XDA’s recent piece noted that Windows has been borrowing Linux’s best tricks and Linux has been borrowing Windows’, and the moral is that both operating systems converge on what works. Android sits in the middle: it ships a Linux kernel, and the right apps turn the phone in your pocket into a real Linux box. These eight Linux on Android apps cover terminals, full distros without root, SSH clients, and the rooted heavy-lifters for power users.
What to look for in a Linux on Android app
The category covers several different needs. The criteria that matter:
- Root requirement: Termux, UserLAnd, and Andronix run without root; Linux Deploy needs it.
- Distribution choice: Some apps install a specific distro (Debian noroot), others let you pick from a menu.
- Storage: A full Ubuntu install runs 4 to 8 GB; lighter setups (Alpine, Arch core) under 1 GB.
- Performance: Native userland (Termux) is faster than proot-based emulation. GUI distros via VNC add latency.
- Toolchain: Compilers, package managers, language runtimes, container runtimes (where supported).
- Open-source status: Several apps in this list are GPL-licensed; some prefer F-Droid for the cleanest build.
- Mobile workflow fit: SSH-into-a-server apps are different from “run Linux locally” apps; some users need both.

The 8 best Linux on Android apps
1. Termux — best native Android terminal
Termux is the gold standard. A minimal but functional Linux environment built on Android’s own user space, with its own package manager (pkg), and access to over a thousand packages: Python, Node.js, Rust, Go, Vim, Git, SSH, tmux, even Postgres and Nginx. It runs in your normal user account with no root, no virtualisation, and no proot, so it’s fast.
The 2025 release line restored the Play Store build and added Android 14 and 15 compatibility for the storage-access and notification changes that had broken older Termux installs.
Where it falls short: The Play Store build can lag F-Droid for new package versions. No graphical desktop natively (X11 server packages exist but add complexity). Some commands need workarounds for Android security restrictions.
Pricing:
- Free: Open-source, GPL-3.0.
Platforms: Android.
Termux for Linux on Android: The first app to install when you want a real shell on a phone.
Bottom line: Pick this if you want a real Linux shell on your phone.
2. UserLAnd — best full distros without root
UserLAnd turns Android into a launcher for full Linux userlands without requiring root. Pick from Ubuntu, Debian, Kali, Arch, or Alpine, install the runtime, and you have a full distro running through proot. Add the optional XSDL or built-in VNC server and you get a graphical desktop. The same app handles both terminal-only and GUI sessions through saved profiles.
The 2025 update added Android 14 support and a streamlined first-run experience for users new to the proot model.
Where it falls short: Performance is slower than native Termux because proot adds overhead. GUI sessions via VNC are usable but laggy on lower-end phones. Install sizes are large (4 GB+ for Ubuntu desktop).
Pricing:
- Free: Open-source, GPL-3.0.
Platforms: Android.
UserLAnd for Linux on Android: The friendliest way to install a full distro on a non-rooted phone.
Bottom line: Pick this for a full Ubuntu or Debian environment without rooting your phone.
3. Andronix — best guided distro installs
Andronix is a paid commercial layer on top of Termux that wraps the install process in a one-tap UI. Pick a distro (Ubuntu, Debian, Kali, Manjaro, Arch, Fedora), pick whether you want a desktop environment, and Andronix runs the install scripts for you. The desktop side uses Termux’s X11 packages with a VNC server.
The Andronix Premium subscription adds access to additional desktop-environment options (KDE Plasma, GNOME, MATE, LXQt) and modded distros.
Where it falls short: Premium subscription gates the most-wanted desktop options. Performance ceilings are the same as Termux’s. The wrapper requires Termux to be installed first.
Pricing:
- Free: Basic distros with XFCE.
- Paid: Andronix Premium at a one-time fee or a monthly subscription, with more desktops and modded distros.
Platforms: Android.
Andronix for Linux on Android: The shortest path to a full distro with a desktop, if you don’t want to run shell scripts.
Bottom line: Get this if you want a desktop Linux on Android and don’t want to set it up by hand.
4. Debian noroot — best quick Debian with XFCE
Debian noroot is the simplest entry on this list: install the app and you have Debian with an XFCE desktop, no further configuration. It runs in a sandbox with no root access required, includes a useful set of pre-installed apps (Iceweasel browser, Synaptic for package management, LibreOffice), and uses a touch-mapped pointer for the desktop.
It is the right pick for people who want to try a Linux desktop on a phone for a single session without a setup project.
Where it falls short: Pre-bundled package set is dated; the 2024 update modernised it but still trails a fresh Debian install. Performance is closer to UserLAnd than to Termux. No customisation of desktop environment.
Pricing:
- Free: Open-source, GPL-2.0.
Platforms: Android.
