InVision shared a vision on collaborative design.
Mockplus accomplished it.

Mockplus helps you hand over all deliverables, like PRDs, wireframes, hi-fi prototypes, design specs, assets, code snippets and much more - every resource from different design processes can be united under one project and delivered to developers using one single link.

In comparison with InVision, Mockplus provides more practical and flexible features to deliver design specs for developers. In addition to auto specs generated once designs are imported from design tools like Sketch, Mockplus offers 5 markup tools to manually mark your design specs more accurately and flexibly.

After handing over specs to developers, they can also easily hover or click on one or more elements to view the spacing, size, height and other measurements. The percentage specs also make it easy for developers to layout interfaces more accurately.

View your entire design project with a bird's eye view. Automatically arrange your artboards as you do in Sketch, Figma, Adobe XD or Photoshop. Combined with the logic lines, you can easily convey the relationships and logic jumps between pages with drag-and-drop. You can also add status tags to pages with different colors and icon shapes on your Storyboard to visually indicate the importance and completion status of the page.

InVision lets you make transitions between artboards. With Mockplus, you can easily make smart and lifelike transitions, interactions, and animations between artboards, pages, even components. Hovering effects, image carousels, loading spinners and other beautiful visual effects can also be done by dragging and dropping.

More importantly, with InVision you are stuck using static components while Mockplus helps you create custom, interactive components for quick reuse.

Unlike InVision that allows only one editor at a time, Mockplus enables your entire team to edit the same project or even the same page in real time. Any changes are automatically updated for all team members instantly. When one member is editing an element on one page, Mockplus will auto lock the element to avoid any editing conflict. Co-editing will never end up with chaos.

To boost your efficiency, Mockplus is designed to be as simple and easy-to-use as possible. It comes with built-in components and icons to help you quickly draw up your project pages. All components come with complete interactive effects and fully editable copies and styles. Whether it is a low-fidelity wireframe or a high-fidelity design, Mockplus can do it all for you as quickly as possible.
