Frame0

Frame0 is a wireframing application that lets users create hand-drawn style wireframes quickly. The page describes a library of UI components across desktop, mobile, smartwatch, and web interfaces, with adjustable states such as switch on/off and progress bar values. It offers over 1,500 sketch-style icons derived from the Lucide icon library, and mirrored frames so a master frame can be reused and updated across multiple places. An experimental AI Agent can create wireframes from chat and turn them into code, using the user's own API key from OpenAI, Anthropic, Google Gemini, or Grok, or via the Frame0 MCP Server with tools such as Claude Desktop and Cursor. Shapes can be linked to other pages for click-through presentations. Premium features listed include pre-designed templates, exporting live prototypes to HTML and PDF, and crafted libraries. The page also describes diagramming support for flowcharts, UML Use Case and Class diagrams, and Entity-Relationship diagrams. Platform support includes Windows, macOS, and Linux, with dark mode, shape locking, freehand sketching, and image export to PNG, SVG, JPEG, and WebP. Testimonials on the page describe the app as offline-first.
