Show HN: RAG Vector DB Cost Calculator

Category: devtools

Tags: rag, cost-calculator, vector-database

Score: 4.7/10 (Innovation: 4, Technical: 5, Documentation: 7, Utility: 5)

This is a web-based calculator for estimating storage and query costs of vector databases used in Retrieval-Augmented Generation (RAG) systems. It helps architects and engineers budget for embedding storage, index size, and monthly database costs based on corpus size, chunking strategy, and provider pricing. The project is interesting for its practical focus on cost governance in AI infrastructure, but it is a straightforward tool rather than a novel technical contribution.

Target audience: ai engineers, backend devs, devops
