Wireframing tools map screen layouts and flows before coding. They unify UI ideas, enable quick prototyping, and suit founders, PMs, analysts, and devs testing UX.
"Across the most-reviewed tools, teams split between all-in-one collaboration hubs, website planning specialists, and niche prototyping workflows. Figma leads broad product design with shared components, live co-editing, and developer handoff; Relume speeds marketing-site wireframes with AI-generated structure and reusable Webflow/Figma components; Balsamiq remains suited to fast, low-fidelity requirement capture and clickable early flows."
