed via Homebrew, built by hamed-elfayome, over 3,000 GitHub stars) reads the widest set of sources of anything here — your claude.ai session, Claude Code, and the API console — and shows a six-step color-coded pace indicator. No time estimate, no alerts beyond what's on screen, no export.
ClaUse Bar (Mac App Store, free) reads your claude.ai login and switches between multiple organizations. That's the whole feature set: a live percentage, nothing else layered on top.
Claude-God (MIT, on GitHub) is aimed at Claude Code specifically — it logs in via claude login OAuth and reads local session files, with a velocity-based prediction and WidgetKit gauges. Good if you're Claude Code-only; blind to anything you do in a browser.
What none of them do
None of the three send an alert anywhere other than their own screen — no Slack, no Discord, no webhook, so if you're not looking at your Mac when the threshold hits, you don't find out. None keep exportable history beyond what's on screen at that moment. None have a widget that survives switching Spaces or full-screen apps. And only one of the three attempts a time-based prediction at all, and it only covers Claude Code.
So who should actually pay
If you check usage the same way you'd check the time — a glance, then forget it — a free tool is genuinely enough, and I'd tell you to save your money. If you've ever had a session cut off mid-task because you weren't watching closely enough, or you want a threshold to actually reach you instead of hoping you notice, that gap is what CapMeter exists to close. It's not a better version of the same thing; it's built for a different amount of attention than "check it when I remember to."
