Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Examples of Microkernels?
It seemed to be in a similar space to Genode when I had a brief look. Is it clear how it compares?
A system that claims to allow you to configure it in microkernel and other modes might be interesting for comparison of the approaches, but I've only noticed it via a local connexion: https://project-flexos.github.io/

Unikraft is a fast, secure and open-source Unikernel Development Kit
Thanks for the feedback, we're in the process of adding a security section[0] which will detail more on the on-goings, but we'll work on adding more highlights on the main page.
I need to highlight we have separate research[1][2] which will make its way upstream soon which aims to provide hardening between internal libraries (e.g. isolating the network stack or scheduler) using gates like Intel MPK or separate hardware-accelerated services.

Unikraft is a fast, secure and open-source Unikernel Development Kit
1. We build unikernels using the 'kraft container' which is Docker/OCI image[0][1] which has the necessary build tools to build Unikraft unikernels. We plug this into Concourse which builds thousands of combinations of Unikernels[2] as part of our code review process[3]. In addition to this, we have on-going research and tooling to help automatically discover permutations of Unikernel builds[4].
2. Really great question, but mostly you can expect the same functionality of an application when it runs as a unikernel because the application "thinks" it's still running in a traditional OS environment -- as it should be. Check out this documentation[5] (after step 7) about porting, it has snippets about where the boundary sometimes breaks.
3. Well, general-purposes are not suited for deployment environments. Installing Gentoo (or Ubuntu, Debian, for that matter) is a waste of resources if you only SSH in once to install your desired application.
