Claude DevTools

First Added:July 6, 2026 Updated: July 7, 2026

Claude DevTools is a local desktop app that reads Claude Code session logs from ~/.claude/ and restores tool calls, thinking steps, and context breakdown the terminal hides. We trial it for post-session debugging, subagent review, and copy-friendly transcript inspection.

Blurb

Your Claude is coding blind.

Summary

When to use:

  • After Claude Code v2.1.20+ collapsed terminal output into opaque summaries
  • Inspecting Read/Edit/Bash I/O and subagent trees
  • Per-turn context attribution (CLAUDE.md, skills, @-mentions, tool output)
  • Cross-session search or SSH remote session review
  • Alerting on sensitive file access or high token use

When to skip: aggregate cost dashboards and quota progress bars (use Claude Usage or CodexBar); sessions with no local JSONL (Cowork); replacing --verbose when you only need a one-off raw dump.

Trade-offs: MIT desktop app (macOS Homebrew cask, Windows .exe, Linux AppImage, Docker self-host). Reads disk only. No login, API keys, or outbound calls. Works on historical sessions from any tool that wrote ~/.claude/ logs.

Repomatt1398/claude-devtools (MIT, TypeScript, ~3.7k stars)
Installbrew install --cask claude-devtools; or GitHub Releases (.dmg, .exe, AppImage); Docker self-host
Data sourceRead-only access to ~/.claude/ session JSONL already on disk
Not a wrapperDoes not hook or modify Claude Code; parses existing logs

Key features:

  • Context reconstruction: per-turn token attribution across seven categories with compaction visualization
  • Tool call inspector: syntax-highlighted reads, inline edit diffs, bash output, nested subagent trees
  • Project memory pane: browse ~/.claude/projects/ memory layers with in-app search and “Open in…” launchers
  • Notification triggers: regex alerts for sensitive paths, tool errors, token thresholds
  • SSH remote sessions: inspect logs on remote hosts via ~/.ssh/config
  • Command palette: Cmd+K cross-session search with snippet highlights
  • Multi-pane layout: compare sessions side by side

Fit: Tool / AI Agent debugging layer for Claude Code. Complements Claude Usage (charts and cost totals) and CodexBar (provider quota windows).
