I don't use any Jetbrains product and I have no idea how well-executed this is, but I am pleased to see a relatively smaller company competing against the almost monopoly of Microsoft's VS Code and GitHub.
Err, you're aware that GitLab is MIT and Space is not even pretending to be open, right?
IntelliJ and PyCharm Community are both Apache 2 licensed and are absolutely stellar <https://github.com/JetBrains/intellij-community> (I mean that they're not crippleware, they're outstanding products that just happen to omit Spring, SQL, and Django support from the Apache 2 versions)
