Today's RAG & Vector Databases: Fastest-Growing Projects — October 28, 2026

Today's the RAG & Vector Databases space, we see a continued trend towards sophisticated compositional frameworks and advanced graph-based databases. These developments are driven by an increasing demand for more robust and flexible solutions in handling complex data interactions and retrieval systems. The tools highlighted this week range from a novel framework that explores the compositionality of RAG pipelines to a hypergraph database designed for higher-order interactions.

dolev31/lasagna
Lasagna is a comprehensive framework that evaluates different configurations of RAG (Retrieval-Augmented Generation) pipeline stages, aiming to understand how changes in one stage affect overall performance. The project has garnered significant attention with 21 stars and demonstrates active development with 100 commits over the last month.
The growth score of 45.21 suggests a substantial interest from developers who are looking for systematic ways to improve their RAG systems through rigorous testing and optimization.

metacoglabs/hypergraph
Hypergraph is a native vector-hypergraph database that supports persistent storage, enabling it to handle higher-order interactions more effectively than traditional graph databases. With 26 stars, this project shows steady development with regular commits over the past month.
The growth score of 13.23 indicates moderate interest from developers interested in leveraging advanced data structures for complex relational data.

ronitgupta138/vectra-core
Vectra Core is an in-memory vector search engine that provides sub-millisecond KNN (K-Nearest Neighbors) retrieval, optimized with 8-bit scalar quantization and high query per second performance. It has attracted a significant following with 64 stars.
Despite having fewer recent commits compared to some other projects on this list, its substantial star count suggests it meets the needs of developers looking for extremely fast in-memory vector search capabilities.

OceanOver/Tomechat
Tomechat is an RAG knowledge-base chat application built using LangChain, featuring FAISS vector search and a FastAPI backend. It also includes a Next.js web UI and supports OpenAI and Gemini APIs.
With 22 stars and limited recent activity (only five commits in the last month), its growth score of 1.52 reflects a niche interest from developers working on RAG-based chat applications that integrate with multiple AI platforms.

In summary, Today's report highlights projects that cater to different aspects of advanced data retrieval and interaction within the RAG & Vector Databases space. From comprehensive framework evaluations to specialized vector-hypergraph databases and efficient in-memory search engines, these tools are making strides in their respective areas by addressing specific developer needs and gaining traction through active community engagement.
