Bytebot – Self-Hosted AI Desktop Agent

Automate any computer task with natural language

🌐 Website • 📚 Docs • 💬 Discord • 𝕏 Twitter

What is Bytebot?

Bytebot is a self-hosted AI desktop agent that transforms how you interact with computers. By combining powerful AI with a containerized Linux desktop, Bytebot can perform complex computer tasks. Think of it as your virtual employee that can actually use a computer – clicking, typing, browsing, and completing workflows just like a human would.

Why Self-Host Bytebot?

• Complete Privacy: Your tasks and data never leave your infrastructure
• Full Control: Customize the desktop environment and installed applications
• No Usage Limits: Use your own LLM API keys without platform restrictions
• Secure Isolation: Each desktop runs in its own container, isolated from your host

Examples

setup_email_example.mp4

email_json_attachment_example.mp4

☁️ Deploy on Railway (1-Click)

1. Click the Deploy Now button in the Bytebot Railway template.
2. Paste your ANTHROPIC_API_KEY in the single required environment variable.
3. Press Deploy. Railway will spin up the Desktop, Agent, UI and Postgres services using pre-built container images, connect them via private networking and expose only the UI publicly.
4. In about two minutes your agent will be live at your project's public URL.

🚀 Quick Start

Prerequisites

• Docker ≥ 20.10
• Docker Compose
• AI API key from one of these providers:
  • Anthropic (get one here) - Claude models
  • OpenAI (get one here) - GPT models
  • Google (get one here) - Gemini models

Start Your Desktop Agent (2 minutes)

1. Clone and configure:

git clone https://github.com/bytebot-ai/bytebot.git
cd bytebot

# Configure your AI provider (choose one):
echo "ANTHROPIC_API_KEY=your_api_key_here" > docker/.env    # For Claude
# echo "OPENAI_API_KEY=your_api_key_here" > docker/.env     # For OpenAI
# echo "GOOGLE_API_KEY=your_api_key_here" > docker/.env     # For Gemini

2. Start the agent stack:

docker-compose -f docker/docker-compose.yml up -d

3. Open the chat interface:

http://localhost:9992

That's it! Start chatting with your AI desktop agent. Watch it work in real-time through the embedded desktop viewer.

Example Tasks You Can Delegate

• "Research the top 5 competitors for [product] and create a comparison spreadsheet"
• "Fill out this web form with the data from my CSV file"
• "Check my email and summarize important messages"
• "Download all PDFs from this website and organize them by date"
• "Monitor this webpage and alert me when the price drops below $50"

🤖 Supported AI Models

Bytebot supports multiple AI providers to power your desktop agent:

• Anthropic Claude: Claude 3.5 Sonnet (default) - Best for complex reasoning and visual tasks
• OpenAI: GPT-4, GPT-4o - Excellent for general automation tasks
• Google Gemini: Gemini 1.5 Pro, Flash - Fast and efficient for routine tasks

Choose the model that best fits your needs and budget. Simply set the appropriate API key in your environment configuration.

🏗️ Architecture Overview

Bytebot consists of four main components working together:

📚 Advanced Usage

Programmatic Control

Control Bytebot via REST API:

import requests

# Create a task
response = requests.post('http://localhost:9991/tasks', json={
    'description': 'Search for flights from NYC to London next month',
})

task_id = response.json()['id']

# Check task status
status = requests.get(f'http://localhost:9991/tasks/{task_id}')
print(status.json())

Direct Desktop Automation

Use the computer control API for precise automation:

The core container also exposes an MCP endpoint. Connect your MCP client to http://localhost:9990/mcp to invoke these tools over SSE.
