There is no "free" version, only a "if you make less than $X" version, which is a huge red flag for me.
Lazarus is free, but due to the way their help files are build, incremental improvements in it are impossible, so it's just a list of arguments for functions, with no real explanations.
Ah, interesting. $5000 isn’t a lot for professional software developers but could be fine for hobby projects I guess. $1300 for the professional version is a steep price jump from $0
