Qiita (canonically pronounced cheetah) is a meta-analysis environment for microbiome (and other "comparative -omics") datasets. You can find the public Qiita server at qiita.microbio.me.
Qiita is currently in pre-alpha status. We are very open to community contributions and feedback. If you're interested in contributing to Qiita, see CONTRIBUTING.md. If you'd like to report bugs or request features, you can do that in the Qiita issue tracker.
To install and configure your own Qiita server, see INSTALL.md.
