jtoh89/n8n-master ? reverse-engineered prompt

Build me a self hosted workflow automation app like n8n, where I can connect different services together and automate repetitive tasks without writing much code.

I want a web app with a visual, node based editor so I can drag together steps, connect apps, and run workflows from a browser. It should let me create, edit, save, and test workflows, then see what happened when they run. Make it easy to add lots of integrations, and leave room for custom logic so I can plug in my own functions or connect to other tools later.

It should be something I can run locally or in Docker, with a clean setup and a nice interface at localhost. If you need to look up current docs online while building it, go ahead. Please make it feel polished and practical, like a real product someone could use to automate work across different services.
