Introduction
Your next application will be agentic. Build it with the technology you love.
What is Neuron
Neuron is a PHP framework for developing agentic applications. By handling the heavy lifting of providers orchestration, memory management, UI integration, and debugging, Neuron clears the path for you to focus on the creative soul of your project. From the first line of code to a fully orchestrated multi-agent system, you have the freedom to build AI entities that think and act exactly how you envision them.
We provide tools for the entire agentic application development lifecycle, from LLM interfaces, to data loading, to multi-agent orchestration, to monitoring and debugging. In addition, we provide tutorials and other educational content to help you get started using AI Agents in your projects.

Support For Multiple Providers
Neuron uses a common interface for LLM providers (AIProviderInterface) as well as for the other components, such as memory, embedding, vector stores, toolkits, etc. The modular architecture allows you to swap components as needed, whether you're changing LLM provider, adjusting memory backends, or scaling across multiple servers.
Here are a couple of examples:

Why Neuron
Your next application will be agentic. A growing share of new software is no longer a web application with AI features added along the way, but an application born agentic, where the agent is the architecture itself, driving how the system reasons, acts, and talks to the user interface. Building this kind of application requires a specific set of foundations: event-driven workflows with checkpointing, human-in-the-loop, interruption, multi-agent orchestration, streaming, and agentic UI protocols like AG-UI and the Vercel AI SDK protocol, MCP, and asynchronous execution.
In the PHP ecosystem, this set of foundations exists in one place. Each one is a chapter of this documentation: Workflow, Human in the loop, Streaming & UI protocols, MCP, Async, Middleware, Evals.
There is also no second framework waiting for you when the project grows. The same Workflow that runs your first agent in the getting started guide runs a multi-agent system with state, loops, and human approvals in production. What you learn on day one is what you ship in future projects.
A Vertical & Independent Ecosystem
Neuron is also the only vertical ecosystem for agentic applications development in PHP. Around the framework there is a registry of extensions, tools, and technologies designed specifically for agentic applications, and a growing number of companies building on the same architecture instead of assembling their own from scattered parts.
For a software house, this is a place to be recognized as a specialist rather than one more team claiming AI experience. For a company that needs an agentic foundation it can commit to for years, it means standardizing on an architecture whose whole direction is this space, not a general-purpose library where agents are a side feature.

E-Book - "Start With AI Agents In PHP"
The gap between modern agentic technologies and traditional PHP development has been widening in recent years. While Python developers enjoy a wealth of libraries and frameworks to create AI Agents, PHP developers have often been left wondering how they can participate in this technological revolution without completely retooling their skillsets or rebuilding their applications from scratch.
Neuron changes all that.
This book serves as both an introduction to AI Agents concepts for developers and a comprehensive guide to Neuron framework.

Last updated
You are going to set up Neuron AI, a PHP framework for building agentic applications,
in this project, and you must follow three steps in order.
- First: install the framework: check composer.json, and if neuron-core/neuron-ai is not
already required, run `composer require neuron-core/neuron-ai`;
- Second: install the agent skills that ship
with the package by running `npx --yes skills add ./vendor/neuron-core/neuron-ai/skills -y` from
the project root. Add this command to `post-update-cmd` in the composer.json file, so they
stay updated whenever Neuron is updated through Composer. From then on, load the relevant
skill before you write any Neuron code instead of relying on what you remember about
the framework;
- Third: work out what kind of app this is. Look at composer.json
and the project structure to tell whether it is a Laravel app or a Symfony app, then
activate the matching skill: neuron-laravel-integration or neuron-symfony-integration.
If Neuron is already part of the app go through the skill's foundations checklist
item by item. Report what differs from the recommended setup;
If Neuron is not in the app yet, follow the same checklist to do the first setup.
If the app uses neither framework, start from a plain PHP agent using
the neuron-agent skill. Finish with a short summary of what you installed
and what you found.namespace App\Neuron;
