Figma is a popular design prototyping tool which has recently evolved from v1 to v2 with the biggest improvement being the ability to prototype and present the design all from one interface. Figma also comes with a new developer handoff feature. Developers can now have a view-only access to files giving them the ability to see things like color codes, the spacing between elements and CSS details making it quicker to implement the design through code/storyboard.
In Figma, the prototype is a living document rather than a dead artifact.
