Upstash Vector

Serverless vector DB, per request

Free tier + paidSearch, vector & RAGupstash.com

What it is

An HTTP-first vector database billed per request, with no cluster to provision and true scale-to-zero. Because it speaks REST rather than a persistent socket, it works from edge runtimes and serverless functions where connection pooling is painful. Hosted embedding models let you upsert raw text.

Why it earns a slot

The right shape for a hobby project that sits idle for weeks — you pay nothing while nothing happens. Calls work directly from Cloudflare Workers and Vercel Edge functions.

Know before you commit

The free tier caps vectors at 1,536 dimensions, so larger embedding models force a paid plan. Per-request billing punishes chatty multi-query retrieval loops.
