🧠Vector & Memory
Vector databases, KV/cache, and memory stores for RAG and agent state.
Machine board /api/leaderboards?category=vector-memory. Editorial 0–10, not Arena Elo. Alternatives for the current top row: /alternatives/supabase-pgvector.
Supabase (pgvector)
Depot default for most agent apps under ~25–50M vectors. Don't add Pinecone until Postgres actually hurts.
Qdrant
Depot pick for serious vector workloads with filters. Self-host or Cloud — either way you can leave.
Neon
Excellent serverless Postgres for agent apps that want branching + pgvector without Supabase's full BaaS.
Upstash Redis
Default serverless-edge-redis. Use classic Redis Cloud when you need always-on fat memory / Redis modules…
MotherDuck
Depot pick when the agent needs SQL warehouse context (analytics, DuckLake/Iceberg, shared Guides). Snowflake…
Voyage AI
Depot pick for RAG rerank. Keep Cohere as general embeddings default (enterprise + multilingual maturity)…
