It is basically a self hosted scraper and search engine in one. You give it your URL and some display templates and it indexes your site in much the same way Google normally would. The only difference is that the results are stored and served locally. They charge based on documents indexed. I don't think it would be good for storing arbitrary data like Solr, just web pages.
