Claude Code Karma

Your Claude Code sessions deserve more than a terminal.
A local-first, open-source dashboard that turns your ~/.claude/ data into a visual story — sessions, timelines, costs, and live activity, all on your machine.

Why Claude Code Karma?

If you use Claude Code, you already have a goldmine of data sitting in ~/.claude/ — every session, every tool call, every token. But it's all buried in JSONL files you'll never read.

Warning: Claude Code only keeps session data for about 30 days. Older JSONL files in ~/.claude/projects/ are automatically cleaned up. Since Karma reads directly from those files, deleted sessions will disappear from the dashboard too.

Claude Code Karma reads that local data and gives you a proper dashboard. No cloud. No accounts. No telemetry. Just your data, on your machine.

It works with both Claude Code CLI and Claude Desktop (Claude Code mode) sessions — any session that writes to ~/.claude/ shows up automatically.

Features

Session Browser

Browse all your Claude Code sessions in one place. Search by title, prompt, or slug. Filter by project. See live sessions at the top with real-time status badges — and a >_ button that raises the terminal window a live session is running in.

Session Timeline & Overview

Dive into any session to see exactly what happened — every prompt, tool call, thinking block, and response laid out chronologically. The overview tab shows key stats like message count, duration, model used, and which tools were called.

Session Detail Tabs

Each session page has dedicated tabs that break down different aspects of what happened during the session.

Tasks — See all tasks Claude created and completed during the session, displayed in a flow view with status tracking.

Files — Every file operation in a sortable table — reads, writes, edits — with timestamps, actors, and the tools that made each change.

Subagents — Agents spawned during the session, grouped by type. Expand each to see message counts, tool calls, and what they were asked to do.

Skills — Skills invoked via /skill commands during the session, with their source plugin and invocation count.

Shells — Long-running background shells spawned during the session, with live status, the command each one ran, and runtime.

Analytics — Per-session cost breakdown, token usage, cache hit rates, tool distribution with a donut chart, and a ranked list of every tool used.

Projects

See all your Claude Code workspaces organized by git repository. Each project card shows session count and when it was last active. Expand git repos to see individual project directories inside them.

Analytics

Track your token usage, costs, velocity trends, cache hit rates, and coding rhythm across all projects. See which models you use most and how your usage patterns change over time.

Tools & MCP

See every tool Claude Code uses — built-in ones like Read, Edit, and Bash, plus any MCP integrations you've added (the MCP page in the nav). Grouped by server with call counts and session coverage. Switch to the Usage Analytics tab for activity trends and top tools over time.

Click into any tool for detailed stats — total calls, session count, main vs subagent split, usage trend over time, and a full session history.

Agents

Browse all your agents — built-in, custom, and plugin-provided. See total runs, token consumption, and filter by category to understand how your agent ecosystem is being used. The Usage Analytics view shows activity trends and your most-used agents.

Drill into any agent for run counts, token usage, average duration, usage trends, project breakdown, and a session history showing every time that agent was used.

Hooks

Visualize all your Claude Code hooks organized by lifecycle phase — session start/end, tool use, agent lifecycle, and permissions. See which hooks can block execution and how many registrations each event has.

Plugins

View all installed Claude Code plugins with their agents, skills, and commands. Filter between official and community plugins. See version info and when each was last updated.

Click into any plugin to see everything it provides — agents, skills, commands, MCP tools, and hooks — along with usage analytics showing activity trends and top-used components.

Skills

Track which skills are invoked across sessions, grouped by plugin or shown individually. Click into any skill for usage stats, context split (main vs subagent), and a full session history showing every time that skill was used.

Ticket Linking (Linear / Jira / GitHub Issues)

Attach your Claude Code sessions to the tickets they were about. Karma stays read-only — it stores the link and caches the title/status, but never writes back to your ticket provider.

Three ways to link:

• Paste a URL or key into the Tickets section on any session page
• Type /link-ticket-to-session ABC-123 (or ask the agent in natural language) in any Claude Code session — uses your Linear / Atlassian / GitHub MCP server to fetch the title
• Auto-detect from your branch name — opt-in SessionStart hook that watches for keys like feat/LINEAR-123-foo and links silently in the background

Then browse:

• A /tickets index showing every ticket touched, filterable by provider and project
• A ticket detail page listing every session linked to a given ticket
• A Tickets tab on every project page that aggregates across all checkouts of the same git repo — so a ticket linked from claude-karma/frontend/ also shows on the main claude-karma project

Tickets Index — All linked tickets in a filterable table. Switch between All, Issues, and PRs on GitHub.

