Framer is a prototyping app similar to Axure RP, Framer, Figma, Sketch, Adobe XD, and Invision Studio.
The latest version is free to use, in a browser (Framer Web) or a dedicated desktop app (Framer Desktop), similar to Figma.
The Free plan allows you to create a maximum of three projects, on which you can invite as many people as you want to view it. You can invite a maximum of two others to edit in your project with you.
You can see the full list of what is and isn’t supported on the Free plan, as well as compare it to the other paid plans, on the pricing page.
