Features and specs

What each product offers, as listed by its team.

PuTTY 5 features
Nuclr.dev 14 features
  • Free and Open Source
    PuTTY is free to use and its source code is openly available. This allows flexibility for users to modify it according to their needs and ensures that there are no licensing costs associated with its usage.
  • Wide Protocol Support
    PuTTY supports various network protocols including SSH, Telnet, SCP, and SFTP. This makes it versatile for different types of server management and data transfer tasks.
  • Lightweight
    PuTTY is a lightweight application that consumes minimal system resources, making it suitable for use on older or less powerful systems without significant performance degradation.
  • Extensible Configuration Options
    PuTTY offers a wide range of configuration options for terminal emulation, keyboard mappings, and connection settings, giving users fine control over their connections and workflow.
  • Portability
    PuTTY can be run as a portable application from USB drives or other external storage devices without the need for a formal installation process on the host system.

Possible disadvantages

  • No Integrated File Manager
    Unlike some other SSH clients, PuTTY does not come with an integrated file manager, which can make tasks involving file transfers less convenient without the use of PuTTY's separate utilities like PSCP or WinSCP.
  • Limited Scripting Capabilities
    PuTTY itself lacks advanced scripting capabilities which can be a limitation for users who need to automate sessions or workflows extensively. External tools or extensions are necessary for these needs.
  • Basic User Interface
    The user interface of PuTTY is quite basic compared to modern applications. It lacks some of the polished features and aesthetics that other terminal clients might offer.
  • No Tabbed Sessions
    PuTTY does not natively support multiple tabbed sessions within a single window, which can make managing multiple connections less convenient. Users typically need to open multiple instances of the application.
  • Windows-Centric
    While PuTTY is primarily developed for Windows, its cross-platform capabilities through ports like PuTTY for Mac or Linux are not as well-supported, leading to potential inconsistencies and lack of features compared to the Windows version.
  • AI coding assistant
    Claude Code, Codex, Pi and OpenCode side by side in one window
  • LLM integration
    Your Claude or ChatGPT plan, or a local model through LM Studio
  • Change Review
    Each turn's changes in a diff viewer, with editor and git history
  • Agent Teams

Questions & Answers

As answered by people managing PuTTY and Nuclr.dev.

What makes your product unique?

Nuclr.dev's answer:

Most AI coding tools give you either a terminal or an editor.

Nuclr Commander gives you the whole workbench: Claude Code, Codex, Pi and OpenCode run side by side in one window, next to a full keyboard-first file manager with panels for your SSH servers, S3, Google Cloud, Docker, Git and SQL databases.

Your keys stay yours. Agents reach those servers and databases through Commander, so the passwords and keys behind them are never shown to the agent, and actions can wait for your approval with the full command shown first.

Agents work as a team. They can message each other, so one writes the code and another reviews it, and you can watch, prompt or stop them from your phone.

Free to download, no account needed, on macOS, Linux and Windows.

Which are the primary technologies used for building your product?

Nuclr.dev's answer:

Nuclr Commander is a native desktop app for macOS, Linux and Windows, with a plugin architecture at its core: file systems, remote servers, cloud storage, viewers and AI agents are all plugins that load into the same panels. Plugins are cryptographically signed and verified before they load. The AI side works with Claude Code, Codex, Pi and OpenCode, and connects agents to your servers and databases through the Model Context Protocol (MCP).

Why should a person choose your product over its competitors?

Nuclr.dev's answer:

If you use AI coding agents: instead of one agent per terminal tab, or one vendor's app, you get Claude Code, Codex, Pi and OpenCode side by side, with your own Claude or ChatGPT plan or a local model. Each turn's changes open in a diff viewer, and agents can hand work to each other - one writes, another reviews.

If you use a dual-pane file manager: you keep the keyboard-first, two-pane way of working from Norton, Total Commander and FAR, on macOS, Linux and Windows alike - plus panels for SSH/SFTP, S3, Google Cloud, Docker, Git and SQL databases, a built-in terminal and quick view for almost any file.

If you do both: this is the only place they live together. Your agents can work with the same servers and databases you browse, through Commander, without ever being shown the passwords and keys behind them - and anything they do can wait for your approval.

Free to download, no account needed.

How would you describe the primary audience of your product?

Nuclr.dev's answer:

Developers who work with AI coding agents every day and want them out of scattered terminal tabs - especially people running more than one agent, or more than one vendor's agent, on the same project.

It suits full-stack and backend developers, DevOps engineers and sysadmins in particular: people whose work spans code, files, SSH servers, cloud storage, containers and databases, and who want their agents to reach all of that without handing over their keys.

It also has a second home with keyboard-first file manager fans - longtime users of Norton Commander, Total Commander, FAR or Midnight Commander - who want that way of working on macOS, Linux and Windows alike.

What's the story behind your product?

Nuclr.dev's answer:

Nuclr Commander is built by one developer. It started in February 2026 as a modern take on the dual-pane file managers I grew up with - Norton Commander, then FAR and Total Commander - because I wanted a file commander I could extend easily, built for how developers work in 2026 rather than in the 1990s. So from the first version, almost everything is a plugin: archives, SSH servers, S3, Docker, Git, databases and viewers all plug into the same panels.

Version 1.0 shipped in July 2026. By then most of my own work happened alongside AI coding agents, and I was juggling them in a pile of terminal tabs while switching to other apps for files, servers and databases. With a commander that was easy to extend, the agents could simply move in: Claude Code, Codex, Pi and OpenCode side by side, working with the same files, servers and clouds, without ever being shown my keys.

It's still the same idea it started with: one keyboard-first window for everything a developer touches - and easy to extend for whatever comes next.

Who are some of the biggest customers of your product?

Nuclr.dev's answer:

Nuclr Commander is used by developers from all walks of life - from backend and full-stack engineers to DevOps, sysadmins and longtime fans of Norton and Total Commander. As more development happens alongside AI coding agents, it's drawing more and more developers who want their agents, files and servers in one window.

It's free to download and doesn't require an account.
