Frame0 vs Quickmock

Frame0 is desktop wireframing software for making low-fidelity, sketch-style wireframes and prototypes. Its component library covers desktop, mobile, smartwatch, and web interfaces, with adjustable component states, and it includes more than 1,500 Lucide-based sketch-style icons. Shapes can link to pages, external URLs, or navigation actions; prototypes can be presented and exported as interactive HTML or PDF files. The app also supports flowcharts, entity-relationship diagrams, and UML use case and class diagrams. Frame0 runs on Linux, macOS, and Windows. Its free plan has no time or size limit and includes all non-premium features, built-in shapes, and icons. Paid plans are listed monthly, with VAT excluded: Solo is 99.00 USD for one device, Duo is 159.00 USD for two devices, and Team is 79.00 USD for three or more devices. A purchased license is perpetual, but major-version upgrades may cost extra. Exported PDFs may omit characters unavailable in the selected font.

Quickmock is a free, open-source tool for making low-fidelity wireframes. Its editor provides pages, device frames, UI components, shapes, text components, and wireframe elements. Commands include creating and opening projects, saving and exporting, undoing and redoing, copying, pasting and deleting, zooming, and changing settings. The homepage says Quickmock is now available only on desktop, although the listed Free plan names web as its platform. The broader platform list also includes Android, iOS, Linux, macOS, Windows, API, extensions, and self-hosted use. The project README describes a VS Code extension that edits .qm files and configures an MCP server for AI tools. It also says organizations can create custom low-fidelity component libraries, with quotes available by email. Quickmock is identified as free and open source under an MIT license. Users can report bugs or request features through GitHub Issues.
