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.
- 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.
- 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.
- 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.
- 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
