The best SSH client for iPhone in 2026 (free & paid)

The short answer

There's no single "best" SSH client for iPhone — it depends on what you want. If you want an AI assistant in the terminal and the same app on Android, TermAI is the standout. If you live on iOS and want a fast, keyboard-first terminal, Blink Shell is excellent. If you need polished cross-platform sync with a desktop app, Termius fits. For a fully free native app with no account, Easy SSH; for SFTP inside the Files app, Secure ShellFish; for Panic-grade native polish with Secure Enclave and YubiKey auth, Prompt 3. Below is an honest comparison — based on installing each and connecting a real server from an iPhone — so you can pick the one that matches how you actually work.

iOS has no built-in terminal, so you need one of these apps to SSH at all. The good news: several have a genuinely usable free tier, so you can try before you pay.

Naming note: "iOS SSH client", "iPhone SSH client", "SSH app for iPhone" and "iPhone terminal app" are all the same search, and this page covers all of them. Prices below were checked on the US App Store in August 2026 and vary by region and by Apple's currency tiers — always confirm on the listing before you subscribe.

Picks at a glance

• Best overall for most people: TermAI — free tier that actually connects, AI help in the session, built-in Tailscale, and the same app on Android.
• Best pure iOS terminal: Blink Shell — fastest, most keyboard-tuned, mosh.
• Best if you also work on a desktop: Termius.
• Best fully free, no account, no paywall: Easy SSH.
• Best for files rather than shell: Secure ShellFish.
• Best native polish and hardware-key auth: Prompt 3.

iPhone SSH clients at a glance

Two structural things to notice before the details. First, only TermAI and Termius give you the same client on iPhone and Android — everything else here is Apple-only. Second, only two apps let you connect indefinitely without paying and without an evaluation nag: TermAI (free tier) and Easy SSH (free outright).

The best free SSH client for iPhone (and what "free" actually means)

"Free" means four different things in this category, and the difference matters more than the price tag:

One thing iOS lacks that Android has: a well-known, fully open-source SSH client in the app store the way ConnectBot is on Android. App Store rules around downloading and executing code have kept that niche thin. So on iPhone, the practical route to "free" is a real free tier (TermAI, Easy SSH, Termius Starter) rather than an open-source app. Blink Shell is the closest thing — its source is on GitHub under the GPL — but the App Store build is a paid subscription.

If free is your hard requirement, the honest ranking is: Easy SSH if you want zero limits and no account, TermAI if you want a free tier that still includes AI and Tailscale, Termius Starter if you need the same app on a desktop later. More detail in the best free SSH client guide.

TermAI — best if you want AI help and Android too

TermAI is built around an AI assistant in the terminal: describe a task in plain English and it suggests the command, explains an error, or proposes the next step — grounded in your session. It's also the only one here with built-in Tailscale (reach private servers without a separate VPN app) and the same app on iOS and Android. Keys are generated or imported on-device and stored in the iOS Keychain; Face ID gates the app; sessions survive backgrounding and auto-reconnect (three retries, at 2s / 4s / 6s).

Best for: anyone who wants command help, and people who carry both an iPhone and an Android device.
Trade-off: mobile-only — there's no desktop app (see AI SSH clients). New here? Follow the visual getting-started guide.

The difference from a chat-only AI add-on: tapping Run drops the command straight into the live terminal, so the assistant is part of the workflow rather than a separate chatbot.

What "grounded in your session" means in practice

This is the part generic app lists get wrong, so here it is concretely. When you open the assistant from inside a live SSH session, it is handed the actual state of that box: the OS and distribution, which tools are installed (whether there's a docker or systemctl at all), live disk / memory / CPU load sampled at connect time, the last ~30 lines on screen, your last 10 commands in this session, and the output of the last few commands you ran with Run. So it won't hand you brew install on Ubuntu, and it can tell you "/var is 92% full" rather than making you go look. Open the AI tab standalone instead and it has none of that context — you get generic commands and have to pick a session before Run will execute.

