# Neo.mjs: The Application Engine for the AI Era

> Neo.mjs is not a framework, but a multi-threaded Application Engine for the web.
> It moves all application logic, state management, and data processing off the main thread,
> ensuring a desktop-class, jank-free user experience.

> **Key Capabilities:**
> * **True Multithreading:** 100% of your code runs in a Worker, keeping the UI thread free.
> * **The Neural Link:** A bi-directional bridge allowing AI agents to inspect and mutate the live Scene Graph.
> * **Object Permanence:** Components are persistent objects that can move between browser windows without losing state.
> * **Zero Build Step:** Runs natively in the browser as ES Modules (no transpilation).

> **AI-Native Architecture:**
> Neo.mjs is the first platform architected for "Context Engineering." It includes dedicated
> MCP Servers (Knowledge Base, Memory Core) that allow AI agents to act as co-developers.

Neo.mjs uniquely deploys each application and example in four equivalent environments.
The URLs listed below use the **development mode** paths (Zero Build), which embody the core philosophy.
To access bundled versions, prefix paths with `/dist/production/`, `/dist/development/`, or `/dist/esm/`.
