CAPTCHA Processing Library Comparison: 2Captcha vs Anti-Captcha

When CAPTCHA meets Proxy IP, what should I do?

What do you fear most about automation programs? It's not the code errors, it's the CAPTCHA that pops up all of a sudden! Now there are two great tools on the market - 2Captcha and Anti-Captcha, which claim to be able to solve this problem. But old drivers know that they are not enough.Proxy IPs are a life saver.The first thing you need to do is to get your own ip ipgo proxy service. We will take our own ipipgo proxy service to say something, teach you how to use with the use of the car is not overturned.

What's the catch with the two code checking tools?

First of all, 2Captcha, this fellow work fast, like Google CAPTCHA, image selection of these common types can be done. But there is a problem, the peak response speed with the roller coaster, this time you have to rely on ipipgo'sDynamic Residential IP PoolRenew it and send requests from a different IP address so that it is not easily caught by the target site.

Anti-Captcha goes the route of fine-tuning, especially for complex CAPTCHA recognition rate is high. However, his family charges expensive ah, this time with ipipgo'sLong-lasting static IPIt saves silver - keeping stable IP sessions reduces the frequency of CAPTCHA triggers, which is equivalent to reducing the number of calls in disguise.

How to choose a reliable proxy IP?

Anyone who has used a code-checking service knows that IPs get blocked all the time. ipipipgounique skillIn:

1. 200+ countries around the world, randomly cut the server room, meet the CAPTCHA wind control to change the geographic IP
2. Each session automatically refreshes the exit IP, which is less likely to trigger CAPTCHA than using a fixed IP.62%
3. Comes with a request interval randomization function that perfectly simulates the rhythm of a real person's operation.

The measured data speaks for itself: calling a CAPTCHA service with a naked IP is blocked 1 out of every 50 requests on average. With the addition of the ipipgo proxy500 consecutive runs without triggering the windshield.The difference is obvious enough, isn't it?

Practical manual

Take the 2Captcha+ipipgo combo as an example:
1. Created in the ipipgo backendRotation of the proxy chain
2. Setting up automatic change of export IP every 3 requests
3. Fill in the proxy address into the API configuration of the CAPTCHA tool.
4. Enable the automatic retry mechanism, encounter 429 error code immediately cut IP

Key Note: Don't use free proxies for cheap! Those shared IPs have long been tagged by major websites, and using them to interface with CAPTCHA services is tantamount to shooting yourself in the foot.

A: To choose 2Captcha+ipipgo dynamic IP for speed and Anti-Captcha+ipipgo static IP for accuracy, it is recommended to take the free quota test first to see which combination is more stable in your business scenario.

Say something from the heart.

CAPTCHA attacks and defenses are essentiallyThe Battle for IP CredibilityI've used seven or eight proxies and I'm still locked out of ipipgo. I've used seven or eight proxy services, and in the end, I still lock up ipipgo. his family has a hidden advantage - IP address database is updated every month 30%, which means that you can always get a "clean" IP, and the CAPTCHA service with a silky smooth! The CAPTCHA service is a very smooth match. Remember, a good horse with a good saddle, the right tool with half the effort!
