How to run coding agents in parallel on Linux

Give each agent its own git worktree on its own branch and start one agent per worktree in a tmux window. That works on any Linux distribution with git and tmux, and no desktop app is needed. If you want a desktop app that does the bookkeeping, Agency ships as a .deb, an .rpm and an AppImage for x86_64 and arm64.

This page gives the by-hand method first, then the install commands for Agency on Debian, Ubuntu, Fedora and Arch, then what is weaker on Linux than on macOS. Disclosure: Agency is ours, and this site is its home. The general method, with the reasoning behind each step, is in How to run coding agents in parallel.

Run agents in parallel on Linux by hand

Install git and tmux from your distribution if you do not have them, then run these from inside your repository (here called myapp, with a main branch). Each worktree is a second checkout in its own folder, so one agent cannot edit another's files.

1. Create a worktree and branch for each task

   git worktree add -b agent/fix-login ../myapp-fix-login main
   git worktree add -b agent/search ../myapp-search main

2. Start one agent per worktree in tmux

   Any agent CLI works, and they do not have to be the same one.

   tmux new-session -d -s agents -c "$PWD/../myapp-fix-login" claude
   tmux new-window -t agents -c "$PWD/../myapp-search" codex
   tmux attach -t agents

   Dependencies and untracked files such as .env are not in a fresh worktree, so set each one up before its agent starts.

3. Review, merge and clean up

   git diff main...agent/fix-login
   git merge agent/fix-login
   git worktree remove ../myapp-fix-login
   git branch -d agent/fix-login

Nothing in that list is specific to a distribution or a desktop, so it works the same over SSH on a server.

Install Agency on Linux

Agency is a free, open-source desktop app that runs the same agent CLIs in real terminals, each run in its own worktree. Every package comes for x86_64 and arm64; uname -m says which you have. As of 8 October 2026 the current release is 0.2.5. Install from a terminal, in the folder you downloaded to. The commands use the x86_64 names; on arm64, use the name of the file you downloaded. The files are on the download page.

Debian and Ubuntu

sudo apt install ./Agency_0.2.5_amd64.deb

Use apt rather than opening the file in Ubuntu's App Center, which can stall at "Installing" on a downloaded package. The arm64 file is Agency_0.2.5_arm64.deb.

Fedora

sudo dnf install ./Agency-0.2.5-1.x86_64.rpm

The arm64 file is Agency-0.2.5-1.aarch64.rpm.

Arch, and any other distribution

chmod +x Agency_0.2.5_amd64.AppImage
./Agency_0.2.5_amd64.AppImage

The arm64 file is Agency_0.2.5_aarch64.AppImage. The AppImage carries its own libraries and needs only FUSE from the system. If it stops with a libfuse error, install your distribution's FUSE package, or run it with APPIMAGE_EXTRACT_AND_RUN=1 set. It does not add itself to your application menu, and there is no AUR package yet.

apt and dnf fetch WebKitGTK and the other libraries Agency needs. A newer package installs over an older one the same way, and sudo apt remove agency or sudo dnf remove agency takes it out again. The packages are not signed.

Which Linux versions does it run on?

Any with glibc 2.34 or later, on x86_64 or arm64: Ubuntu 22.04, Debian 12 and anything newer, and current Fedora and Arch. The floor comes from the build machine. The packages are built on Ubuntu 22.04 (glibc 2.35) and the binary needs only GLIBC_2.34. A build made on a newer image once installed on Debian 12 and refused to start with version `GLIBC_2.39' not found, so the release pipeline pins the older image. The .deb declares libc6 (>= 2.34), so a system that is too old refuses the package instead of installing it and failing at launch. The .rpm cannot carry that version check. To see your glibc version, run ldd --version.

You also need git, and Agency offers to install it through your distribution's package manager if it is missing; the desktop asks for your password. You need at least one agent CLI on your PATH, which Agency can install for you (most install through npm, so those need Node). There is no account to create.

What is weaker on Linux than on macOS

• The tray shows how many agents are running in its tooltip, not beside the icon. The Linux tray has no title text to put a count in.
• Clicking a desktop notification does not open the run it was about. Agency cannot hear the click on Linux.
• The window has square corners and no compositor shadow, and its menus live in Agency's own title bar instead of the system menu bar.
• The packages are not signed, and there is no AUR package yet.

None of these stops you working, but you should know them before you choose.

Doing the same with Agency

Who should not use it: anyone on Windows, an Intel Mac or a distribution older than glibc 2.34, and anyone happy in tmux who runs one or two agents at a time. The steps above are all you need there.

Questions

Is there a desktop app for coding agents on Linux?

Yes. Agency runs on Linux as a .deb, an .rpm or an AppImage, for x86_64 and arm64. It is free and open source, and it needs no account.

Can I run Claude Code agents in parallel on Linux without an app?

Yes. Make a git worktree per task and start claude in each one, in tmux windows as shown above. Claude Code also has claude --worktree fix-login, which makes the worktree itself.
