The [django-rest-marshmallow][django-rest-marshmallow] package provides an alternative implementation for serializers, using the python [marshmallow][marshmallow] library. It exposes the same API as the REST framework serializers, and can be used as a drop-in replacement in some use-cases.

The [serpy][serpy] package is an alternative implementation for serializers that is built for speed. [Serpy][serpy] serializes complex datatypes to simple native types. The native types can be easily converted to JSON or any other format needed.

The [dynamic-rest][dynamic-rest] package extends the ModelSerializer and ModelViewSet interfaces, adding API query parameters for filtering, sorting, and including / excluding all fields and relationships defined by your serializers.

The [html-json-forms][html-json-forms] package provides an algorithm and serializer for processing `<form>` submissions per the (inactive) [HTML JSON Form specification][json-form-spec]. The serializer facilitates processing of arbitrarily nested JSON structures within HTML. For example, `<input name="items[0][id]" value="5">` will be interpreted as `{"items": [{"id": "5"}]}`.
