Multistack v1.0.0 Brings Parallel Agent Management to Your Terminal
The Multi-Agent Terminal You Didn't Know You Needed
If you've been experimenting with AI agent frameworks like zerostack, you've probably hit a common pain point: managing multiple agents running simultaneously. Maybe you're running parallel research tasks, testing different agent configurations, or orchestrating a swarm of specialized workers. Whatever your use case, watching several terminal tabs or juggling background processes gets old fast.
Enter Multistack, a lightweight TUI (Text User Interface) application that brings order to the chaos of parallel agent management.
What Makes Multistack Different
Multistack isn't trying to be a web dashboard or a cloud-based solution. It's deliberately terminal-native, which means:
- Zero overhead: No browser, no Electron, no GUI framework bloat. Just a fast, responsive TUI that sips resources.
- Native feel: If you live in the terminal, this fits your workflow instead of fighting it.
- Privacy-first: Everything stays on your machine. No external services, no telemetry, just pure local processing.
The tool runs multiple zerostack agents in their own PTYs (pseudo-terminals), giving each one true terminal emulation with proper input/output handling.
A Quick Feature Tour
Status at a Glance
The interface uses clear visual indicators to show you what's happening with each agent:
[~]— Agent is actively working[✓]— Task completed successfully[X]— Process died or failed[ ]— Waiting for input
Each agent also gets a per-agent timer, so you can track how long operations take without doing mental math.
Drop Into Any Agent
One of the handiest features: press Enter on any agent and you're dropped directly into its terminal session. Your keystrokes pass straight through to the underlying process. When you're done, hit Esc to return to the agent list. No tmux configuration required.
Signal Integration
Multistack listens for status signals from zerostack via Unix domain sockets. This means the UI stays synchronized with what's actually happening inside each agent—even across headless loop iterations where you might not have direct terminal visibility.
Getting Started
Currently in beta, Multistack requires zerostack v1.5 (also in beta). Here's the quick install:
# Install zerostack v1.5+ if needed
cargo install zerostack --version 1.5.0-rc4
# Install Multistack
cargo install multistack --version 1.0.0-rc2
You'll need Rust 1.85+ (2024 edition) and zerostack on your PATH.

The Bigger Picture
This release signals a growing trend in AI tooling: the move toward local-first, developer-controlled infrastructure. Tools like Multistack appeal to developers who want the power of multi-agent systems without ceding control to hosted platforms.
Whether you're building complex agent pipelines, testing distributed AI workflows, or just want a cleaner way to watch several agents work in parallel, Multistack is worth a look. It's GPL-3.0 licensed, so the code is there for anyone who wants to understand, modify, or contribute.
The terminal isn't going anywhere—and neither are multi-agent workflows. Tools like this one make that future a little more manageable, one PTY at a time.
