For those who -like us- has several restrictions moving data out of our servers, here in our lab we have develop a tool called qiime_2_ll_quick_viewer which you can use to open your Qiime 2 visualization artifacts (*.qzv) in situ.
It sounds like that definitely stops you from using qiime tools view and view.qiime2.org since you wouldn't be able to download it to your PC or make a link from it.
Perhaps the ability to start a server on a port could make it into qiime tools view someday to suite your use-case better!
While I know this isn't what you are talking about, I do want to take a moment to emphasize for anyone else reading (since this is often a point of confusion) that view.qiime2.orgnever sends your data anywhere. We honestly couldn't afford the bandwidth, so that site is more of a super-easy to install program that happens to run in your browser.
And by "anywhere," we mean your data doesn't leave the computer that you are loading https://view.qiime2.org on!
If you are interested in how we make that happen, please check out this presentation from earlier this year:
In this talk I go into a little bit of detail regarding q2view (the application behind the scenes for the serverless view.qiime2.org), as well as some other high-level details about QIIME 2. Thanks!
