ApuOS separates the system host from optional applications. The Package center provides signed host-compatible modules; the Application center provides templates and metadata while the NAS downloads container images from the selected registry.
Check architecture, host version, memory, storage, ports, permissions and the application's own license. A catalog entry is not a promise that every device can run the application. The NAS verifies signatures, hashes and compatibility before installation.
AI capabilities include model connections, local model runtimes, speech/OCR, knowledge retrieval, gateways, agents and automation. Each capability has its own model, runtime, resource and credential requirements. See AI applications for the current boundaries.
The server stores catalog metadata and templates; it does not mirror every Docker image. The NAS pulls images directly from the reviewed registry and keeps installation data, credentials and container state locally.
