A free, open-source Electron desktop app that acts as missing DevTools for Claude Code, reading local ~/.claude/ session logs to reconstruct full transcripts. It visualizes tool calls, thinking steps, token usage, subagent activity, and context window compaction in a searchable UI.

Use cases

• debug claude code sessions
• view claude code token usage
• inspect claude code tool calls
• understand context window compaction
• read claude code session transcripts
• debug claude code subagents
• find out why claude forgot context
• reduce claude code token costs

When to choose

• you use Claude Code and want visibility into what it actually did
• the terminal's opaque summaries hide tool I/O, thinking, or token attribution you need
• you want to diagnose context compaction or why Claude forgot something
• you need cross-session search and export of Claude Code transcripts without API keys

When to avoid

• you don't use Claude Code or Anthropic tooling
• you need a general-purpose LLM observability platform for production apps rather than local Claude Code session debugging
• you need a CLI-only or headless tool — this is a visual desktop app
