Speechify is absolutely brilliant. Growing up with dyslexia this would have made a big difference. I’m so glad to have it today.

Sizzy reviews

Sizzy is a powerful selling tool. When we have a prospect who doesn't have a responsive site, when we show them their site on Sizzy, they are impressed and we look even more professional.

- Eric Dingler

I use Sizzy to develop all my apps. Love projects feature, because I always have to switch between 3-4 projects. I enjoy overlay DevTools mode it helps me to easily debug my apps.

Recently migrated a site from global sass to css modules and just having the current production page and the development one next to each other with click & scroll sync is seriously a killer feature within @sizzyapp. Can really recommend it!

ProtoPie reviews

"I love how easy it is to go from a little fragile idea into a full-fledged concept in ProtoPie."

- Eduardo Sonnino, Senior Designer, Microsoft

"ProtoPie enables me to do rapid iterations of our designs."

- Scott Greenwald, UX Designer, Google

"Easy to use and understand" What do you like best about ProtoPie? The walkthroughs and resources for newbies are great. The partnership usage alongside XD is very good. I find the two are a good solution for your prototyping projects. I like the month to month subscription. Pricing is reasonable. Review collected by and hosted on What do you dislike about ProtoPie? Its a little hard to pickup in the beginning, so you do need to spend a bit of time learning the basics. Once you do get it, things will start to click a bit better. I tried to squeeze all I needed to do in the one month trial. That didnt work out so great, so I paid for two months to suit my project. Review collected by and hosted on Recommendations to others considering ProtoPie: Take some timeout to learn the features, use the one month free trial to do that. Review collected by and hosted on What problems is ProtoPie solving and how is that benefiting you? The interactive presentation of a protoype to a client would be the highlight for me. You can show a mockup from the design side of a product, but the additional animations add that extra wow factor.

Pros & cons


Saves time
Many helpful features
One of my must-have tools as a developer.

No online demo
No trial
Sometimes buggy.


It's a completely new tool to learn, I'm sure it's worth the dedication
I love how easy it is to use and all the features it has
It has been sufficient for a learning management system prototype and for other mini projects I've worked on
I am satisfied with the software and I have attracted many users from Iran
Everyone is eager to learn and they ask me questions about protopa."

Things I dislike about Protopie
The desktop view gets cramped with the sidebar interaction and other editor tools
There are only 2 things that bother me, why it does not have an embed system and fonts can be tricky if you sharing the pie with a remote user."“Some limitations such as lack of webcam support on desktop, it can be tedious to recreate some of the basic effects such as button states, formula can be difficult to learn & master for first time users, animation tools is still limited.”
