AionUi: One Interface for 12+ AI Agents — A Free, Open-Source Cowork Desktop App

Tue, 07 Apr 2026 11:03:00 +0800

You’ve got Claude Code installed. Also Codex. Maybe Qwen Code for Chinese-language tasks. Each tool gets its own terminal window, MCP configs are duplicated across tools, and conversation history is scattered everywhere.

AionUi tackles exactly this: one desktop app that brings all your AI agents under a single interface. Free, open-source, Apache 2.0 licensed.

What It Does

AionUi is a cross-platform desktop app built with Electron + React, supporting macOS, Windows, and Linux. Its core purpose is unified management of multiple AI coding agents.

Supported Agents

AionUi auto-detects CLI tools installed on your machine. Currently supported:

Claude Code, Codex, Qwen Code, Goose AI, OpenClaw, Augment Code
iFlow CLI, CodeBuddy, Kimi CLI, OpenCode, Factory Droid, GitHub Copilot

Over 12 agents total. No extra configuration needed — install the CLI and it shows up in AionUi. If you don’t have any CLI tools installed, AionUi has its own built-in agent that works with Google login or API key authentication.

20+ Model Platforms

Wide model selection:

Major platforms: Gemini, Claude, OpenAI
Cloud: AWS Bedrock
Chinese platforms: Dashscope (Qwen), Zhipu, Moonshot (Kimi), Baidu Qianfan, Tencent Hunyuan, ModelScope
Local models: Ollama, LM Studio

If you’re in mainland China and can’t easily access OpenAI or Claude APIs, just switch to Dashscope or Zhipu. For fully offline work, run Ollama with local models.

Configure MCP Once, Sync Everywhere

This is the most practical design choice. Configure MCP (Model Context Protocol) tools once in AionUi, and all agents sync automatically. No more maintaining separate mcp.json files for each agent — change it in one place, it applies everywhere.

12 Built-in Professional Assistants

AionUi isn’t just an agent launcher. It comes with 12 pre-built assistants:

Assistant	Purpose
Cowork	Automated task execution
PPTX Generator	Presentation creation
PDF to PPT	Format conversion
3D Game	Single-file game prototyping
UI/UX Pro Max	57 styles, 95 color palettes
Beautiful Mermaid	Flowcharts, sequence diagrams
Planning with Files	File-based project planning

The Office features (PPT, Word, Excel) are powered by OfficeCLI, producing editable .pptx, .docx, and .xlsx files — not PDF screenshots. PPT output even supports Morph transition animations.

Scheduled Tasks: 24/7 Automation

This feature is uncommon in agent tools. You can set up scheduled tasks using natural language, like “every morning at 9am, summarize yesterday’s Git commit log.” AionUi converts it to a cron expression and runs it automatically.

Each scheduled task is bound to a conversation, maintaining context. Results are sent back to the conversation window, and can also be pushed to Telegram, Lark (Feishu), or DingTalk.

Preview Panel

AionUi has a built-in file preview supporting many formats:

Documents: PDF, Word, Excel, PowerPoint
Code: 30+ languages with syntax highlighting
Images: PNG, JPG, SVG, WebP, and more
Markup: Markdown and HTML with live editing

It also tracks file changes, shows Git version history, and supports one-click rollback.

WebUI Remote Access

You don’t have to sit in front of your computer to use a desktop app. AionUi can serve a WebUI, accessible via QR code or password login from your phone or another computer. Supports both LAN and cross-network access.

Combined with Telegram, Lark, and DingTalk bot integration, you can send commands to AI agents from your phone and receive results in your chat groups.

Tech Stack

Layer	Technology
Framework	Electron
UI	React
CSS	UnoCSS
Build	Vite
Testing	Vitest + Playwright
Database	SQLite (local)
Language	TypeScript

All data is stored locally in SQLite — nothing gets uploaded to any server. With local models (Ollama), the entire workflow can run completely offline.

Installation

Download the installer for your platform from GitHub Releases. Homebrew is also supported on macOS.

Once installed, just open the app. If Claude Code or Codex is already on your machine, AionUi detects them automatically. Otherwise, use the built-in agent with an API key or Google login to get started.

Compared to Using Claude Code Alone

Claude Code is powerful, but it’s a terminal tool. AionUi doesn’t aim to replace it — it puts Claude Code alongside other agents in one managed workspace.

Key differences:

Multi-agent: Claude Code only runs Claude; AionUi runs multiple agents simultaneously
GUI: Full desktop interface with file preview, Office generation, and image processing built in
Scheduling: Claude Code has no built-in scheduling; AionUi runs tasks 24/7 automatically
Price: Claude Code requires API costs or a $100/month subscription; AionUi itself is free
Model choice: Not locked to one provider — 20+ platforms available

If you’re interested in the AI agent tool ecosystem, I previously wrote about CLI-Anything: A Universal Bridge for AI Agents to Operate Any Software, which approaches the problem from the opposite angle — wrapping existing software as CLIs for agents to call. AionUi takes the agent management perspective instead.

Current State

AionUi is iterating rapidly, with 4,400+ commits on GitHub. The community is active on Discord (English) and WeChat groups (Chinese).

One caveat: while the star count is impressive, Electron apps typically have significant memory overhead. If you only use one agent, running the CLI in a terminal is lighter weight. AionUi’s value shows when you genuinely need multiple agents, want GUI management, or require scheduling and Office generation features.
