Very easy to use, you can import your own pictures as well, prototypes can be made for multiple screen sizes (phones, tabs, web, etc). Review collected by and hosted on G2.com.

The fonts are too small, it would be good if the overall layout was a bit easier on the eyes. Review collected by and hosted on G2.com.

Being capable to prototype and animate, and even adding css and html animations or other snippets. From that perspective is one of the most complete tools out there. Also, unlike most of the famous solutions out there, you can perform the design, the prototype and the interactive presentation all together. Review collected by and hosted on G2.com.

Performance due being a web app, when the boards are too big is not good. Also it lacks some measure and tools to make the design pixel perfect. Quality of rendering sometimes not good either. Review collected by and hosted on G2.com.

I like the libraries of Porto.io and the templates they provide. It help me a lot during design. Review collected by and hosted on G2.com.

When I want to import other project in online editor they don’t have any option for this. Review collected by and hosted on G2.com.

I like how easy is to design and create a prototype at the same type Review collected by and hosted on G2.com.

Not able to export for android mobiles sizes and no clear handover for developers Review collected by and hosted on G2.com.

Proto.io is an easy way to create clickable prototypes. The best thing about the tool is the easiness to animate interactions and the quality of the final outcome. Review collected by and hosted on G2.com.

I wish if the tool had more features to edit create designs. Review collected by and hosted on G2.com.

Obviously, how versatile it is compared to many other choices. Review collected by and hosted on G2.com.

Not always intuitive. I wish it was possible to quickly duplicate interactions. Not really good for showcasing the prototype on mobile devices. Review collected by and hosted on G2.com.

Proto.io has a great UX, it is easier to use that a lot of other prototyping softwares (e.g. protopie). Think of Proto.io as the Wix for prototyping, it has more flexibility than Marvel but functions slights worse (similar to comparing Wix and Squarespace). Review collected by and hosted on G2.com.

It can be very laggy when using the app to build the prototypes. Also it doesn't flow as nice as other softwares mentioned: it is very much a number of screenshots with buttons to link them and some additional features (pop up windows) . Review collected by and hosted on G2.com.

Proto.io is great for creating wire-frames of what you want your mobile/tablet/desktop app to look like. It lets you turn your wireframe into a prototype that looks and feels like an actual application, letting you input data, interact with objects, and go through screens naturally during a demo.

There is a learning curve with some of the advanced features of proto.io, like creating interactive containers. However, no other software that I'm aware of has the interactivity that proto.io has Review collected by and hosted on G2.com.

nothing I liked the best about this tool... customer service care only about your $ Review collected by and hosted on G2.com.

DO NOT USE proto.io !!! еfirst of all - they have so many bugs... my developer and I had to contact customer service many times just to find out there are bugs and we need to change a few things... and it's just not worth it overall. There is a better services out there - just do your search. Also there is no way of exporting your project. I had a slight delay with going forward with my project and needed to pause my subscription - there is a "parking fee" every month. I have been a loyal customer for over a year and paid a lot of money over this period, then I parked it for a few months and still paid monthly "parking" fees... but when I realized I need to put the project on hold - until further notice proto.io customer service was not helpful at all - they said there is no way to back up the project and save it. we live in 21 century - the century of IT - task like this is so simple - they just want you to continue paying them.... If I cancel my subscription - my project will be deleted forever... the only way to keep it is to continue paying ... scumbags! think twice before start using them.

After testing many solutions for creating wireframes and prototypes, I found Proto.io. Because of its many features and integration between design and prototype of layers, using it I had the best user experience so far. It has many functionalities, like animations, layers and other features for high fidelity prototyping, but it's not difficult to understand, learn or use. Review collected by and hosted on G2.com.

Altough its not difficult to use, the interface of Proto.io is a bit cluttered and it lacks space for the design-work on screens that are not so big. The pricing plans for more users are expensive. Review collected by and hosted on G2.com.
