See everything Claude Code hides from your terminal
Not another Claude Code GUI wrapper. claude-devtools doesn't run or modify Claude Code — it reads the raw session logs already on your machine and reconstructs everything the CLI hides. Every file path Read, every tool called, every diff Applied, every token consumed — structured into a visual timeline with per-turn context attribution, compaction visualization, subagent execution trees, and custom notification triggers. Works with every session you've ever run. Open source, runs locally.
claude-devtools renders isolated execution trees per agent with their own tool traces, token metrics, duration, and cost. Developers can see how sub-agents handed off work and what each one saw.
The tool provides context window breakdown showing what filled the window, when compaction occurred, and what was discarded. Developers can diagnose compaction boundaries and understand why Claude Code forgot information.
The tool renders every message and tool call as real selectable text, eliminating terminal line wraps, ANSI codes, and broken Markdown. One-click copying works consistently across macOS, Linux, and Windows.
claude-devtools offers per-turn token attribution across 7 categories (CLAUDE.md, skills, @-mentions, tool I/O, thinking, team overhead, user text), replacing opaque progress bars with actual numbers. Developers can identify token drains and optimize their setup.
claude-devtools reconstructs full session transcripts from ~/.claude/ logs, showing every file path, tool call, thinking step, and token that Claude Code's terminal hides. Developers can see the complete reasoning and actions taken.
