Installation

Install OpenSteer, install a browser, then verify the runtime you plan to use.

Prerequisites

• Node.js 22 or newer
• Chromium installed through Playwright if you plan to use the default local engine

Install the package

Install the published package in application code:

npm install opensteer

If you want the CLI on your path:

npm install -g opensteer

You can also run the CLI without a global install:

npx --yes opensteer@latest --help

Install the Playwright browser

OpenSteer uses the Playwright-backed engine by default.

npx playwright install chromium

Optional: use a specific local Chrome build

If you want OpenSteer to launch a specific local browser binary, point it at that executable:

export OPENSTEER_EXECUTABLE_PATH=/path/to/chrome

Install first-party skills

Install the default opensteer skill pack:

opensteer skills install

Install every packaged skill:

opensteer skills install --all

Install for a specific agent:

opensteer skills install --agent claude-code

Optional: install the ABP engine

If you want the Agent Browser Protocol engine locally:

npm install @opensteer/engine-abp

ABP is local-only. Cloud mode currently requires Playwright.

Optional: cloud environment

Cloud mode needs the provider switch plus an API key and base URL:

export OPENSTEER_PROVIDER=cloud
export OPENSTEER_API_KEY=your_api_key
export OPENSTEER_BASE_URL=https://your-control-api

OPENSTEER_CLOUD_APP_BASE_URL is only required for opensteer record --provider cloud.

Verify

Check provider resolution and workspace status:

opensteer status

Check the package version:

opensteer --version

If local Playwright is installed correctly, the next step is Quick Start.
