1. Handling Client-Side Rendering (CSR) and SPA
Web Speed doesn’t just scrape raw HTML. When you use interpret_page(js=true) or
evaluate(), it spins up a full Playwright-powered browser engine.
– Hydration Wait: This executes the site’s JavaScript, waiting for the application to mount,
And only then executes the mapping.
– State awareness: Tools like wait_for_element and wait_for_url allow the agent to pause
Until the client-side router has finished loading the specific view.
2. Bypassing bot detection
Standard scraping libraries often fail because they use a “clean” environment. web speed
Allows the agent to connect to your real browser (via CDP):
– Real Fingerprint: This captures your active sessions, cookies and hardware
fingerprint.
– Human-like interaction: fill_field(use_keyboard=true) simulates real keystrokes
Instead of setting just one .value, which bypasses the many “Trusted Input” checks used
Modern anti-bot layers (like on X or Amazon).
3. Lazy-loading and dynamic sections
For infinite-scroll or lazy-loaded content, Web Speed Agent uses a validation loop:
– The agent can use evaluate() to scroll the page or trigger a custom event
(send(‘scroll’)).
– It then calls read_page again to capture the newly injected nodes, ensuring the “map”.
Stays updated with the dynamic status of the application.
