If you’ve spent any amount of time browsing the Web, you’ve encountered captchas. This is when you need to decipher random letters and numbers within an image and type it into a box. Basically, this is to prove that you’re human.
These are a hassle on their own, but for large projects like web scraping, they’re a roadblock. This is exactly what they are meant to stop, but there are plenty of legitimate uses for web scrapers. With the rise of machine learning, many projects rely on large datasets scraped from the Web. For these types of projects, a captcha solver like 2captcha is a secret weapon.
What is CAPTCHA?
CAPTCHA is no longer an alien term to web users. It’s the annoying human validation check added on many websites. An acronym for Completely Automated Public Turing test to tell Computers and Humans Apart. CAPTCHA can be defined as a computer program developed to distinguish between the human and machine to prevent any type of illicit activity on websites. The assumption that underlies the concept of CAPTCHA is that only a human would pass this test and bot or automated scripts would fail.

Why do we need to break CAPTCHA?
Settlement of captcha on a site — is a necessity in a fight with automatic programs, spammers, brut forcers etc. CAPTCHAs are used in almost all online services to protect against automated access.
But such a defence is not always a good thing. Lots of people and businesses need to get information from sites in automatic mode. That’s why captcha services have appeared on the market that allow robots to decrypt captchas.
What is 2captcha?
2CAPTCHA is one of the best services I came across. With super quick response time and accuracy, they provide seamless services. It is the one we are going to use to bypass CAPTCHA.
Here is why 2captcha has an upper hand among its contemporaries:
- High-speed solution with 7,5 seconds for graphical and textual captchas and ~35 seconds for ReCaptcha
- Provides support for all popular programming languages with comprehensive documentation of their ready libraries.
- High accuracy (up to 99% based on the type of CAPTCHA)
- The money will be refunded for any incorrect answers
- Ability to solve a vast volume of captchas (more than 10,000 every minute).
Convolutional neural networks (CNN) have learned how to bypass the simplest types of captcha which lead captchas to active development. ANN will, of course, try to fit these changes, and captchas will become more complex — and this race will never end. That is why online anti-captcha services that involve real workers will be ahead of these solutions for the time being.
