Do I need to use JetBrains products to use Code With Me?

As a guest, you don't have to use a JetBrains IDE to access Code With Me. You can collaborate using a lightweight thin client that does not require installing an IDE.

To share a session as a host, you need one of the following IDEs: IntelliJ IDEA (Community or Ultimate), WebStorm, PyCharm, PhpStorm, GoLand, RubyMine, or CLion.
