### Observable calculator

State-of-the-art predictions for hundreds of observables, both in the Standard Model and for arbitrary new physics effects (parametrized as Wilson coefficients of dimension-6 operators above or below the electroweak scale)

### Likelihoods

Including a huge database of experimental measurement, flavio automatically constructs Likelihoods in parameter and Wilson coefficient space

### Plots

Visualize predictions or fit results in publication quality using flavio's predefined plot functions built on the power of matplotlib

### Easy to install

Thanks to Python, no compilation is necessary, even when you make changes to the code

### Easy to customize

By modifying simple text files, you can change input parameters or choose between different implementations, e.g. for hadronic form factors

### Interactive

Using Jupyter, you can access (or modify!) all the features of flavio in an interactive session (similar to Mathematica)
