OpenSSH is the best openssh alternative for most readers because it is free, already built into Windows 10 and 11, macOS, and most Linux systems, and it covers command line SSH, SCP, and SFTP without a separate download. Termius is the best choice when you need the same saved hosts, keys, and snippets on desktop and mobile, with Pro at $10 per user per month when billed annually and a free Starter plan. PuTTY, Bitvise SSH Client, and Tabby cost $0 and suit Windows users and readers who want a free client with no subscription, while SecureCRT at $119 per license and ZOC Terminal at $79.99 one time suit readers who want scripting and terminal emulation in a single licensed client.
OpenSSH is a command line tool, so the best replacement depends on what you miss: a graphical window, saved sessions, file transfer, mobile access, or X11 forwarding. Each price comes from the vendor page listed in Sources and checked on 2026-11-12.

The 8 best openssh alternatives, in detail
OpenSSH
Best for: Command line SSH on Windows, Mac, and Linux
OpenSSH is the reference SSH tool, and it is already on most computers that readers of this guide use. On Windows 10 and 11, macOS, and Linux, the ssh command connects to a server, scp copies files, and sftp moves files in an interactive session. The suite also includes ssh-keygen for key creation, ssh-agent for key handling, and sshd for running a server.
- The trade-off is the interface.
- OpenSSH does not give you a tabbed window, a graphical file view, or a point and click host list.
- You manage hosts in a config file, and you learn the command flags for tunnels, jump hosts, and key options.
- That is fine for developers and system administrators who live in a terminal.
Pros
- Free and open source
- included with Windows 10 and 11, macOS, and most Linux systems
- supports ssh, scp, sftp, key management, and port forwarding
Cons
- No graphical session manager or saved host list in the base client
- setup and key handling stay in the command line
PuTTY
Best for: Simple free SSH and serial on Windows
PuTTY is a free SSH and Telnet client for Windows and Unix, written and maintained mainly by Simon Tatham. The official site lists version 0.85, released on 2026-08-16, and the download page offers MSI installers and a single portable executable. The installer also brings PuTTYgen for key creation and conversion, PSCP and PSFTP for file transfer, Plink for scripted commands, and Pageant for key handling.
- PuTTY suits a Windows reader who wants one small client for occasional server work and serial console access.
- It does not hold tabs in one window, it does not sync hosts across machines, and its session list is plain.
- Download only from the official chiark site or the official Microsoft Store listing, because the PuTTY team states that putty.org is not its site.
- Choose PuTTY for free, light Windows SSH work, and move to Termius or MobaXterm when you need tabs, sync, or a larger host list.
Pros
- Free under the MIT licence
- latest release is 0.85
- includes PuTTYgen, PSCP, PSFTP, Plink, and Pageant
Cons
- No built in tabbed sessions or cloud sync
- key files use the PuTTY format and need conversion for some other tools
Termius
Best for: Same hosts and keys on desktop and mobile
Termius is a modern SSH client for Windows, macOS, Linux, iOS, Android, and iPadOS, and its main strength is carrying the same hosts, keys, and snippets across those systems. Starter is free and includes a local vault, SSH, SFTP, AI autocomplete, port forwarding, Telnet, Mosh, and serial connections. Pro costs $10 per user per month when billed annually, which is $120 per year, and adds a personal cloud vault, sync across desktop and mobile, session logs, and snippet automation.
- Team costs $20 per user per month when billed annually, and Business costs $30 per user per month when billed annually, with shared vaults and access
- The billing detail matters here.
- Termius does not charge for the core SSH client.
- It charges for sync, shared vaults, and team controls, so a reader who works on one machine can stay on Starter and spend $0.
Pros
- Free Starter plan for commercial use
- Pro adds cloud vault sync, session logs, and snippet automation
- runs on Windows, Mac, Linux, iOS, and Android
Cons
- Cloud sync and team vaults need a subscription plan
- monthly billing costs more than the annual rate shown here
MobaXterm
Best for: All in one Windows toolkit with X11
MobaXterm is a Windows application from Mobatek that packs an X11 server, a tabbed SSH client, RDP, VNC, FTP, SFTP, Mosh, and Unix commands such as bash, grep, awk, sed, and rsync into a single portable executable. When you open an SSH session, a graphical SFTP browser appears beside the terminal, so you can edit remote files without a second app. Home Edition is free, but its limits are firm: 12 sessions, 2 SSH tunnels, and 4 macros, and company deployment needs Professional Edition.
