agent-browser

You can automate web form filling and data scraping from the command line by using a CLI browser automation tool to control a headless browser, navigate pages, and interact with elements. It applies ref-based element selection to script interactions via Bash commands.

Ref-based element selection works by snapshotting the page's accessibility tree to generate unique references for interactive elements. You then use these refs in CLI commands to click, fill, and type, ensuring precise scripted interactions without relying on traditional CSS selectors.

Yes, you can run parallel web scraping tasks across multiple isolated browser sessions. The tool supports parallel browsing sessions, allowing you to handle multiple isolated automation workflows simultaneously from your command line.

Yes, you need to install agent-browser globally to use CLI web automation commands. This environment setup provides the necessary command-line interface to control the headless browser, execute Bash commands, and perform web tasks like taking screenshots.

The best way to capture page screenshots and generate PDFs during web automation is to use CLI browser commands within your scripted workflow. This enables automated visual verification and reporting directly from your command line interface.

Semantics-based element finding serves as an alternative to refs for locating elements, but refs provide more precise element targeting. Using accessibility tree snapshots with refs ensures accurate CLI interactions, which can be limited if elements lack clear semantic identifiers.
