❯ open ~/your-project
A fast, native macOS terminal built around projects. Terminals, files, a code editor, Git and Claude Code, together in one lightweight app.
Every project opens as a tab with split terminals, a file tree, an editor and a full Git workflow. There is no separate IDE to launch.
.gitignore
Stage, diff, commit, pull, push and switch branches without leaving the window. Branch, upstream, ahead and behind counts, stashes and the last commit are always in view.
Full xterm-256color and true color, powered by SwiftTerm. Command highlighting as you type, and suggestions from your history. Press Tab or → to accept one.
Your own setup comes first: oh-my-zsh, starship, powerlevel10k, zsh-syntax-highlighting and zsh-autosuggestions are detected and left alone.
Line numbers, syntax highlighting for about 20 languages, auto-indent, and find and replace.
Markdown renders GitHub-style. CSV and TSV open as a sortable table. PDF, Word, RTF and ODT have viewers, and Quick Look covers images, spreadsheets, slides and media.
See your 5-hour and weekly usage for each account, refreshed every 15 minutes without using any quota. Get a notification at 95% and 100% of a limit, and optionally resume waiting sessions when it resets.
Use several accounts, such as personal and work. Sign-in uses Claude Code's own claude auth login, and T11N Terminal never reads or stores your Claude credentials. Switching is always manual and confirmed. Use multiple accounts only as Anthropic's terms allow, not to get around usage limits.
Connect with a password, a key file, or your ssh-agent and ~/.ssh/config. Saved connections sit in the sidebar and each opens in its own tab.
Browse the server's files in the sidebar. Passwords are stored only in the macOS Keychain.
Choose Light, Dark or System, with a separate theme for each. Minimum text contrast keeps output readable when a program picks colors meant for the other theme.

Requires macOS 13 Ventura or later, on Apple Silicon or Intel.
T11N Terminal is not notarized by Apple yet, so macOS blocks the first launch with a message that it cannot verify the developer. Try to open the app and close the warning, then go to System Settings → Privacy & Security and click Open Anyway.
Or run this once in Terminal:
xattr -dr com.apple.quarantine "/Applications/T11n Terminal.app"
You only need to do this once for each downloaded version.
