cclogviewer
Claude Code log viewer — converts .jsonl session files into interactive HTML for review
This utility provides a web-based interface for reviewing Claude Code session logs, transforming raw .jsonl files into structured, interactive HTML. Developers can easily visualize conversation flow, tool calls, and token usage from their Claude Code interactions. It offers a convenient way to debug and understand agent behavior outside of the Claude Code environment.
- Hierarchical conversation display with role indicators
- Expandable tool calls and their results
- Nested Task tool conversation visualization
- Token usage tracking for each interaction
- Syntax-highlighted code blocks within logs
