Adibb Virtual Classroom & Recording Platform delivers a premium, reliable, and fully localized experience for real-time teaching, learning, and events—across K-12, higher-ed, and professional training. Built on a modern WebRTC core with adaptive bitrate and edge acceleration, it keeps classes stable on low bandwidth while preserving HD quality when networks are strong. Everything—from lesson prep to live delivery to on-demand review—lives in one secure workflow designed for students, teachers, and administrators.

The platform is tightly integrated with Adibb LMS so classes, rosters, grades, and content stay in sync. Teachers create a course in Adibb LMS and launch a live session with one click; attendance, recordings, and assessments flow back automatically. For schools using other systems, we expose clean REST APIs, LTI, and SSO to slot into your existing stack.
