A web SFTP client
A web SFTP client gives you the remote filesystem in a browser tab — no desktop transfer tool, no Windows requirement, and a shell in the same session when a file change needs a service restart.
Files and shell in one place
Most file work on a server is not really file work. You edit a config, restart something, read a log, then fix the config again. Desktop transfer tools separate those steps across two applications, which is why they are traditionally used in pairs with a terminal emulator.
NebulaSSH keeps the SFTP panel and the SSH terminal in the same session, so the edit-and-restart loop never leaves the tab.
- Drag and drop uploads, including whole folders
- Download, rename, delete and chmod without a shell command
- In-place editing of remote files
- Streamed transfers for large files
- The same session gives you a terminal for the restart
Servers you cannot reach directly
Transfer tools assume a reachable SSH port. A home lab, an office box behind NAT or a customer machine inside a network you do not control breaks that assumption, and the usual answers are a VPN or port forwarding.
The connector agent removes the requirement. Installed on the target machine, it dials out to NebulaSSH, so file transfer works over the same outbound path with nothing forwarded and no static IP.
Working from any machine
Because it is a web application, the same file manager works on a locked-down work laptop, a Chromebook, a borrowed desktop or a tablet — with no installer and no admin rights.
Common questions
Does it support SFTP or FTP?
SFTP, which runs over SSH and is what modern OpenSSH servers expect. There is no separate FTP daemon to expose.
Can I upload a whole folder?
Yes. Drag a folder onto the remote path and the structure is recreated as it uploads.
How big can a file be?
Transfers are streamed rather than held in memory, so large files are handled without loading them into the browser.
Can I edit a file without downloading it?
Yes. Files can be opened and edited in place, which is usually what you want for a config change followed by a service restart.
Try it on a machine you are sitting at
Open a browser, sign in, add a server. Nothing to install — and nothing left behind if the machine is not yours.
