Maintenance, license and trust

  • The repository was last updated about 2 months ago, so opcode is actively maintained.
  • Our last check on 2026-10-17 found the source still online.
  • It is released under AGPL-3.0, a copyleft license: you can use it, but modified versions you distribute must carry the same license.
  • Its trust signals score 100/100, with no cautions. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

Frequently asked questions

How do I install opcode?
Run npx skills add winfunc/opcode. The install tabs above show the steps for each supported agent.
Which AI agents does opcode work with?
It is written for Claude Code and Cursor, as a CLAUDE.md file. Other agents that read the same format can often use it too.

🌟 Overview

opcode is a powerful desktop application that transforms how you interact with Claude Code. Built with Tauri 2, it provides a beautiful GUI for managing your Claude Code sessions, creating custom agents, tracking usage, and much more.

Think of opcode as your command center for Claude Code - bridging the gap between the command-line tool and a visual experience that makes AI-assisted development more intuitive and productive.

🚀 Installation

Prerequisites

Release Executables Will Be Published Soon

🔨 Build from Source

Prerequisites

Before building opcode from source, ensure you have the following installed:

System Requirements

  • Operating System: Windows 10/11, macOS 11+, or Linux (Ubuntu 20.04+)
  • RAM: Minimum 4GB (8GB recommended)
  • Storage: At least 1GB free space

Required Tools

  1. Rust (1.70.0 or later)

    # Install via rustup
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
    
  2. Bun (latest version)

    # Install bun
    curl -fsSL https://bun.sh/install | bash
    
  3. Git

    # Usually pre-installed, but if not:
    # Ubuntu/Debian: sudo apt install git
    # macOS: brew install git
    # Windows: Download from https://git-scm.com
    
  4. Claude Code CLI

Platform-Specific Dependencies

Linux (Ubuntu/Debian)

# Install system dependencies
sudo apt update
sudo apt install -y \
  libwebkit2gtk-4.1-dev \
  libgtk-3-dev \
  libayatana-appindicator3-dev \
  librsvg2-dev \
  patchelf \

xcode-select --install

# Install additional dependencies via Homebrew (optional)
brew install pkg-config

Windows

Build Steps

  1. Clone the Repository

    git clone https://github.com/getAsterisk/opcode.git
    cd opcode
    
  2. Install Frontend Dependencies

    bun install
    
  3. Build the Application

    For Development (with hot reload)

    bun run tauri dev
    

    For Production Build

    # Build the application
    bun run tauri build
    
    # The built executable will be in:
    # - Linux: src-tauri/target/release/
    # - macOS: src-tauri/target/release/
    # - Windows: src-tauri/target/release/
    
  4. Platform-Specific Build Options

    Debug Build (faster compilation, larger binary)

    bun run tauri build --debug
    

    Universal Binary for macOS (Intel + Apple Silicon)

    bun run tauri build --target universal-apple-darwin
    

Troubleshooting

Common Issues

  1. "cargo not found" error

    • Ensure Rust is installed and ~/.cargo/bin is in your PATH
    • Run source ~/.cargo/env or restart your terminal
  2. Linux: "webkit2gtk not found" error

    • Install the webkit2gtk development packages listed above
    • On newer Ubuntu versions, you might need libwebkit2gtk-4.0-dev
  3. Windows: "MSVC not found" error

    • Install Visual Studio Build Tools with C++ support
    • Restart your terminal after installation
  4. "claude command not found" error

    • Ensure Claude Code CLI is installed and in your PATH
    • Test with claude --version
  5. Build fails with "out of memory"

    • Try building with fewer parallel jobs: cargo build -j 2
    • Close other applications to free up RAM

Verify Your Build

After building, you can verify the application works:

# Run the built executable directly
# Linux/macOS
./src-tauri/target/release/opcode

# Windows
./src-tauri/target/release/opcode.exe

Build Artifacts

The build process creates several artifacts:

  • Executable: The main opcode application
  • Installers (when using tauri build):
    • .deb package (Linux)
    • .AppImage (Linux)
    • .dmg installer (macOS)
    • .msi installer (Windows)
    • .exe installer (Windows)

All artifacts are located in src-tauri/target/release/.

🛠️ Development

Tech Stack

  • Frontend: React 18 + TypeScript + Vite 6
  • Backend: Rust with Tauri 2
  • UI Framework: Tailwind CSS v4 + shadcn/ui
  • Database: SQLite (via rusqlite)
  • Package Manager: Bun
