vera-ai

Local code search combining BM25, vector similarity, and cross-encoder reranking. Parses 60+ languages with tree-sitter, runs entirely offline, and returns structured results with file paths, line ranges, and symbol metadata. Built in Rust.

qlever

Graph database implementing the RDF and SPARQL standards. Very fast and scales to more than a trillion triples on a single commodity machine

latence-solver

CPU-reference-first Tabu Search Quadratic Knapsack solver with optional accelerator hooks

voyager-index

Shard-first late-interaction retrieval for ColBERT and ColPali style workloads with CPU/GPU modes, Triton MaxSim, BM25 hybrid search, durable CRUD/WAL, multimodal preprocessing, and base64-ready reference APIs.

citrusdb

(distributed) vector database

colsearch

High-performance late-interaction retrieval engine for on-prem AI. ColBERT/ColPali multi-vector search with Rust fused MaxSim, Triton GPU kernels, ROQ quantization, LEMUR routing, WAL-backed CRUD, and a FastAPI server — single machine, CPU or GPU.

codexa

Codexa is a local semantic code intelligence CLI designed to help AI assistants and developers understand large codebases faster. It indexes repositories, parses code structure, generates embeddings, and enables powerful semantic search across functions, classes, and modules.

litepali

Lightweight ColPali-based retrieval for cloud

semantic-search

Make semantic search easier

ezra-search
