ShellDrop vs vSSH: Free iOS SSH for AI Agents vs the Cross-Platform Veteran

20 May 2026 · Daniel Bilsborough

vSSH from Velocity Apps is a long-running iOS SSH client with a companion macOS app. It has mature key management, tunneling, and the small-feature polish that comes from years of paid one-time-purchase releases. ShellDrop is on a different track: free, iOS-only, narrower, and built around tmux sessions attached to AI coding agents on a headless Mac Mini.

Two different apps for two different jobs. Honest side-by-side.

Where ShellDrop differs

Design language and feel

ShellDrop is built with the design as a feature. The hero is a live cyan mesh that breathes behind the brand, six droplet nodes drifting on the edges with master-shot lines tracing connections between them. Switching from Home to a session triggers a per-element shrink cascade where the layout itself animates. The droplet metaphor carries from the App Store icon through tabs and sessions. Built natively in SwiftUI for iOS 17+.

Free

No up-front cost.

Tuned for tmux + Claude Code workflows

Single-finger swipe through tmux scrollback without entering copy mode. The toolbar carries Esc, Ctrl-C, arrow keys, Shift-Tab, and a tmux detach button at all times. Built around the case of leaving a coding agent running in tmux and checking in from a phone.

Secure Enclave SSH keys

v4.1.0 generates P-256 keys inside the iPhone Secure Enclave. Private key cannot be exported, even by the app. Ed25519 and paste-import of unencrypted OpenSSH keys (Ed25519, ECDSA P-256/P-384/P-521) also supported.

iPad layout, tuned for the 13" iPad Pro M4

Full landscape, hardware-keyboard friendly, font scales cleanly. The toolbar centres on the large canvas.

Where vSSH wins

Port forwarding UI

vSSH has a proper port-forwarding interface, local, remote, dynamic tunnels with a manageable configuration screen. ShellDrop expects you to handle this at the SSH config layer.

macOS companion

vSSH ships a macOS client alongside the iOS app. If you want one client across iPhone, iPad, and Mac, that's worth something. ShellDrop is iOS / iPadOS only.

Mature general-purpose SSH

vSSH has been around long enough that the corner cases, agent forwarding, identity files, jump hosts, terminal type negotiation, are well-handled. ShellDrop's SSH layer is newer.

Who should pick which

Pick vSSH if you want port-forwarding via a UI, a macOS companion alongside iOS, or a polished general-purpose SSH client with years of paid-app maturity.
Pick ShellDrop if you're managing AI coding agents in tmux on a headless Mac Mini or VPS, you want Secure Enclave SSH keys, tmux-first scroll, a One Tap command button, and you don't want to pay anything.

FAQ

Is vSSH free?

No. vSSH is a paid one-time-purchase iOS app from Velocity Apps. There is also a macOS version.

Does vSSH support port forwarding?

Yes. vSSH historically supports SSH port-forwarding configurations through its UI. ShellDrop relies on manual -L/-R flags via SSH config.

Does ShellDrop support SSH keys?

Yes from v4.1.0. Ed25519, ECDSA P-256/P-384/P-521 paste-import, plus Secure Enclave-backed P-256 keys.

Which is better for tmux?

ShellDrop. Single-finger tmux scrollback, dedicated detach button, always-visible Esc / Ctrl-C / arrow keys. vSSH renders tmux fine but isn't built around it.

Which is better for Claude Code on a Mac Mini?

ShellDrop. The whole app is built around remote tmux sessions attached to coding agents.


ShellDrop is on the App Store. Universal iPhone and iPad, iOS 17+. Free, no subscription.
