I run an automation agency at orbiscr.com, and we use n8n for our projects. We create systems for others to use in their business automation rather than for our own use, and we use n8n to build these systems.
We primarily use n8n to create scrapers, website crawling tools, data collection systems from websites, and email automation, all integrated with different applications. I do not use it solo; I use it in combination with other technologies. We sometimes use it with a Python backend and partially with n8n. We call the backend through our architecture, for example, when we have a Python backend and a front-end with React, and then we have another backend with n8n, combining it with different usage patterns.
