Choose rag-time if…

  • rag-time is primarily Jupyter Notebook; open-webui is Python.
  • License: rag-time is MIT, open-webui is Other.
  • Tags unique to rag-time: binary-quantization, generative-ai, gpt, azure.
  • Also covers Vector Databases.

When NOT to use rag-time

  • Last GitHub push was 389 days ago (dormant maintenance, Jun 17, 2025). Validate activity before betting a new project on rag-time.
  • LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
  • Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
  • Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
