nextssh

Someone administering this install either created an account for you, or you registered yourself at /register. Self-registered accounts wait for an admin to approve them — if the login page tells you your account is pending approval, that’s expected, not an error. Come back once you’ve been approved.

Open the + icon in the sidebar (desktop) or the equivalent action (mobile) to start a new session. Give it a name, the host/port/username, and choose how to authenticate: a password, or your personal SSH key (nextssh generates and holds that key for you — see Your SSH key).

Hit Connect. The very first time you reach a given server, nextssh shows you its host key fingerprint and waits for you to approve it before the shell opens. Approve it once; nextssh remembers it and will refuse to connect — loudly — if that fingerprint ever changes later.

On a desktop-sized window, terminals open as free-floating panes you can drag, resize, and snap to a grid; the sidebar rail on the left holds every other action — new session, current sessions, cascade/tile layout, settings, sign out. On a phone or narrow tablet, you get one full-screen terminal at a time with a tab strip and an on-screen keyboard for keys your touch keyboard doesn’t have.

Open a file browser on the same connection to move around the filesystem, edit text files in place, preview images, and drag files straight out to your desktop. It’s a separate window from your terminal, so you can browse and type commands side by side.

Most browsers offer Install app or Add to Home Screen. Installed, nextssh opens without any browser chrome around it, and shows a plain offline page instead of a broken tab if your network drops while it’s closed.

Everything above just scratches the surface — macros for repetitive keystrokes, a clipboard scrapbook that survives across connections, archive browsing, file history, a Database Explorer for MySQL/Postgres/SQLite, public tunnel links for sharing a running app, and more all live in the Full Manual.
