wtf is cozy-controller?

Cozy Controller is a tool that fetches and manages applications for the Cozy platform. Cozy itself is a personal cloud system you can install on your own hardware, letting you run web apps and connect your devices in a private space where no one tracks your activity. The controller acts as the background manager that keeps those apps organized and available. The platform treats apps as modules, and the controller handles the lifecycle work, fetching them, keeping them running, and managing updates. The README doesn't go into deep technical detail about the exact mechanism, but the gist is that it serves as the deployment layer between the Cozy platform and the individual apps you choose to install. This would appeal to someone setting up a self-hosted Cozy instance, say, a privacy-minded user who wants their own cloud instead of Google's or Apple's, or a small organization that wants to keep data in-house. Once Cozy is running on a server or personal machine, the controller works in the background so the user can install and manage apps without dealing with the plumbing. One notable detail is that the project is written in CoffeeScript, a language that compiles to JavaScript. The README also mentions that contributors could add support for Python apps, suggesting the system was primarily designed around JavaScript-based modules but was open to expanding beyond that.
