We’ve used nbdev for a wide range of software projects over the last three years, including deep learning libraries, API clients, Python language extensions, terminal user interfaces, and more. We discovered that it is not only capable of writing great software but that it has also increased our productivity by 300% or more. With nbdev, developers simply write notebooks with lightweight markup and get high-quality documentation, tests, continuous integration, and packaging for free! Nbdev has allowed us to maintain and scale manyopen source projects. Pull requests are often accompanied by detailed documentation and tests–contributors simply write notebooks.
