kernel create

Create a new Kernel application from a template. The CLI provides an interactive prompt to guide you through selecting a language and template, or you can specify all options via flags.
FlagDescription
--name <name>, -nName of the application directory to create.
--language <language>, -lProgramming language: typescript (ts) or python (py).
--template <template>, -tTemplate to scaffold (see available templates below).
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
  • advanced-sample — Demonstrates advanced Kernel configurations
  • stagehand — Returns the first result of a specified Google search
  • computer-use — Implements Anthropic’s Computer Use API in a prompt loop
  • cua — OpenAI Computer Using Agent (CUA) sample implementation
  • gemini-cua — Google Gemini CUA sample implementation
  • magnitude — Magnitude framework integration

​
Python templates

  • sample-app — Basic template with Playwright integration for page title extraction
  • advanced-sample — Demonstrates advanced Kernel configurations
  • browser-use — Integrates the Browser Use for AI-powered web automation
  • computer-use — Implements Anthropic’s Computer Use API in a prompt loop
  • cua — OpenAI Computer Using Agent (CUA) sample implementation

​
Examples

# 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 computer-use

Next steps

After creating your app:
  1. Navigate to the project directory: 
    cd my-app
  2. Install dependencies:
    • TypeScript: npm install
    • Python: uv venv && source .venv/bin/activate && uv sync
  3. Authenticate with Kernel: 
    kernel login or export KERNEL_API_KEY=<YOUR_API_KEY>
  4. Deploy your app: 
    # TypeScript
kernel deploy index.ts

# Python
kernel deploy main.py
  5. Invoke your app: 
    kernel invoke my-app action-name --payload '{"key": "value"}'
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.
