VantaSSH: Secure SSH Client

VANTA//SSH is a high-performance terminal emulator and SFTP client built for system administrators and power users who need absolute reliability. A distinctive dark-industrial interface, a custom terminal engine, and a connection layer engineered to keep your remote workflows alive even under poor network conditions. Everything stays on your device. No accounts, no cloud sync, no analytics. CORE FEATURES • Persistent SSH Sessions: An integrated foreground service keeps your sockets active when you switch apps or turn off the screen. Never lose progress on a long-running remote script again. • Predictive Echo: Mosh-style local echo cuts perceived latency on high-ping or unstable connections, so your typing stays responsive even when the link isn't. • Custom Terminal Engine: Full ANSI/VT100 with xterm extras — 256 and true-color SGR, alternate screen, bracketed paste and UTF-8, drawn by a canvas. Multiple concurrent sessions with a tab strip, and an industrial theme optimized for OLED screens. • Integrated SFTP Browser: Browse, upload, download and manage remote files over your existing sessions. Built on Android's Storage Access Framework, so it only ever touches the files you pick — no broad storage permissions. Background transfers handle large datasets. • Host Vault: Organize hosts with groups, per-host accent colors, favorites and instant search. Password or public-key auth, startup commands, keep-alive, and ProxyJump bastion chaining. • Identity Vault: Generate Ed25519, ECDSA or RSA keys on-device, or seal hardware-backed keys in the Android Keystore. Trust-on-first-use host-key checking, with loud warnings when a fingerprint changes. • Advanced Port Forwarding: Per-host local (-L), remote (-R) and dynamic (-D / SOCKS5) forwards, toggleable individually. Tunnel databases, dashboards and internal services straight to your device. • Snippet Manager: A reusable command library with parameters and optional auto-run, plus a fast command palette. Full hardware keyboard support including Ctrl/Alt chords. • Biometric App Lock: Gate the app behind fingerprint, face or device credential using Android's BiometricPrompt — your biometric data never leaves the operating system's secure hardware. • Encrypted Backup: Export your entire vault to a single passphrase-encrypted file (AES-256-GCM) and move it device-to-device over any transport you choose. Hardware-backed keys stay sealed in the Keystore and are never exported. WHY VANTA//SSH? Built for the always-on professional. VANTA//SSH uses a dedicated foreground service to hold stateful network connections that ordinary apps drop the moment they lose focus. Whether you're running a database migration or a multi-gigabyte SFTP transfer, VANTA keeps the session up and your data intact. ABSOLUTELY LOCALsession up and your data intact. ABSOLUTELY LOCAL No cloud sync. No accounts. No telemetry, analytics or crash-reporting SDKs. Your hosts, keys, forwards and snippets are stored in local Android storage and never leave your device.
