# AgentOne Desktop Is Now Open Source > Source: > Published: 2026-08-18 00:49:46+00:00 AgentOne is now open source. The entire desktop app is now free and open source under the **AGPL-3.0 license**, live on [GitHub](https://github.com/The-Best-Codes/agent-one). Every line of code, from the React frontend to the Rust/Tauri shell, is out in the open for anyone to read, run, fork, and improve. This has always been the plan. Today it's real. The AI ecosystem has an open-washing problem. "Open" models ship without weights, "free" tools turn out to be data farms, and "agents" turn out to be wrappers around someone else's API with a pretty UI bolted on. We want to be the exception. **AI that works for you should be auditable.** AgentOne is a desktop app that runs real work on your device. It reads your files, calls your tools, and talks to your models. If we're asking you to trust software like that, we should hand you the source code so you can see exactly what it does, and so you never have to take our word for it. Open source is the strongest guarantee we can give that AgentOne will stay free. The code can't be locked down, sold off, or turned into a subscription later. It's yours, permanently. **The best software is built in public.** Twenty thousand extensions, ten thousand models, one app that ties them together. The only way to make something this ambitious great is to let the community drive it. Bugs get caught faster, features get requested by people who actually use them, and the roadmap stops being a mystery. We believe AI agents should be an open standard, not a closed product. The full AgentOne desktop app, source and all: If you want a peek under the hood, the stack is React 19, TypeScript, Tailwind v4, Vite, and the Vercel AI SDK on the frontend, with a Rust backend that talks to SQLite. Simple, fast, and readable by design. Open source doesn't mean "everything costs us money is free forever." Two hosted pieces stay proprietary: These are paid infrastructure that keep the free plan running. The app itself, the thing you actually run on your computer, is 100% open, with no plans to change that. This is where you come in. And if you just want to use it: AgentOne is [free to download](https://www.agent-one.dev/download), no credit card required. Open source means you're not locked in, but we think you'll like it here. Here's to building the future of AI agents out in the open. 🎉 **AgentOne** · [agent-one.dev](https://www.agent-one.dev) · [GitHub](https://github.com/The-Best-Codes/agent-one)
