What is Opaal?

Opaal is a desktop application that lets you design multi-agent workflows visually and export them as structured prompts for Claude Code and other agentic AI launchers. Instead of writing complex orchestration prompts by hand, you drag agent cards onto a canvas, configure their roles and skills, draw connections between them, and Opaal generates the prompt automatically.

Features

• Visual Workflow Canvas - Drag-and-drop agent cards with zoom, pan, and minimap
• 7 Agent Roles - Researcher, Architect, Developer, Reviewer, Tester, Documenter, Custom
• Smart Auto-Connections - Agents in adjacent phases connect automatically
• Manual Wiring - Override auto-connections with custom gradient-colored edges
• Live Prompt Preview - See your prompt update in real-time as you design
• 3 Starter Templates - Code Review, Feature Build, Bug Investigation
• Skills Integration - Auto-detects installed Claude Code skills from ~/.claude/skills
• Dark & Light Themes - Linear-inspired minimal aesthetic
• Save & Share - .opaal files for workflow portability
• Export to CLAUDE.md - One-click export for Claude Code and compatible platforms
• Skill Workshop - Create, edit, validate, and manage Claude Code skills with live preview
• Skill Viewer - Immersive read-only viewer for skill documentation
• Smart Templates - 5 skill templates with structured scaffolding
• Workflow Execution - Run workflows directly via Claude SDK integration
• Keyboard-Driven - Full shortcuts, undo/redo (50 levels), multi-select, control groups
• Context Menus - Right-click for quick actions on canvas and nodes
• Copy/Paste - Duplicate agents with connections preserved

Download

Download the latest release for your platform:

Platform	Download
Windows	Opaal.exe
macOS	Opaal.dmg
Linux	Opaal.AppImage

Windows users: Opaal is a portable app — no installation needed. Just download and run the .exe directly. The first launch may take a moment to unpack. Windows SmartScreen may show a warning since the app is not code-signed; click "More info" then "Run anyway" to proceed.

Or view all releases.

Quick Start

1. Open Opaal and pick a starter template (or start from scratch)
2. Add phases (columns) representing execution stages
3. Add agents with roles like Researcher, Developer, Reviewer
4. Configure each agent's skills, instructions, and expected output
5. View the prompt in the Prompt tab - it updates live
6. Copy or Export the prompt to use in Claude Code or your preferred AI launcher

How It Works

Visual Canvas  -->  Prompt Engine  -->  CLAUDE.md / Clipboard
(drag & drop)      (auto-generate)     (paste into your AI launcher)

Opaal converts your visual workflow into a structured natural-language prompt. Each agent becomes a section with its role, skills, inputs, outputs, and instructions. Connections define data flow. Columns define execution order (parallel within a column, sequential across columns).
