A Progressive Web Application (PWA) for embroidery factories that enables GPS-based attendance, production tracking, worker management, and seamless offline synchronization.

ThreadPilot is a full-stack, offline-first Workforce Management CRM designed specifically for embroidery manufacturing businesses. It streamlines daily factory operations by providing GPS-verified attendance, production tracking, shift management, worker administration, and automated reporting—all within a responsive Progressive Web Application.

The application continues to function even without an internet connection by storing attendance and production data locally using IndexedDB. Once connectivity is restored, all pending records are automatically synchronized with the server, ensuring uninterrupted workflows and reliable data consistency.

Administrators can manage workers, configure factory settings, define day and night shifts, monitor attendance through calendar and list views, generate Excel and PDF reports, and track production performance in real time. Workers can securely log in, mark attendance using GPS geofencing, submit production updates, and manage their profiles from any device.
