Platform and SDK contracts

Use public contracts

Core is a private Nexia-operated runtime. Its repository is not available for developer cloning or redistribution. The public onboarding path is the CLI and cloud sandbox quickstart.

Develop your app against published SDK contracts. An App must not import Core internals or another App’s code. SDK documentation explains supported interfaces; it does not grant access to private package sources or introduce capabilities absent from your project.

Request a capability

If you need a new host capability, describe the business case, expected behavior, and smallest public contract at Developer Support. Do not attach Core source, credentials, or customer data. Nexia’s maintainers evaluate and implement host changes through the private development process.

The CLI alpha currently supports static app previews and review submission. It does not execute arbitrary server Functions or install a Composer App in a customer tenant.
