Detailed take

SSSH3.99 € one-time

Pros: Native tmux session manager, Ed25519 keys auto-deployed on first password login, TOFU verification, 8 themes, no subscription, no tracking, no cloud. Fast, focused, mobile-first.

Cons: iOS only (no macOS/Web). No cloud sync between devices — intentional, for privacy.

Best for: Developers who want one-time purchase, tmux-heavy workflows, and full data ownership.

View SSSH

TermiusFree + 9.99$/mo

Pros: Multi-platform (iOS, macOS, Linux, Windows, Web), cloud sync, snippets, port forwarding, SFTP, mosh.

Cons: Aggressive subscription model — nearly all useful features (port forwarding, key management, multiple devices) require Pro. Sends usage analytics. Heavy app.

Best for: Teams managing many servers across platforms with a budget for monthly subscriptions.

Prompt 314.99 € one-time

Pros: Polished UI, one-time purchase, iCloud sync of hosts, no tracking. Clipboard tools, snippet library.

Cons: No tmux integration, more expensive than SSSH for fewer features in the mobile-first space.

Best for: Users in the Apple ecosystem who want a clean, established SSH client without tmux.

Blink Shell19.99$/yr or 49.99$ lifetime

Pros: Mosh support, full Linux-like experience (mosh, ssh, scp, sftp, vim, tmux via CLI), keyboard shortcuts power-user oriented.

Cons: Steep learning curve. Subscription is the default. tmux is CLI-only (no native UI). Overkill for casual SSH use.

Best for: Power users who want a UNIX shell on iOS more than a "nice SSH GUI".

WebSSH6.99 € one-time

Pros: Cheap, simple, minimal.

Cons: No tmux, basic UI, no iPad-optimized layout.

Best for: Occasional SSH connections only. Limited daily-driver appeal.
