WebSSH vs Pixel Contrast Checker

Whether you're on the go or at your desk, WebSSH keeps you connected — anytime, anywhere! ٩(^‿^)۶ WebSSH is a professional SSH, Mosh, SFTP, Telnet, Serial and Port Forwarding client for iPhone, iPad and Mac, with a built-in Proxmox client and a complete sysadmin toolbox. Built since 2012 for developers, system administrators and IT professionals who need reliable, secure remote access wherever they are. CONNECT WITH CONFIDENCE Authenticate with passwords, two-factor challenge, or keys (RSA, DSA, ED25519, PuTTY). Jump through bastion hosts, keep an alternative address per host for when you are inside or outside your network, and let known hosts protect you from surprises. Full terminal emulation (XTERM-256COLOR, XTERM, VT100) with WebGL rendering, split panes, inline images, buffer search, session recording and custom profiles — themes, fonts, colors and keyboard shortcuts tailored to your workflow. NEW IN 33: ONE COMMAND, EVERY HOST Run a command or a snippet on several hosts at once and watch the results come back side by side. The Terminal State Bar now shows more about the machine you are on, snippets get keyboard shortcuts on Mac, and the keyboard accessory keys can carry your own icons. MANAGE FILES REMOTELY The integrated SFTP and SCP client lets you browse directories, create, rename, upload and download files — and edit text files directly within the app. WebSSH can also open .txt files from anywhere on your device. MORE THAN SSH Mosh keeps your session alive through network changes, sleep and flaky connections — switch from Wi-Fi to cellular and pick up right where you left off. Telnet supports direct and interactive authentication, including the CP437 character set for BBS servers. Serial connections support full configuration (baud rate, parity, stop bits, flow control). TUNNEL ANYTHING Local and dynamic port forwarding, VPN over SSH to route your device's traffic through a server, port knocking and Wake-on-LAN to reach machines that are not listening yet. PROXMOX AT YOUR FINGERTIPS Connect to one or more Proxmox servers and clusters, monitor your nodes at a glance (CPU, memory, storage), and manage your VMs and LXC containers — start, stop, reboot and migrate them right from your iPhone, iPad or Mac. SNIPPETS THAT WORK FOR YOU Save the commands you type every day, add dynamic variables, sync them from a GitHub Gist and fire them with a shortcut. BUILT-IN SYSADMIN TOOLKIT Quick diagnostics without leaving the app: Ping, Traceroute, DNS Lookup with propagation check, Whois, network scanner, Certificate Checker, Postmaster for SMTP and DMARC audits, HTTP Forge for crafted requests, Hex Viewer, Baker for data transformations, Code Forge for QR codes, Subnet Calculator, Cron generator, Password Generator and end-to-end encrypted Secret Share. The mashREPL local shell (ls, grep, curl, ping, tar and more) works even without internet access. PRIVACY. PERIOD. No account. No analytics. No ads. Your connections stay on your device, and iCloud sync only runs when you turn it on. WHY WEBSSH? Most SSH clients are either too basic or too bloated. WebSSH hits the sweet spot: professional-grade features, a clean mobile-first interface, and rock-solid reliability — every on-device feature unlocked with a single one-time PRO purchase, yours for life on every device. One app. Every protocol. Zero compromises. Download WebSSH and keep your servers close at hand, no matter where you are.
