claude-devtools

claude-devtools is an open-source desktop observability tool designed to provide deep visibility into Claude Code sessions by reconstructing execution activity directly from local session logs. Rather than acting as a wrapper or modifying Claude Code behavior, the application passively reads the logs stored in the user’s environment and rebuilds a structured, searchable timeline of what actually occurred during each session. The tool was created to address the loss of detail in the standard CLI output, which often summarizes actions without exposing the full underlying operations. It surfaces granular information such as file reads, edits, tool calls, token consumption, and subagent activity, enabling developers to understand exactly how the AI interacted with their codebase. Because it runs entirely locally and makes no network calls, it requires no API keys or configuration and works with any previously recorded sessions.
