Blue Card isn't only option. For example, in Sweden there are two work visas for software developers: Blue Card and Work Permit.

I didn't get Blue Card since I didn't get job offer with really high salary, but instead I got Work Permit which don't require salary 1.5 times higher than the average.

Also in Netherlands there are two options: Blue Card and High Skilled Migrant.

Requirements for High Skilled Migrant are much lower than for Blue Card.

In Sweden and Netherlands you can work without university degree.

In Germany, you can not get Blue Card without university degree. And if you want to get Work Permit as alternative, you should know German language (Sweden and Netherlands don't require you to know their language).

So Germany isn't good option. I recommend Sweden and Netherlands if you don't have university degree.
