Captcha Trader, Automatic Free Captcha Solving For JDownloader

The majority of file hosting websites make use of captchas when free account users or guests try to download files from their servers. For me, that's more of a way to make the downloads less convenient to convince more users to upgrade to a premium account. Still, there is not much you can do if you need to download a file from the hosting server.

I already mentioned earlier today that I like to use the JDownloader software to download files from file hosting services. It is more convenient, especially since it saves the download queue so that downloads can be resumed at any time. Captchas on the other hand still need to be filled out. That's a problem if you need to leave the computer for a longer period of time, or if you do not want the captchas to disturb you from other computer activities.

Ghacks reader KoalaBear suggested to use the plugin Captcha Trader for automatic captcha solving. The service is offered as a plugin for JDownloader, MiPony and a handful of other popular downloaders. It basically allows the user to either buy credits or solve captchas in advance so that captchas in JDownloader are resolved automatically by the plugin.

Here is how Captcha Trader works.

  • Visit the Captcha Trader website and create an account.
  • Switch to the Plugins directory on the site and download the plugin for your software and operating system. I'm going to demonstrate how to add the plugin to JDownloader. Readme files are included that explain how the plugins are installed.
  • Extract the folder and copy it to the \JDownloader\jd\captcha\methods\ folder.
  • Edit with a text editor and add your username and password to the file.
  • Restart JDownloader.

The plugin will not show up in JDownloader. It won't work right away since you do not have any credits in the beginning. That is, unless you have bought credits on the site. 10000 credits on the site, good for at least 1000 solved captchas cost $6 Dollars.

Instead of paying, users can earn credits by solving captchas on the Captcha Trader website. A click on Earn Credits displays a captcha every 50 or so seconds. Solving the captcha correctly will award credits to the account.


Users earn seven credits for text recognition captchas, and three for image recognition captchas. It costs ten credits to solve text captchas, and five credits to solve image recognition captchas.

It is furthermore possible to cash out at anytime. 10000 credits equate $1.

Once you got enough credits, captchas are automatically resolved in the software you use to download files from file hosts. The captcha should not pop up anymore which is great if you need to work full screen.

Update: Captcha Trader seems to have been discontinued and we are not aware of any free solution that works with JDownloader at the moment.

    Invented inventions of HowTo’s making money profits on users back from to captcha’s and downloads ! We user do have nothing but trouble – forcing to pay for something that is illegal and as reg user one can have huge trouble in case of fall down of such services due to authorities ! Why do you think that everywhere on net is user almost everywhere forced to register to services ! With filehosting services one is absolute not anonymous and less secure !
    Forget filehosting services and use the future P2P today – MUTE, TRIBLER magnet links and similar ! One have much better security by default as with direct links on filehosting ! Its only question of time when they will fall and to save their asses they will reveal all reg users as this has hapened with megaupload/filesonic !

    Share your shit on decentralized networks so everyone interested have access if desired and not only few users that making money from others with illegal way !

    Free knowledge for free people on free internet !!!

    There is also Remote Captcha for iPhone, which sends the CAPTCHA to your iPhone and you can solve it right there. You get notified when there is a CAPTCHA to solve no matter where you are. You can see a video and download the App here:

    here is a real free alternative:
    that’s much better. you don’t have to solve thousands of captcha. get credits as you go and use whatever you have.

    1. KoalaBear said on August 21, 2011 at 8:49 pm

      That is really the same as Captcha trader! Solve captchas and get solved captchas in return. For Captcha trader you dont have to solve thousands of captchas.

    Somehow it doesn’t work for me. I’ve around 300 credits on the website; even then I’m asked to resolve Captchas for whatever links I add. Any indication from the UI that it’s configured properly, or otherwise?

    1. Martin Brinkmann said on August 21, 2011 at 7:51 am

      No you do not get any indicator. Have you entered your login details into the file? I missed that step on first try and it did not work because of this. If you have, double-check that they are correct. One thing that comes to mind: Can it be that Captcha.Trader is not supporting all file hosting sites? Have you tried different sites? It worked well on Oron for me.

    10000 / 7 =1429 times solving captchas to earn just one dollar..

    1429 * 6 = 8,574 times to earn 6 dollars to automatically solve 1,000 captchas… that’s a lot of time..

    Or am I missing something? Can I cash the credits before? That is, if I add 10 links to JDownloader that would require to have 100 credits to get automatically solved, can I solve 15 captchas, get 105 credits and then go to sleep, knowing that they will download automatically?

    1. KoalaBear said on August 19, 2011 at 9:37 pm

      Yes, that’s the idea. If you have enough credits for your downloads, all will be downloaded automagically. :)

    thanks for the link

    kept getting connection lost when trying to earn credits

  11. KoalaBear said on August 19, 2011 at 5:15 pm

    Well explained.

    Thanks for mentioning me. :)

    1. Martin Brinkmann said on August 19, 2011 at 5:16 pm

      I have to thank. This helps me a lot, as I can continue downloading while away or in fullscreen apps without that annoying display of the captcha.

      1. KoalaBear said on August 19, 2011 at 5:17 pm

        Very handy indeed :)
