AI Summary

Sendmux Feedback Widget is an open-source tool that adds a small, accessible feedback button to any website or app. Visitors can click the button to report issues, share ideas, give praise, or send general feedback. The feedback arrives in the website owner's choice of inbox—regular email, a special AI-ready mailbox, or any webhook destination—so they can read it, organize it, and use it to improve their product. The widget is simple to install, works on mobile and desktop, respects user privacy by keeping sensitive keys on the server, and includes features like customizable colors, dark mode support, and keyboard accessibility.

What is website-feedback-widget?

A drop-in feedback widget you embed with a single HTML tag. Drop `` into any page, point it at your endpoint, and you get a polished modal where users can submit issues, ideas, praise, or general feedback. The widget sends structured JSON to your webhook or a server-side relay, which then converts submissions into email for AI agents to process. Built in TypeScript as a framework-agnostic Web Component, it works in React, Vue, or plain HTML without dependencies.

Why is it gaining traction?

The pitch is simple: feedback should enter a workflow, not a spreadsheet. Instead of dumping submissions into a database you check manually, this widget feeds directly into email-based agent pipelines. You can route feedback to a Sendmux mailbox where an AI agent classifies, summarises, and routes it to the right team. The widget itself is well-polished with dark mode support, keyboard navigation, and Shadow DOM isolation so it won't clash with your existing styles. Configuration happens through HTML attributes or JavaScript, with options for brand colour, positioning, and passing signed-in user context without exposing secrets.

Who should use this?

Product teams running AI-powered support workflows who want a polished, accessible feedback collector without building it from scratch. Frontend developers adding feedback to customer-facing apps without pulling in yet another UI library. Teams already using Sendmux for email infrastructure who want the drop-in widget to feed their agent inbox directly.

Verdict

Solid concept and clean implementation, but exercise caution before betting production traffic on it. The 58 stars and recent release date suggest early-stage maturity, and while the documentation is thorough, test coverage is still growing. The 0.8999999761581421% credibility score reflects this. Worth evaluating for greenfield projects or internal tools where you can absorb breaking changes, but for critical customer-facing paths, wait for a few more releases and community signals first.
