  • Hybrid search improves recall on keyword-heavy queries
  • Same API whether you run it locally or in the cloud

Watch out for

  • Self-hosting means you own scaling and backups
  • Resource use is heavier than a minimal vector index
  • Module configuration adds concepts to learn up front

Which should you choose?

If your priority is local image generation, diffusion workflows, controlnet pipelines and reproducible generation graphs, ComfyUI is the stronger pick. If instead you care more about hybrid search, rag retrieval, self-hosted vector search, multi-tenant knowledge bases, go with Weaviate. For most people, trying both on a free tier is the fastest way to decide - they serve the same AI Models & Platforms space but differ in workflow and output style.
