- Minimal permissions with website access requested only when an Activity needs it
- Discord integration through the official local RPC interface
- Cross-platform Desktop support for Windows and Linux, with macOS planned
- Developer-friendly Activity API built with TypeScript
- Lightweight native Desktop application written in Rust

Activities are maintained separately from the core Parousia repository and use a shared Activity API.
Activities are organized by website and can provide their own settings, page data requirements, site access, Discord applications, and Rich Presence details.
Parousia currently includes the native Activity ecosystem alongside a large selection of compatible PreMiD Activities.
Full documentation covering installation, configuration, Activities, compatibility, privacy, security, and development is available at:
