 This is an easy-to-use wrapper for my commonly used [`zfit`](https://github.com/zfit/zfit) modules for simple binned and unbinned fits of distributions. `dist_fitter` is aiming to provide a `JSON` based IO format for quick fits with `zfit` with not much of the usually required lines of codes and handling of `zfit` classes.