Debian noroot for Linux on Android: The zero-configuration Linux desktop on a phone or tablet.
Bottom line: Pick this for the simplest possible Debian desktop on Android.
5. Linux Deploy — best real chroot on rooted phones
Linux Deploy by Meefik is the rooted heavy-lifter. It installs a full Linux distribution into a chroot or LXC container on a rooted Android device, which means native performance, full kernel access, and the ability to run server workloads. Supported distros include Debian, Ubuntu, Kali, Fedora, openSUSE, Arch, Slackware, and CentOS.
For old Android tablets being repurposed as home-server nodes, this is the right tool.
Where it falls short: Requires root. Modern Android versions (10+) have tightened SELinux policies that complicate setup. The desktop GUI flow needs VNC. Project update cadence has slowed.
Pricing:
- Free: Open-source, GPL-3.0.
Platforms: Android (rooted).
Linux Deploy for Linux on Android: The reference tool for full-fat Linux on a rooted Android device.
Bottom line: Pick this if you have a rooted device and want native-performance Linux on it.
6. Termius — best SSH client into Linux servers
Termius is the commercial SSH client that turned into a small platform. SSH, SFTP, Telnet, Mosh, port forwarding, and a synced host list across desktop and mobile. The team plan adds shared connections, secrets vaulting, and access logs that make Termius credible as an enterprise tool. The phone client is the strongest mobile SSH client by interface quality.
The 2025 Snippet feature added shared command libraries for teams, which compares well to the bash-history-file approach.
Where it falls short: The free tier is limited (host count, snippet count, sync). Subscription is required for most “nice to have” features. The paid tier escalates to enterprise pricing fast.
Pricing:
- Free: A handful of hosts, no sync.
- Paid: Pro and Team plans at monthly tiers; lifetime not currently offered.
Platforms: Android, iOS, web, macOS, Windows, Linux.
Termius for Linux on Android: The most polished SSH client for managing real Linux servers from a phone.
Bottom line: Get this if you SSH into Linux servers from your phone for work.
7. JuiceSSH — best fast, friendly SSH client
JuiceSSH by Sonelli is the longtime Android SSH client favourite. The free tier is genuinely usable: SSH, Mosh, Telnet, port forwarding, and a clean tabbed interface for multiple sessions. The Performance Plugin adds CPU, memory, and disk graphs from a connected server.
The pro upgrade is a single one-time purchase, which makes the long-term cost much lower than Termius for solo users.
Where it falls short: No web or desktop counterpart; configuration is per-device. UI hasn’t seen as much refresh as Termius in recent years.
Pricing:
- Free: Most features.
- Paid: Pro tier as a one-time purchase.
Platforms: Android.
JuiceSSH for Linux on Android: The Android-only SSH client with no subscription.
Bottom line: Pick this if you want a no-subscription SSH client on Android.
8. ConnectBot — best open-source SSH client
ConnectBot is the open-source SSH client for Android. Public-key authentication, port forwarding, and a clean tabbed UI cover the basics. The codebase is GPL-3.0, the build is reproducible on F-Droid, and there are no analytics or telemetry.
For users who care about open-source guarantees end-to-end, ConnectBot is the right choice over Termius and JuiceSSH.
Where it falls short: UI is functional rather than polished. No cross-device sync, no team features. Plugin ecosystem is small.
Pricing:
- Free: Open-source, Apache 2.0.
Platforms: Android.
ConnectBot for Linux on Android: The free open-source SSH client of choice for privacy-conscious users.
Bottom line: Get this if open-source SSH is non-negotiable.

Frequently asked questions
Can I run Ubuntu on my Android phone?
Yes. Without root, install UserLAnd, Andronix, or Termux. With root, Linux Deploy gives the closest to native performance. Phone storage is the constraint: a full Ubuntu Desktop install with apps lands around 4 to 8 GB.
Is Termux better than UserLAnd?
For a Linux shell with real package management, Termux is faster and lighter because it runs natively without proot. For a full distro environment with sudo and standard apt package layouts, UserLAnd is the better fit. Many users install both.
Do these apps need root?
Most don’t. Termux, UserLAnd, Andronix, Debian noroot, Termius, JuiceSSH, and ConnectBot all run on stock unrooted Android. Only Linux Deploy requires root.
Can I run a server on my Android phone with Linux?
Yes. Termux can run Nginx, Postgres, Node.js, Python, Go, and dozens of other services. Linux Deploy can run a real systemd-managed server stack on a rooted phone. Battery and thermals limit serious load, but background services work for development.
Will Linux on Android void my warranty?
Termux, UserLAnd, Andronix, Debian noroot, and the SSH clients are normal apps and don’t affect warranty. Rooting your phone for Linux Deploy may void the warranty on some devices; check your manufacturer’s policy before unlocking the bootloader.
