Start a task from your phone, come back to a pull request
Route tasks to the desktop app from the Claude mobile app. Claude runs on your local machine and can open your apps, click through your UI, and test what it built. Now in research preview on Pro and Max plans.
Message Claude from your phone
Describe the bug, the feature, or the refactor. Claude picks up your codebase context where you left off.
Claude works on your local machine
It reads code in your local environment, writes changes, runs tests, and opens a PR. No setup or context files to select.
You get a working pull request
Not just a status update: a clean diff, passing tests, a ready-to-merge branch. You review, run CI, and decide what ships next.

OnboardingTriage issuesRefactor code
I'm new to this codebase. Can you explain it to me?
⏺ I'll analyze the Excalidraw codebase structure and provide a high-level overview.
⏺ Analyze(what: "Excalidraw codebase structure and provide a high-level overview of what it is, its main components, and how they're organized. Focus on understanding the project's purpose, architecture, and key features.")
Excalidraw is an open-source virtual whiteboard application with a hand-drawn style. It's designed for creating diagrams, wireframes, and collaborative drawings.
Purpose
- Web-based drawing tool with infinite canvas
- Hand-drawn aesthetic with support for shapes, arrows, text
- End-to-end encrypted collaboration
- Works offline as a PWA (Progressive Web App)
Architecture
The project is organized as a monorepo with these main components:
- Core Package (packages/excalidraw)
- React component library for embedding Excalidraw in any application
- Handles drawing, rendering, and core functionality
- Uses roughjs for the hand-drawn style
-
Includes export capabilities (PNG, SVG)
-
Web Application (excalidraw-app/)
- Full-featured web app at excalidraw.com
- Built on top of the core package
-
Adds collaboration features, local storage, sharing
-
Support Packages
- common - Shared utilities and constants
- element - Element manipulation and type definitions
- math - Mathematical functions for drawing
-
utils - General utility functions
-
Examples
- Integration examples (Next.js, browser script)
-
Shows how to embed Excalidraw in different environments
-
Documentation (dev-docs/)
- API documentation
- Integration guides
- Component documentation
Key Features
- Real-time collaboration with end-to-end encryption
- Export to various formats (PNG, SVG, JSON)
- Customizable drawing tools (rectangle, circle, arrows, freehand)
- Dark mode support
- Localization
- Library of shapes and components
- Arrow bindings and labels
- Image support
Technology Stack
- React for UI
- TypeScript for type safety
- Firebase for collaboration backend
- Jotai for state management
- Vite for development and building
- IndexedDB/LocalStorage for offline storage
The architecture allows for both using Excalidraw as a component in other applications and as a standalone web application with additional features.

What developers are saying
“Claude Code has dramatically accelerated our team's coding efficiency. I can now write EDA code in a notebook—pulling data, training a model, and evaluating it with basic metrics—and then ask Claude to convert that into a Metaflow pipeline. This process saves 1-2 days of routine (and often boring!) work per model.”
Anton Biryukov, Staff Software Engineer
“With Claude, we're not just automating customer service—we're elevating it to truly human quality. This lets support teams think more strategically about customer experience and what makes interactions genuinely valuable.”
Fergal Reid, VP of AI
“Claude Code is moving our team up a level: we decide what needs to happen, and smooth the process so it can build and verify end-to-end. A big part of my job now is to keep as many instances of Claude Code busy as possible.”
Simon Last, Co-founder
Connects with your favorite command line tools
Your terminal is where real work happens. Claude Code connects with the tools that power development—deployment, databases, monitoring, version control. Rather than adding another interface to juggle, it enhances your existing stack.
