Paper
Paper is a desktop design tool for creating interface layouts on an HTML and CSS canvas and connecting that work with code, agents, and real content.
What is Paper?
Paper is a native desktop design app focused on interface and product design workflows that stay close to production code. It gives designers and product teams a canvas built on HTML and CSS, so layouts, components, and styling can move more directly between design work and development. Paper is used to create screens, refine visual systems, work with real content, and collaborate around design changes that need to ship quickly. The app also supports workflows that connect with code repositories, external tools, and AI agents, which makes it useful for teams exploring design-to-code and code-to-design iteration. On macOS, users will typically install Paper when they want a modern visual workspace for product UI, responsive layouts, and component-based design work. Paper is published by Stephen Haney.

Safety overview
Status: Mostly safe
Paper is legitimate design software for macOS. It may connect to online services, external tools, code sources, and AI agent workflows as part of its normal purpose, so the main practical consideration is what project content you choose to expose through those connections. If you use it with private product designs, customer data, or source code, review the app’s sharing and integration settings and limit access to the material you actually want to use in your workflow.
Recommendation: Keep Paper if you actively use it for interface design or design-to-code workflows. If you no longer use it, removing the app is usually fine, but you may also want to remove its support files later if you want to clear saved settings, cached data, or local project state.
