cate

English | Français | 简体中文 | Deutsch

An infinite canvas IDE for parallel coding agents.

Run Claude Code, Codex, or any agent CLI in a Cate terminal and the canvas becomes mission control: every terminal shows whether its agent is working, finished, or waiting on you, and Cate notifies you the moment one needs input. One click spins up a git worktree with its own colored territory on the canvas, so five agents on five branches stay five visibly separate workstreams instead of a pile of tabs.

Open a folder and it becomes a workspace. No config files.

Pst. Hey, you, join our stargazers :)

Install

Download a prebuilt release. Don't build from source for daily use.

On macOS you can also install with Homebrew:

brew install --cask cate

What's inside

• Agent-aware terminals. Claude Code, Codex, Cursor, Grok, OpenCode and Pi report turn start, turn end, and permission prompts, so each panel shows running / waiting / finished and pings you when it needs an answer.
• Agent sessions survive restarts. Reopen the project and terminals come back with their scrollback, each agent reattached with its own resume command.
• Worktrees for parallel branches. Type what you're working on and Cate creates the worktree and branch, off a local branch, a remote branch, or an open PR.
• Panels on a canvas or in a dock. Terminals, Monaco editors, browsers, PDF/image/DOCX viewers, extension webviews, nested canvases. Float, dock into tabs and splits, or detach into their own window. Layout persists per project.
• Git and search. Multi-repo source control, git badges in the file tree, side-by-side diffs, ripgrep search, and Cmd+K for commands, panels, and files.
• A CLI agents can call. In a Cate terminal, cate drives a browser panel, reads another terminal, opens files, manages panels.
• Local and remote are the same path. Point Cate at a host over SSH or WSL and terminals, git, search, and agents run there; editors, browser, and canvas stay local.

Press Cmd+K for everything else. All shortcuts are listed in docs/shortcuts.md and rebindable in Settings.

Extensions

Cate has an extension system for third-party panels (MCP servers, diagrams, and more), each served in its own isolated webview. Browse and build them in the companion repo: 0-AI-UG/cate-extensions.
