There are some great Python REST frameworks out there, but we wanted something un-opinionated and easy to get started with but flexible enough to customise.
We’ve previously released our serialization/marshaling framework Kim (https://github.com/mikeywaites/kim), and Arrested includes built in integration for it. If you’d prefer to use another serializer, it’s easy to customise Arrested to do so and we’d love to receive a PR for it.
