Pros
  • MIT-licensed and genuinely self-hostable, with a usable desktop build
  • Pluggable LLMs, embedders, and vector stores — no vendor lock-in
  • Built-in agents, API, and multi-user workspaces out of the box
  • Handles PDFs, Office docs, codebases, and websites without extra glue
  • True hybrid retrieval — BM25 + dense + sparse (ELSER) in one query with reranking
  • Filters, aggregations, geo, and time-series in the same index, so one cluster serves search + analytics + RAG
  • `semantic_text` field handles chunking and embedding calls automatically at ingest
  • Better Binary Quantization slashes vector RAM footprint dramatically for billion-scale corpora
  • Broad embedding-provider and framework support (OpenAI, Cohere, Bedrock, Vertex, LangChain, LlamaIndex)
  • Enterprise-grade RBAC, field/document-level security, and audit — rare among vector DBs
  • Open-source core with self-managed, cloud, and serverless deployment paths
Cons
  • Retrieval quality depends heavily on chosen embedder and chunking
  • UI and agent tooling lag behind dedicated commercial RAG platforms
  • Cloud pricing and quotas are less transparent than the OSS story
  • Steeper learning curve and operational overhead than purpose-built vector DBs like Pinecone or Qdrant
  • JVM cluster tuning (heap, shards, HNSW parameters) is non-trivial at scale
  • Cloud Hosted pricing is opaque compared to per-vector pricing of newer competitors
  • License change (Elastic License v2 / SSPL) blocks some managed-service resellers
  • Latency-sensitive pure-vector workloads can be beaten by specialised ANN-only engines
