## Polygres

Polygres is a retrieval platform that treats PostgreSQL as the backbone for AI-native applications. Rather than forcing teams to migrate to a new vector-only database, it virtualises a GraphRAG-style retrieval layer on top of Postgres, so existing relational records, embeddings and text indexes stay where they are while agents gain the ability to search by meaning, follow relationships and match exact wording in one request.

The platform bundles four complementary retrieval modes: semantic vector search for meaning, graph traversal for multi-hop relationships and shortest-path style queries, full-text search for exact terms, and hybrid search that blends them. Developers reach these capabilities through a hosted playground, a CLI for managing projects and imports, and a typed Python SDK for production applications.

Behind the managed platform are two open-source engines, pgGraph for graph traversal inside Postgres and pgContext for AI search, which teams can inspect, benchmark and self-host. Polygres supports both a managed database hosted by the company and connecting an existing Postgres instance, and it markets itself around agent memory, grounded answers with sources, product semantic search and recommendation systems.

**Pricing & Plans:** Polygres follows a freemium model with a free tier for getting started and paid managed plans for production workloads. Exact tiers are published on the company's pricing page, so check there for current numbers before budgeting.

- **Unified retrieval API:** Query graph, vector, full-text and hybrid retrieval through one consistent interface instead of stitching multiple systems together.
- **Graph traversal on Postgres:** The open-source pgGraph engine follows relationships across your records, enabling multi-hop and shortest-path retrieval without moving data.
- **Vector and hybrid search:** Semantic search over embeddings combines with sparse and full-text matching so queries that mix meaning and exact terms still work.
- **Developer toolkit:** A dashboard playground, CLI for imports and configuration, and a typed Python SDK make it straightforward to prototype and then ship.
- **Managed or bring-your-own Postgres:** Start on a Polygres-hosted database or connect an existing Postgres instance and extend what you already run.

**Strengths:** Keeps your existing PostgreSQL instead of forcing a migration to a specialised vector store; Combines four retrieval modes in one platform, which reduces the number of moving parts in a RAG stack; Core engines pgGraph and pgContext are open source, so the internals are inspectable and self-hostable; Familiar Postgres tooling, SQL knowledge and connection patterns carry over for most teams

**Limitations:** Team and community are relatively early-stage, so long-term support and ecosystem maturity are still developing; Being a newer product, third-party tutorials and integrations are thinner than for established vector databases; Fully managed convenience depends on using the hosted offering rather than the open-source engines alone

## Qdrant

Qdrant is an open-source vector database and similarity search engine written in Rust. It stores vectors alongside JSON metadata and answers nearest-neighbor queries so applications can retrieve relevant items by meaning rather than exact keywords. The engine includes a custom storage layer (Gridstore), real-time indexing without full rebuilds, and quantization techniques that reduce memory use dramatically for large collections.

For retrieval quality, Qdrant supports native hybrid search that blends dense and sparse vectors in a single query — with BM25, SPLADE++ and miniCOIL — plus multivector storage, one-stage filtering during HNSW traversal, and reranking options such as score boosting, ColBERT-style late interaction and MMR diversification. Common applications include RAG and GenAI pipelines, AI agents with persistent memory, semantic search, recommendation systems, and anomaly detection.

Deployment is flexible: run the open-source engine yourself, or use Qdrant Cloud (managed, usage-based, on AWS, GCP or Azure), Hybrid Cloud (managed clusters in your own Kubernetes), Private Cloud (air-gapped and compliant setups) or the newer Qdrant Edge for low-latency local search. Free-tier cloud clusters, SOC 2 and HIPAA aligned posture, and enterprise tooling like SSO, RBAC and Prometheus/Grafana integrations make it suitable for both prototypes and production.

**Pricing & Plans:** The open-source engine is free to self-host. Qdrant Cloud offers a free-forever tier (single node, 0.5 vCPU / 1GB RAM / 4GB disk), usage-based Standard pricing for production (compute, memory, storage plus paid inference tokens), and sales-led Premium, Hybrid and Private Cloud plans.

- **High-performance vector engine:** Built entirely in Rust with SIMD and a custom Gridstore storage engine for fast, scalable vector search.
- **Native hybrid search:** Combine dense and sparse vectors in one query, supporting BM25, SPLADE++ and miniCOIL for keyword-plus-vector retrieval.
- **Expansive metadata filtering:** Store metadata as JSON and apply advanced filters such as nested, text, geo and has_vector, with filters applied during HNSW traversal.
- **Memory-efficient quantization:** Asymmetric, scalar and binary quantization reduce memory usage by up to 64x while preserving search quality.
- **Developer-friendly APIs and Web UI:** Use REST, gRPC or official clients (Python, JavaScript and more), a built-in Web UI, and native cloud inference for text and image embeddings.

**Strengths:** Open-source core with a generous free cloud tier for prototyping; Strong performance and Rust-based engineering trusted by 35k+ GitHub stars; Native hybrid search and one-stage filtering simplify production retrieval; Deploy anywhere: cloud, hybrid, private or edge, plus SOC 2, HIPAA, SSO and RBAC tooling

**Limitations:** Requires engineering effort to set up and operate compared with turnkey managed services; Advanced capabilities like quantization, hybrid search and multivector retrieval assume solid technical understanding; Premium and private cloud tiers are sales-led with no published price list
