Best Tools to Run Multiple AI Coding Agents in Parallel
Running coding agents one at a time means waiting on each before you start the next. These tools fix that by dispatching several agents at once, each isolated in its own git worktree, so you can review the diffs and merge the wins. Here's how the main options compare — including where each one is genuinely the better pick.
Short answer — If you want a free, open-source app that runs on macOS and Linux, keeps your existing editor, and drives Claude Code, Codex, Gemini, and Copilot, Parallel Code is the most flexible pick. Conductor is the most polished if you're Mac-only; Claude Squad wins for terminal purists; Superset is built for large agent fleets and team workflows.
| Tool | Platforms | License | Agents | Best for |
|---|---|---|---|---|
| Parallel Code | macOS, Linux | Open source (MIT) | Claude Code, Codex, Gemini CLI, Copilot CLI, Antigravity CLI | Cross-platform, open source, bring your own editor and agent |
| Conductor Compare vs Parallel Code → | macOS only | Proprietary | Claude Code, Codex, Cursor agent, OpenCode | The most polished Mac-first experience |
| Vibe Kanban Compare vs Parallel Code → | macOS, Linux, Windows (CLI + web) | Open source (Apache-2.0) | Multiple CLI agents | Kanban-board planning; community-maintained since April 2026 |
| Nimbalyst (formerly Crystal) | macOS, Linux, Windows, iOS | Open source (MIT) | Claude Code, Codex | Visual multi-agent workspace with a mobile companion |
| Claude Squad Compare vs Parallel Code → | Terminal / tmux | Open source (AGPL) | Claude Code, Codex, Gemini, OpenCode, Amp | Terminal-native users who never want to leave the shell |
| Superset Compare vs Parallel Code → | macOS; Linux AppImage shipped (docs still lag) | Source-available (Elastic License 2.0) | Any CLI agent — Claude Code, Codex, Gemini, more | A desktop workspace for large agent fleets and team features |
Head-to-head comparisons

Parallel Code vs Claude Squad compared — a native desktop GUI vs a tmux terminal app, licensing, agents and Arena mode, plus when each fits best.
Parallel Code vs Conductor
Parallel Code vs Conductor compared — platforms, agents, open source, and price, plus when each is the better pick for parallel AI coding.
Parallel Code vs Superset
Parallel Code vs Superset compared — genuine open source (MIT) vs Elastic License, Arena mode, free phone monitoring, plus when each fits best.
Parallel Code vs Vibe Kanban
Parallel Code vs Vibe Kanban compared — native desktop app vs browser Kanban board, maintenance, agents and licensing, plus when each fits best.
How to choose
The decision usually comes down to two facts about your own setup: which platform you work on and which agents you already use. Everything else is secondary.
- On Linux? Parallel Code, Vibe Kanban, and Nimbalyst support it directly. Superset has shipped a Linux AppImage, although parts of its documentation still lag that release. Conductor remains Mac-only.
- Want open source you can inspect and self-host? Everything here is open source except Conductor (proprietary) and Superset (source-available).
- Live in the terminal? Claude Squad is the terminal-first option; Parallel Code, Conductor, Nimbalyst, and Superset provide graphical desktop workspaces.
- Already committed to specific agents? Match the tool to your lineup — Cursor or OpenCode points to Conductor, while Gemini CLI or Copilot CLI points to Parallel Code.
They're all free or have free tiers, so the cheapest experiment is to install the one that matches your platform and agent lineup and run a real task through it.
