The best tools to run multiple coding agents in parallel

There are three kinds of tool for running coding agents in parallel: local worktree apps, the agent vendors' own cloud agents, and agent-neutral cloud workspaces. Local apps run agents on your machine, so they stop when it sleeps. Vendor cloud agents keep going with your laptop closed, but most of them run only their vendor's agent. Agent-neutral workspaces run Claude Code, Codex, and others in the cloud, side by side.

Start with git worktree

Two agents in one checkout will edit the same files and undo each other's work. Each one needs its own folder on its own branch, and git worktree gives you that without cloning the repository again:

git worktree add ../app-fix-login -b fix-login
git worktree add ../app-search -b add-search

Start claude or codex in each folder. When an agent finishes, push its branch, open a pull request, and remove its folder, such as git worktree remove ../app-fix-login once the login fix is in.

That's enough for two agents. Past three or four, the hard part is no longer the code but knowing which terminal is waiting on you, and that's the problem every tool below is trying to solve.

Apps that run agents on your machine

These apps make the worktrees for you and show every agent in one window. Conductor runs Claude Code, Codex, Cursor, and OpenCode on a Mac, and it's free for now. It's also joining Meta. If you'd rather stay in the terminal, Claude Squad runs each agent in its own tmux session. Paradev, which used to be called Superset, runs most CLI agents, and its Team plan adds cloud workspaces.

Two of them run on Windows as well as macOS and Linux: Emdash, which can also run agents on another machine over SSH, and Nimbalyst, which was called Crystal. Sculptor, from Imbue, is a research preview that runs Claude Code, the Pi harness, and other terminal agents. Vibe Kanban puts your tasks on a kanban board, and its community maintains it as an open-source project.

If you already work in Cursor, its editor runs its own agent in local worktrees too.

Each vendor's own cloud agent

Anthropic, OpenAI, GitHub, Cursor, and Cognition each run their own agent in the cloud. You start a task in the browser, it runs in the cloud, and you can open a pull request from the result. Nothing on your end has to stay awake. Parallel tasks still draw on your plan's usage limits.

Claude Code on the web comes with Claude's paid plans, and Codex cloud comes with ChatGPT's paid plans. If you already pay for one of those and use only that agent, start there, because it costs you nothing extra. GitHub Copilot's coding agent starts from an issue, a file, or a pull request, and while the feature is in public preview it can also hand the task to Claude or Codex. Cursor's cloud agents need its Premium plan or higher, and Free and Plus don't include them. Devin runs Cognition's own agent and caps how many sessions each plan runs at once.

Clouds that run more than one vendor's agent

Warp runs its own agent, Claude Code, and Codex in its cloud, and you can start them from Slack, Linear, GitHub, or Warp itself. Its free plan includes a limited number of cloud agents, so you can try it before you pay. Paradev's Team plan, from the section above, also runs agents in cloud workspaces. Vespin is in this group too, and we cover it at the end.

We checked these prices on November 13, 2026. They're for the tool alone, and the model is billed on top unless the vendor's plan includes it.

Picking a kind of tool

If you use one agent and already pay for its plan, use that vendor's cloud agent. If you want a few agents at your desk and don't want to pay for the tool, a local app is enough. You need an agent-neutral workspace when you want Claude Code and Codex running in the cloud together, or when a team wants to see everyone's agents in one place.

What Vespin does, and what it doesn't

Vespin runs Claude Code and Codex in cloud sandboxes, on your Mac, or on a Linux machine you add. The center of it is an inbox: an agent posts there only when it needs a decision or a review, so you aren't checking terminals to find out. Agents can also split a task into sub-tasks and start other agents on them. Your team shares a workspace, and our Slack bot can start agents and send you inbox threads as DMs.

It's free and open source under Apache-2.0. Agents run on your own Claude or ChatGPT plan or API key, so we never bill you for model usage. There's a Mac app for Apple silicon and a web app you can open on your phone.

We run only Claude Code and Codex. If you want Gemini, Amp, or Aider, use one of the local apps instead: Paradev runs Gemini, Emdash runs Amp, and Claude Squad runs Aider. And if you only ever run one agent, its vendor's own cloud agent is simpler than adding us.
