Flux0

Flux0 is an open-source framework designed to enhance LLM-based agents with real-time streaming, multi-agent orchestration, session management, event streaming, and LLM-agnostic integration. Unlike frameworks that aim to replace existing tools, Flux0 is built to complement frameworks like LangChain, LangGraph, and PydanticAI. It allows developers to focus on their agent logic using their preferred LLM framework while Flux0 handles the surrounding infrastructure. Key features include real-time UI updates with JSONPatch over SSE, agent/session models for managing context, event streaming and persistent memory, pluggable storage, and async background execution. Flux0 was developed to be developer-friendly and production-ready, offering flexibility to integrate into any stack. It is particularly useful for those building AI assistants, copilots, or agent-like systems who seek full control over their architecture.
