I don’t really understand the term.
I got a survey about either getting gift card or a complimentary license for a SDK control set.
But I really wonder what’s complimentary license means?
I tried to search in their official site but didn’t say anything about it…
Is it last for the life and I can use the controls in all my personal software and publish it?

“Complimentary” means free of charge, i.e. for free. Whether that means “free for X days”, or “free for this version but not for any updates”, or “here’s a free product key that you can use just like a key bought for money” isn’t said. In general, companies only give away things for free if they think they will somehow get a net profit from it. Most normal products are given away for free in the hope that the user will like it and buy more; with SDKs, the marketshare among programmers is often quite valuable to the vendor, so it might actually be a completely free, unrestricted one. But it’s impossible to tell just from that phrase alone.

In short, that means free, aka without any charge like freeware or shareware.
Here is a reference information that states it in Wikipedia.
Many companies would often provide complementary goods and services
free of charge (i.e., on a complimentary basis). For example,
coffeehouses often provide Internet access free of charge to attract
more customers. Hotels often provide free shuttle services.
Restaurants often provide valet parking service free of charge.
