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
