If you’re a Mac user still relying on PuTTY for SSH, it might be time to rethink your toolkit. While PuTTY remains a reliable option on Windows, it was never really designed with macOS users in mind.
In fact, macOS ships with a native SSH client built into the Terminal app. But what if you want more—like automation, scripting, or real-time debugging?
In 2025, there’s a host of modern SSH clients and remote execution environments purpose-built for Mac users, offering intuitive interfaces, enhanced security, and robust features beyond traditional shell access.
Here are the top PuTTY alternatives for Mac, starting with one of the most exciting tools out there: Attune.
Attune
Among the modern SSH clients built with Mac users in mind, Attune stands out as a robust and intuitive solution that goes far beyond simple shell access.
It combines the power of a remote execution environment with automation capabilities, delivering secure, agentless connectivity and real-time debugging tools, all in a user-friendly interface.
Why Attune Stands Out:
Attune goes beyond basic SSH by providing a streamlined execution environment where you can run scripts and applications across multiple servers. Whether you’re deploying updates, scaling environments, or performing automated backups, Attune handles the heavy lifting.
Key Features:
- Agentless automation – No need to install software on remote machines.
- Cross-language scripting – Supports Python, PowerShell, and Bash.
- Secure SSH connections – Built-in security protocols keep your sessions safe.
- Real-time debugging tools – Instantly identify and fix errors as they happen.
- Scalability – Automate repetitive tasks and scale operations with ease.
Attune simplifies your workflow, replacing the clunky experience of PuTTY with a clean interface designed for productivity. It’s ideal for DevOps engineers, sysadmins, and developers looking to reduce manual work without sacrificing control.
Termius
Termius is another modern SSH client that’s made waves among developers, especially those juggling multiple devices. Available for macOS, Windows, Linux, and mobile, Termius syncs your data across platforms so you can pick up right where you left off.
What makes Termius appealing:
- Clean, modern UI – Much more intuitive than old-school terminal windows.
- Snippet support – Save commonly used commands for one-click access.
- Group management – Organise hosts into groups for efficient access.
- SFTP integration – Manage files alongside your SSH sessions.
Though Termius doesn’t offer deep automation or execution environments like Attune, it’s a solid option for users looking for a visually appealing, multi-platform SSH solution.
Warp Terminal
Warp is a reimagined terminal built from the ground up with Rust, offering features aimed at developers who want faster performance and better productivity tools. It’s not just an SSH client—Warp enhances your entire terminal experience.
Why developers love Warp:
- Blazing fast with GPU rendering
- Command palette and input editor – Great for fixing commands before executing.
- SSH-friendly – Works seamlessly with remote connections.
- Modern interface with collaborative tools
While Warp doesn’t offer remote execution environments or built-in automation like Attune, it provides a high-speed, modern interface that complements other SSH tools very well.
iTerm2
iTerm2 is a popular Terminal replacement for macOS users who want maximum flexibility and customisation. It integrates smoothly with the native SSH client and includes a host of features for power users.
Key features:
- Split panes – View multiple sessions side by side.
- Triggers and automation – Custom actions based on output.
- Profiles and hotkeys – Jump between tasks with ease.
- Search and paste history – Save time with smart tools.
iTerm2 is perfect for developers who prefer to stay close to the command line but want a more enhanced and customisable experience. It’s free and open-source, making it a popular choice.
Core Shell
Core Shell is built specifically for macOS and designed with macOS aesthetics in mind. It integrates with macOS Keychain, making key management easy and secure.
Highlights include:
- Tag-based organisation of remote hosts
- Native macOS look and feel
- Mosh support for intermittent connections
- Secure storage of credentials
It’s a simple, elegant option if you want something lightweight and macOS-native, without complex overhead.
Wrapping Up
PuTTY has had its time, but Mac users now have far better tools for secure remote access, automation, and execution. If you’re still wrestling with clunky SSH sessions, it’s time to upgrade.
Attune is the best pick if you’re after automation, scripting support, and scalable server management.
