n8n
n8n is an open-source, node-based workflow automation platform that lets you chain APIs, AI models, databases, and files into working pipelines — without writing a backend. Each "node" is a building block: an HTTP request, a code block, an AI call, an IF-branch, a file writer. Chains of nodes become workflows. n8n is the backbone of this entire course: you will connect PubMed APIs, call LLMs, parse XML, route messages via Mattermost, and build multi-stage research pipelines — all inside its visual canvas. Unlike tools that wrap AI features for non-technical users, n8n exposes the full plumbing: you see every API call, every error, every output. That transparency is deliberate — it trains real systems thinking. First released in 2019 by Jan Oberhauser; v1.0 in 2023; fair-code licensed (free self-host, cloud from $20/mo).
