Flux0 is a powerful framework for building and deploying AI-powered applications. It helps developers manage the complexity of orchestrating AI agents, handling real-time communication, and integrating with LLMs and UIs — all in a unified, scalable way.
Flux0 simplifies:
- Deploying LangGraph, PydanticAI agents, or your own LLM logic.
- Building real-time streaming apps using JSON patch-based event streaming.
- Creating responsive user interfaces with our React toolkit
@flux0-ai/react.
Whether you're building a chatbot, agent system, or AI copilot — Flux0 provides the foundation.
Deploy and manage agents using frameworks like LangGraph, PydanticAI, or any custom logic — with no lock-in.
Built-in support for real-time streaming using JSON patches. Perfect for chat UIs, assistants, and continuous agent feedback.
Track, persist, and replay conversations with full context. Built-in session lifecycle management lets you build stateful experiences.
@flux0-ai/react helps you build conversational UIs that handle input, messages, system events, and streaming — with minimal setup.
Extend your app with custom workflows, event logic, or backend modules. Easily adapt Flux0 to your needs.
Building modern AI apps means combining many complex systems: LLM APIs, workflows, conversation state, streaming, and UIs. Flux0 unifies these pieces so you can:
- ✔ Focus on logic, not boilerplate
- ✔ Stream data in real-time by default
- ✔ Switch LLM frameworks or providers freely
- ✔ Use prebuilt UI components
- ✔ Prototype fast and scale cleanly
If you've ever struggled with:
- Coordinating multiple agents across sessions
- Persisting chat state across sessions
- Replaying and resuming conversations
- Handling streaming updates in UI
- Building robust, real-time conversational UIs
Then Flux0 is for you.
- AI Engineers who want a reliable backend for agents and workflows
- Full-Stack Developers building LLM-powered apps end-to-end
- Frontend Engineers who need real-time chat and event UIs
- Prototypers & Researchers testing new AI flows quickly
