The best SSH clients for Mac, Windows and Linux

What to look for in an SSH client

Almost every SSH client can open a session to a Linux box. The differences only show up in the second week: how they organise hundreds of hosts, whether key generation and export are built in, how credentials are stored at rest, and what you end up paying year after year.

• Connection methodspassword, key, certificate and agent auth, plus jump hosts for bastions
• Host managementnested groups, tags, and settings inherited from a parent group
• Key handlinggenerate Ed25519, RSA and ECDSA keys, import existing ones, export public keys
• Credential storagean encrypted local vault you control, versus a vendor cloud account
• Price modela one-time purchase versus a recurring subscription
• Runtime and footprinta native-webview app starts and idles lighter than one that bundles Chromium
• Extra protocolsSFTP, Telnet, Serial and Mosh matter if you touch switches or embedded boards

The best SSH clients at a glance

GUI SSH clients

A GUI client earns its keep once you connect to more than a handful of servers. It remembers hosts, keeps keys in one place, and turns a long ssh command into a click. The trade-off is weight: some clients are fast and focused, others bundle a whole toolbox.

• TerminalXa local-first client that buys once and owns its vault; SSH, SFTP, Telnet, Serial and Mosh in one app
• Termiuspolished and cross-platform with mobile apps and cloud sync; the sync and team features sit behind a subscription
• MobaXterma Windows favourite that packs a terminal, X11 and file browsing into one window
• SecureCRTa long-standing commercial client aimed at teams that need scripting and central configuration

Command-line and built-in terminals

If you already live on the command line, the client is probably already installed. These tools are free, scriptable and identical on every server you reach, which is exactly their strength. They ask more of you: host names, keys and jump chains live in a config file you edit by hand.

• OpenSSHthe ssh, scp and sftp commands; ships with macOS and Linux, and is a built-in Windows feature you can enable
• Windows Terminala modern tabbed terminal for Windows that runs OpenSSH and WSL side by side
• iTerm2a deep, free macOS terminal with splits, profiles and search
• macOS Terminal.appalways there, always enough for a quick session

Most command-line setups store hosts in ~/.ssh/config — a format a good GUI client can import in one step.

TerminalX: the one-time-purchase, local-first pick

TerminalX is a cross-platform SSH client you pay for once. There is no subscription to cancel and no account to create: the app stores everything in an encrypted vault on your machine and runs fully offline after you download it. It is built on Tauri rather than Electron, so it leans on the operating system's native webview instead of shipping its own copy of Chromium. That means a smaller download and lower idle memory than an Electron app of similar scope.

It is a good fit if you want a GUI without a cloud account, or if the per-month price of a managed client has stopped making sense for your own machines.

• SSH over password, key, certificate or agent, with jump hosts and port knocking
• Dual-pane SFTP, Telnet, Serial and Mosh alongside the SSH terminal
• Hosts with nested groups and tags, plus a keychain that generates and imports keys
• Launch pricing: $9 for the first 500 licenses, $19 for the next 250, then $29 — one payment, lifetime updates

How to choose

• You connect to one or two servers a weekthe built-in OpenSSH command is plenty; keep your config tidy and move on
• You manage many hosts and switch between them constantlya GUI client with groups, tags and search pays for itself in saved keystrokes
• You need sync across devices and a phone appa subscription client built around a cloud vault is the natural fit
• You want no account, offline use and a single paymentpick a local-first client such as TerminalX
• You also manage switches or embedded devicescheck that Serial and Telnet are included, not sold separately

Moving your hosts between clients

Switching clients is only painful when you have to retype every host. Good clients import the formats you already have, so you can try one without committing. TerminalX reads ~/.ssh/config, PuTTY, SecureCRT, MobaXterm, CSV and Termius exports. The Termius format is undocumented, so that importer is best-effort against a reverse-engineered layout — always check imported hosts and keys before you rely on them.

Whichever client you land on, keep a plain-text copy of your host list. A config file or a CSV export is the one format every tool can read, and it is what saves you if a vendor shifts direction on pricing.
