The ability to have an open source solution, which is completely free for small teams or even individuals who are not looking at revenue generated by their software products! And also that it runs perfectly in cloud environments so there's no need to worry about servers running locally (which you do as well with other SaaS alternatives).
I like how easy-to use this service can be if one has some basic knowledge regarding Linux/Unix command line tools such as grep etc., but sometimes when doing something simple we tend just click around without knowing what exactly happens under hoods behind our eyes! This could possibly help people get familiarized better using CLI commands from time till times where they don't know much of them. It does seem very useful especially considering its price range compared against others out here nowadays. There really isn't anything bad i'd say aside maybe lacklustre support team response speed during non business hours -.
