Most Claude Code tools are CLI cost-counters. Claude Session Monitor is different: a native VS Code extension that turns your local session files into a browsable workspace — full transcript, tool calls & sub-agents, per-response token & cost, an analytics dashboard, and a CLAUDE.md memory view. Everything is searchable, resumable, and 100% local-first — nothing leaves your machine. Free; works in VS Code, Cursor & VSCodium.
