The missing DevTools for Claude Code — inspect session logs, tool calls, token usage, subagents, and context window in a visual UI. Free, open source.
claude-devtools is a visual debugging application that reads Claude Code's locally saved logs and session transcripts and presents their hidden details. Developers use it to inspect tool inputs and outputs, file activity, token usage, subagents, context consumption, and team coordination. The catalogue entries add commands, hooks, agents, instructions, and settings for the tool.
