The Problem

Ever run a complex task in Claude Code and wonder:

• "Why is my context suddenly at 95%?"
• "Did that tool call fail, or is it still running?"

Claude Pulse gives you complete visibility into your AI coding sessions.

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.
