1 Comment on EndCaptcha for fast CAPTCHA solving

endcaptcha From time to time, web users struggle with “CAPTCHA services” such as DeCaptcher and DBC. And although those services are reliable, often times they’re “overloaded”, meaning the images to be solved get rejected or it takes a lot of time to be decoded (some services might even take 50 seconds to solve a single image!).

But, I recently came across a new service that hopes to fill this (fast CAPTCHA solving) gap. EndCaptcha.com, is a new image digitization service that was built to satisfy the needs of the most demanding consumers. It uses a dedicated team of operators assisted by a smart OCR system. That’s why it’s being considered a Premium CAPTCHA service.

Captcha Breaker Review

GSA Captcha Breaker is a CAPTCHA solving software. It uses Optical Character Recognition algorithms for CAPTCHA decoding. Being a standalone program it works independently of any online captcha recognition services (like DeathByCaptcha, BypassCaptcha and etc). This means that once you have paid for the program you don’t need to pay for each recognition anymore, and this allows you to save money when you need to recognize a huge amount of CAPTCHAs.

DeCaptcher Review

Recently we came across a CAPTCHA solving service called DeCaptcher. As we proceed with the new Scraper Test Drive stage, we have encountered some off-the-shelf scrapers that use a 3rd party service for CAPTCHA solving. The DeCaptcher service is the most popular among them.

TEST DRIVE: CAPTCHA

The new Scraper Test Drive stage is on, called CAPTCHA. What can the scrapers perform to get through the “robot fighters”? The off-the-shelf scrapers are not designed for CAPTCHA solving by default. Furthermore, some stated that “bypassing Captchas was compatible with Internet good ethics”. I agree with this, but for the full Scraper Test Drive taste, we still want to try out the scrapers.
