What problem does it solve?

cmux-browser automates end-user browser tasks inside cmux webviews to open sites, interact with pages, wait for state changes, and extract data from surfaces.

Core Features & Use Cases

  • Open and target a browser surface, verify navigation with get url, take snapshots, interact with elements via click, fill, type, or press, wait for state changes, and re-snapshot after DOM/navigation changes.
  • Use cases include end-to-end form automation, login flows, data extraction, and automated testing of web interfaces.

Quick Start

Open a surface, navigate to a URL, snapshot to collect refs, then perform actions like click or fill and re-snapshot as needed.

How do I automate end-user browser tasks inside webviews?▼

Automate end-user browser tasks inside webviews by opening a browser surface, navigating to a URL, taking snapshots to collect refs, and performing actions like click, fill, type, or press.

What is surface isolation and why is it needed for browser automation?▼

Surface isolation separates browser automation contexts across surfaces, ensuring that tasks like login flows and data extraction run independently without session conflicts.

How do I keep browser automation refs stable after DOM changes?▼

Keep browser automation refs stable by managing the ref lifecycle and re-snapshotting surfaces after DOM or navigation state changes to capture updated element references.

What's the best way to wait for page load states during webview automation?▼

Wait for page load states during webview automation by applying wait patterns that pause execution until specific page loading or state change conditions are met.

Can I extract data from web interfaces using browser snapshots?▼

Extract data from web interfaces by taking snapshots to collect element refs, interacting with pages via actions, and re-snapshotting after DOM changes to capture the resulting data.

Do I need any external dependencies to run cmux browser automation?▼

No external dependencies are required; the skill operates independently to provide templates and references for navigating sites, performing actions, and waiting for load states.
