Hey guys, I'm Leo - one of the founders of NStack.<p>We started work on NStack around a year ago, to help data-scientists productionise their models and compose them together with various data sources.<p>We built NStack using a mixture of low-level Linux technology, including systemd-containers, btrfs, dbus IPC, along with high-level concepts such as building a DSL, type-checker, and runtime. As a functional programming company, NStack is built using Haskell and are really excited to launch our CLI and server -- along with a sandboxed demo PaaS which you can try out now.<p>We'd love to hear any feedback.
