The Problem

You switch between Cursor, Windsurf, Claude Code, VS Code Copilot, and more — each with its own siloed conversation history.

• ✗ Sessions scattered across editors, no unified view
• ✗ No idea how much you're spending on AI tokens
• ✗ Can't compare which editor is more effective
• ✗ Can't search across all your AI conversations
• ✗ No way to share session context with your team
• ✗ No unified view of your plans, credits, and rate limits

The Solution

One command. Full picture. All local.

npx agentlytics

Opens at http://localhost:4637. Requires Node.js ≥ 20.19 or ≥ 22.12, macOS. No data ever leaves your machine.

$ npx agentlytics

To only build the cache without starting the server:

npx agentlytics --collect

Relay

Relay enables multi-user context sharing across a team. One person starts a relay server, others join and share selected project sessions. An MCP server is exposed so AI clients can query across everyone's coding history.

Start a relay

npx agentlytics --relay

Optionally protect with a password:

RELAY_PASSWORD=secret npx agentlytics --relay

This starts a relay server on port 4638 and prints the join command and MCP endpoint:

  ⚡ Agentlytics Relay

  Share this command with your team:
    cd /path/to/project
    npx agentlytics --join 192.168.1.16:4638

  MCP server endpoint (add to your AI client):
    http://192.168.1.16:4638/mcp

Join a relay

cd /path/to/your-project
npx agentlytics --join <host:port>

If the relay is password-protected:

RELAY_PASSWORD=secret npx agentlytics --join <host:port>

Username is auto-detected from git config user.email. You can override it with --username <name>.

You'll be prompted to select which projects to share. The client then syncs session data to the relay every 30 seconds.

MCP Tools

Connect your AI client to the relay's MCP endpoint (http://<host>:4638/mcp) to access these tools:

| Tool | Description | |------|-------------| | list_users | List all connected users and their shared projects | | search_sessions | Full-text search across all users' chat messages | | get_user_activity | Get recent sessions for a specific user | | get_session_detail | Get full conversation messages for a session |

Example query to your AI: "What did alice do in auth.js?"

Relay REST API

| Endpoint | Description | |----------|-------------| | GET /relay/health | Health check and user count | | GET /relay/users | List connected users | | GET /relay/search?q=<query> | Search messages across all users | | GET /relay/activity/:username | User's recent sessions | | GET /relay/session/:chatId | Full session detail | | POST /relay/sync | Receives data from join clients |

Relay is designed for trusted local networks. Set RELAY_PASSWORD env on both server and clients to enable password protection.

How It Works

Editor files/APIs → editors/*.js → cache.js (SQLite) → server.js (REST) → React SPA

Relay:  join clients → POST /relay/sync → relay.db (SQLite) → MCP server → AI clients

All data is normalized into a local SQLite cache at ~/.agentlytics/cache.db. The Express server exposes read-only REST endpoints consumed by the React frontend. Relay data is stored separately in ~/.agentlytics/relay.db.

API

| Endpoint | Description | |----------|-------------| | GET /api/overview | Dashboard KPIs, editors, modes, trends | | GET /api/daily-activity | Daily counts for heatmap | | GET /api/dashboard-stats | Hourly, weekday, streaks, tokens, velocity | | GET /api/chats | Paginated session list | | GET /api/chats/:id | Full chat with messages | | GET /api/projects | Project-level aggregations | | GET /api/deep-analytics | Tool/model/token breakdowns | | GET /api/tool-calls | Individual tool call instances | | GET /api/refetch | SSE: wipe cache and rescan |

All endpoints accept optional editor filter. See API.md for full request/response documentation.

Roadmap

• [ ] Offline Windsurf/Antigravity support — Read cascade data from local file structure instead of requiring the app to be running (see below)
• [ ] LLM-powered insights — Use an LLM to analyze session patterns, generate summaries, detect coding habits, and surface actionable recommendations
• [ ] Linux & Windows support — Adapt editor paths for non-macOS platforms
• [ ] Export & reports — PDF/CSV export of analytics and session data
• [x] Cost tracking — Estimate API costs per editor/model based on token usage

Contributions Needed

Windsurf / Windsurf Next / Antigravity offline reading — Currently these editors require their app to be running because data is fetched via ConnectRPC from the language server process. Unlike Cursor or Claude Code, there's no known local file structure to read cascade history from. If you know where Windsurf stores trajectory data on disk, or can help reverse-engineer the storage format, contributions are very welcome.

LLM-based analytics — We'd love to add intelligent analysis on top of the raw data — session summaries, coding pattern detection, productivity insights, and natural language queries over your agent history. If you have ideas or want to build this, open an issue or PR.
