What is claude-devtools?
A free, open-source debugging tool for Claude Code. Reads ~/.claude/ logs and reconstructs the full session — file paths, tool calls, thinking, tokens — that the terminal hides.
claude-devtools is a free, open-source Claude Code debugging tool. It reads the Claude Code logs already saved to ~/.claude/ on your machine and reconstructs full session transcripts — every file read, every tool call, every thinking step, every edit, every token consumed — in a structured, searchable interface.
It does not wrap or modify Claude Code in any way. It works with every Claude Code session you've ever run — from the terminal, from an IDE, or from any other tool that uses Claude Code.
The app is distributed as an Electron build for macOS, Windows, and Linux, plus a standalone Docker / Node.js server you can run on a remote machine. There are no API keys, no logins, and no outbound network calls in standalone mode.
