JetBrains is a company that provides IDEs for multiple different programming languages. Each of their IDEs cost about $150 every year and $600 every year for all products bundled together.
Using a "License Server," we can actually get all of these products for completely free using their legitimate applications. When you get any JetBrains product, find the Activation screen and select "License server". Then, for the address, use
http://188.8.131.52:81. Then, try activating. Done!
Please note that there is NO
/ at the end of the URL. If you do use one, it could fail to find the server.
