The honest brief

Marqo

Bundles embedding generation, storage, and retrieval behind one API and can train a model on your own catalog — no separate embedding pipeline to wire up.

  • Generates and stores embeddings in-engine
  • Native multimodal (text + image) search
  • Turnkey ecommerce platform integrations
  • Backed by Lightspeed and Blackbird
  • Open-source engine is deprecated, no longer updated
  • No public pricing; commercial product is sales-led
  • Scope narrowed toward ecommerce search

Weaviate

Built-in vectorizer modules embed text inline — raw text in, vectors out — so you skip running a separate embedding pipeline.

  • Hybrid BM25 + vector search
  • Self-hostable or managed cloud
  • GraphQL and REST APIs
  • Resource-heavy at large scale
  • Module config has a learning curve
  • Managed tier costs add up
  • Newer than some lexical engines

When to pick which

Both cover Vector search, Embeddings, and Recommendation engine.

Pick Weaviate if you need RAG pipeline.

  • RAG pipeline (secondary capability)

Weaviate leans on Embeddings as a headline capability; Marqo treats it as secondary.
