rungraph: Visualize and replay Claude Code runs
Express-Phase1532 · reddit · 2026-08-26
The author built rungraph to address the lack of detailed visualization in Claude Code during long runs.
Features:
- Visual Graph: Reads Claude Code sessions to map prompts, sub-agents, and tool calls into a graph, showing execution flow.
- Deep Inspection: Click nodes for details/thinking; timeline playback to locate retries and errors.
- MCP Integration: Acts as an MCP server, allowing you to ask Claude in the terminal why a specific edit failed, highlighting relevant nodes.
- Collaboration & Security: Export runs for team analysis; warns if secrets are about to leave the machine.
- Local & Compatible: No hooks required; reads existing local sessions (including Cursor, Codex).
