## Why Séance?

Séance is a GTK4 terminal multiplexer for Linux. It auto-detects [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [Codex](https://github.com/openai/codex), and [Pi](https://github.com/badlogic/pi-mono) sessions running inside it and tracks their status (working, waiting for permission, idle) live in the sidebar. Permission requests and task completions are surfaced as desktop notifications with unread tracking. Zero configuration, no dotfile edits: open an agent in a pane and it is tracked.

### Linux-native, not Electron

GTK4 and libadwaita, so it integrates with the rest of GNOME and with tiling WM setups. X11 and Wayland. Blur and transparency on both. GPU-accelerated terminal rendering via [libghostty](https://ghostty.org) (Ghostty used as a library).

### Scrolling layout

Panes are arranged in a horizontal strip that you scroll through, borrowing the layout model from [niri](https://github.com/YaLTeR/niri). Fits long, linear agent sessions better than a tiling grid, and lines up naturally with scrolling tiling WMs.

### Agent-agnostic

Claude Code, Codex, and Pi are auto-tracked out of the box. Adding support for another agent is a hook config PR rather than a rewrite. Agents that do not speak hooks still get all the plain multiplexer features.

### Scriptable

Every action is available through `seance ctl`, which talks to the running instance over a Unix domain socket. Scripts and AI agents can create workspaces, open panes, send input, read terminal output, and query the full session hierarchy. All commands support JSON output.

A bundled [skill file](skills/seance-skill.md) provides AI agents with a complete reference for the `seance ctl` API, so they can use the multiplexer on their own.

### And also

Workspaces, session persistence across restarts, tabs within columns, a command palette, focus-follows-mouse, and no telemetry.

## Installation

### Arch Linux (AUR)

```bash
yay -S seance
```

### Nix (flake)

To run it directly without installing:

```bash
nix run "git+https://github.com/no1msd/seance?submodules=1"
```

To install it persistently into your profile:

```bash
nix profile install "git+https://github.com/no1msd/seance?submodules=1"
```

Both commands compile from source on the first run and cache the result in
the Nix store.

> **Non-NixOS users:** EGL won't initialize without a GL wrapper.
> On Intel/AMD use [`nixGL`](https://github.com/nix-community/nixGL):
>
> ```bash
> nix run --impure github:nix-community/nixGL#nixGLIntel -- \
>   nix run "git+https://github.com/no1msd/seance?submodules=1"
> ```
>
> On Nvidia use [`nix-gl-host`](https://github.com/numtide/nix-gl-host), since
> nixGL's Nvidia wrapper breaks on recent drivers:
>
> ```bash
> nix run github:numtide/nix-gl-host -- \
>   $(nix build --no-link --print-out-paths \
>     "git+https://github.com/no1msd/seance?submodules=1")/bin/seance
> ```

### AppImage

Download the latest `seance-*-x86_64.AppImage` from [GitHub Releases](https://github.com/no1msd/seance/releases), make it executable, and run it:

```bash
chmod +x seance-*-x86_64.AppImage
./seance-*-x86_64.AppImage
```

Requires `libfuse2` on the host. Uses the host's `libGL`/`libEGL`, so Mesa or proprietary GPU drivers must be installed.

To use `seance ctl` from your shell, move the AppImage onto your `PATH`:

```bash
mv seance-*-x86_64.AppImage ~/.local/bin/seance
```

### Building from source

Requires Zig **0.15.2+**, GTK4, libadwaita, OpenGL 4.3+, and Linux (X11 or Wayland).

```bash
git clone --recursive https://github.com/no1msd/seance.git
cd seance
zig build
```

The binary is at `zig-out/bin/seance`.