Filter by Provider — GitHub shows sub-pill filtering ([All N] [Issues N] [PRs N]) to toggle between categories.

Ticket Detail — View a ticket with all linked sessions. Cross-project rollup shows "N sessions · M projects" with tabs per project.

Project Tickets Tab — Every project page has a Tickets tab that aggregates across all git identity checkouts, so the same ticket appears even if linked from different branch directories.

And More

• Tickets across providers — Link sessions to Linear, Jira, and GitHub Issues in a unified interface
• Plans Browser — View implementation plans and their execution status
• Command Palette — Quick navigation with Ctrl+K / Cmd+K
• Full-text Search — Search across session titles, prompts, and slugs
• Live Sessions — Real-time monitoring via Claude Code hooks
• Open Terminal — One click brings the terminal running a live session to the front (exact tab for macOS Terminal/iTerm2, exact pane in tmux)

Quick Start

# Clone the repository
git clone https://github.com/JayantDevkar/claude-code-karma.git
cd claude-code-karma

# Start API (Terminal 1)
cd api
pip install -e ".[dev]" && pip install -r requirements.txt
uvicorn main:app --reload --port 8020

# Start Frontend (Terminal 2)
cd frontend
npm install && npm run dev

Open http://localhost:5180 to view the dashboard.

This only gets you the historical dashboard. Karma's core feature — live session tracking as sessions actually run — needs one more step, Tier 2 in SETUP.md. Install through Tier 2 by default; the rest of SETUP.md's tiers are optional polish on top.

Desktop App (macOS & Windows)

Two terminals every time gets old. Install a desktop icon that starts both servers for you and opens the dashboard:

python3 scripts/install_karma_app.py           # macOS: /Applications/Karma.app
                                               # Windows: a Desktop shortcut
python3 scripts/install_karma_app.py --dock    # macOS: also pin it to the Dock
python3 scripts/install_karma_app.py --uninstall

Click the icon and Karma starts whichever servers aren't already running, then opens the dashboard. The first launch after a reboot has to compile the frontend (a minute or two), so it posts a "Starting Karma…" desktop notification straight away — the click never looks like it did nothing — and opens the dashboard once the servers answer.

Nothing is hardcoded: the installer works out your repo location from its own path and finds a Python interpreter on the machine, so a clone anywhere works.

Optional: start at login. Toggle it in Settings → Desktop App, or:

python3 scripts/install_karma_app.py --autostart      # on
python3 scripts/install_karma_app.py --no-autostart   # off

This adds a launchd agent (macOS) or a Startup-folder entry (Windows) so the servers are already up when you log in — the dashboard is simply always there, with no icon to click first. It costs roughly 150–350 MB of memory and almost no CPU while idle.

It's also what makes a browser-installed Karma work on its own: a PWA is only a window and cannot start servers, so with autostart you never need the launcher icon at all.

macOS notifies you that a background item was added and lists it under System Settings → General → Login Items; Windows shows it in Task Manager → Startup. You can disable it there at any time. Note that the dashboard's toggle reflects whether the login item is installed, not whether the OS currently has it enabled — if you switch it off in Login Items / Task Manager, the shortcut stays on disk and the toggle still reads on. Use those system settings, or the Remove button, to be sure.

Windows notes. SmartScreen may warn the first time, and Windows will show a firewall prompt when the servers first bind their ports — allow it for private networks. The shortcut runs via pythonw.exe, so no console window flashes.

How It Works

Claude Code already saves everything locally — sessions, tool calls, token counts — as JSONL files in ~/.claude/. Claude Code Karma simply reads those files and serves them through a local dashboard.

~/.claude/projects/  →  FastAPI (port 8020)  →  SvelteKit (port 5180)
   your data              parses & serves          visualizes it

Nothing leaves your machine. The API reads your local files, indexes metadata in a local SQLite database, and the frontend renders it all in the browser.

Live Session Tracking

This is Karma's core feature — without it, Karma is just a historical viewer. Enable real-time session monitoring by installing Claude Code hooks. See Tier 2 in SETUP.md for setup instructions.

Live sessions also get an "open terminal" button (on the session page, the home strip, and /sessions) that raises the terminal window the session is running in — Karma runs locally, so the API can ask the OS window manager directly. macOS Terminal.app and iTerm2 get the exact window/tab, tmux gets the exact pane, other macOS terminals are raised app-level, and Linux needs X11 with xdotool or wmctrl. Design details in docs/feature/open-terminal/spec.md.
