Retool recently published an endearing article about Yahoo Pipes, which reignited my nostalgia for a straightforward visual programming environment for data manipulation workflows. This led me to set up a server with n8n and FastAPI, utilizing an always-free E2 micro-instance on GCP.
I've been employing n8n for several personal AI projects. The community is brimming with ideas that could inspire you to experiment with it yourself.
If self-hosting n8n interests you, check out my GitHub repository where I've detailed setting it up for free on GCP.
