PostgreSQL-native vector search via pgvector integrated into Supabase's managed backend — store embeddings alongside your relational data with auth, real-time subscriptions, and row-level security.
Supabase Vector is the vector search capability built into Supabase, the open-source Firebase alternative. Rather than being a standalone vector database, it leverages pgvector, the PostgreSQL extension for vector similarity search, integrated into Supabase's managed PostgreSQL infrastructure. This lets developers add vector search to applications that already use Supabase for authentication, storage, real-time subscriptions, and row-level security, without provisioning a separate vector service.
The core workflow involves enabling the pgvector extension on your Supabase PostgreSQL instance, creating tables with vector columns, and querying them using similarity functions (cosine distance, inner product, or L2 distance). Supabase wraps this with Edge Functions for embedding generation and database functions for similarity search. The match_documents pattern, a PostgreSQL function that takes a query embedding and returns the most similar rows, has become a widely-copied pattern in the RAG community.

Yes, Supabase Vector is good for ai memory & search work. Users particularly appreciate combines vector search with full postgresql capabilities: join embedding results with relational data, use transactions, and apply row-level security in the same query. However, keep in mind pgvector performance degrades beyond a few million vectors. dedicated vector databases like pinecone or qdrant significantly outperform at scale.
Yes, Supabase Vector offers a free tier. However, premium features unlock additional functionality for professional users.
Supabase Vector is best for Full-stack RAG applications on Supabase: Teams already using Supabase for auth, storage, and APIs who want to add semantic search without provisioning a separate vector database. One platform for the entire backend. and Multi-tenant AI applications with data isolation: SaaS platforms that need isolated vector search per tenant, leveraging PostgreSQL's row-level security to ensure each customer only searches their own embeddings.. It's particularly useful for ai memory & search professionals who need workflow runtime.
Popular Supabase Vector alternatives include Pinecone, Qdrant, Weaviate. Each has different strengths, so compare features and pricing to find the best fit.
