As a fellow user of existing usage monitors for Claude Code, I was looking for something simpler which didn’t require me to change views to look at my usage.
So I built a "simple usage monitor" that displays metrics directly in the last line of your terminal so you can continue using Claude without looking elsewhere.
simple-usage-monitor and Claude Code function independently of each other in the same terminal, so even if the overlay were to crash, your Claude session will remain uninterrupted.
You get: Token counting Cost counting (for supported models, including Opus 4.5) Session reset timer Number of messages sent Plan based limits
Hope someone finds it useful!
