IndexFlow

Overview

IndexFlow is an open-source **Rust** indexing infrastructure project introduced via Show HN around August 28, 2026, designed to power search and retrieval workloads for AI and traditional applications. It focuses on robust document ingestion, indexing, and query APIs that can be wired into RAG pipelines or custom search stacks. Developers should care because it offers a performant, language-agnostic core with HTTP/JSON APIs and a modern Rust codebase suitable for building scalable retrieval services.
