Userback is a visual feedback and bug reporting tool letting users annotate screenshots and record sessions to communicate issues to product teams.
Userback is a visual feedback and bug reporting platform that allows end users to annotate screenshots, record short screen sessions, and submit structured feedback directly from within a web application. When a user encounters a problem or wants to suggest an improvement, they click the Userback widget, draw annotations on a screenshot of exactly what they are seeing, optionally record a brief screen capture with narration, and submit the feedback — all without leaving the product. The submission automatically captures technical metadata including browser version, operating system, screen resolution, console errors, and the current page URL, giving developers the context they need to reproduce and fix issues efficiently.
