Best tools for parallel coding agents (2026)

We make Shuriken. We tried to be fair; corrections welcome at office@shuriken.sh.

Quick answer#

There's no single best tool. It depends on your platform and on what runs out first: your patience with terminals, or your plan's limits.

• Mac only, polished, with a team plan: Conductor.
• Mac, "bring any agent", scripting with a CLI and SDK: Superset.
• Free, open source, on every desktop OS: Orca or Emdash.
• You live in the terminal: Claude Squad.
• You only use Codex: OpenAI's own app.
• Your agents keep hitting usage limits, or you work across several machines: Shuriken.

Every tool below gives each agent its own git branch and checkout. The real differences are platforms, agents, price, and what happens when an account runs out.

What to look for#

Isolation#

Two agents in one checkout will overwrite each other's files. The standard fix is a git worktree per task: a separate folder and branch, sharing one repository. All seven tools do this or something like it. Look at how each one gets work back out: a merge button, a pull request, or "you do it". Our guide to running Claude Code agents in parallel covers the mechanics.

Agents supported#

Some tools run one agent, some run dozens. If you pay for Claude and ChatGPT, you probably want both Claude Code and Codex in one place.

Platforms#

Mac-first is common in this category. If you're on Windows or Linux, or want agents on a headless server, that narrows the list fast.

Limits handling#

This one gets skipped in most roundups, and it's the one that bites. Parallel agents burn through a plan's limits several times faster, so you hit the 5-hour or weekly wall before lunch. Does the tool show you usage? Does it let you switch accounts? Does it do it for you?

The tools#

Every claim below comes from the vendor's own page, read on 22 October 2026. Prices are theirs, in US dollars unless noted.

Conductor#

"Run parallel coding agents on your Mac." Conductor runs Claude Code, Codex and Cursor in isolated workspaces, with review and merge built in. Free covers local workspaces with your own subscriptions and keys. Pro ($50 a month) adds cloud workspaces, multiplayer with up to five Pro users, an API and the mobile app. Teams is $60 per user per month.

Good fit if you're on a Mac and want a polished app with cloud workspaces and a team plan.

Superset#

Superset calls itself a workspace for "Claude Code, Codex, and any coding agent". Each agent gets its own git worktree and branch. It has a CLI, a TypeScript SDK and an MCP server, and on Pro adds automations, remote hosts that keep workspaces running while your laptop sleeps, and an iPhone and iPad app. It runs on macOS, with an experimental Linux AppImage; Windows isn't available yet. It's source-available under the Elastic License 2.0. Free is $0, and Pro is $20 per user per month ($15 billed yearly). Superset says it's getting a new name soon.

Good fit if you want to script your agents and you're on a Mac.

Orca#

"Ship 100x with the agent IDE." Orca is free and MIT-licensed, runs on macOS, Windows and Linux, and names 27 agents plus any other CLI. Each task gets its own worktree, and you can fan one prompt out to several agents and merge the best result. It browses GitHub pull requests, issues and Project boards in-app and can create Linear issues. A mobile companion for iOS and Android shows agent status and usage and switches accounts. Orca also shows Claude and Codex usage with their reset times, and lets you hot-swap Codex accounts without logging in again.

Good fit if you want a free, open-source app on any desktop OS, with usage in view.

Emdash#

An "open-source agentic development environment" for macOS, Windows and Linux, with 25+ agents. Tasks run in separate worktrees, each with its own branch, terminal and review state. It pulls issues in from Linear, Jira, GitHub, Notion and Asana, schedules agents, and has a built-in browser. It's free.

Good fit if your work starts from an issue tracker and you want something free and cross-platform.

Claude Squad#

A terminal app that "manages multiple AI terminal agents like Claude Code, Codex, OpenCode, and Amp". Each session runs in its own tmux session and git worktree. It needs tmux and the GitHub CLI, installs with Homebrew or a script, is free, and is licensed AGPL-3.0.

Good fit if you never leave the terminal and want the lightest possible tool.

The Codex app (in the ChatGPT desktop app)#

OpenAI's desktop app now lives inside the ChatGPT desktop app, for macOS, Windows and Linux: you choose Codex when you start a chat. It runs projects in parallel, gives each chat its own git worktree by default (you can pick Local instead), and can schedule recurring tasks. It runs Codex, on your ChatGPT plan.

Good fit if Codex is your only agent and you want OpenAI's own app.

Shuriken#

Ours. A harness for coding agents on macOS, Windows, Linux and headless servers. It runs 67 agents, Claude Code and Codex included. Every chat (except the Main chat) gets its own branch in its own worktree, and Shuriken sets no cap on how many run at once. Finish runs your checks, then merges or opens a pull request. Follow it all from your phone in the web app today; native iOS and Android apps are planned for November 2026. Free is €0 with no card (two sources, two linked devices). Pro is €49 a month or €490 a year (2 months free), VAT included for EU consumers.

Good fit if limits are your bottleneck, or you work across several computers and servers.

At a glance#

Where Shuriken is different#

We'll keep this short, because the list above is the useful part.

It handles the limit for you. Add every Claude, ChatGPT or other account and API key you own as a source. When the account in use reaches your switch point (99% by default, adjustable from 50% to 100%) or hits a limit, your chats move to the account with the most room and keep going. A Claude Code chat moves on its next request, with its subagents. The source switching page explains it. None of the other parallel-agent apps above says it does this automatically; Orca lets you hot-swap Codex accounts by hand, and small CLI switchers exist too (we compared them).

Session limits. Claude's 5-hour window starts when an account is first used. Shuriken sends an idle account one tiny request in the background, once per window, so its window starts early and its limit comes back sooner.

Several machines. Run a chat on another of your computers or servers and the same chat carries on there. Work on one GitHub project from several computers. (Superset's remote hosts and Conductor's cloud workspaces cover part of this too, in their own ways.)

The trade-offs. Shuriken has no hosted cloud sandboxes (your agents run on your own machines, by design), and the native phone apps aren't out yet. Agents only use the accounts you own and are entitled to use; providers' terms may limit how you share a sign-in.

So which one?#

Try two. Every tool here has a free way in. Run the same three tasks in each for a day, and keep the one where you spent the least time babysitting.

If the thing that stops you is a usage limit rather than the UI, download Shuriken and add a second source.
