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 :)

## 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. Shortcuts are 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](https://github.com/0-AI-UG/cate-extensions).
