What is ABC User Feedback?​

ABC User Feedback is a standalone web application designed to efficiently collect, classify, and manage Voice of Customer (VoC). This open-source solution focuses on systematically managing user feedback to derive insights needed for product and service improvements.

Currently, this application is being used in a service with 10 million Monthly Active Users (MAU), demonstrating proven stability for large-scale feedback processing.

Core Value Proposition​

ABC User Feedback provides the following core values:

  1. Centralized Feedback Management: Manage user feedback collected from various channels in one place
  2. Structured Analysis: Classify feedback and identify trends through the issue system
  3. Issue Tracking: Convert problems found in feedback into issues and track them
  4. Data-Driven Decision Making: Visualize feedback data and derive insights through dashboards

Technology Stack​

ABC User Feedback is built on modern web technologies:

  • Frontend: Next.js - React-based frontend framework
  • Backend: NestJS - Scalable backend framework based on TypeScript
  • Database: MySQL v8 - Reliable relational database
  • Search Engine: OpenSearch v2.16 (Optional) - High-performance search functionality for large amounts of feedback data
