The author of this framework, who calls himself Kataras, is very unethical.
He fell into a big controversy with the management of his repositories, stealing several chunks of code from other popular projects without giving credits to their respective authors, and then using them to write benchmarks to make his own project look better than it is. He also spent several months creating bots to upvote his articles on different news aggregators and star his repositories to increase visibility in the GitHub Trending page. He also created several accounts in different websites (mostly Reddit) to act as a supporter of himself. The last time I heard about him, he had forked his own repositories multiple times to re-brand Iris with other names, hoping that people wouldn't notice, specially people who are just starting using Go.

One example, of many, https://github.com/avelino/awesome-go/pull/1137
It looks interesting, but appears to be an "all in" approach. I gather that folks who like Django may like this a lot, but for me personally it rubs me the wrong way.
This may be due to my "anti-framework" mindset, but in my experience a lot of other Go developers have this same mindset. YMMV
