Command your computer around the clock, drive an AI browser to complete tasks autonomously, with a friendly visual interface and full file management.
Write code, create presentations, research, draft reports, deploy servers, organize your desktop, automate browsers — if an Agent can do it, Halo supports it. Open source and free.
Our Philosophy: Wrap complex technology into intuitive human interaction.
Halo is powered by Claude Code and carries the same Agent capability.
The difference: Halo brings that capability out of the terminal — giving it a visual home, an always-ready interface, and a Digital Human system that can run autonomously in the background 7×24.
No command line knowledge required. No environment setup. No staring at a screen waiting. Download, install, run — then tell it what you want done.
|
Not just chat. Halo can actually do things — write code, create files, run commands, and iterate until the task is done. Isolated workspaces keep your projects organized. Each Space has its own files, conversations, and context. See every file AI creates in real-time. Preview code, HTML, images — all without leaving the app. |
Control your desktop Halo from your phone or any browser. Work from anywhere — even from a hospital bed (true story). Let AI control a real embedded browser. Web scraping, form filling, testing — all automated. Extend capabilities with Model Context Protocol. Compatible with Claude Desktop MCP servers. |
- Skills — Install skill packs for your Agent to extend what it can do
- Multi-provider Support — Anthropic, OpenAI, DeepSeek, and any OpenAI-compatible API
- Real-time Thinking — Watch AI's thought process as it works
- Dark/Light Themes — System-aware theming
- i18n Ready — English, Chinese, Spanish (more coming)
- Auto Updates — Stay current with one-click updates
Digital Humans are autonomous AI agents that work for you in the background — monitoring, summarizing, notifying, and acting — so you don't have to.
Browse and install them directly from the Halo Digital Human Store, no setup required.
Think of them like apps on your phone, except they work for you automatically.
Open the Store in Halo, pick a Digital Human, configure a few fields, and it starts running. No code, no prompts, no manual effort.
Examples of what Digital Humans can do for you:
- Monitor prices and alert you when a deal drops
- Deliver a daily news or market digest every morning
- Watch your inbox and summarize what matters
- Track social mentions of your brand or product
- Run reports on a schedule and send them to your team
Want to contribute a Digital Human to the ecosystem? Write a spec.yaml and submit a PR to the Digital Human Protocol (DHP) registry — the open-source store and protocol behind Halo's Digital Humans.
Your agent becomes available to all Halo users instantly after merge.
Remote Access: Control Halo from anywhere

- 100% Local — Your data never leaves your machine (except API calls)
- No Backend Required — Pure desktop client, use your own API keys
- Real Agent Loop — Tool execution, not just text generation
Powered by Claude Code — Thanks to Anthropic for building the most capable AI agent.
Halo isn't just for developers. We've seen:
- Finance teams building full-stack apps from scratch — with zero coding experience
- Content creators researching, writing, and organizing with AI in one flow
- Operations teams using Digital Humans to generate daily reports, monitor competitors, and summarize trends
- Designers prototyping interactive mockups
- Students learning to code with AI as their pair programmer
- Developers using the AI Browser for automated testing, scraping, and server deployment
The barrier isn't AI capability anymore. It's accessibility. Halo removes that barrier.
- Core Agent Loop with Claude Code SDK
- Space & Conversation management
- Artifact preview (Code, HTML, Images, Markdown)
- Remote Access (browser control)
- AI Browser (CDP-based)
- MCP Server support
- Skills system
- Digital Humans & Digital Human Store
- Plugin system
- Visual Git with AI-assisted review
- AI-powered file search
Halo is open source because AI should be accessible to everyone.

Inspired by [Halo](https://github.com/openkursar/hello-halo)
In October 2025, it started with a simple frustration: I wanted to use Claude Code, but I was stuck in meetings all day.
During boring meetings (we've all been there), I thought: What if I could control Claude Code on my home computer from my phone?
Then came another problem — my non-technical colleagues wanted to try Claude Code after seeing what it could do. But they got stuck at installation. "What's npm? How do I install Node.js?" Some spent days trying to figure it out.
So I built Halo for myself and my friends:
- Visual interface — no more staring at terminal output
- One-click install — no Node.js, no npm, just download and run
- Remote access — control from phone, tablet, or any browser
The first version took a few hours. Everything after that? 100% built by Halo itself. Since then, we've been using it 7×24.
AI building AI. Now in everyone's hands.
Made with ❤️ by our contributors.
If Halo helps you build something amazing, we'd love to hear about it.
