# Claude Code Session Explorer

A browser-based inspector for Claude Code JSONL session transcripts. Think Chrome DevTools' Network tab, but for understanding what Claude did during a coding session — every tool call, thinking block, context window shift, and subagent spawn laid out on a single interactive timeline.

## Why

Claude Code sessions can run for hundreds of turns across multiple subagents, consuming tokens in ways that are hard to reason about from the raw JSONL. This tool lets you:

- Watch a session live as Claude works — the timeline updates automatically
- See exactly where context tokens are spent and when compactions fire
- Trace tool call chains and inspect their inputs/outputs
- Understand subagent lifecycles — which tool spawned them, what they did
- Spot errors, slow calls, and repeated patterns at a glance
