Visily is a wireframe software that enables teams, regardless of size and skills, to brainstorm and create app wireframes. Boasting a rich UI library and advanced AI features, Visily helps non-designers such as founders, product managers, business analysts, and software developers to quickly iterate and validate their ideas.
Marvel is a very strong tool in scenarios where designers seek to quickly create simple prototypes on their desktops using a simple, intuitive interface. It offers “just enough” functionality to create somewhat realistic designs to present to stakeholders and other designers. However, there’s a limit to how “realistic” those designs can be, given that Marvel has somewhat limited functionality around animations. Marvel is not a strong option for those who want to create very complex prototypes with many animations, or for those who want to edit prototypes on their tablet or phone. Marvel is a jewel for simplicity but starts to be difficult to use when creating complicated designs. For creating more complicated prototypes, I would recommend a more robust tool, such as Axure.
When building a new product or even a new startup - this tool is priceless, in demonstrating a product's potential without really building it and investing expensive resources before you have users' validation. It's less usable for any backend planning, or when the system behind is too complicated and any user interaction changes the dataset behind the scenes
I really miss being able to duplicate, make a copy of the prototype I'm working on. Sometimes, I want to make a comparison with detail changes and without being able to duplicate it is difficult.
Compared to other similar services, I feel the animations could be more fluid and smoother.
It could have more free sophisticated icons and images.
Ultimately, InVision was just a better fit for our company's needs. It's probably faster to create prototypes using Marvel, but InVision's collaboration features (comments, notes, etc.) are much more robust, which was helpful for our large team spread across multiple continents. InVision also offers more advanced features, and Marvel felt a little too limited for our overall business needs.