Safety is handled the boring, correct way: ordinary commands go to the terminal and run; commands judged high-risk pop a confirmation and then get typed into the input line without pressing Enter, so the last decision is a human one. If you want the reasoning behind that design, we wrote it up in trusting AI shell suggestions.

Beyond the assistant, the parts you'll use daily: a two-row special-key bar (Esc, Enter, Ctrl-C, Home, End, arrows, Paste, Tab, Ctrl, Alt, Backspace), multiple concurrent sessions, a log-stream mode that colour-codes and filters the last 500 lines and can ship the last 100 to the AI for analysis, a snippet library you can pin to the key bar, and built-in SFTP with in-app text editing. Host-key changes raise an explicit warning rather than failing silently — see host key verification.

Blink Shell — best pure iOS terminal

Blink is fast, keyboard-first, and supports mosh for connections that survive network drops and IP changes — a favorite of people who SSH a lot from an iPad with an external keyboard. It's iOS/iPadOS only and subscription-based (about $19.99/yr after a 14-day trial), and it's a terminal-first app rather than a connection-manager-first one, so it rewards comfort with the command line: you configure hosts in an SSH config file, not a form. It pioneered the location-based keep-alive approach that lets a mobile terminal stay connected in the background, and it's the one client here that documents WebAuthn/passkey sk- key support for SSH on iOS.

The current App Store listing is "Blink Shell, Build & Code", which bundles a separate cloud dev-runtime product (Blink Build) sold on its own credit-based plan. You don't need Build to use Blink as an SSH/mosh terminal — but be aware you're looking at two products in one listing when you read the pricing screen.

Best for: power users on iPhone/iPad who want speed and mosh.
Trade-off: iOS only; no AI assistant; subscription; steeper first hour. See Blink vs Termius and Blink Shell alternatives.

Termius — best cross-platform sync

Termius is polished and syncs hosts, keys, and snippets across iPhone, Android, and desktop. If you switch between a phone and a laptop constantly, that sync is the draw. Its free Starter plan is more capable than people expect — SSH, SFTP, Mosh and port forwarding with a local vault, and it permits commercial use — but it's capped to a small number of hosts on a single device, which is exactly the thing you'd want Termius for. Cloud sync, the cloud vault, a full SFTP GUI, and automation sit behind Pro, around $10/month billed annually (noticeably more month-to-month), which is the priciest option here.

Termius has been adding AI (autocomplete and text-to-command); which parts land in the free tier versus Pro has shifted more than once, so check their pricing page rather than trusting any list — including this one — on that specific point.

Best for: teams and people who want one client across phone and desktop.
Trade-off: the features that justify it are paid; free tier is device- and host-limited. See Termius alternatives or the head-to-head TermAI vs Termius.

Easy SSH, Prompt 3, and Secure ShellFish

Easy SSH (from Argsment) is a newer native client for iPhone, iPad, and Mac with an unusual pitch in a subscription-heavy category: it's fully free — host management, on-device key generation, a multi-session terminal, and fingerprint verification, with no paywall and no account. It needs iOS 17 / macOS 14 or later. If your priority is "free and native, nothing to sign up for," it's the one to try. It has no AI assistant, no built-in VPN and no sync, which is where TermAI differs.

Prompt 3 (by Panic) is a clean, native, privacy-minded client with strong keyboard support and GPU-accelerated rendering, running on iPhone, iPad, Mac and Vision Pro from one subscription. It supports Mosh and Eternal Terminal for sessions that survive network drops, plus jump hosts, port forwarding, and — unusually for mobile — YubiKey and Secure Enclave authentication, and it keeps hosts in sync across devices with Panic Sync. It's about $19.99/yr (7-day trial) rather than the one-time purchase older guides remember, though Panic also offers a lifetime purchase around $99 for people who refuse subscriptions. No AI, no Android version.

