SyftHub

OpenMined
open source / Overall score: 1.5

Federated RAG framework from OpenMined. Rather than centralizing documents, a query is broadcast across a network of peers; each peer searches its own private index and returns only the most relevant snippets, which are aggregated, ranked and synthesized into a grounded answer. Its SDK loads data sources from the network, selects a model and runs the pipeline, built on OpenMined's Syft privacy stack.

Early-stage, created August 2025, and part of OpenMined's wider federated-RAG work.

SyftHub is open source: the SDK is Apache-2.0 with its source public, and the SyftBox network it runs on publishes its server code, so an operator can run the whole stack. The one closed piece is the OpenMined-run accounting service that bills paid services on the network, which free queries do not need.

Adoption

1 low confidence
1.0

SyftHub is a very early entry, part of OpenMined's federated-RAG effort alongside local-rag and local-rag-router, and its repository has attracted almost no attention yet. It is included here as an emerging project rather than for adoption to date.

Capability

2 medium confidence
2.0

SyftHub federates retrieval: each source is queried where it lives and only snippets leave it, which nothing else on the map does. The SDK leaves the federation itself to SyftBox, which users install separately, so it sits two steps below PySyft, the OpenMined runtime it builds on.
