TrueConf

TrueConf provides a self‑hosted platform for corporate communications, combining video conferencing and instant messaging in a single application. It supports UltraHD (up to 4K) video calls with up to 2 000 participants and includes a messenger that allows personal and group chats, file sharing, and integration with corporate directories. The free tier permits up to 1 000 online users, ten professional users, one SIP/H.323/RTSP connection, and a single guest connection, while the on‑premises architecture enables control over data and network traffic.

The system is designed for enterprises that need an on‑premises solution with features such as single sign‑on, multi‑factor authentication, role‑based access, and monitoring tools. It also offers AI‑based capabilities like transcription, content sharing, slideshows, and surveys to enhance collaboration. Compatibility with thin clients and external protocols makes it suitable for a range of hardware endpoints.

TrueConf’s licensing model includes a free tier without subscription requirements, and the software is distributed under a proprietary license. It targets small teams up to large organizations that prefer to host their own communications infrastructure while maintaining a unified messenger and video conferencing experience.
