Teams switch for fully managed simplicity. Gain: zero ops, easier onboarding, consistent performance. Trade-off: cloud-only, more expensive, vendor lock-in. Pinecone is easier; Qdrant is cheaper and open-source.

Postgres teams switch to stay in existing stack. Gain: no new infrastructure, familiar tooling, simpler architecture. Trade-off: less specialized, not as fast as dedicated vector DBs at scale.

Teams switch for superior hybrid search and GraphQL API. Gain: best-in-class vector + BM25 hybrid, more flexible querying, knowledge graph features. Trade-off: slower at scale, higher memory usage.

Enterprises switch for massive scale. Gain: proven at billion+ vectors, strong community, Apache 2.0. Trade-off: more complex to operate, steeper learning curve than Qdrant.

Developers switch for embedded/local-first development. Gain: embedded mode, simple setup, great for prototyping and testing. Trade-off: less production-ready, smaller scale ceiling.
