Term	Meaning
App	One product you build and publish on Stardeck, with its own code repository. The dashboard sometimes calls it a project.
Branch	A separate line of work on an app, with its own sandbox and preview, that doesn't touch the live app until it's merged. See Feature Branches.
Business type	The kind of business an app is set up for, such as Restaurant or café or Spa or salon. It switches some features off and renames pages. See Modules.
Coding agent	An AI agent on your computer, such as Claude Code, Codex or Cursor, that writes your app's code and reaches Stardeck over MCP. See Quickstart.
Customer agent	A Starcat agent that answers your customers on LINE, Facebook, Instagram or your website. See Customer Agents.
Data store	A database for an app's records, such as orders, bookings and customers. You choose which of its branches each environment uses. See Data Stores.
Deployment	A running copy of an app in one environment.
Developer mode	An organization setting in Settings → General that shows the app-building tools: code, previews, sandboxes and developer settings. Anyone can keep it on for themselves under Preferences.
Environment	Where a copy of the app runs: sandbox, preview, staging or production. See Environments.
Environment variable	A setting the app reads when it runs, such as an API key, set per environment. See Environment Variables.
Features in use	The page in an app's own admin where the business owner turns features on and off for staff. See Modules.
Graviton	The code-level rules for a Stardeck app: its SDKs, file layout and constraints. Only developers need it. See Building on Graviton.
Knowledge store	Your organization's shared documents and policies, which Starcat reads before answering. See Starcat.
Library Module	One of five always-on Modules that every feature Module builds on, such as formatting and the UI kit. They have no screens. See Library Modules.
MCP	Model Context Protocol, the standard that lets a coding agent such as Claude Code use Stardeck's tools. See AI Integrations.
Module	A feature Stardeck builds and maintains, such as POS or Booking, that ships inside every app. See Modules.
Organization	Your company's account on Stardeck. Its members, apps and billing belong to it. See Members & Roles.
Preview	A deployment of a branch at its own link, for sharing work before it goes live. See Sandbox & Preview.
Production	The live app your customers use, at `your-slug.stardeck.site` or your own domain. See Publishing & Deployment.
Publish	Deploy the app to production.
Sandbox	The private, non-live copy of an app for building and testing. An app you run on your computer reads the sandbox's data, and Starcat Developer works in the sandbox in the cloud. A new app's sandbox shares production's data until you split them. See Sandbox & Preview.
Skill	A saved set of instructions an agent follows to do a job the same way each time. See Skills.
Slug	The short name in an app's address: the `lamp-coffee` in `lamp-coffee.stardeck.site`. You choose it when you create the app.
Staging	A 24-hour copy of the app on a fresh copy of production data, for testing against real records. See Staging.
Stardeck CLI	The `@stardeckai/cli` command that creates apps, connects your coding agent, pulls the local environment and deploys. See Quickstart.
Stardeck Edge	A small machine at your location that connects the app to receipt printers, cash drawers and customer displays. See Stardeck Edge.
Starcat	The AI agent for your whole organization. It reads and acts on your apps and knowledge but doesn't change their code. See Starcat.
Starcat Developer	The AI agent in an app's Build tab that writes the app's code from a conversation in the browser, for when you can't run a coding agent locally. See Starcat Developer.
Starlens	Stardeck's document reader. It turns photos, PDFs, audio and video into the fields your app needs. See Starlens.
Surface	An experience inside an app for one audience or device, with its own name, URL and icon, such as a counter register or a booking page. See Surfaces.
Ultra mode	A Starcat Developer mode for large changes: several writers work in parallel and the agent tests its own work, within a spending budget. See Ultra Mode.
Update	A new version of Stardeck's Modules, merged into your app when you take it. See Updates.
Visibility	Who can open an app: anyone, your team, or invited people only. See App Visibility.
