A powerful GUI app and Toolkit for Claude Code

Create custom agents, manage interactive Claude Code sessions, run secure background agents, and more.

Fork Notice — This is a fork of winfunc/opcode with Windows-specific fixes and improvements.

Changes from upstream

Fixed settings save failures — Tauri invoke errors were silently falling back to a read-only REST API, causing saves to fail with cryptic HTML parse errors. Errors now propagate directly.
Fixed console window flashing — All subprocess calls (binary discovery and Claude execution) now use CREATE_NO_WINDOW to prevent terminal windows from briefly appearing on Windows.
Fixed PATH-based binary validation — set_claude_binary_path now resolves commands via where/which so bare PATH names like claude.exe are accepted.
Fixed real-time streaming — Replaced dynamic require() with static ESM imports for the Tauri event listener, fixing messages only appearing after app restart.
Fixed Windows subprocess environment — Claude processes now inherit all environment variables on Windows (Node.js needs APPDATA, USERPROFILE, SYSTEMROOT, TEMP, etc.).
Improved error messages — Settings save errors now display the specific failure reason instead of a generic message.
Updated model names — Corrected outdated "Claude 4 Opus/Sonnet" to "Opus 4.6" and "Sonnet 4.5" with centralized definitions.
Bigger model/thinking selectors — Selector buttons now show full names ("Sonnet 4.5", "Opus 4.6", "Auto", "Think", etc.) instead of single-letter abbreviations.
Persistent selections — Model and thinking mode choices are saved to localStorage and restored on app restart.
Model label on responses — AI response bubbles now show which model was used under the Bot icon.
Compact result stats — The "Execution Complete" card is now a slim stats bar (cost, duration, turns, tokens) instead of duplicating the response text.
Deduplicated system init — "System Initialized" widget only appears once per conversation instead of on every message.
Permission prompt support — Default and Accept Edits permission modes now work via an MCP-based permission prompt pipeline. Write/modify operations show a dialog for user approval instead of being silently allowed or hanging.
Interactive AskUserQuestion support — When Claude asks clarifying questions via the AskUserQuestion tool, a step-wizard dialog appears with clickable option cards, single/multi-select, and free-text "Other" input. Claude pauses and waits for your answers before continuing. Works in all permission modes including Bypass Permissions.

🌟 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

Claude Code CLI: Install from Claude's official site

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

cd opcode

Install Frontend Dependencies

Build the Application

For Development (with hot reload)

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/

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

"cargo not found" error
- Ensure Rust is installed and ~/.cargo/bin is in your PATH
- Run source ~/.cargo/env or restart your terminal
Linux: "webkit2gtk not found" error
- Install the webkit2gtk development packages listed above
- On newer Ubuntu versions, you might need libwebkit2gtk-4.0-dev
Windows: "MSVC not found" error
- Install Visual Studio Build Tools with C++ support
- Restart your terminal after installation
"claude command not found" error
- Ensure Claude Code CLI is installed and in your PATH
- Test with claude --version
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/.
