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 running 10+ terminal agents at once.
| Tool | Platforms | License | Agents | Best for |
|---|---|---|---|---|
| Parallel Code | macOS, Linux | Open source (MIT) | Claude Code, Codex, Gemini CLI, Copilot CLI | Cross-platform, open source, bring your own editor and agent |
| Conductor Compare vs Parallel Code → | macOS only | Proprietary | Claude Code, Codex, Cursor agent | The most polished Mac-first experience |
| Vibe Kanban | 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 | Terminal / tmux | Open source (AGPL) | Claude Code, Codex, Gemini, OpenCode, Amp | Terminal-native users who never want to leave the shell |
| Superset | macOS | Source-available (Elastic License 2.0) | Any CLI agent — Claude Code, Codex, Gemini, more | Running 10+ terminal agents at once; opens worktrees in your editor |
Head-to-head comparisons
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 run there; Conductor and Superset are Mac-first today.
- 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 and Superset are terminal-first; Parallel Code, Conductor, and Nimbalyst are GUI apps.
- Already committed to specific agents? Match the tool to your lineup — Cursor's agent 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.
