CapMeter vs. SessionWatcher
I built CapMeter, so read the rest of this knowing that. I'm not going to pretend SessionWatcher is bad — it isn't. It solves a different problem than CapMeter does, and for a specific setup it's the better $6.99 you'll spend this month.
| What it reads | CapMeter: your Claude.ai / Codex account, browser or CLI, same number either way |
| SessionWatcher: local files each CLI writes to disk — no browser-only usage shows up | |
| Tools covered | CapMeter: Claude and Codex, both read at account level |
| SessionWatcher: many more CLIs (Cursor, Copilot, Gemini and others) — real breadth advantage if you rotate tools | |
| Price | CapMeter: $9.99 once (launch price, regular $14.99), everything included, 14-day trial |
| SessionWatcher: $6.99 for one tool, $14.99 for three, $59 once or $24/yr for everything | |
| Distribution | CapMeter: Mac App Store only |
| SessionWatcher: direct download / Homebrew, not on the App Store | |
| Alerts | CapMeter: Slack, Discord, or any HTTP webhook, plus quiet hours. SessionWatcher: on-screen only, as far as I can find in its own docs |
The question that actually decides it
Do you use Claude or Codex in a browser, at all? If the honest answer is no — everything goes through a terminal — SessionWatcher's local-file approach loses nothing and its per-tool pricing is cheaper for a single CLI. If you split time between a browser tab and a terminal, or use the ChatGPT or Claude web apps directly, a tool that only reads local CLI files is blind to half your usage. That's not a knock on SessionWatcher's engineering, it's just what "local files" can and can't see.
Where SessionWatcher clearly wins
Tool breadth, and content. It tracks more coding CLIs than CapMeter does, and its site runs a genuinely large library of usage guides — if you're comparing five different AI coding tools' rate limits, you'll probably end up reading one of its pages regardless of which app you install.
If you only use Claude and Codex, and you use at least one of them from a browser, CapMeter reads what SessionWatcher can't see. If your workflow is CLI-only across several tools, SessionWatcher's Pro tier is the more complete fit for the money.
