Show HN: Dcup – 100% Open-Source RAG-as-a-Service for AI-Powered Search

3 aliamer99 0 5/2/2025, 7:38:13 AM dcup.dev ↗

Dcup is an open-source RAG-as-a-Service that turns your documents into a self-hostable, extensible AI-powered search engine. Connect AWS S3, Google Drive, Dropbox, or direct uploads, then chunk, embed, and index every file in Qdrant. Leverage hybrid semantic+keyword search, optional re-ranking, and lightning-fast OpenAI responses. I believe any tool that works with data should be fully open source—Dcup gives you full control without black boxes or vendor lock-in.
