Tool Open source
ZeroTermux is a non-profit Android terminal application developed as a modified version of Termux. It provides backup and recovery, container switching, software-source switching, and support for Linux distributions such as Ubuntu and Kali; it also includes an internally implemented X11 AAR and supports Chinese and English.
The project provides source code and precompiled APK downloads. Its README states that it is released under the GPL license and is intended for learning and communication rather than commercial use. It uses the Tsinghua and Beijing package sources by default for domestic users and recommends that users eventually transition to official Termux.