Secure ShellFish earns its place with two things: it surfaces your servers inside the iOS Files app over SFTP (genuinely handy for editing files with other apps), and it ships post-quantum key exchange and tmux-aware sessions — rare on mobile. It's free to evaluate, with a paid unlock available either monthly or as a one-time lifetime purchase that covers iPhone, iPad and Mac. It's more a file-manager-first tool than an all-in-one terminal; if files are your actual job, see the best SFTP app for iOS.

Others you'll bump into on the App Store

Search the store and you'll also see NeoServer, TermBean, iTerminal and a rotating cast of new entrants; the category has churned a lot since 2025. They're real apps, but we haven't run any of them against production servers long enough to rank them here, and we won't pretend otherwise. If you try one, apply the same three checks: does it store keys on-device, does it verify host keys on first connect, and does it survive being backgrounded.

How to SSH from an iPhone (the two-minute version)

A lot of people searching "iPhone SSH" or "SSH from iPhone" don't want a comparison — they want the steps. Here they are; the flow is nearly identical in every app on this page.

1. Install a client from the App Store (TermAI, Blink, Termius, Easy SSH — any of them).
2. Add a host: the server's IP or hostname, port (22 unless you changed it), and username (root, ubuntu, pi, ec2-user — whatever your server uses).
3. Choose authentication. Password is fastest to test with; a key is what you should actually use. You can paste an existing private key or generate one on the phone and add the public half to ~/.ssh/authorized_keys on the server. Step-by-step: create an SSH key on iPhone and keys vs passwords.
4. Connect, and accept the host key the first time. That fingerprint prompt is the security model working — if it ever reappears unexpectedly, stop and check.
5. Use the special-key row for Ctrl, Esc, Tab and arrows. Without it, half of the shell is unreachable from an iPhone keyboard.

If it fails, the two overwhelmingly common causes are a wrong username and a firewall that never let you reach port 22 — see connection refused and the general SSH troubleshooting guide. The full walkthrough with screenshots is in how to SSH from your iPhone.

"Best terminal app for iPhone" — two different questions

This search splits cleanly in two, and picking the wrong branch wastes an evening:

• You want to reach a server (a VPS, a Raspberry Pi, a work box, an EC2 instance). Then "terminal app" means SSH client, and you want one from the table above. This is what most people mean.
• You want a shell that runs on the phone itself — Unix commands, Python, a scratchpad with no server involved. Then you want a-Shell or iSH, both free.

Either way, iOS ships no terminal of its own, so you're installing something. The good SSH clients are also good terminal emulators — TermAI, Blink and Prompt 3 all handle full-screen TUIs like htop, vim and tmux correctly, which is the real test of a mobile terminal.

iSH, a-Shell, and "PuTTY for iPhone"

Three things that come up in the same searches but aren't remote SSH clients:

• iSH and a-Shell are local Linux-like shells that run on the phone itself (like Termux on Android). iSH emulates x86 to run Alpine Linux; a-Shell gives you a native Unix toolset plus Python and JavaScript. You can run the ssh command inside them, but there's no host list, key manager, or tap-to-connect, and iSH's emulation makes it slow. Use them to run tools locally, not to manage remote servers.
• PuTTY for iPhone doesn't exist — PuTTY is a Windows program. Any "PuTTY" app on the App Store is unrelated. Use a real iOS SSH client from this list instead (more in PuTTY for Android & iPhone). If you have .ppk keys from PuTTY, convert them to OpenSSH format on a desktop before importing.
• SSHing into an iPhone is the other half of "iPhone SSH", and the answer is no: stock iOS runs no SSH server, and there's no App Store app that can add one. That capability only exists on jailbroken devices. If you want to reach files on your phone from a computer, use the Files app, AirDrop, or an SFTP/WebDAV app instead.

iOS-specific things that actually matter

On iPhone, the "best" client is as much about iOS behavior as features. Eight things to check:

