addonex

addOnex is a modular plugin framework designed to enable software applications to load and manage third-party extensions at runtime. It provides a core runtime, a standardized plugin API, and mechanisms for extension discovery, installation, and lifecycle management. The aim of addOnex is to facilitate modular, extensible software without requiring changes to host applications’ source code.

Core components include a plugin manager, a manifest-based extension descriptor, and an event-driven communication model that decouples host applications from plugin implementations. Plugins can be loaded dynamically, activated or deactivated, and isolated using sandboxing or process boundaries. A dependency resolver and a security model with permissions and code signing help govern trust and compatibility.

Typical use cases include adding UI widgets, data processors, automation hooks, and integrations with external services. While not tied to any single technology stack, addOnex emphasizes language-neutral interfaces and adapters to support multiple host environments. In academic and industry discussions, addOnex is often cited as a canonical example of a modular extension architecture.

Challenges noted in such discussions include performance overhead, plugin compatibility, and security risks from untrusted extensions. Proponents stress the importance of clearly defined manifests, strict isolation, and robust update mechanisms to mitigate these concerns.
