# Claude Desktop for Linux
This project was inspired by [k3d3's claude-desktop-linux-flake](https://github.com/k3d3/claude-desktop-linux-flake) and their [Reddit post](https://www.reddit.com/r/ClaudeAI/comments/1hgsmpq/i_successfully_ran_claude_desktop_natively_on/) about running Claude Desktop natively on Linux. Their work provided valuable insights into the application's structure and the native bindings implementation.
Supports MCP!

Supports the Ctrl+Alt+Space popup!

Supports the Tray menu! (Screenshot of running on KDE)

# Installation Options
## 1. Debian Package (New!)
For Debian-based distributions (Debian, Ubuntu, Linux Mint, MX Linux, etc.), you can build and install Claude Desktop using the provided build script:
```bash
# Clone this repository
git clone https://github.com/yourusername/claude-desktop-linux.git
cd claude-desktop-linux
# Build the package
sudo ./build-deb.sh
# The script will automatically:
# - Check for and install required dependencies
# - Download and extract resources from the Windows version
# - Create a proper Debian package
# - Guide you through installation
```
Requirements:
- Any Debian-based Linux distribution
- Node.js >= 12.0.0 and npm
- Root/sudo access for dependency installation
## 2. NixOS Implementation
For NixOS users, please refer to [k3d3's claude-desktop-linux-flake](https://github.com/k3d3/claude-desktop-linux-flake) repository. Their implementation is specifically designed for NixOS and provides the original Nix flake that inspired this project.
# How it works
Claude Desktop is an Electron application packaged as a Windows executable. Our build script performs several key operations to make it work on Linux:
1. Downloads and extracts the Windows installer
2. Unpacks the app.asar archive containing the application code
3. Replaces the Windows-specific native module with a Linux-compatible implementation
4. Repackages everything into a proper Debian package
The process works because Claude Desktop is largely cross-platform, with only one platform-specific component that needs replacement.
## The Native Module Challenge
The only platform-specific component is a native Node.js module called `claude-native-bindings`. This module provides system-level functionality like:
- Keyboard input handling
- Window management
- System tray integration
- Monitor information
Our build script replaces this Windows-specific module with a Linux-compatible implementation that:
1. Provides the same API surface to maintain compatibility
2. Implements keyboard handling using the correct key codes from the reference implementation
3. Stubs out unnecessary Windows-specific functionality
4. Maintains critical features like the Ctrl+Alt+Space popup and system tray
The replacement module is carefully designed to match the original API while providing Linux-native functionality where needed. This approach allows the rest of the application to run unmodified, believing it's still running on Windows.
## Build Process Details
> Note: The build script was generated by Claude (Anthropic) to help create a Linux-compatible version of Claude Desktop.
The build script (`build-deb.sh`) handles the entire process:
1. Checks for a Debian-based system and required dependencies
2. Downloads the official Windows installer
3. Extracts the application resources
4. Processes icons for Linux desktop integration
5. Unpacks and modifies the app.asar:
- Replaces the native module with our Linux version
- Updates keyboard key mappings
- Preserves all other functionality
6. Creates a proper Debian package with:
- Desktop entry for application menus
- System-wide icon integration
- Proper dependency management
- Post-install configuration
## Updating the Build Script
When a new version of Claude Desktop is released, simply update the `CLAUDE_DOWNLOAD_URL` constant at the top of `build-deb.sh` to point to the new installer. The script will handle everything else automatically.
# License
The build scripts in this repository, as well as `patchy-cnb`, are dual-licensed under the terms of the MIT license and the Apache License (Version 2.0).
See [LICENSE-MIT](LICENSE-MIT) and [LICENSE-APACHE](LICENSE-APACHE) for details.
The Claude Desktop application, not included in this repository, is likely covered by [Anthropic's Consumer Terms](https://www.anthropic.com/legal/consumer-terms).
## Contribution
Unless you explicitly state otherwise, any contribution intentionally submitted
for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any
additional terms or conditions.
