App Preference Features

What’s an “App” in Riff?

An app is a contained project with a frontend (UI) and a backend (APIs, jobs). The agent plans, edits code, runs, and deploys this app inside a single workspace.

• Frontend: pages, components, copy, and styles the agent can generate or modify.

• Backend: API routes, data access, integrations, schedules, and background work.

Think of App Preferences as the “operating brief” the agent reads before it plans and writes code for this app.

What are App Preferences?

App Preferences are high-level settings that tell the agent how to approach work in this specific app. They don’t change production by themselves -they guide the agent’s planning and execution when you ask it to build, fix, or enhance something.
