Introduction

Opius is an open-source agentic workspace built for developers who work with multiple AI agents.

Instead of switching between terminal windows, browser tabs, chat interfaces, and standalone tools, Opius brings everything into a single desktop workspace.

Run multiple AI agents side by side. Manage terminals, skills, files, and workflows from one interface.

Whether you're building a feature, debugging a production issue, reviewing code, or exploring a large codebase, Opius helps you stay focused while your agents keep working.

Quick Start

Getting started with Opius takes only a few minutes.

1. Launch Opius

Open Opius from your Start Menu.

2. Create a Workspace

A workspace is your project environment.

Select a project folder and create a new workspace.

3. Add Agents

Choose the AI agents you want to use inside the workspace.

Examples:

  • Claude Code
  • Codex CLI
  • Cline
  • Aider
  • FreeBuff

4. Start Working

Your agents, terminals, skills, files, and project tools are now available from a single interface.

No more switching between multiple applications.

Workspaces

A workspace is the core unit of work in Opius.

Each workspace is built around a project directory and contains:

  • Agent assignments
  • Terminal sessions
  • Layout configuration
  • Installed skills
  • Project-specific settings

Workspaces are designed to keep everything related to a project in one place.

When you reopen a workspace, Opius restores your environment so you can continue where you left off.

Workspace Structure

Opius organizes development around a single workspace.

A workspace can include:

  • Multiple AI agents
  • Terminal sessions
  • Skills
  • File browsing
  • Notes
  • Tasks
  • Git tools

Everything stays connected to the same project directory.

Instead of managing separate applications, you manage a single workspace.

Agents

Opius is designed around CLI-based AI agents.

Each agent runs independently while remaining accessible from the same workspace.

Supported agents can be assigned to dedicated terminal slots and work in parallel.

Benefits include:

  • Multiple agents working simultaneously
  • Separate contexts per agent
  • Shared project visibility
  • Faster iteration across large tasks

You can assign different agents to different responsibilities.

Examples:

  • Claude Code for architecture and planning
  • Codex CLI for implementation
  • Cline for autonomous execution
  • Aider for code modifications

Supported Agents

Officially Tested

  • Claude Code
  • Codex CLI
  • Cline
  • Aider
  • FreeBuff

Experimental

  • Gemini CLI
  • Goose
  • Roo CLI
  • OpenHands

Additional CLI-based agents may work if they expose a terminal interface.

Support will continue expanding as the ecosystem evolves.

Skills

Skills are reusable workflows that help agents perform common tasks.

A skill packages instructions, workflows, and execution logic into a reusable unit.

Examples include:

  • Code review
  • Repository analysis
  • Documentation generation
  • Refactoring workflows
  • Project planning

Skills can be installed into a workspace and used by supported agents.

The goal is to make proven workflows reusable across projects.

Open Source

Opius is open source.

The project is developed publicly on GitHub and welcomes community contributions.

You can:

  • Report bugs
  • Suggest features
  • Contribute code
  • Improve documentation
  • Create skills
