Every agent its own branch. Review the work in one place.

Run Claude Code, Codex or any agent CLI side by side, each in its own git worktree, then review the diff, edit the file and merge the pull request in the same tab.

The agents page, built in HTML from punk0's theme files. Theme: Catppuccin Latte

The punk0 way

punk0 keeps it simple. It organises the agents you already run and shows you their work.

A terminal window per agent, gone when it closes.: Tabs run inside punk0. Close or reload the browser and they keep running, then replay their recent output.
git worktree add by hand, cleanup later.: New workspace makes a worktree on its own branch under ~/.punk0. Deleting the workspace can remove the folder with git worktree remove.
Checking every terminal for an agent that is waiting.: The status bar counts agents that need you or are working, and the page title shows how many wait. Desktop notifications if you turn them on. Claude Code tabs report this through its hooks.
Opening the diff in another tool.: The changed files and their diff sit beside the terminal, and the full editor is one click away.
Which chat was that?: Chats lists the conversations Claude Code, Codex and OpenCode keep on disk, including ones started in another terminal, and resumes any of them in a tab.

One binary

Written in Go. No Electron, no Node, no cgo.

The real CLIs

Each agent is the unmodified CLI started in your shell, signed in as you. punk0 has no chat of its own.

Local

Listens on 127.0.0.1. Terminals are refused if it listens anywhere else, and requests from other host names are rejected.

Out of your repo

State lives in ~/.punk0. Repositories only get worktree registrations, and temporary refs/px0/* during a review.

Small on purpose

Other orchestrators are desktop apps that bring their own browser engine, a background daemon, and sometimes a chat pane and a sign-in. punk0 does one job, organising the agents you already run, and leaves the rest out.

Same job for each app: the flask repository as a project, one git worktree, two idle shell tabs. Median of 3 runs on one Linux machine (Ryzen 5 5600H, 22.8 GiB RAM), measured 2026-10-26. Memory is PSS of every process the app started, shells excluded. Orca and Paradev ship their own browser engine and their numbers include it; punk0 opens in the browser you already run, so its tab is listed separately (about 112 MiB, or 279 MiB if Chrome runs only for punk0). Paradev requires a GitHub or Google sign-in before it opens a project, so its numbers stop at the sign-in screen.
App	Startup to the project	Memory when idle	Download
punk0 0.1.0	0.64 s	55 MiB + about 112 MiB for its tab in your browser	17 MiB
Orca 1.4.241	2.00 s	563 MiB	234 MiB
Paradev 2.0.0 formerly Superset	1.97 s to the sign-in screen	450 MiB or more at the sign-in screen	470 MiB

From each project's own README and docs, and from what the apps did on first launch in the same test.

How it works

punk0 runs on your machine and serves one page at 127.0.0.1:7777. Everything hangs off three things.

Projects
A repository you add with punk0 ~/code/app. A second punk0 hands its folder to the one already running.
Workspaces
The project folder, a git worktree on a branch of its own, or a scratch folder for work with no repository.
Tabs
Your shell in a terminal, or an agent started in it: Claude Code, Codex, OpenCode, Antigravity or Cursor Agent.

What punk0 adds

Everything here is punk0's own layer on top of px0.

See which agent needs you

Claude Code tabs report working, needs you and idle. The counts sit in the status bar and the page title.

Find any chat again

Chats reads what Claude Code, Codex and OpenCode keep on disk, grouped by workspace, and resumes any conversation in a tab.

Tabs outlive the page

Reload and every tab reattaches with its recent output. Restart punk0 and a Claude Code tab resumes its own conversation.

A terminal idle for 30 minutes is stopped, never a Claude tab that is working or waiting. A folder's editor stops after 5 idle minutes and starts again on the next request.

See what each tab uses

The resource panel lists CPU and memory for every workspace, its editor, its language servers and each terminal, down to the agent inside it.

The agent beside your code

Every folder opens in a full editor with the workspace's terminals on its right. Select lines and hand them to an agent without copying anything.

Built on px0

punk0 is a fork of px0 by Arpit Bhayani. It keeps px0's editor, search, git and pull request review, and adds the agents layer above them. Everything in this section is px0's work.

Star px0 on GitHub px0.ai

Fuzzy everything

Files with Ctrl/Cmd+P, search in files with Ctrl/Cmd+Shift+F, symbols with Ctrl/Cmd+Shift+O.

Pull request review

punk0 <pr-url> checks the PR out as a worktree of your clone and diffs it against the merge base. GitHub, GitLab, Gitea and Bitbucket; comments, verdicts and merging with a token, read-only without one. Batch Apply hands the comments to your agent.

Git without leaving the page

Status in the tree, side-by-side diffs that highlight the change inside each line, hunk staging and a commit graph.

Language servers when you want them

Definitions, references and hover through 14 servers. Off until you turn them on for a folder; idle servers stop after 15 minutes.

Build from source

The installer fetches the latest release for your system. To build it yourself instead, you need Go 1.25 or later and Bun.

Each release ships binaries for Linux, macOS, Windows and the BSDs, with a checksums.txt to check them against.