• Staying connected in the background. iOS suspends apps within seconds of leaving the foreground — this is the number one complaint about mobile SSH, and no app can fully escape it. Look for mosh (Blink, Prompt 3) or a keep-alive/auto-reconnect approach (TermAI) so you don't return to a dead session. For anything long-running, the durable answer is server-side: run it inside tmux or screen and reattach.
• Face ID / passcode lock. Your saved hosts and keys should sit behind biometric lock, separate from the phone's own unlock.
• Where the key actually lives. Most clients store keys in the iOS Keychain with biometric access control (TermAI, Termius, Easy SSH). Prompt 3 can go further and generate a key inside the Secure Enclave, where it can never be exported — at the cost of being locked to ecdsa-sha2-nistp256 and to that one device. Blink documents FIDO/passkey sk- keys. The trade-offs are laid out in Secure Enclave SSH keys.
• Key import. You should be able to paste or import an existing ed25519/RSA key, not only generate a new one — including a passphrase-protected one and an AWS .pem. Choosing a type? See Ed25519 vs RSA.
• Files app + SFTP. If you move files a lot, Files-app integration (Secure ShellFish) or built-in SFTP (TermAI, Termius) saves round-trips.
• External keyboard. On an iPad or with a Magic Keyboard, first-class Esc/Ctrl/arrow handling is the difference between pleasant and painful — and on the phone's own keyboard, the on-screen special-key row is non-negotiable.
• Reaching servers with no public IP. Home labs and private cloud boxes are the common case. Either run a VPN app alongside the terminal, or use a client with networking built in — TermAI embeds Tailscale, so tailnet devices appear in the host list with nothing else installed (see Tailscale on iOS).
• Copy, paste and scrollback. Selecting text in a terminal on a touchscreen is genuinely hard; check that long-press selection, paste, and scrollback search work before you commit to an app.

Edge cases the other "best SSH client" lists skip

• SSH to your own Mac. Enable Remote Login in System Settings → General → Sharing, then connect to the Mac's .local name on the same Wi-Fi. Full walkthrough: SSH from iPhone to Mac.
• Raspberry Pi and home servers behind CGNAT. Most mobile networks and many home ISPs give you no inbound path at all, so port forwarding simply won't work. A mesh VPN (Tailscale) or a reverse tunnel is the fix, not a different SSH app. See SSH from iPhone to a Raspberry Pi.
• AWS EC2 from a phone. You need to import the .pem keypair and use the right default user (ec2-user, ubuntu, admin depending on the AMI), and the security group must allow your current mobile IP — which changes constantly on cellular. See SSH to EC2 from your phone.
• Networks that block port 22. Some hotel, café and corporate Wi-Fi allow only 80/443. If you administer the server, having sshd also listen on 443 is the standard workaround; if you don't, tether to cellular.
• Flaky cellular. Switching between Wi-Fi and 5G changes your IP and kills a plain SSH session. mosh survives it by design; auto-reconnect papers over it; a stable tailnet address avoids most of it. Background: mosh vs SSH.
• Jump hosts and agent forwarding. If your fleet sits behind a bastion, check for ProxyJump support specifically — Prompt 3, Blink and Termius (Pro) handle it; support is uneven at the free end of the market.
• Two-factor prompts. Servers with an OTP or push challenge work fine from a phone, but keyboard-interactive prompts render badly in some clients — worth testing before you rely on it in an outage.
• Travelling somewhere with heavy network filtering. A client that assumes a clean route home will fail; see SSH clients that still work from restricted networks.
• Your phone is your only device right now. That's the real use case for all of this. It argues for whichever client makes a 3am fix fastest — which usually means saved hosts, keys already on the device, snippets, and something that helps you remember the command.

How to pick

• Want AI help / also use Android → TermAI
• Fast iPhone or iPad terminal, mosh, keyboard → Blink Shell
• Sync with a desktop app → Termius
• No AI, native, name you trust, hardware keys → Prompt 3
• SFTP in the Files app → Secure ShellFish
• Completely free, no account, no limits → Easy SSH
• Free tier that still includes AI and a VPN → TermAI
• A shell running on the phone itself → a-Shell or iSH
• Came looking for PuTTY → there's no iOS PuTTY; use TermAI, Blink or Prompt 3

FAQ

What's the best SSH client for iOS?
"iOS SSH client" and "iPhone SSH client" mean the same thing. For an AI-native client that's also on Android, TermAI; for the most powerful native iOS terminal, Blink Shell; for cross-platform sync with a desktop, Termius; for free with no strings, Easy SSH. All of them run on both iPhone and iPad.

