Browser spin-up time

Non-standard configuration can affect browser spin-up time. Settings like non-default viewport sizing, extensions, or Profiles may increase the time it takes for a browser to become ready. Standard configuration includes:
  • Headful and headless browsers
  • Stealth mode both enabled and disabled
If you’re experiencing slower-than-expected browser creation times, review your configuration to identify any non-standard settings that may be contributing to the delay.

​
Connection notes

  • CDP connections are meant to be long-lived but may eventually close. Websocket connections typically can remain active for up to 1 hour, after which they may close automatically. Browser sessions themselves are unaffected—reconnect to the same cdp_ws_url to continue using the browser.
  • Browsers persist independently of CDP. Depending on your timeout configuration, it will continue running even if the CDP connection closes. You can reconnect to the same cdp_ws_url if you’re unexpectedly disconnected.
  • We recommend implementing reconnect logic, as network interruptions or lifecycle events can cause CDP sessions to close. Detect disconnects and automatically re-establish a CDP connection when this occurs.

Site difficulty index

A rough grouping of sites by how much friction we see when running stealth Kernel browsers against the public landing page. This list is incomplete and will grow over time.

​
Hard — significant friction observed

Most or all sessions were blocked or challenged.
  • Yelp
  • Glassdoor
  • Indeed
  • TripAdvisor

​
Light — partial friction observed

Some sessions were blocked or challenged.
  • Yellow Pages
  • Zillow

​
Clear — no blocks observed at this layer

All sessions returned a usable page. These sites still deploy bot detection — login flows, deep navigation, and high-volume scraping behave very differently — but the public landing page renders cleanly.

Hitting friction on a site that’s listed under Clear? Check your proxy type and confirm you’re not running headless — those are the two most common causes of unexpected detection.
