CustTermux is a community-maintained fork of the classic Termux terminal emulator. It keeps the lightweight, powerful Linux package environment you love, with specific backports and fixes for legacy systems.
Version 4.8.5 is considered the “golden master” for Android 5. The maintainers have declared no further feature updates, only security backports until mid-2026. However, the universal compatibility layer may be ported to Android 4.4 KitKat in a separate fork (codenamed “CustTermux-Retro”).

In the fast-paced world of Android development, Android 5.0 Lollipop (released in 2014) is often considered ancient history. Yet millions of devices—from rugged industrial handhelds to car infotainment systems and old tablets—still run this version. These devices are far from dead. They simply lack access to modern development tools.
Enter CustTermux-4.8.5-android-5-universal-compatible – a community-driven, backported version of Termux that reopens the door to command-line power on legacy hardware.
