FAQPage Schema

How do I automate browser tasks like form filling and web scraping with AI agents?▼

Browser automation for AI agents is handled through a CLI-based engine with commands to open pages, fill forms, click controls, take screenshots, and scrape data across multiple sessions. It supports session isolation and ref-based interactions for reliable execution.

Can I use browser automation to test web apps across multiple sites with authentication?▼

Yes, browser automation supports testing web apps across multiple sites by utilizing multi-session isolation and authentication patterns. You can automate login flows, data extraction workflows, and form submissions across different sites without session conflicts.

What CLI commands are available for web scraping and navigating pages?▼

The CLI engine provides commands like open, fill, click, wait, and snapshot to interact with websites. These commands enable navigating pages, capturing screenshots, scraping data, and submitting forms through ref-based interactions.

Does browser automation support session isolation for concurrent tasks?▼

Yes, session isolation is a core feature of this browser automation tool. It allows AI agents to maintain independent sessions, enabling concurrent tasks like login flows and data extraction across multiple sites without cross-session interference.

What's the best way to structure assets and scripts for automated browser workflows?▼

Automated browser workflows support optional references, scripts, and assets directories to organize your automation files. This structure helps manage data extraction workflows, authentication patterns, and testing scripts across multiple sessions efficiently.

Why do I need a CLI-based engine for AI agent browser automation instead of direct API calls?▼

A CLI-based engine provides structured commands like open, fill, click, wait, and snapshot that AI agents can reliably invoke for browser automation. This approach ensures consistent ref-based interactions, session isolation, and repeatable testing workflows across web apps.
