AgentOne is now open source.
The entire desktop app is now free and open source under the AGPL-3.0 license, live on GitHub. 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.
Why we did it
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.
What you're getting
The full AgentOne desktop app, source and all:
- 20,000+ built-in extensions via MCP: apps, services, and websites you can connect and command from inside a chat
- 10,000+ AI models from 70+ providers, powered by the AI Model Directory and updated every 24 hours
- Bring your own key with zero markup, or local models via Ollama and LM Studio, fully private
- Private by default: everything runs locally on your machine
- Built on Tauri 2: a lightweight Rust shell with a React 19 frontend, on Windows, macOS, and Linux
- Subagents, multi-chat, per-chat model config, MCP Apps, and a translated UI in six languages
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.
What stays closed (and why we're upfront about it)
Open source doesn't mean "everything costs us money is free forever." Two hosted pieces stay proprietary:
- The smart router API, our cloud service that keeps your requests flowing even when a provider goes down
- The extension registry (currently in private beta): a richer, Chrome-Web-Store-style way to discover MCP servers
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.
How to get involved
This is where you come in.
- ⭐ Star the repo: github.com/The-Best-Codes/agent-one
- 🐛 Open issues for bugs and feature requests
- 🔧 Submit a PR: contributions are welcome, from typo fixes to whole features
- 💬 Join the community: Discord and the forum are where the conversation happens
- 📖 Before contributing, skim our development philosophy: we keep the codebase simple and readable on purpose
And if you just want to use it: AgentOne is free to 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. 🎉
