The honest brief
Lantern
Adds production vector search inside Postgres itself — HNSW indexing and hybrid BM25 search with no separate vector store.
- Lives inside the Postgres you already run
- Open-source, self-host or managed cloud
- HNSW plus hybrid BM25 search
- Built-in embedding generation
- Tied to the Postgres ecosystem
- Smaller community than pgvector
- Managed cloud tier still maturing
Qdrant
Rust single-binary you can self-host, with payload filtering strong enough that teams pick it for metadata-heavy search.
- Open source, written in Rust
- Self-host or managed cloud
- Strong payload/metadata filtering
- Predictable latency at scale
- More ops than fully-managed rivals
- Smaller ecosystem than Pinecone
- Advanced features lean on managed cloud
