Sketch Viewer has good features to handle .sketch files for viewing, versioning or sharing. What I like most is that it has the ability to share links to be sent to my colleagues without downloading any software. I also like their collaboration functions, so that different users can edit the same file version. Review collected by and hosted on G2.com.

What I like least about this software is that the users' permission can become poorly managed and invite unwanted people. The only one who should offer the permissions is the administrator. Review collected by and hosted on G2.com.
