What is PixelPrototypes?
PixelPrototypes is a free design feedback tool that turns static screen images into clickable prototypes. Link screens with hotspots, collect pinned comments from reviewers, and share one link for approval.
Is PixelPrototypes really free?
Yes. PixelPrototypes is 100% free, with no paid plans, no billing and no credit card required.
Can reviewers comment without an account?
Yes, if you allow it. Share links can let anyone with the link view the prototype and leave comments, with an optional password and expiry date.
What file types can I upload?
PNG, JPG, SVG and WEBP screens. Exports from Figma, Sketch, Photoshop or plain screenshots all work.
Is it a good InVision or Marvel alternative?
For clickable prototypes from images, hotspot linking and comment-based design reviews, yes. PixelPrototypes focuses on fast feedback and approval rather than design editing or developer handoff.
What does the AI Summary do?
It reads a screen's comment thread and summarizes it into feedback themes, action items and open questions. It only runs when you click it.
Is my work private?
Projects are private by default. Only you and invited teammates can see them, images are served through short-lived signed links, and share links can be password-protected.
