Mix floating canvas panels with docked tabs and splits, detach panels into standalone windows, and keep multiple workspaces synced across sessions.\n\nOpen any folder to create a workspace — Cate restores your canvas layout, panel positions, and open terminals every time you come back. Right-click the canvas to add panels, press `Cmd+K`\n\nfor the command palette, or drag panels onto the dock to create tabs and splits.\n\nNo configuration files, no project setup — just point Cate at a directory and start working.\n\nAlt-tab works fine — until you have 12 terminals, 6 files open, docs in another window, and notes scattered across desktops. At that point switching windows becomes the actual bottleneck.\n\nCate replaces that pile of windows with **one persistent canvas per project**. Terminals, editors, browsers, and notes sit where you put them, grouped how you think about them, and they're still there when you come back the next day.\n\nCate is\n\nnot a window manager replacement. Tiling/scrolling WMs (Hyprland, Niri, GlazeWM, KDE) are great if you mainly want to arrange OS windows. Cate is a spatial canvas around a single project's tools — closer to Figma's infinite canvas than to a WM.\n\n**Infinite canvas**— zoom, pan, and arrange panels anywhere in freeform space. Pan with two-finger drag or right-click drag; zoom with`Cmd+scroll`\n\nor the canvas controls.**Dock system**— drag floating panels onto the dock to create tabs and splits. Each dock zone (center, left, right, bottom) can hold multiple tabs with type-colored icons.**Detached windows**— pull panels or full dock layouts into separate OS windows.** Saved layouts**— name, save, load, and delete canvas arrangements (nodes and regions) from an in-app modal (`Cmd+K → \"Saved Layouts…\"`\n\n).**Multi-workspace sessions**— keep several projects open and restore them on restart. Switch between workspaces from the sidebar.\n\n**Monaco Editor panels**— full VS Code-grade editing with syntax highlighting, multi-cursor, find/replace, diff support, and Markdown Preview/Source mode with GFM rendering. Scratch editors persist unsaved content across sessions.**Persistent editor buffers**— file-backed models are reused across panels, and scratch editor content persists with the session.** Document panels**— native canvas viewers for PDFs, DOCX files, and images, with file type detection backed by magic-byte checks.** Native terminals**— xterm.js with WebGL rendering, backed by`node-pty`\n\nPTYs rooted in the active workspace. Shell auto-detection with graceful fallback if the configured shell is unavailable.**Browser panels**— embedded webview panels for previewing documentation, dev servers, or any URL. Context-isolated with hardened security settings.\n\n**Git-aware file explorer**— file tree with live filesystem watching, tracked/untracked dimming, search, and copy/paste for files and folders with collision-safe renaming.**Source control sidebar**— stage/unstage, branch management, worktrees, commit history, and inline diff views. Git monitor polls and surfaces changes automatically.**Project-wide search**— full-text search across workspace files with instant results.\n\n**Pi Agent panel**— run an in-app coding agent powered by`@earendil-works/pi-agent-core`\n\n, with chat threads, per-chat model restore, and workspace-aware panel placement.**Provider auth & models**— connect OAuth providers such as Anthropic, OpenAI Codex, and GitHub Copilot, or API-key providers such as OpenAI, Google Gemini, OpenRouter, Groq, Mistral, DeepSeek, and more.**Marketplace & plan mode**— install Pi extensions from the marketplace and use Cate's bundled plan-mode helper for agent-guided implementation planning.\n\n**Canvas-wide search**(`Cmd+Shift+F`\n\n) — Spotlight-style overlay that searches workspace files, live terminal scrollback, and open panel titles/paths in one place. Recent-focus ranked results with colored type-tile icons.**Panel switcher**(`Ctrl+Space`\n\n) — compact keyboard overlay for jumping between open canvas panels and centering the selected node.**Command palette**(`Cmd+K`\n\n) — quick access to commands, open panels, and workspace files. Unified Spotlight-style chrome across all overlays.\n\n**Auto-save & session restore**— all panel state, positions, and open files persist automatically.** Optional macOS native window tabs**— group Cate windows in the system tab bar.** Auto-update checks**— checks GitHub releases and notifies when a new version is available.** Crash resilience**— Sentry diagnostics, session restore validation, shell fallback banners in the PTY, and guarded update/restart flows help prevent noisy or looping crash states.\n\nIf you just want to use Cate, download a prebuilt release — don't build from source. This repository currently targets **v1.0.3**.\n\n| Platform | Formats | Link |\n|---|---|---|\n| macOS | DMG, ZIP (`arm64` , `x64` ) |\n|\n\n`x64`\n\n)[Latest release](https://github.com/0-AI-UG/cate/releases/latest)`tar.gz`\n\n(`x64`\n\n)[Latest release](https://github.com/0-AI-UG/cate/releases/latest)\n\nmacOS note:release builds are notarized and configured for hardened runtime.

