PuTTY for Android & iPhone: the best mobile SSH alternatives (2026)

Is there a PuTTY for Android?

No — there is no official PuTTY for Android or iPhone. PuTTY is a Windows and Linux desktop program, and it has never shipped a real mobile version. So if you searched "PuTTY for Android" you're really looking for a mobile SSH client that does what PuTTY does. This guide lists the best ones in 2026, and flags one thing to watch: several apps on the Play Store use the PuTTY name but are not the real PuTTY.

Short answer: for an AI-native client with Tailscale built in, TermAI is the closest modern fit on both Android and iPhone. For a stable Android one-time purchase, JuiceSSH. For cross-platform sync, Termius.

Why there's no official PuTTY app

PuTTY is a small, focused desktop SSH client maintained for Windows (and built from source on Linux). Its author has never released an Android or iOS port, and there's no official APK. The apps you'll find by searching "PuTTY APK" are third-party — some are harmless wrappers, others are low-quality clones that simply borrow the name. Since an SSH client handles your keys and passwords, don't install a random "PuTTY" APK; use a known, maintained client instead.

PuTTY-style SSH clients for mobile (2026)

1. TermAI — the closest modern equivalent

If you want PuTTY's job — connect to a server, run a shell — but on a phone and with modern conveniences, TermAI is the closest fit. It runs on both Android and iPhone, keeps your keys on-device, and adds an AI assistant in the terminal plus built-in Tailscale, at $2.99/month with a free tier (5 AI calls/day).

Best for: PuTTY users who want a mobile client with AI and Tailscale, on either platform.

Trade-off: no desktop app — for the desktop itself, PuTTY (or another desktop client) still makes sense.

2–4. JuiceSSH, Termius, ConnectBot

JuiceSSH (Android) is the classic one-time-purchase pick. It's stable and the Pro unlock is a one-time purchase, though it's in maintenance mode now and has no AI. Termius is the mature cross-platform option with sync across phone and desktop, at a higher subscription. ConnectBot is the free, open-source Android client — reliable and zero cost, but dated and without SFTP.

On iPhone specifically, Blink Shell is the strongest native terminal if you don't need Android or AI.

Coming from PuTTY: what changes on mobile

Three things feel different when you move from PuTTY on a desktop to any mobile client:

• Host management is built in. Instead of typing a hostname each time, you save hosts in a list — closer to PuTTY's saved sessions, but central to the app.
• Keys live on the device. You import or generate an SSH key in the app; it stays in the secure keystore rather than a .ppk file on disk. Most clients accept standard OpenSSH keys (convert PuTTY's .ppk with PuTTYgen if needed).
• The keyboard is the hard part. A good mobile client adds a row of keys (Esc, Tab, Ctrl, arrows) above the keyboard — that's what makes a phone usable as a terminal.

How to choose

• Want AI + Tailscale, on Android or iPhone → TermAI.
• Android, prefer a one-time purchase → JuiceSSH.
• Use desktop too and want sync → Termius.
• Want free and open source on Android → ConnectBot.
• iPhone power user, no AI needed → Blink Shell.

FAQ

Is there an official PuTTY app for Android?
No. PuTTY has no official Android or iOS app. Apps using the PuTTY name on the Play Store are third-party; prefer a known, maintained client instead.

Are "PuTTY" APKs safe?
Be careful. An SSH client handles your keys and passwords, so an unknown clone is a real risk. Use a reputable client (TermAI, JuiceSSH, Termius, ConnectBot) rather than a random APK.

Can I use my PuTTY keys on a phone?
Yes, after converting. PuTTY uses .ppk files; export them to OpenSSH format with PuTTYgen, then import the key into your mobile client.

What's the best PuTTY alternative for iPhone?
For an AI-native cross-platform client, TermAI. For a native iOS terminal power-user experience, Blink Shell.
