Gramps Web backend development
The backend of Gramps Web is called Gramps Web API. In fact it is more than just an app backend: it provides a RESTful API to read and modify a Gramps database.
Gramps Web API is a Python application and is powered by the
gramps library itself (which also powers the Gramps Desktop application).
In this section of the docs, you can learn how to contribute to Gramps Web API development.
