Browser‑First Event Platform: How a PWA Elevated Event Booking and Attendee Engagement

Project Overview

A rapidly expanding event management company partnered with Cubet to build a cloud-backed Progressive Web App (PWA) that modernized the way they organized corporate events, exhibitions, and public gatherings. The goal was to streamline event bookings, enhance scheduling, and boost attendee engagement without relying on native app downloads.

Event Management / Digital Experience / Progressive Web Applications


The Client

An event management firm organizing corporate and public events across multiple locations. They sought a responsive, mobile-first platform to replace spreadsheets and siloed tools, enabling real-time event logistics and personalized attendee experiences.


Challenges Addressed

The client's reliance on spreadsheets, emails, and disjointed tools led to inefficiencies and poor attendee interaction. Major pain points included:

• Lack of centralised system for event creation, scheduling, and bookings
• Attendee difficulties accessing real-time schedules or registering for sessions
• No offline access or push notifications without building native apps
• Fragmented attendee engagement and limited access to live session updates
• The need for a scalable, cloud-native solution to support large simultaneous events
  
   

Collaboration in Action

Cubet developed a PWA-based event management platform that delivers app-like performance within browsers. The solution enables event organizers to create and manage events, speakers, sessions, and venues—all accessible via a single responsive interface. Attendees can browse, register, build a personalized agenda, and receive real-time updates via push notifications—without ever installing an app.


Technologies Deployed

• Frontend:
  • React framework enhanced with PWA libraries to enable offline support and push notifications
• Backend:
  • Node.js with Express powering APIs for event and attendee data
• Database:
  • MongoDB for storing events, schedules, sessions, and attendee profiles
• Hosting & Delivery:
  • AWS infrastructure coupled with Cloudflare CDN for global performance
• Integrations:
  • Google Calendar sync for attendee agendas
  • Mailgun for transactional email communication
  • OneSignal for reliable cross-device push notifications
    
     

Innovative Feature

The platform’s most compelling innovation is its browser-based PWA architecture, which provides native app-like functionality—offline access, push notifications, QR-based check-in—without the friction of app store downloads. The result is instant accessibility and seamless cross-platform experience.


Value Delivered

• 3× increase in total event registrations within the first six months
• 40% reduction in operational overhead through centralised event management tools
• Improved attendee engagement via personalized schedules, push updates, and session reminders
• Zero dependency on app stores—fully functional browser-based experience
• 99.9% uptime during high-traffic events thanks to scalable backend infrastructure

User Feedback

The Director of Operations shared:

“This PWA completely transformed how we run events. It's fast, reliable, and our attendees love how easy it is to use—no downloads, just click and go.”

Attendees appreciated the seamless experience, quick access to session details and reminders, and the ability to engage without installing an app.


Conclusion

Cubet's PWA-based platform simplified event operations for organizers and enhanced the user experience for attendees. With rapid access, offline support, and intuitive user flows, the solution significantly outperformed legacy systems—offering real-time functionality without the complexity of app development.


Impact Made

By transitioning from manual tools to a browser-first event platform, the client achieved dramatic improvements in registration volume, operational efficiency, and attendee satisfaction. The PWA model proved that high-performing, interactive, and scalable event technology can exist entirely in the browser—no downloads necessary.
