n8n is an open-source, low-code, self-hosted automation platform that allows non-programmers to automate tasks easily.
You can run n8n without installing by using the npx command or install it using npm or Docker for advanced users.
Creating a Discord webhook for a specific channel in a server is necessary for setting up notifications.
Configure nodes in n8n for notifications by adding Discord and HTTP Request nodes, and set messages to be sent for both platforms like Discord and ntfy for push notifications.
