Screenshots coming soon

• macOS 13.0 (Ventura) or later
• Xcode (for iOS Simulator support)

1. Download the latest release from Releases
2. Open the .dmg file
3. Drag Better Logger to Applications
4. Launch Better Logger

1. Select a Device

   • Choose an iOS Simulator or physical device from the sidebar
   • Booted simulators appear at the top

2. Select an App

   • Click the app picker button or enter a Bundle ID manually
   • Choose "All Apps" to stream all logs

3. Start Streaming

   • Click the "Start" button to begin streaming logs
   • Logs will appear in real-time with automatic lane discovery

4. Organize with Lanes

   • Lanes are automatically discovered from formatted logs
   • Toggle lanes on/off to focus on specific categories
   • Use the Lanes Grid View (⌘G) for side-by-side comparison

Better Logger automatically discovers lanes from logs formatted like:

[CATEGORY](level) [File.swift:42 method()] Your log message

Example:

[NETWORK](info) [APIService.swift:150 fetchUsers()] GET /api/users - 200 OK
[UI](debug) [LoginView.swift:25 viewDidLoad()] Login screen appeared
[AUTH](warning) [AuthManager.swift:80 validateToken()] Token expiring soon

• ⌘S - Save current session
• ⌘G - Open Lanes Grid View
• ⇧⌘H - Open Saved Sessions
• ⇧⌘M - Toggle MCP Server
• ⌘, - Open Settings

1. Open Format Settings (gear icon)
2. Choose a preset or create custom patterns
3. Configure Lane Pattern (regex) to extract category and level
4. Configure Source Pattern (regex) to extract file, line, and method
5. Test your patterns with sample log messages

Better Logger includes a full MCP (Model Context Protocol) server, enabling integration with AI assistants like Cursor.

1. Start the MCP Server in Better Logger (View → Start MCP Server)
2. Click the MCP status indicator in the toolbar
3. Click "Install Bridge" - this installs the bridge to ~/.better-logger/mcp-bridge
4. Copy the generated Cursor config
5. Add it to ~/.cursor/mcp.json
6. Restart Cursor

• list_devices - List available iOS simulators and physical devices
• list_sessions - List saved log sessions
• list_lanes - List discovered log lanes
• get_logs - Get current live logs (with filters: lane, level, search, limit)
• get_session_logs - Get logs from a saved session
• start_log_stream - Start streaming logs from a device
• stop_log_stream - Stop the current log stream

You: "Show me all network errors from the current log stream"

Cursor: [Uses get_logs tool with level=error and lane=NETWORK]

[GENERAL](debug) [AppDelegate.swift:20 applicationDidFinishLaunching()] App launched

If your logs use a different format, configure custom patterns:

Input: [2025-01-15 10:30:45] [ERROR] [AuthService] Login failed

Lane Pattern: \[(\w+)\] (captures "AuthService") Source Pattern: (optional, if you include file:line in logs)

1. Check if port 8765 is already in use
2. Ensure firewall allows local connections
3. Check MCP debug logs in the status popover

1. Verify the simulator is selected
2. Check that the app is running on the device
3. Try "All Apps" instead of a specific bundle ID
4. Ensure logs are using a supported format

• Built with SwiftUI
• MCP protocol implementation based on Model Context Protocol specification
