Pros	Genuinely live indexing - documents update without rebuild jobs Self-hosted under BSL 1.1, no data leaves your infra Rich connector library (Kafka, S3, SharePoint, Postgres, Delta Lake) Same pipeline handles batch and streaming 20+ production-ready templates including multimodal and adaptive RAG	Object-storage-first architecture is dramatically cheaper than RAM-resident vector DBs at billion-vector scale Native hybrid search (vector + BM25) with metadata filters in a single query Namespace model plus copy-on-write branching maps cleanly to multi-tenant RAG and re-embedding workflows Very high write and query throughput demonstrated in production (10M+ writes/s, 25k+ QPS) Serverless — no clusters, shards, or replicas to manage; scales namespaces automatically Used in production by demanding AI teams (Cursor, Notion, Anthropic, Linear), which is meaningful social proof Comprehensive REST API and clear latency/recall SLIs published rather than hand-waved
Cons	Steeper learning curve than prompt-chain frameworks BSL is not OSI-approved - commercial restrictions apply at scale Smaller community than LangChain/LlamaIndex Pricing for Scale/Enterprise tiers not transparent	No free tier and a $16/mo floor even on the smallest plan, so it is not a fit for hobby projects or evaluation on a shoestring Closed-source, managed-only — no self-host option, which rules out air-gapped or fully sovereign deployments below the Enterprise BYOC tier Object-storage cold reads mean tail latency and cache-miss behaviour matter more than in a purely in-memory system; tuning matters for latency-critical UX You bring your own embeddings — no built-in embedding model, ingestion pipeline, or chunking, unlike higher-level RAG platforms Enterprise features people often need in regulated industries (SSO, HIPAA BAA, audit logs) start at the $256/mo Scale plan and above