- Professional Edition costs $69 per user per year for 1 to 10 users, with 12 months of updates included and renewal optional, and it removes the caps a
- Choose MobaXterm when you work on Windows and want SSH, file transfer, remote desktop, and X11 in one app, and skip it when you need Mac or Linux, bec
Pros
- Home Edition is free
- includes X11 server, tabbed SSH, RDP, VNC, SFTP browser, and Unix commands in one Windows app
Cons
- Windows only, with no Mac or Linux build
- Home Edition caps use at 12 sessions, 2 SSH tunnels, and 4 macros
Bitvise SSH Client
Best for: Free graphical SFTP and terminal on Windows
Bitvise SSH Client is free for all uses, including inside organisations, and it runs on desktop and server versions of Windows. The client combines terminal emulation, graphical and command line SFTP, an FTP to SFTP bridge, and tunneling with dynamic port forwarding through an integrated proxy. It also includes scriptable command line tools and remote administration for Bitvise SSH Server.
- The price structure is unusual and worth stating plainly.
- The client itself costs $0, and an optional licence costs $39.95 per installation or user, with a site licence from $3,000.
- That optional licence adds stronger support and upgrade commitments plus indemnification.
- It does not add core features.
Pros
- Free for all uses, including inside organisations
- graphical and command line SFTP, terminal emulation, and tunneling in one client
Cons
- Windows only, with no Mac or Linux build
- profiles stay on the machine where they were made, with no cloud sync
SecureCRT
Best for: Scripting and tabbed sessions for network teams
SecureCRT is a terminal emulator with SSH support from VanDyke Software, and scripting is its main strength. It runs on Windows, macOS, and Linux, and one licence can register the client on any of those systems, though it can be used on one machine at a time. It supports tabbed sessions, keyword highlighting, SFTP drag and drop, X11 forwarding, and scripting.
- A single licence costs $119 with 1 year of updates, or $190 with 3 years of updates, and volume tiers fall to $100 and $140 at 25 to 49 licences.
- There is a 30 day free evaluation and no free tier, so the first cost is the licence itself.
- Choose SecureCRT when scripting, session management, and a long lived licensed client matter more than a free download, and choose PuTTY or Tabby when
Pros
- Tabbed sessions, scripting, and keyword highlighting
- one licence works on Windows, Mac, and Linux
- 30 day free evaluation
Cons
- No free plan, only a 30 day evaluation
- updates after the first year need an upgrade or maintenance purchase
Tabby
Best for: Free cross platform terminal with SSH tabs
Tabby, formerly Terminus, is a free terminal app for Windows, Mac, and Linux that connects to local shells, serial devices, SSH servers, and Telnet hosts. It has an integrated SSH client with a connection manager, SFTP and Zmodem file transfer, X11 and port forwarding, jump hosts, agent forwarding, login scripts, and a built in password manager with a master passphrase. The terminal also supports PowerShell, PS Core, WSL, Git Bash, Cygwin, Cmder, and CMD, plus split panes, themes, configurable shortcuts, and an encrypted container for SSH secrets.
- Tabby suits a reader who wants a modern tabbed terminal on three desktop systems for $0, with no account and no subscription.
- It remembers tabs and split panes.
- The limit is mobile: there is no iOS or Android build, so a reader who needs SSH from a phone should look at Termius instead.
- Choose Tabby for free cross platform desktop SSH with tabs and themes.
Pros
- Free and open source
- runs on Windows, Mac, and Linux
- SSH connection manager, SFTP and Zmodem transfer, split panes, and themes
Cons
- Desktop only, with no iOS or Android app
- no vendor support plan is listed on the main product page
ZOC Terminal
Best for: Terminal emulation for Windows and Mac
ZOC Terminal is professional terminal emulation software from EmTec for Windows and macOS, and it connects to hosts and mainframes through SSH, Telnet, serial cable, and other methods. Its emulation list includes xterm, VT220, TN3270, TN5250, Wyse, and QNX, which matters for readers who still work with mainframe and legacy systems. The licence is a one time purchase with no monthly fees.
- A licence for ZOC 9 costs $79.99 in the United States, or 79.00 EUR in Europe, and it covers the current version plus all v9 updates, with support inc
- An upgrade from version 8 costs $29.99, and an upgrade from version 7 or older costs $49.99.
- A site licence for 250 to 500 users costs $12,980.00.
- Choose ZOC when you need mainframe emulation and a one time licence, and choose a free client when you only need SSH and SFTP.
Pros
- One time purchase with no monthly fees
- licence covers ZOC 9 and all v9 updates
- supports SSH, Telnet, serial, and mainframe emulations
Cons
- No free plan, only an evaluation period
- no Linux build, with Windows and Mac only
How we chose
We chose tools that replace the core OpenSSH job: secure remote login, file transfer, key handling, and tunneling, with a graphical window or a saved session list where OpenSSH stays in the command line. Prices and plan limits come from official vendor pricing pages and product pages opened on 2026-11-12, and each price is cited in Sources. We did not test any tool hands-on. A unique fact in this guide is that the free tier is often the full client: Bitvise SSH Client is free for all uses, including inside organisations, while Termius charges mainly for sync and shared vaults, and MobaXterm charges mainly to remove the 12 session, 2 tunnel, and 4 macro caps in Home Edition.
