Sketch.The.Ripper shows the contents of any .sketch file: artboards, symbols, and text.
It's useful for HTML coding. Unlike complicated tools like Zeplin, Avocode, and Lunacy, it rips the files quickly, showing all the context that it finds useful. And it's completely free.

The Icons8 team never stops sharing free useful stuff to make the process of design and development productive. Cool to see another one here, it's easy to use even for non-designers like me. Keep rocking, guys!
