Antfly

Antfly makes a self-hosted database that runs the whole retrieval pipeline inside one engine: chunking, embedding, indexing, and reranking happen as data arrives, and vector, keyword, and graph search are fused in a single query plan. Teams building AI applications and agents use it to ground responses in enterprise data without assembling separate vector stores, embedding APIs, and rerankers.

Antfly ships its embedding, reranking, and extraction models inside the engine, so no third-party API sees the data and nothing has to be deployed or tuned. The engine is free to download and self-host, with private managed instances offered through Antfly Cloud.
