Neuron Ai

Neuron is a PHP framework for building agentic applications. It handles the plumbing of working with language models, including provider orchestration, memory, streaming, structured output, monitoring and debugging, so developers can concentrate on what their agents actually do. It runs inside an ordinary PHP codebase and can grow from a single agent to a multi agent system. The documentation covers agents, messages, tools and toolkits with approval steps, chat history and memory, MCP support, middleware, error handling, evaluations and testing. A common interface for providers lets developers swap between Anthropic, OpenAI, Gemini, Mistral and Ollama without rewriting application code, and the same modular design applies to embeddings, vector stores and memory backends. Retrieval augmented generation is supported with data loaders, pre and post processors and retrieval components, alongside audio, image and classifier capabilities. A workflow engine handles single step and multi step flows with loops, branches, state, interruption, persistence and streaming. The framework is aimed at PHP developers who want to add agents to existing web applications rather than move to another language. The docs also include a ready made prompt for pointing a coding agent at the installation, a video tutorial series and a companion community hub. The documentation site publishes no price for the framework or any paid tier.
