ProtoLoop
ProtoLoop helps teams share live prototypes, collect pinned UI feedback, and move faster from review to iteration.
About ProtoLoop
ProtoLoop is a tool for sharing prototypes built with AI coding tools and collecting feedback on them. A prototype can be published with a single command, producing a live app that reviewers can open and comment on directly.
Reviewers do not need to create accounts to leave comments, which lowers the barrier for clients, teammates or test users giving input. Feedback is attached to the real running app rather than to static screenshots or mockups.
Collected feedback can be exported straight into AI coding assistants such as Claude, Codex or Cursor, so the comments can feed the next round of changes. The product is aimed at builders who create prototypes with AI tools and want a short loop between review and iteration.
