What is Zync?

A desktop workspace for local terminals, SSH connections, files, and tunnels. Start on your machine, then connect to your servers.

Why Zync

Your servers.
Your workspace.
Your rules.

Less switching between tools. More control over how you work.

Start without the signup

Free to use. Ready when you are.

Open a local terminal or connect over SSH without creating an account or paying for a desktop subscription.

Unlike ‘100% free’ that becomes ‘please upgrade’ after 30 days.

Alternatives

Your workflow matters too.

Not every SSH client is built around the same idea. Some put the IDE first. Some put managed access first. Zync puts the entire workspace on your machine.

Getting started

04 questions

Is Zync really free?

Yes. Zync is free to use, with no subscription-gated features. Desktop source is available under FSL-1.1-ALv2.

Is Zync a good free SSH client?

Zync is a strong fit if you want a free desktop SSH client with terminals, SFTP, tunnels, snippets, and an encrypted local vault in one app. Its source is available under FSL-1.1-ALv2, and local terminals or SSH connections do not require an account.

I am on Windows. Do I need WSL?

No. Zync runs natively. WSL is optional. PowerShell, Command Prompt, and Git Bash work out of the box.

Which platforms are supported?

Native binaries for Windows 10/11, macOS (Intel and Apple Silicon), and major Linux distributions.

Workflow

05 questions

Is Zync a Termius alternative?

Yes, for developers who want a local-first desktop SSH workspace instead of a managed cross-device SSH service. Zync is desktop only, its source uses FSL-1.1-ALv2, and credentials stay on-device unless you choose optional encrypted backup.

How does Zync compare with MobaXterm?

MobaXterm is a Windows-focused terminal toolbox. Zync runs on Linux, Windows, and macOS, and focuses on a local-first workspace with terminals, SFTP files, SSH tunnels, vault, sync, plugins, and themes.

Can Zync replace ControlOps or operations platforms?

Zync is an SSH client and desktop workspace, not an incident, observability, or control-plane platform. It can sit beside those tools when you need hands-on terminal, file, tunnel, and credential workflows.

Does it support ProxyJump / bastion hosts?

Yes. Configure jump hosts in connection settings. Zync follows the jump chain.

Is there a plugin system?

Yes. Themes, editor providers, and extensions. Browse the marketplace or see zync-plugin-registry on GitHub.

Data & sharing

04 questions

Where are my SSH keys and passwords stored?

Passwords and keys can live in an on-device vault. Hosts, tunnels, and settings stay on your machine. Optional sync encrypts records to your Google Drive before upload. No Zync account is required.

What is the Vault?

An encrypted on-device store for SSH passwords and private keys. Unlock with a passphrase. A recovery key can be saved offline.

Where does sync data go?

Encrypted records go to your Google Drive (drive.appdata). Zync does not keep a copy on its servers. Sync is optional.

What are Public URLs?

Public URLs (Beta) shares a localhost port with an HTTPS link. It is not SSH port forwarding. Sign in with GitHub or Google (a Zync share account, not Drive Sync).
