Replacements
Listings that take over the same core job as RAGFlow.

PrivateGPT is a developer-focused API layer for document question answering on local models, with MCP and text-to-SQL support, but no visual agent builder and a separate inference server.
AnythingLLM
A desktop AI app that answers questions about your own documents, with no account and no API key needed.
AnythingLLM is an MIT-licensed desktop app for Windows, macOS and Linux that bundles document chat for individuals, instead of a team-oriented server deployment.
Open WebUI
A self-hosted chat interface that talks to Ollama and any OpenAI-compatible API, so your local models get a proper front end.
Open WebUI is a multi-user self-hosted chat interface with document retrieval, focused on chatting with Ollama and OpenAI-compatible models rather than on ingestion pipelines.
Khoj
Open-source AI second brain that researches across your documents and the web with any model.
Khoj is an AGPL-3.0 self-hostable assistant grounded in your notes and files that also searches the web, oriented to individuals more than organisations.
