CAPTCHA Solver FAQs
How does the CAPTCHA Solver work?

See detailed pricing page for Web Unlocker pricing
Is CAPTCHA solving automatic, or do I need to enable it?
CAPTCHA solving is automatically enabled by default across all Browser API sessions. Our integrated solver automatically detects and solves all types of CAPTCHAs (reCAPTCHA, FunCAPTCHA, hCAPTCHA, Cloudflare challenges, etc.) without any additional configuration. Once a CAPTCHA is solved, any associated forms will be automatically submitted by default.
Can I disable CAPTCHA solving for specific types or completely?
Yes, you have full control over CAPTCHA solving behavior. You can:
- Disable completely: Use
Captcha.setAutoSolve({ autoSolve: false })to turn off all CAPTCHA solving - Disable by type: Configure specific CAPTCHA types (like reCAPTCHA only) by setting
disabled: truein the options array - Manual control: Disable auto-solve and then manually trigger solving using
Captcha.solve()when needed
You can also disable CAPTCHA solving entirely through the Control Panel settings if you prefer a global configuration approach.
How can I monitor the CAPTCHA solving process and handle failures?
You can monitor CAPTCHA solving using our custom CDP events and commands:
- Status tracking: Use
Captcha.solve()to get detailed status information including solve results and error messages - Event monitoring: Listen for specific events like
Captcha.detected,Captcha.solveFinished,Captcha.solveFailed, orCaptcha.waitForSolve - Failure handling: If CAPTCHA solving fails, attempt a retry. For persistent issues, submit a support request with specific problem details
The solver returns status codes like solve_finished, solve_failed, not_detected, or invalid to help you understand what happened during the solving process.
