Free CAPTCHA Cracker: Recommended Auto-Recognition Tools

The wild side of free captcha cracking

Crawlers engaged in the old iron know that the CAPTCHA this thing is like cowhide candy can not shake off. Now even look at the weather have to first identify the location of traffic lights, the average user is too annoying, not to mention the need for batch operation of the Lord. Today we will nag how to use proxy IP with tools to break this bureau.

CAPTCHA Hacking Triple Axe

There are just three common cracks on the market:Coding Platform Burning Stream,OCR Tools White Whore Flow,Self-built model hard rigid flowThe first two are most likely to be blocked. The first two are most likely to be blocked IP, this time it is necessary to rely on the proxy IP to renew their lives. For example, with ipipgo's dynamic residential IP, each request for a different real user IP, the risk of sealing the direct waist.

The right way to open a proxy IP

Don't think just hang a proxy can do whatever you want, the market free proxy nine out of ten is a pit. I've tested it before with ipipgo's exclusive IP pool.The average daily request of a single IP is controlled within 300 times, in conjunction with random request intervals, ran for 72 hours straight without triggering wind control. On the contrary, brothers who used public proxies were blacklisted in half an hour.

Focus on the configuration essentials:

1. Don't be rigid about rotation cycles - Don't set a fixed 5 minutes to change IP, randomly switch in 3-7 minutes is more secure.
2. Request header with temperature - Remember to add a random User-Agent, not the default one that comes with the tool.
3. Failure compensation mechanisms - If the CAPTCHA fails to load, cut the IP first and retry, don't fight it.

Practical tools amenities

Here are three recommended contraptions that work well (note that they all have to be used with a proxy IP):

① Universal Recognition King - This goods can automatically adapt to common types of authentication codes, remember to fill in the settings of the ipipgo API address to the proxy module, support for socks5 and http two protocols

② Coder Terminator - Particularly suitable for picture point-and-click authentication code, you need to add your own IP pool authentication parameters in the configuration file, it is recommended to use the dynamic key authentication method provided by ipipgo

③ Lazy Man's Toolbox - Browser plug-in version for beginners, in the plug-in settings, select "custom proxy", paste the node information provided by ipipgo can be used!

Common Rollover Scene QA

Q: Why am I still recognized after changing my IP?
A: 80% of the browser fingerprint is not dealt with, with a headless browser remember to open the privacy mode, or on ipipgo's complete device fingerprint simulation services

Q: The tool shows successful recognition but no response to submission?
A: First check the latency of the proxy IP, nodes that exceed 800ms are directly replaced. In ipipgo background you can filter low latency quality lines

Q: What is the essential difference between the free version and the paid tools?
A: The free version of the public training model, the deformed text recognition pull crotch. It is recommended to use ipipgo's IP to do data collection and train the exclusive recognition model by yourself

Tell the truth.

Now that CAPTCHA technology is also evolving, it's unrealistic to expect one tool to eat everything. The key is toProxy IP + Tools + StrategyThe three-piece suite is used in combination. Like ipipgo such service providers now provide a complete anti-anti-crawl program, than you tossed to save a lot of heart. Remember, CAPTCHA cracking is essentially a cost game, find the right balance of input-output ratio is the king.