What's the best free SSH client for iPhone?
Easy SSH if you want every feature free with no account. TermAI if you want a free tier that still includes the AI assistant (5 requests/day), unlimited SSH/SFTP connections and built-in Tailscale. Termius Starter works too, but caps you to a few hosts on one device.

Is there a completely free SSH client for iPhone?
Yes — Easy SSH is free outright, and TermAI, Termius and Secure ShellFish all let you connect without paying. Unlike Android's ConnectBot there isn't a well-known fully open-source iOS option on the App Store, so a free tier is the practical route.

Can you SSH from an iPhone at all?
Yes. iOS doesn't have a built-in terminal, but any app here gives you a full SSH client, including keys, SFTP and port forwarding. The flow — add host, choose password or key, connect — is nearly identical to Android; see our step-by-step iPhone guide.

Can I SSH into my iPhone?
No. Stock iOS runs no SSH server and the App Store doesn't allow one, so there's nothing to connect to; that only works on jailbroken devices. To get files off the phone, use the Files app, AirDrop or an SFTP client instead.

Does iPhone have a terminal app?
Not built in — Apple ships no Terminal on iOS the way it does on macOS. You install one: an SSH client (TermAI, Blink, Termius, Prompt 3, Easy SSH) to reach servers, or a-Shell / iSH for a shell that runs locally on the phone.

What's the best terminal app for iPhone?
For connecting to servers — what most people mean — an SSH client: Blink Shell for raw terminal quality, TermAI for AI help and a free tier, Prompt 3 for native polish. For a local shell with no server involved, a-Shell (native Unix tools plus Python) or iSH (emulated Alpine Linux). Both local options are free.

Can I use PuTTY on iPhone?
No. PuTTY is Windows-only; there's no official iOS version. Use a native iOS SSH client such as TermAI, Blink, or Prompt 3. If you're bringing PuTTY .ppk keys with you, convert them to OpenSSH format first.

Which iPhone SSH client has AI?
TermAI is AI-native and includes the assistant on its free tier, with the session's real context (OS, disk, memory, recent output) behind it. Termius has been adding AI autocomplete and text-to-command, with the exact free/paid split shifting over time. Blink Shell, Prompt 3, Easy SSH and Secure ShellFish have no AI assistant.

Blink Shell or Termius — which should I get?
Blink if the terminal itself is the product for you: speed, mosh, hardware keyboard, config files. Termius if the fleet is the product: many hosts synced across phone, tablet and desktop. Blink is cheaper (~$19.99/yr vs ~$10/mo); Termius is the only one of the two on Android. Full comparison: Blink vs Termius.

How do I keep an iPhone SSH session alive in the background?
You mostly can't — iOS suspends apps quickly. Use mosh (Blink, Prompt 3) or an auto-reconnecting client (TermAI), and for anything that must survive, start it in tmux or screen on the server so you can reattach after the session drops.

Can I use my existing SSH key on an iPhone?
Yes. Every client here can import an existing private key — paste it, or open it from the Files app — including passphrase-protected keys and AWS .pem files. You can also generate a fresh key on the phone and append its public half to ~/.ssh/authorized_keys, which is the better habit: one key per device, revocable on its own.

Is SSH from a phone actually secure?
The protocol is the same one you use from a laptop, so the crypto isn't the weak point — the device is. Use a key rather than a password, keep the key in the Keychain or Secure Enclave behind Face ID, verify the host fingerprint on first connect, and lock the app itself. That setup is arguably harder to attack than an unencrypted key sitting in ~/.ssh on a shared desktop.
