Why I Built This
I've been using Claude Code daily for months. Great tool, but I had no visibility:
- No idea how much each session cost until the bill arrived
- Context would fill up without warning
- Couldn't tell if operations were succeeding or failing
So I built Claude Pulse — real-time monitoring for what matters.
