Upstash Vector
Ranked in Vector database hosting·Free plan·paid from $0.40/mo
About
Upstash Vector is a serverless cloud vector database for search workloads such as NLP, retrieval-augmented generation, recommendations, image recognition, clustering and classification. It exposes a REST API and SDKs, with first-class Python and TypeScript support and additional Go and PHP SDKs. Approximate nearest-neighbor queries use DiskANN; the product also lists FreshDiskANN as an index type. Similarity options include Euclidean distance, cosine similarity and dot product. Vectors can carry metadata, and filters can narrow queries using metadata expressions. Hybrid indexes combine dense semantic search with sparse exact-token search and fuse the results. Documented integrations include Vercel AI SDK, Flowise, LangChain, Langflow, LlamaIndex and LlamaParse. The Free plan is free and includes 10K daily queries/updates and up to 1 GB of data and metadata. Pay as You Go is 0.40 USD per month, billed per 100K requests, with storage at $0.25/GB and bandwidth free up to 200 GB/month, then $0.03/GB. Region availability varies by plan.