Filesystem access is scoped to registered workspace roots, browser panels use hardened webview settings with disabled node integration, and the updater falls back to opening the GitHub release page when a verified installer path is unavailable. Workspace-scoped `allowedRoots`\n\nvalidation prevents terminals from spawning outside approved directories.\n\n```\nsrc/\n├── agent/              # Embedded Pi coding-agent integration\n│   ├── main/           # Agent process manager, auth, marketplace, session files\n│   ├── renderer/       # Agent panel UI, chat thread, providers, model prefs\n│   └── extensions/     # Bundled Cate plan-mode Pi extension\n├── main/               # Electron main process\n│   ├── ipc/            # IPC handlers (filesystem, git, terminal, menu, drag)\n│   ├── analytics       # Update/app event analytics helpers\n│   ├── appContext      # Shared main-process app state\n│   ├── featureFlags    # Runtime feature flags\n│   ├── shellEnv        # Login-shell environment capture\n│   ├── shellResolver   # Shell path resolution with fallback chain\n│   ├── workspaceManager# Workspace lifecycle and session persistence\n│   ├── workspaceRoots  # Allowed-roots registration and validation\n│   ├── windowRegistry  # Window management (main, dock, detached)\n│   ├── webSecurity     # Webview hardening and CSP\n│   ├── auto-updater    # Update checks and release fetch\n│   ├── sentry          # Sentry integration\n│   ├── store           # electron-store persistence\n│   ├── jsonFileStore   # JSON-backed file persistence helpers\n│   ├── menu            # Application menu\n│   └── sessionTrust    # Session restore validation\n├── preload/            # Context-isolated bridge exposed to the renderer\n├── renderer/           # React 18 application\n│   ├── assets/         # Renderer images and asset declarations\n│   ├── canvas/         # Infinite canvas rendering, drag, resize, placement\n│   ├── docking/        # Tabs, splits, detached dock windows, drag/drop\n│   ├── drag/           # Cross-window drag-and-drop runtime and state\n│   ├── panels/         # Terminal, Editor, Browser, Document, Git, Explorer,\n│   │                   # Projects, Canvas panel registry/components\n│   ├── sidebar/        # Workspace, File Explorer, Source Control,\n│   │                   # Parallel Work, Project List, fileClipboard\n│   ├── dialogs/        # Saved layouts and post-update feedback dialogs\n│   ├── settings/       # Settings window sections and shortcut recorder\n│   ├── ui/             # CommandPalette, GlobalSearch, NodeSwitcher,\n│   │                   # WelcomePage, ShortcutHintOverlay\n│   ├── shells/         # Main, panel, and dock window shells\n│   ├── stores/         # Zustand stores (canvas, app, dock, settings,\n│   │                   # shortcut, status, ui, update, url prompt)\n│   ├── hooks/          # Custom React hooks (shortcuts, canvas interaction)\n│   ├── lib/            # Utilities (coordinates, routing, terminal registry)\n│   ├── workers/        # Monaco/editor workers\n│   └── styles/         # Tailwind/global styles\n└── shared/             # IPC channel definitions and shared TypeScript types\n```\n\n**Electron 41**— desktop shell (Chromium + Node.js)** React 18**— UI framework with functional components and hooks** Zustand 5**— lightweight state management (no Redux/Context)** Monaco Editor 0.52**— code editing (VS Code's editor component)** xterm.js 5.5 + node-pty 1.0**— terminal emulator with WebGL renderer**@earendil-works/pi packages**— embedded coding-agent runtime, provider auth, and extension marketplace** pdf.js + mammoth**— native PDF and DOCX document rendering** react-markdown + remark-gfm**— Markdown preview with GitHub Flavored Markdown** simple-git 3.27**— git operations** chokidar 4.0**— filesystem watching**@phosphor-icons/react**— app iconography** Tailwind CSS 3.4**— styling** electron-vite 5.0**— bundling with HMR** electron-builder 26**— packaging and distribution** electron-updater 6.8**— update checks** Sentry Electron 5**— crash reporting and diagnostics** Playwright**— end-to-end integration tests** Vitest**— unit test runner\n\nCate is under active development.
