Common / Best captcha bots?

Ok so I want to start developing my own in-house captcha system, which I've done before but with no real safe-testing against captcha breakers..

Do any of you know of common / the best captcha bots out there that I can download / buy?

And before anyone flames me, I assure you it's for educational / development purposes..

Please help me out if you know anything about these systems!

 

There are many companies which provide captcha solving solution like death by captcha


But if you are looking your own script to solve different capatcha then we will suggest to use OCR technology to develop a application and in turn a solution like Deathbycaptch. captcha solving companies do the same.

I work in a IT company in Pune India and currently we are developing this captcha solving solution for one of our client from Europe.

 

Thanks chaudhari.. Thats exactly what I was looking for.. But since it's no interest of mine other than for this single project, I just had no idea where to start..


Thanks again!

 

Chuckun then its always better to use API's from other capatcha solving companies.
