Hanzo Desktop
Build agents on your own machine
A window for making agents and letting them work together. Each one runs on a model you pick — local or on Hanzo Cloud — and what it touches stays on the machine unless you send it somewhere. macOS, Windows and Linux; 4GB of memory and 2GB of disk.
What you can build in it
Free and open source. Download it, and the first agent is a few minutes of clicking.
Nothing to scaffold
An agent is made in the window: give it a job, some tools, and a model. There is no project to create first and no file to check in before it exists.
Local model or cloud model, per agent
Point one agent at a model running on your machine and another at one on Hanzo Cloud. It is a setting on the agent, not a decision about the whole install.
They work together
Agents share context and hand steps to each other, so a job that needs several of them is one workflow instead of you copying between three chat windows.
It works with the network off
With a local model pinned, an agent keeps running when the connection goes. Nothing has to be uploaded for it to do its job.
Your keys stay on your machine
Keys and the data an agent touches stay local. An agent that has to pay for something spends from a key you hold, on hardware you own.
MCP is how it reaches your tools
Agents speak the Model Context Protocol, so a tool you have already connected elsewhere works here without a second integration written for this app.
Available everywhere you work
Native installers for macOS (Apple Silicon + Intel), Windows, and Linux.
Download it and build one
Pick a model, describe the job, hand it the tools. If the model is a local one, the whole thing runs without an account.
