CodeX Meet

CodeX Meet is a cross-platform WebRTC-based video calling and interactive meeting application designed to simplify one-to-one conferencing. The application establishes direct peer-to-peer WebRTC connections while using Firebase Firestore as a real-time signaling service, eliminating the need for expensive third-party video conferencing SDKs.

This architecture provides a secure, privacy-focused, low-latency, and cost-effective communication solution.

Built with Flutter, CodeX Meet delivers a responsive user experience across Android, and Web, with layouts optimized for both mobile and desktop environments. The application includes several collaboration features such as real-time chat, live polls, emoji reactions, screen sharing, meeting recording, speech-to-text captions, and transcript exporting.

Users can securely authenticate and join meetings instantly using Room IDs, deep links, or QR code invitations.

Challenges & Solutions

Building a Low-Latency Video Calling Platform Without Third-Party SDKs

Delivering smooth, real-time video communication without relying on expensive conferencing services required a scalable peer-to-peer architecture. We implemented a pure WebRTC solution with Firebase Firestore signaling to achieve secure, low-latency, and cost-effective communication.

Improving Meeting Collaboration and Accessibility

Standard video calls often lack interactive and inclusive collaboration features for remote teams. We integrated live polls, speech-to-text captions, screen sharing, meeting recording, and transcript exports to create a more engaging and accessible meeting experience.

Simplifying Secure Meeting Onboarding

Joining meetings through lengthy manual processes can reduce user adoption and productivity. We enabled secure authentication along with Room IDs, deep links, and QR code invitations to provide fast, seamless, and secure meeting access.
