Moqups is a browser-based visual collaboration tool covering wireframes, higher-fidelity mockups, diagrams, and flowcharts in one canvas, with built-in stencil kits and icon libraries.
Going from a rough wireframe to a higher-fidelity mockup happens in the same file rather than a handoff to a separate tool, and the diagramming/flowchart support means it can double as a lightweight process-mapping tool too.
Good for cross-functional teams (PMs, business analysts, designers, developers) who want one shared canvas rather than separate tools per discipline; free tiers exist for students and nonprofits.
Real-time collaboration and the higher-fidelity mockup features are the draw, but as a generalist tool it's less deep than a dedicated wireframing app like Balsamiq or a full design tool like Figma at either extreme.
Create and collaborate on wireframes, mockups, diagrams.
