Contop

Your Desktop, From Anywhere

AI-powered remote desktop control from your phone

Website • Docs • Releases

---

Contop turns your phone into an AI remote control for any desktop. Speak or type a command on your mobile, and an autonomous agent on your computer observes your screen, runs CLI commands, clicks buttons, fills forms, automates browsers, and streams progress back - all in real time over a peer-to-peer WebRTC tunnel.

No port forwarding. No VPN. No SSH. Scan a QR code and start working.

Install

Desktop App

macOS (Homebrew - recommended):

brew install slopedrop/contop/contop

# Update to latest version
brew update && brew upgrade contop

No security warnings. Python dependencies install automatically on first launch.

macOS (manual): Download the .dmg from Releases, open it, and drag to Applications.

First launch: right-click the app → Open → click Open in the dialog. This is standard for open-source apps without code signing.

Windows (Scoop - recommended):

scoop bucket add contop https://github.com/slopedrop/scoop-contop
scoop install contop

# Update to latest version
scoop update && scoop update contop

No SmartScreen warnings. Python dependencies install automatically on first launch. NVIDIA GPU with CUDA is auto-detected.

Windows (manual): Download the .exe installer from Releases and run it.

SmartScreen may show a warning - click More info → Run anyway. This is standard for open-source apps without code signing.

Linux:

# AppImage (any distro)
chmod +x Contop*.AppImage && ./Contop*.AppImage

# Debian / Ubuntu
sudo dpkg -i contop-desktop_*.deb

Download from Releases.

Mobile App

Download the Android .apk from Releases.

Enable Install from unknown sources when prompted.

iOS is not yet available for public alpha.

Features

Autonomous AI Agent

• 30+ execution tools - CLI, GUI automation, file operations, browser control, window management, document processing, app lifecycle, and more
• Smart vision routing - 9 backends: OmniParser V2, Gemini Computer Use, Accessibility Tree, and 6 OpenRouter vision models (UI-TARS, Kimi, Qwen, Phi, Molmo, Holotron)
• Multi-step planning - plan-generation tool with research sub-agent, tool chaining, and up to 50 iterations per task
• Multi-provider LLM - Gemini, OpenAI, Anthropic, and OpenRouter (100+ models including Groq, Mistral, DeepSeek, and more) via LiteLLM
• Subscription mode - use your existing Claude Pro/Max, Gemini Pro, or ChatGPT Plus/Pro subscription instead of API keys via the built-in CLI proxy (Claude Code, Gemini CLI, Codex CLI - text-only, no LLM vision fallback)
• Skills system - extensible via SKILL.md standard with YAML workflows and Python tool loading
• Real-time feedback - step-by-step progress, screenshots, and model/backend transparency streamed to your phone

Security

• Dual-Tool Evaluator - every command classified and routed through a security gate before execution
• Destructive action approval - dangerous operations require explicit user confirmation
• Sandboxed execution - high-risk commands run in an isolated Docker container
• Restricted path isolation - prevents agent from accessing protected directories
• JSONL audit log - every tool call logged with timestamps, commands, and outcomes
• Away Mode - PIN-locked secure overlay with auto-engage on idle (Windows)

Connectivity

• QR code pairing - scan to connect with 30-day persistent tokens, no IP configuration needed
• Cloudflare Tunnel - automatic public URL, zero port forwarding
• WebRTC P2P - dual data channels (reliable + unreliable) with live video streaming
• Paired device management - geo-location tracking, connection path visibility, per-device revoke, OS notifications
• Connection loss resilience - automatic execution kill on disconnect, chat-only fallback mode

Desktop App (Tauri v2)

• Lightweight native shell (Rust) with settings GUI
• Manages the Python server as a sidecar process
• API key and subscription mode configuration, security rules, system prompts
• CLI proxy lifecycle management - auto-start, health monitoring, and watchdog restart
• Cross-platform: Windows, macOS, Linux

Mobile App (Expo / React Native)

• Adaptive layouts: split-view, side-by-side, fullscreen video, thread-focus
• Real-time execution thread with tool outputs and screenshots
• Session history with persistence and restore
• Model selection, extended thinking toggle, custom instructions

Development Setup

Prerequisites

• Python 3.12+ with uv
• Node.js 18+
• At least one LLM API key: Gemini, OpenAI, Anthropic, or OpenRouter - or an existing Claude Pro/Max, Gemini Pro, or ChatGPT Plus/Pro subscription via the built-in CLI proxy
• Android / iOS device with Expo dev build

1. Start the Server

cd contop-server
uv sync
uv run uvicorn main:app --host 0.0.0.0 --port 8000

2. Run the Desktop App (optional)

cd contop-desktop
npm install
npm run tauri dev

3. Run the Mobile App

cd contop-mobile
npm install
npx expo run:android   # or: npx expo run:ios

4. Pair and Go

1. Open the desktop app (or visit http://localhost:8000) to see the QR code
2. Scan the QR code from the mobile app
3. Start speaking or typing - the agent observes your screen and executes your commands

For detailed setup, platform-specific instructions, and configuration options, see the full documentation.
