Show HN: Multistack, a TUI environment for parallel coding agents

Multistack, a new open-source TUI environment, lets developers run multiple zerostack coding agents side by side in a terminal, with features for spawning, watching, renaming, and killing processes. The tool, positioned as a lightweight competitor to Conductor, supports live status tracking, per-agent timers, and direct TTY access, and is installable via Homebrew, curl, or Cargo.

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.

  • Spawn parallel agents : each one gets its own PTY, runningzerostack --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 forstart /stop signals from zerostack via Unix sockets, so timers and indicators stay accurate even across headless loop iterations
brew tap gi-dellav/tap
brew trust gi-dellav/tap   # required for Homebrew 6.0.0+
brew install multistack    # zerostack installed automatically
curl -fsSL https://raw.githubusercontent.com/gi-dellav/multistack/main/install.sh | bash
cargo install multistack

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

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
? /F1 Scrollable help overlay (keybindings, statuses, tips)
q Quit — shows confirmation with agent counts ( Enter quits,Esc /n stays)
Esc Quit (confirmation; git conflicts get a warning)
Key Action
Esc Return to agent list
All other keys Forwarded to the underlying process
Key Action
Enter Confirm
Esc Cancel
Backspace Delete last character
Printable chars Append to input
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
  • Linux/BSD/macOS (uses Unix domain sockets and PTYs)
  • zerostack v1.5+ built with thestatus-signals feature (default from v1.5)
  • Rust 1.85+ (2024 edition)
