Frame0
What it is
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 sketch-style icons based on Lucide. Shapes can link to pages, external URLs, or navigation actions, and prototypes can be shown in presentation mode. The app can export interactive prototypes as single HTML or PDF files; PDFs may omit characters that the selected font does not support. Frame0 also supports flowcharts, entity-relationship diagrams, and UML use case and class diagrams. Its experimental AI Agent can use API keys from OpenAI, Anthropic, Google Gemini, or xAI Grok, with usage billed separately by those providers. Frame0 is a file-based desktop app, and its documentation suggests syncing documents with cloud storage services. The free plan has no time limit and includes built-in shapes and all 1,500 icons. Paid plans are listed by month: Solo at $99 a month, Duo at $159 a month, and Team at $79 a month, with VAT excluded.
