Claude Code Karma: Local Observability Dashboard for Claude Code Sessions
What Claude Code Karma Does
Claude Code Karma is a local observability dashboard built specifically for monitoring Claude Code sessions. The tool parses the JSONL files stored in ~/.claude/ and provides a web-based interface for analyzing how Claude Code interacts with custom MCP tools.
Key Features
- Visualizes Claude Code session data through a local web UI
- Provides visibility into plugin usage patterns
- Shows full session timelines including subagents, skills, and tool calls
- Tracks tool, agent, and skills usage across multiple sessions
- Catches silent failures in custom tools
- Allows searching old sessions by prompt, name, or project
- Includes live session tracking via hooks
- Supports tracking across multiple projects and repositories
Technical Stack and Setup
The dashboard is built with FastAPI, Svelte-Kit 2, Svelte 5, and SQLite. All data stays local, and setup takes under 2 minutes according to the developers.
Unexpected Benefits
The developers reported several unexpected benefits from using the dashboard:
- They stopped needing to scan terminal outputs manually
- Gained understanding of their plugin/skills usage patterns, which helped them engineer context better
- Improved prompting skills by reviewing old session timelines
- Caught custom tools failing silently across dozens of sessions
Current Limitations and Call for Contributions
The project has basic cost estimation based on token consumption, but the developers note that "the math is wrong." The per-session and per-project cost numbers in the analytics are currently unreliable. The developers are seeking help from anyone who understands Anthropic's pricing model or has experience with token cost calculation to fix the analytics. Specifically, session-level and project-level cost breakdowns and overall cost analysis are inaccurate.
