Tabs for every host, SFTP and file previews, built-in Tailscale, and a notification when your coding agent finishes. No Waterm account to create.

The essentials of a remote shell.
The core of Waterm is free with no limits on hosts: SSH, SFTP, key security, session restoration, Tailscale and iCloud Sync.
Every host in a tab
Open connections as tabs, keep your hosts on a Home grid and switch between them like browser tabs. After a relaunch, Waterm reopens your tabs and reconnects each one when you return to it.
Keys under your control
Password, public key, keyboard-interactive and GSSAPI sign-in. Generate Ed25519 keys, or import your existing Ed25519, ECDSA or RSA keys. Host keys are checked on first connection and whenever they change.
Files without leaving the shell
Browse, search, upload and download over SFTP with a transfer queue. Tap a path printed in the terminal to preview it: images, video, PDF, Markdown, JSON and text.
Tailscale built in
Sign in to your tailnet inside Waterm and connect to its machines. No VPN profile to install on your device.
Optional iCloud Sync
Off until you turn it on. Hosts, keys and settings sync through your own private iCloud database. We recommend turning on Advanced Data Protection first.
Waterm Pro
Know when your agent is done.
Waterm works with Herdr, an open-source terminal multiplexer for coding agents. Open Herdr spaces, tabs and panes directly, and get a notification when a Claude Code or Codex agent finishes or needs your attention.
- Each notification shows the host, space and tab it came from.
- Tap it to open that exact pane in a floating terminal.
- Waterm installs the Herdr plugin on your host over SSH, with your permission.
Requires Herdr 0.7.5 or later on a macOS or Linux host. Notifications pass through Waterm's notification relay; the privacy policy explains exactly what it handles.
Also in Pro
- Image and Share Extension uploads. Send photos and shared files straight to your hosts.
- Code and HTML preview. Open code and HTML files from your hosts without leaving Waterm.
- Voice input. Hold to dictate commands and prompts, then review before sending.
- Session Live Activity. Follow a session on the Lock Screen and in the Dynamic Island.
