Sendmux Feedback Widget
A framework-agnostic, drop-in feedback widget for a website or app that turns each submission into structured email and webhook data an AI agent workflow can classify, group and route.
Sendmux Feedback Widget is an open-source feedback widget for websites and in-app use, built as a framework-agnostic web component with zero dependencies. It sends each submission as JSON to a chosen destination: a normal inbox, a Sendmux agent mailbox, or the developer's own webhook, so a downstream process can triage it rather than it landing in a spreadsheet.
Once feedback arrives as email or a webhook payload, a connected workflow can classify it as an issue, idea or account-specific request, group duplicates, summarize threads and create or update GitHub issues. The widget itself supports configurable position, brand color and label, logged-in user context, dark mode, reduced motion, and shadow DOM styling to avoid clashing with a host app. It is written in TypeScript and MIT licensed.
