Run ten agents without holding ten in your head.

T1K is a macOS terminal built to lower the load of running many coding agents at once. It shows which session needs you and takes you there, so you stop checking tabs.

T1K’s main window: the sidebar with three sessions that need you, working spinners and project groups, and a finished Claude Code turn in the terminal

✻ Pondering… (12s · esc to interrupt)

One place to look

Amber means it needs you

Every tab shows its agent’s state. Only a tab waiting on you turns amber; the rest stay quiet.

⌘J goes there

Jump to the tab that has waited longest. Press again for the next.

⌘O shows them all

One screen with every session: what it’s doing, its goal and its last recap.

Switch without starting over

T1K finds the sessions open in your old terminal, whether that’s Warp, iTerm2, Terminal, Ghostty, kitty, WezTerm or tmux, and brings them over with Claude sessions resumed. It can match that terminal’s font and colors too.

Find a tab by what you remember

⌘P searches titles, projects, branches, PRs and files. With the optional helper it ranks by meaning: “the tab where I was fixing login”.

⌘P with “pay” typed: tabs that need you first, then matches by title, project, recap and PR

Restart without losing your place

Tabs and scrollback come back after a quit or an update, and Claude sessions pick up where they stopped.
