--language <language>, -lProgramming language: typescript (ts) or python (py).
--template <template>, -tTemplate to scaffold (see available templates below).

INFO

If any option is omitted, the CLI will prompt you interactively.

Available templates ​

TypeScript templates ​

  • sample-app , Basic template with Playwright integration for page title extraction
  • captcha-solver , Demo of Kernel's auto-CAPTCHA solving capability
  • anthropic-computer-use , Anthropic Computer Use API sample implementation
  • openai-computer-use , OpenAI Computer Using Agent (CUA) sample implementation
  • gemini-computer-use , Google Gemini CUA sample implementation
  • stagehand , Returns the first result of a specified Google search
  • magnitude , Magnitude framework integration

Python templates ​

  • sample-app , Basic template with Playwright integration for page title extraction
  • captcha-solver , Demo of Kernel's auto-CAPTCHA solving capability
  • openagi-computer-use , OpenAGI's Lux Computer Use API sample implementation
  • anthropic-computer-use , Anthropic Computer Use API sample implementation
  • openai-computer-use , OpenAI Computer Using Agent (CUA) sample implementation
  • browser-use , Integrates the Browser Use for AI-powered web automation

Examples ​

bash
# Interactive mode (prompts for all options)
kernel create

# Create a TypeScript app with the sample template
kernel create --name my-app --language typescript --template sample-app

# Create a Python app with Browser Use
kernel create --name my-scraper --language python --template browser-use

# Create a TypeScript app with Stagehand (shorthand language flag)
kernel create --name my-agent --language ts --template stagehand

# Create a Python Computer Use app
kernel create --name my-cu-app --language py --template anthropic-computer-use

Next steps ​

After creating your app:

  1. Navigate to the project directory:

    bash
    cd my-app

  2. Install dependencies:

    • TypeScript: npm install
    • Python: uv venv && source .venv/bin/activate && uv sync

  3. Authenticate with Kernel:

    bash
    kernel login or export KERNEL_API_KEY=

  4. Deploy your app:

    bash
    # TypeScript
kernel deploy index.ts

# Python
kernel deploy main.py

  5. Invoke your app:

    bash
    kernel invoke my-app action-name --payload '{"key": "value"}'

INFO

Some templates require environment variables (e.g., OPENAI_API_KEY, ANTHROPIC_API_KEY). Set them using --env or --env-file flags when deploying. See kernel deploy for details.
