Code Insights

A free, open-source, local-first tool for analyzing AI coding sessions.

Parses session history from Claude Code, Cursor, Codex CLI, and Copilot CLI. Stores structured data in a local SQLite database. Surfaces insights through terminal analytics and a built-in browser dashboard.

No accounts. No cloud. No data leaves your machine.

Quick Start

npm install -g @code-insights/cli

code-insights init      # Set up config and local database
code-insights sync      # Parse sessions from all detected AI tools
code-insights dashboard # Open the built-in dashboard at localhost:7890

What It Does

• Multi-tool support — parses sessions from Claude Code, Cursor, Codex CLI, and Copilot CLI
• Terminal analytics — code-insights stats shows cost, usage, and activity breakdowns
• Built-in dashboard — browser UI for session browsing, analytics charts, and LLM-powered insights
• Auto-sync hook — install-hook keeps your database up to date automatically
• LLM analysis — generates summaries, decisions, learnings, and techniques from session content (via your own API key or local Ollama)

Supported AI Tools

Tool	Data Location
Claude Code	~/.claude/projects/**/*.jsonl
Cursor	Workspace storage SQLite (macOS, Linux, Windows)
Codex CLI	~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl
Copilot CLI	~/.copilot/session-state/{id}/events.jsonl

The monorepo contains three packages:

• cli/ — Node.js CLI, session providers, SQLite writes, terminal analytics
• server/ — Hono API server, REST endpoints, LLM proxy (API keys stay server-side)
• dashboard/ — Vite + React SPA, served by the Hono server

Development

git clone https://github.com/melagiri/code-insights.git
cd code-insights
pnpm install
pnpm build
cd cli && npm link
code-insights --version

See cli/README.md for the full CLI reference, and CONTRIBUTING.md for contribution guidelines.

Privacy

Session data stays on your machine in ~/.code-insights/data.db. No accounts, no cloud sync, no telemetry beyond anonymous usage counts. LLM analysis uses your own API key (or Ollama locally) — session content goes only to the provider you configure.
