Local visual DevTools for Claude Code: inspect tool calls, token attribution, context and subagents from session logs.
What is claude-devtools?
A visual desktop and web app that reads Claude Code session logs and reconstructs hidden activity: tool calls, file operations with diffs, per-turn token attribution, context-window composition, extended-thinking content and subagent execution trees. It is read-only, does not wrap or modify Claude Code, and runs fully local with no API keys or outbound calls.
Pros & Cons
Pros
- Solves a real, current pain: recent Claude Code versions replaced detailed output with opaque summaries
- Fully local, no keys, login or network calls, a low trust barrier
- Broad packaging (Homebrew, native installers, Docker) lowers install friction
Cons
- A read-only log inspector, not a workflow tool; value depends on already using Claude Code heavily
- Tightly coupled to Claude Code's evolving internal log format, so it can break as that changes
- Pre-1.0 (v0.5.0), feature set and UX still maturing

When it is interesting
Heavy Claude Code users who want to audit token spend, context usage and subagent behaviour that the terminal hides.
When it is too early
If you use Claude Code only lightly, or want active control rather than passive inspection.

RTK
rtk-ai
CLI proxy that compresses shell command output before your AI coding assistant sees it, cutting tokens 60-90%.
TOON
toon-format
Token-Oriented Object Notation - a compact serialization format that uses ~40% fewer tokens than JSON.
