About Bruno
Bruno is a lightweight, open source API client and IDE for exploring and testing APIs, built for developers and teams who want their request collections stored as plain text in a folder on their own filesystem rather than in a vendor's cloud.

About django-ninja
Django Ninja is a web framework for building APIs with Django and Python 3.6+ type hints. It lives in the Python ecosystem and the Django ecosystem specifically, and it is distributed under the MIT license. The framework is designed around type hints, Pydantic, and async support, and it generates API schemas from the open standards for APIs: OpenAPI (previously known as Swagger) and JSON Schema. A NinjaAPI instance is declared next to the existing Django url configuration and mounted as a normal URL pattern, so the project sits alongside Django rather than replacing any part of it.
