Cursor Remote Lite

Product Introduction

1. Definition: Cursor Remote Lite is a self-hosted, open-source remote control server and mobile client application designed specifically for the Cursor AI code editor. It operates as a Node.js-based relay that connects to Cursor's Chrome DevTools Protocol (CDP) interface, enabling bidirectional communication and control from a mobile device.
2. Core Value Proposition: It exists to liberate developers from their physical workstations by providing a dedicated, secure, and feature-rich mobile interface to manage Cursor's AI Agent workflows remotely. Its core value is enabling continuous development work—tasking, monitoring, and interacting with AI Agents—from anywhere, without requiring the laptop to be physically present or relying on cumbersome remote desktop solutions.

Main Features

1. Full Cursor Agent Interaction: Provides a chat-style mobile interface to view the entire Agent conversation, including thought processes and tool call cards. Users can send new messages, approve commands, and answer Agent questions directly from their phone. Messages sent while an Agent is running are automatically queued.
2. Multi-Window & Environment Control: Allows switching between all Cursor window types: local projects, SSH remote sessions, and dedicated Agents windows. Users can also change the active model (e.g., Claude 3.5 Sonnet, GPT-4), adjust model parameters (context length, effort level), and toggle modes (Agent, Plan, Ask) remotely.
3. Secure, Self-Hosted Architecture with Persistent Access: The core server runs on the user's own computer. It establishes a persistent, fixed public URL via a Cloudflare Tunnel (HTTPS/WebSocket). The mobile client (hosted on the user's personal GitHub Pages) connects to this tunnel. All code and AI conversations remain on the user's machine; no data passes through third-party AI servers.
4. Intelligent File Management & Preview: Detects and lists files modified by the Agent, showing line addition/deletion counts. Users can preview the full content of any file mentioned in the chat or modified by the Agent, with syntax highlighting where applicable. For SSH windows, files are read directly via the established SSH connection from the host computer.
5. Push Notifications & Real-Time Screen View: Sends push notifications to the mobile device when an Agent completes a task or is waiting for user confirmation (e.g., to run a command). Includes a real-time screen view mode to see the actual Cursor interface, with support for basic interactions like clicking and scrolling.

Problems Solved

1. Pain Point: The inability to effectively monitor and guide long-running AI Agent tasks when away from the primary development machine. Traditional solutions like remote desktop offer poor mobile UX, while official mobile apps may be platform-restricted, require paid tiers, or lack support for key environments like SSH.
2. Target Audience: Software developers, DevOps engineers, and technical leads who use Cursor AI extensively for coding, debugging, and refactoring, especially those who work across multiple machines (e.g., local laptop and remote servers) or have workflows that involve waiting for Agent cycles.
3. Use Cases: Essential for scenarios like: continuing to oversee a bug-fix Agent running on a company server while commuting; answering an Agent's clarifying question during a meeting away from the desk; reviewing and approving file changes made by an Agent after leaving the office; or quickly issuing a follow-up task to an Agent from a mobile device without interrupting its current operation.

Unique Advantages

1. Differentiation: Compared to Cursor's official iOS Remote Control (paid, iOS-only, cloud-based Agent loop) and third-party solutions like len5ky/CursorRemote (freemium, source-available), Cursor Remote Lite is completely free, MIT-licensed, and fully open-source. It supports both Android and iOS (via PWA), controls all window types, and keeps all processing on the user's hardware.
2. Key Innovation: Its use of a user-owned GitHub Pages repository as a static, fixed endpoint for the mobile client, combined with encrypted dynamic tunnel information stored there. This decouples the client deployment from the server's changing tunnel address, providing a stable access point without requiring a dedicated static IP or domain, while maintaining a zero-cost, self-hosted model.

Frequently Asked Questions (FAQ)

1. Is Cursor Remote Lite secure? How does authentication work? Authentication is passwordless and uses a one-time pairing system. A QR code/link generated on the host computer contains a random secret and pairing code valid for 10 minutes. Upon scanning, the mobile device receives a unique device token. The host only stores a hash of this token. The public GitHub Pages repository contains an encrypted version of the host's address, with the key only shared during the initial pairing.
2. Does it work with Cursor's SSH remote development feature? Yes, this is a core feature. Cursor Remote Lite can connect to and control Cursor windows that are attached to SSH remote sessions. File previews for these sessions are accomplished by the host computer's relay executing ssh commands to the remote server (assuming SSH key-based authentication is already configured for Cursor).
3. What happens if my computer goes to sleep? The connection will be lost, and any active Agent task will pause. The mobile app will show the host as offline. To use Cursor Remote Lite effectively, you must configure your computer's power settings to prevent sleep while allowing the display to turn off (e.g., pmset -c sleep 0 on macOS). The service and connection will automatically resume when the computer is awakened.
4. Can I use it on an iPhone without installing from the App Store? Yes. For iPhone users, you can access the web client via Safari and use the "Add to Home Screen" feature to create a full-screen Progressive Web App (PWA). This PWA can also receive push notifications on iOS 16.4 and above.
5. How does the free Cloudflare Tunnel affect reliability? The free Cloudflare Tunnel (aka "Quick Tunnels") provides a stable HTTPS URL but does not have an uptime Service Level Agreement (SLA). Occasional disconnections may occur. If the tunnel restarts and gets a new URL, the host's server.mjs will automatically update the encrypted address in your GitHub Pages repository, and the mobile client will reconnect within about a minute without requiring re-pairing.
