2025-08-21 293

Background to the issue

High-frequency data crawling may trigger anti-crawling mechanisms, Simular Browser provides multiple protection solutions.

Core Solutions

  • interval setting: Configure a random delay of 5-30 seconds in "Advanced Settings - Capture Interval" to simulate the rhythm of human operation.
  • IP RotationCloud mode automatically enables the global node IP pool, while local mode allows access to third-party IP services through "proxy settings".
  • Header disguise: Check the "Emulate device type" option to automatically rotate User-Agent (including Chrome/Firefox/Safari mobile/PC).
  • CAPTCHA handling: Pro version integrates OCR recognition and automatically pauses and pops up a human intervention window when it encounters a CAPTCHA.

Emergency program

If still blocked: 1) Switch to mobile data network 2) Use "deep camouflage mode" (will reduce 20% speed) 3) Contact technical team to customize crawling strategy.
