Viewflow is a low-code, reusable component library for creating comprehensive business applications with ease. Built on top of Django, Viewflow simplifies development by providing pre-built components for user management, workflows, and reporting, while still offering flexibility to customize and integrate with existing systems.

With Viewflow, you can create full-featured business applications in just a few lines of code using its reusable component library. It's shipped as a single package with batteries included, and each part of Viewflow can be used independently of the others, but they all work well together.

Viewflow comes in two flavors:

  • Viewflow Core: A lightweight, open-source library with only non-opinionated core classes that allows you to build your custom solution on top.
  • Viewflow PRO: A comprehensive package that includes reference functionality implementation and integrated with third-party Django packages. This package has a commercial-friendly license that allows private forks and modifications of Viewflow.



  • Modern, responsive user interface with an SPA-style look and feel
  • Reusable workflow library for quick implementation of BPMN workflows
  • Built-in customizable CRUD for managing complex forms and data
  • Integrated reporting dashboard
  • Small and concise API


Viewflow works with Python 3.8 or greater and Django 4.0+


pip install django-viewflow


pip install django-viewflow-pro  --extra-index-url<licence_id>/simple/

Add 'viewflow' and, in case you need workflow capabilities 'viewflow.workflow' to the INSTALLED_APPS


Quick start

Here's an example of how to create a simple pizza ordering workflow using Viewflow:

  1. Create a model to store process data

Before creating the workflow, you'll need to define a model to store the process data. Viewflow provides a Process model as the base model for your process instances. You can add your own fields to the model using jsonstore fields to avoid model inheritance and additional joins:

    from viewflow import jsonstore
    from viewflow.workflow.models import Process

    class PizzaOrder(Process):
        customer_name = jsonstore.CharField(max_length=250)
        address = jsonstore.TextField()
        toppings = jsonstore.TextField()
        tips_received = jsonstore.IntegerField(default=0)
        baking_time = jsonstore.IntegerField(default=10)

        class Meta:
            proxy = True
  1. Create a new flow definition file

Next, create a new flow definition file and define your workflow. In this example, we'll create a PizzaFlow class that inherits from flow.Flow. We'll define three steps in the workflow: start, bake, and deliver. We'll use CreateProcessView and UpdateProcessView to create and update the process data from PizzaOrder:

    from viewflow import this
    from viewflow.workflow import flow
    from viewflow.workflow.flow.views import CreateProcessView, UpdateProcessView
    from .models import PizzaOrder

    class PizzaFlow(flow.Flow):
        process_class = PizzaOrder

        start = flow.Start(
                fields=["customer_name", "address", "toppings"]

        bake = flow.View(

        deliver = flow.View(

        end = flow.End()
  1. Add the flow to your URL configuration:

Finally, add the PizzaFlow to your URL configuration. You can use the Site and FlowAppViewset classes to register your workflow with the pre-built frontend.

    from django.urls import path
    from viewflow.contrib.auth import AuthViewset
    from viewflow.urls import Application, Site
    from viewflow.workflow.flow import FlowAppViewset
    from my_pizza.flows import PizzaFlow

    site = Site(
        title="Pizza Flow Demo",
            FlowAppViewset(PizzaFlow, icon="local_pizza"),

    urlpatterns = [
        path("accounts/", AuthViewset().urls),
        path("", site.urls),
  1. Make and run migrations and access the workflow through the pre-built frontend.

Make and run migrations to create the necessary database tables, then start your Django server and access the workflow through the pre-built frontend. You should be able to create and track pizza orders with the workflow.
