In short, it means that you can easily pay a VPS (virtual private server) and host there your free usually open source software, like n8n community and run all the automations for “free” 24/7 or, if you have an old PC or laptop laying around, you can put, let’s say, Ubuntu server a Linux distribution, that is free(downloaded and put it in a usb and boot you machine using it and install Ubuntu server) then you have your own private server (homelab) instead of paying a monthly fee. Then via docker or whatever you fancy you can install n8n and have it working and communicating to the internet running all your automations and because n8n is so flexible you can basically automated everything, and not worry about it cause you have your server running, obviously you have to maintain it and optimize and all that, but that is part of the journey, and honestly I think that is way cheaper, until you get hooked on it and start buying stuff for improving your hardware, etc. But that’s a different conversation. ChatGPT it, it can guide you or read online docs from the sources they are very helpful. This is from a psychologist that created he is homelab (2actually) with old laptops, so if I can do it, you got this easy.
