Just build IHaskell or use the docker container. Kronos is by the author of IHaskell and if I recall also had a repo for a node-webkit wrapper around IHaskell or IPython which this appears to be the continuation of.
To add: Building and installing IHaskell (on Mac at least) is a bit of a hassle if you just want to get up and running. You need XQuartz, cairo for the Diagrams module, gcc, a non-distribution ipython (recommended), and of course a sane cabal environment. If you know what you're doing, that's a few minutes in shell commands, making sure you're in a sandbox, etc. If you're new to all of this, have fun figuring out why your build keeps exiting because of some weird ABI breakage in an upstream Haskell package, or setting the right library paths so that GCC can do its job, or finally getting everything to build after GHC takes a week off in the Bahamas only to find that the kernel dies immediately... (https://github.com/gibiansky/IHaskell/issues/287 now fixed, don't worry!)
Despite that, it's a great tool and without it I don't think I would have been as motivated to work through the stack of Haskell learning materials I've got piling up.
Edit: Based on the author's comment above (PieSquared) Kronos is deprecated with IPython 2, so it must be what I was thinking of regarding the older repo.
