n8n

n8n is a workflow automation tool for wiring APIs together with a visual node editor instead of writing a one-off integration script.

Runs in the n8n namespace behind Traefik on n8n.kei-space.com, with workflow and credential data stored in its own PostgreSQL database. One of its workflows also calls LiteLLM's in-cluster endpoint to generate embeddings.

A visual workflow tool makes multi-step automations easy to read and modify later, compared to a pile of small glue scripts.
