GitHub - gi-dellav/multistack: Open source lightweight TUI for parallel agent management

2 min read Original article ↗

Run multiple zerostack agents side by side in your terminal, allowing to spawn, watch, rename, kill all underlying processes.

Multistack is designed to be a native, lightweight and open-soruce competitor to Conductor.

What it does

  • Spawn parallel agents: each one gets its own PTY, running zerostack --parallel under the hood
  • Live status tracking: see at a glance who's working [~], done [✓], dead [X], or waiting [ ], with per-agent timers
  • Drop into any agent: hit Enter on a process to see its full terminal output, keystrokes pass straight through
  • Status signal support: multistack listens for start/stop signals from zerostack via Unix sockets, so timers and indicators stay accurate even across headless loop iterations

Install

Homebrew (recommended)

brew tap gi-dellav/tap
brew trust gi-dellav/tap   # required for Homebrew 6.0.0+
brew install multistack    # zerostack installed automatically

Script

curl -fsSL https://raw.githubusercontent.com/gi-dellav/multistack/main/install.sh | bash

Cargo

You need zerostack on your PATH, plus a recent Rust toolchain.

Keybindings

Agent list (normal mode)

Key Action
n Spawn new agent — prompts for a name, creates a git worktree
N Spawn new agent in parallel mode — no prompt, jumps straight to TTY
m Spawn bare agent — no worktree, no --parallel, jumps to TTY
p Add project — opens directory picker
l Remove project and all its agents
h Open lazygit in the project (or agent worktree) directory
s Open $SHELL in the project (or agent worktree) directory
r Rename selected agent
d Delete (kill) selected agent
Enter Drop into the selected agent's TTY
↑ / ↓ Move selection
PageUp / PageDown Jump to previous / next project header
q Quit
Esc Quit (press twice if agents have git conflicts)

TTY view (agent / lazygit / shell)

Key Action
Esc Return to agent list
All other keys Forwarded to the underlying process

Prompt (new agent / rename / new project)

Key Action
Enter Confirm
Esc Cancel
Backspace Delete last character
Printable chars Append to input

Directory picker

Key Action
Enter Add selected directory as a project
Esc Cancel, return to agent list
/ Start filtering directories (type to narrow, Esc to clear)
All other keys Navigate the file tree

Requirements

  • Linux/BSD/macOS (uses Unix domain sockets and PTYs)
  • zerostack v1.5+ built with the status-signals feature (default from v1.5)
  • Rust 1.85+ (2024 edition)
