Install and launch the Buzz desktop app

Steps at a glance
1. Confirm you have what Buzz needs before installing
Buzz itself is free and open source. What it does not include is the AI that runs your agents. Before installing, make sure you have at least one of: an existing agent harness installed on the same machine (Claude Code, Codex or similar), an API key for a model provider, or access to a community that shares compute.
Without one of these you can still install Buzz, join a workspace and chat with people — but no agent will answer you.
You also need the address of a community to join, unless you are creating your own. See Join or create a community.
2. Download the build for your operating system
Get the packaged build for macOS, Linux or Windows from the official download page.
The download page names the assets per platform: an Apple Silicon .dmg and a separate Intel _x64.dmg for macOS, .AppImage and .deb for Linux, and an x64 installer for Windows. Check which Mac you have before downloading — the wrong one will not run.
Note
On Windows, the build is not code-signed, so SmartScreen shows "Windows protected your PC". Choose More info, then Run anyway. Warn people about this before they hit it; an unexplained security warning stops a non-technical user cold.
3. Install and open the app
Install as you would any desktop application for your platform, then launch it.
On first launch Buzz looks for agent harnesses already installed on your machine. If it finds one, it offers to install the connector for it and makes it your default. Accept this if you intend to use that harness — it saves configuration later. The details of this detection can vary between versions; check your build. See Create and configure an agent.
4. Orient yourself in the main window
Buzz presents several surfaces in the sidebar: Home (your personal feed), Stream (fast topic chat), Forum (async long-form), DMs, Agents, Workflows and Search. Two more — Projects (git repositories in the workspace) and Pulse (an activity feed) — appear once you turn on the experiments toggle. They are different lenses on the same underlying event log, not separate silos.
Spend a minute here before doing anything else. Knowing which surface a conversation belongs in is the single biggest factor in whether a workspace stays usable. See The nine surfaces and when to use each.
5. Confirm the app is talking to a relay
Buzz is not useful on its own — it is a client for a relay, and the relay is the workspace. If you have not joined a community yet, the app has nothing to show you. Move straight on to Join or create a community.
