rootshell vs Ergo

rootshell is a desktop-class terminal emulator built on libghostty — the GPU-accelerated engine behind the Ghostty desktop terminal. A local shell on every platform, Mac screen sharing, native SSH, mosh-compatible roaming, tssh, system-wide VPN, native git, and Metal rendering in a single app. NEW: SCREEN SHARING Reach your Mac's screen, not just its shell, from your iPhone or iPad. High Performance mode streams up to 4K at 60 FPS, fully encrypted. Match Client sizing spins up a virtual display sized exactly to your device: no panning, no letterboxing, with remote system audio. Standard VNC mode covers Linux and headless machines, and tunnels over SSH jump hosts. Nothing to install on the Mac — turn on Screen Sharing and connect. Touch, trackpad, hardware keyboard, and two-way clipboard all work, in tabs, splits, or full screen. METAL-ACCELERATED TERMINAL Built on libghostty's Zig core with direct Metal rendering. Smooth scrolling, zero-flicker synchronized output, and full mouse capture for tmux, vim, and zellij. Tabs, split panes, and persistent scrollback across app restarts. THREE REMOTE PROTOCOLS, ONE APP • SSH — Native Swift SSH client with Ed25519, ECDSA, RSA, and post-quantum ML-KEM + ML-DSA. Jump hosts, port and agent forwarding, and Keychain password storage. • Rootshell Roam — Mosh-compatible sessions survive network changes and app restarts. Multipath TCP bonds WiFi and cellular. Predictive local echo keeps typing responsive. STUN-based NAT traversal punches through firewalls. • tssh with QUIC (TLS 1.3) and KCP transport for lower latency, full native scrollback, and session resumption. NATIVE TMUX INTEGRATION Attach in control mode (tmux -CC) and tmux windows become native tabs, panes become real splits — copy, search, and scroll with native gestures. A dashboard shows live window previews, and tabs survive restarts over tssh. SSH VPN Turn any SSH or tssh session into a system-wide VPN. Route all device traffic through your remote server. No extra software on the server — if you can SSH to it, you can VPN through it. NATIVE GIT Clone, commit, diff, log, blame, rebase, cherry-pick, and worktree — in native Swift with SSH transport. Syntax-highlighted pager output and optional AI-generated commit messages. VOICE AI AGENT Talk to an always-on assistant over Gemini Live. It reads scrollback, runs SSH commands hands-free, searches the web, and asks permission before anything risky. OPTIONAL TEXT AI Chat with Claude, ChatGPT, Gemini, or 400+ models via OpenRouter. Bring your own API key. HARDWARE SECURITY KEYS Private keys never leave hardware. FIDO2/WebAuthn authentication with touch-to-sign. SANDBOXED LOCAL SHELL A full local shell with vim 9.1, Helix, SFTP, SCP, curl, jq, mtr, and standard Unix utilities. The rf browser offers yazi-style miller columns with image previews and git indicators. croc peer-to-peer file transfer, flag-aware tab completion, and prompt themes. CLOUD & KUBERNETES Connect to AWS, Azure, DigitalOcean, Akamai (Linode), and Tailscale. Browse instances, access serial consoles, generate EKS kubeconfigs, and debug Kubernetes nodes with ephemeral pods. 450+ THEMES & VISUAL EFFECTS Over 450 color themes with location-based day/night switching. Animated backgrounds — solar, ocean waves, starfields, fireflies — plus Shadertoy-compatible shaders and custom fonts. CUSTOMIZABLE TOOLBAR Drag, reorder, and hide 45+ built-in keys. Create custom keys that send text, key combos, or sequences. Sticky modifiers with tap and double-tap lock. Separate iPhone and iPad layouts. CONNECTION MANAGEMENT Save profiles with folders, tags, and iCloud sync. Quick Connect autocompletes from history and cloud instances. Background SSH tunnels with auto-start. Siri Shortcuts integration. KEYBOARD POWER FEATURES QMK-style mod-tap keys, dictation and CJK input, customizable shortcuts, and Option key as Alt for international layouts.

Ergo for iPhone and iPad is the on-call companion to Ergo for Mac: the cluster you were reading at your desk, in your pocket, read-only on purpose. CONFIGURE ON THE MAC, VIEW ON THE PHONE There is no setup screen. Turn on iCloud sync in Ergo on your Mac and your clusters appear here — names, endpoints and environment tiers travel through your own iCloud account. Credentials never do: they stay in the Keychain of the device that created them, so a synced cluster asks you to sign in once here, through your provider's own page. WHAT IT SHOWS A health ring that counts the pods actually serving, not the pods that exist. A "needs attention" list that names what is unhealthy right now and quotes the cluster's own event underneath it — the words Kubernetes used, not a paraphrase. Your apps, grouped the way the Mac groups them. Pods, workloads and events, worst first, because the reason to open a list on a phone is to find the thing that is wrong. Live logs, streamed from the same endpoint kubectl uses. IT READS. THE MAC WRITES. Restarting, scaling, applying and deleting live on the Mac, behind its confirmation and its audit log. This app cannot make a change to a cluster — not by policy but by construction, and a phone in a pocket at 3 a.m. is the worst place from which to delete a production pod by accident. BUILT FOR BOTH SIZES iPhone gets a single-column app with a floating tab bar. iPad gets a three-pane split — clusters and sections, the list, the drill-in — with keyboard shortcuts, so you can see the pod list and the pod at once. Split View is supported, because a runbook is usually open next to it. HONEST ABOUT WHAT IT DOES NOT KNOW A cluster that will not let you list nodes reads as "—", not as zero nodes. A cluster that does not run cert-manager is not reported as having no certificates. A pod with no CPU limit gets a measurement rather than a percentage of a ceiling that was invented for the gauge. Ergo has no alerting server and will not pretend to page you. TRY IT WITH NO CLUSTER AT ALL A built-in sample cluster is there on first launch — served from data inside the app, no network, no account, nothing to sign in to. Every screen works against it. Ergo is not affiliated with the Kubernetes project or the CNCF. Requires iOS or iPadOS 18. Terms of use https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
