The README now opens on an animated WebP of the one-minute tour (GitHub won't play an mp4 inline), linking the full-quality mp4. The docs home page autoplays the mp4 in the hero slot. The old hero screenshot and the separate tour poster block are gone.

tty7 is a terminal you can leave running. Close the window, reboot the machine,
|
||
walk to a different laptop — the shells you started are still there, and so are
|
||
the coding agents you left working in them.
|
||
|
||
It is written in Rust, renders on the GPU through Zed's
|
||
[gpui](https://github.com/zed-industries/zed), and parses VT with Alacritty's
|
||
terminal core. In practice that means roughly twice the throughput of Alacritty,
|
||
Ghostty, or Kitty on a big `cat`, and a frame rate that does not fall over when
|
||
something floods the screen.

<Card title="Sessions that outlive the app" icon="power-off" href="/getting-started/concepts">
|
||
A background server owns your shells, not the window. Quit tty7 and your
|
||
builds keep building. No tmux to learn or configure.

<Card title="Editor-grade input" icon="keyboard" href="/terminal/prompt">
|

Ghost suggestions from your history, tab completion that explains each flag,

syntax highlighting, click-to-place-caret, real multi-line editing.

<Card title="Agent-aware" icon="robot" href="/agents/overview">

23 coding CLIs are recognised on sight. Per-pane status dots, notifications

<Card title="Remote work that feels local" icon="server" href="/remote/workspaces">

A native Rust SSH stack with profiles, SFTP, and port forwarding — plus

remote workspaces where files, repos, and panes all stay on the far machine.

<Card title="Git where you are looking" icon="code-branch" href="/git/source-control">

Branch and diff counts on every sidebar row, a source control panel, a diff

<Card title="Scriptable" icon="terminal" href="/cli/overview">
|

A bundled `tty7` CLI that opens panes, sends keys, reads screens, and blocks

until an agent needs you — so scripts and agents can drive the workbench.

The methodology and a one-command reproduction live in
|
||
[`scripts/bench/`](https://github.com/l0ng-ai/tty7/tree/main/scripts/bench).
|
||
|
||
Three decisions account for most of it:
|
||
|
||
- **The PTY is read at device speed** and parsed in large batches, off the
|
||
render path — so drawing never throttles reading.
|
||
- **The hot paths are lock-free.** A big `cat` never waits on the renderer.
|
||
- **The server buffers up to 16 MiB** ahead of the window before backpressure
|
||
applies, which is enough that a flood finishes writing while the window is
|
||
still catching up.
