KDevelop – A cross-platform IDE for C, C++, Python, QML/JavaScript and PHP

However, it's hard for me to choose KDevelop for serious development. As long as it doesn't have feature parity with JetBrains products, I cannot recommend it. Hard to get there since JetBrains R&D budget most likely exceeds KDevelop by a great margin.
I'm using it. It's ok, but missing xdebug support. I prefer it because don't like Java and browsers based IDEs.
Maybe it's time for me to try it again, but for C++ work I currently use clion. KDevelop is a beautiful app and I really wish it hit the right notes for me, but it always just barely misses.
