NinjaMock

Open NinjaMock when you need to turn rough ideas into screens you can click through the same day. Start a project by picking a canvas that matches your target (phone, tablet, or desktop), then drop in ready-made UI parts from the library. Arrange layouts with simple drag-and-place controls, duplicate screens to explore variations, and switch themes to try different visual directions quickly. If you think faster with a pen, sketch freehand with the built-in vector tool to capture flows or custom icons before refining them with components.

Build a working walkthrough without writing code. Add hotspots to buttons or images and point them to any screen to simulate navigation. Set up simple inputs to preview forms and polls, and weave together multi-step journeys like sign-up, checkout, or onboarding. Use the preview to tap through your prototype in a browser or on your phone to validate spacing, copy length, and interaction sequencing. When you’re mapping both mobile and desktop experiences, create parallel canvases to confirm how layouts adapt across form factors.

Bring your team in early and define who can see what. Organize projects inside permissioned folders, invite teammates or clients, and co-edit in real time while leaving comments and mentions on specific elements. Use presentation mode to walk stakeholders through the flow, capture decisions in context, and keep feedback attached to each screen. When a direction is approved, lock it and branch a new version for experiments, so the main flow remains stable for review, testing, or handoff. more
