What it is

The Application Engine for the AI Era, neo is a multi-threaded runtime with a persistent Scene Graph that allows AI agents to introspect and mutate applications in real-time. It's designed for developers building dynamic, intelligent applications.

neo stands out as a unique runtime environment specifically designed for AI-native applications, enabling developers to build highly interactive and adaptive systems where the application structure can be dynamically modified by AI agents in real-time.

When it fits — and when it doesn’t

A good fit for

  • Teams building highly interactive and adaptive web applications with AI-driven features

  • Developers who need a runtime that supports real-time application mutation by AI agents

  • Researchers working on AI-native applications where the application structure can be dynamically modified

Look elsewhere if

  • Projects requiring minimal setup or no self-hosting capabilities

  • Applications that do not require real-time interaction with an AI agent

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Steep learning curve for non-JavaScript developers

    neo's primary language is JavaScript, and its API heavily relies on JavaScript-specific patterns, making it challenging for developers unfamiliar with the language.

  2. 02

    Limited documentation and community support

    The official documentation lacks comprehensive guides and examples. The community is relatively small, leading to fewer resources and slower response times on forums and issues.

  3. 03

    Performance degradation with large-scale applications

    As the complexity of Scene Graph increases, neo's performance can suffer due to its real-time introspection and mutation capabilities, leading to potential bottlenecks in large-scale applications.

  4. 04

    Complex setup process for new projects

    Setting up a new project with neo involves multiple steps including configuration of the Scene Graph and integration with AI agents, which can be time-consuming and error-prone without detailed guidance.

What it does well

  • Multi-threaded runtime for high performance

  • Persistent Scene Graph for application introspection and mutation

  • Real-time AI agent interaction with the application structure
