Séance-forkTerminal multiplexer for AI coding agents

GPU-accelerated rendering via libghostty. Scrolling layout from niri. Auto-detects and tracks every agent session — zero config needed.

Releases

Real-time agent status

Running, waiting for permission, idle — live in the sidebar. Desktop notifications on permission prompts and completions.

Scrolling pane layout

A horizontal strip you scroll through, borrowed from niri. Long, linear agent sessions fit better than tiling grids.

Scriptable over a socket

Every GUI action has a seance ctl equivalent. JSON output, Unix socket. Agents can drive the multiplexer themselves.

Zero-config hook injection

Open a supported agent and it's tracked. The multiplexer injects hooks into each session without touching your dotfiles.

GPU-accelerated rendering

Built on Ghostty as a library. Fast, correct terminal rendering with ligatures, Unicode, and full GPU acceleration.

And the essentials

Workspaces, session persistence, tabs within columns, command palette, focus-follows-mouse, blur and transparency.

Install

Linux. GTK4, libadwaita, OpenGL 4.3+.

Séance-fork auto-detects every agent above with zero config. Limux ships hooks for Codex, Claude Code, and Gemini CLI; Better Agent Terminal builds Claude Code and Codex in directly. PrettyMux exposes a generic agent-status socket any agent can call, but ships no built-in auto-detection, so it isn't checked for specific agents. The others all use split or tabbed pane layouts rather than a scrolling strip. Better Agent Terminal is a Tauri/webview app (xterm.js), not GPU-rendered, and is driven by a remote WebSocket server instead of a local control socket.

Built on the work of no1msd

Séance-fork is a community fork of Séance by no1msd. The original project laid the groundwork for a Linux-native AI agent multiplexer — we're grateful for that foundation and continue to maintain compatibility with its core features.
