The setup includes Ollama for local LLM execution, Qdrant for vector search, MongoDB for document storage, Redis for caching, Neo4j for knowledge graphs, Keycloak for authentication, and n8n for workflow automation. The stack can be configured for CPU-only, GPU-accelerated, or external API usage, with automated setup scripts that handle dependencies and provide instant access to all services. Neo4j integration enables advanced relationship mapping between documents and entities, enriching context beyond traditional vector search. 15 [See all Faun archives](/sources/faun/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/faun/best-of/2025/10#page","url":"https://daily.dev/sources/faun/best-of/2025/10","name":"Best Faun Posts — October 2025","description":"The most upvoted Faun posts from October 2025, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/faun/best-of/2025/10#items","numberOfItems":4,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/my-n8n-journey-from-zero-to-building-ai-powered-tools-kccvipxkd","name":"My n8n Journey: From Zero to Building AI-Powered Tools"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/my-kubestronaut-journey-1dsu6o4kg","name":"My Kubestronaut journey"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/owasp-top-10-for-appliction-programming-interfaces-ban8en5cg","name":"OWASP Top 10 for Appliction Programming Interfaces"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/deploying-a-complete-rag-ecosystem-with-a-single-command-my-ultimate-docker-stack-jewsgwbfw","name":"Deploying a Complete RAG Ecosystem with a Single Command: My Ultimate Docker Stack"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Faun","item":"https://daily.dev/sources/faun"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/faun/best-of"},{"@type":"ListItem","position":5,"name":"October 2025"}]}]} ```
