Tessera 4.1 adds Artifacts, a home for everything your sessions produce, is made for iPhone Duo, and makes Agent Center fast on long conversations. ARTIFACTS (NEW) • Docs, web pages, an agent's changes and files from every session open as tabs that stay with their host, even after the session ends. • It works like a browser: back and forward, an address bar, tabs and familiar shortcuts (⌘T, ⌘L, ⌘[ and ⌘]). • Open in Artifacts replaces Quick Look in the Files panel, and works on a path or link you select in the terminal or in an agent's conversation. • Press + to open a running tunnel's page. • Tabs never connect on their own: they use a connection a session already has, and show their last copy when offline. IPHONE DUO (NEW) • Tessera fits every way you hold it: closed, open, half-folded like a book, and as a laptop. • Open, Artifacts docks beside your session. • Half-folded, each pane keeps clear of the fold. • As a laptop, your terminal or agent sits above the fold, with the keyboard bar and Artifacts on the desk below. • Folding never interrupts a session: it resizes once, when the hinge settles. A TIDIER LAYOUT • The iPad sidebar now has agents, artifacts and settings. Keys and known hosts moved into Settings, and tunnel pages open in Artifacts. • On iPhone, agents get their own tab while Agent Center is on. • A card shows what moved; see it again in Settings → About. AGENT CENTER (EXPERIMENTAL) • Long conversations open in about a second, even when their transcript runs to hundreds of megabytes. • Search scans conversations on your host instead of downloading them, and a result opens at its match. • A notification opens its conversation at the newest reply. • An agent whose tmux pane or window was closed leaves the list, and a waiting agent keeps its question across reconnects. KEYBOARD AND TERMINAL • Hold ⌘ to see every shortcut, including your own. Turn it off in Settings → Keyboard. • Scrolled back to read? You stay on your line while output arrives, through tmux redraws and font changes. • VoiceOver pages through the terminal's history. • Accessory bar keys show pressed the moment you touch them. • Mosh with tmux redraws split panes correctly after switching windows. Tessera now requires iOS 18 or later.
Tessera is a fast, keyboard-first SSH, Mosh, and tmux terminal for iPhone, iPhone Duo and iPad. It connects directly to servers you own or control — no middleman, no account, no tracking. MOVE BETWEEN YOUR DEVICES • Hand off a live session: start on iPad, pick it up on iPhone, then double-tap to take back control. The session keeps running either way. • Your focused session appears in the App Switcher and Dock on your other devices. • Nearby Setup copies your hosts, keys, and preferences to a new device directly over the local network — you choose exactly what to copy, both devices confirm a matching code, and each grant needs Face ID. • Or don't sync at all: choose whether sessions follow you or stay on each device. STAY CONNECTED • First-class tmux integration: auto-attach on connect, so a dropped connection never loses your work. • Native tmux windows as tabs, with real panes. • Mosh keeps your session alive across Wi-Fi ↔ cellular roaming and sleep/wake — pick up exactly where you left off. • Session restore brings your saved hosts and layout back after relaunch. BUILT FOR TOUCH AND KEYBOARD • First-class hardware-keyboard support: shortcuts, a hold-⌘ cheat sheet of every shortcut, and careful handling of modifier keys for real terminal work. • Made for iPhone Duo: closed, open, half-folded or as a laptop, your session fits the pose without reconnecting. • A configurable swipe pad puts arrows, Esc, Ctrl and your own macros in the thumb zone. • Mouse and trackpad support, including scrolling that works. • Find-in-terminal, themes, and adjustable fonts and appearance. • Optional on-device dictation straight into the terminal. FILES, PORTS, AND JUMP HOSTS • Artifacts: open docs, web pages and files from your sessions as tabs that stay with their host. • A remote file panel that tracks your shell's current directory, over SSH and mosh alike — with native iOS sharing to move files and images in and out. • Local port forwarding; open a tunnel's web page in Artifacts. • Jump hosts for servers you can only reach through a bastion. PRIVATE BY DEFAULT • Tessera has no servers, no analytics, and collects no data. Connections go directly from your iOS devices to your machines. SECURITY YOU EXPECT • Keys are generated and stored in the iOS Keychain; Secure Enclave–backed keys never leave your device and can require Face ID to use. • Host-key verification with a persistent known-hosts store. • App lock with Face ID / passcode on launch, background return, and idle timeout. OPEN SOURCE • Tessera is free software (GPL-3.0). The full source code is available at github.com/bambouville/tessera. Tessera requires servers you provide — it is a client, not a hosting service. Mosh and tmux features require mosh/tmux installed on the server.
