Keep the useful context.
Old tool results are masked and context is compacted when needed, reducing what the model carries into the next turn.
Work happens in more than one place.
Keep your projects, conversations, and recurring work connected to the same agent.
Your remote machine is a workspace, too.
Connect over SSH. Pizza deploys the agent to the remote host, where it works with that project’s files and tools.
Talk where you already are.
Slack, Discord, Telegram, Lark, voice, and webhooks can all reach the same agent through the gateway.
Keep recurring work on schedule.
Schedule checks, summaries, and routine tasks. The persistent assistant can pick them up on a recurring schedule.

A few things you might wonder.
What is Pizza?
Pizza is an open-source AI agent with a desktop app and a command-line interface. It helps with code, research, writing, and tasks across connected apps.
Do I need a model subscription?
Bring an API key or a supported subscription login from your chosen model provider. Pizza itself is open source. Model usage and connected services may have their own costs.
Where does my data go?
Pizza keeps conversation history on your machine. When you use a model or connected app, the information needed for that task is sent to that provider. Review the code and choose the services you trust.
Can I use it from the terminal?
Yes. Install the command-line app with npm, then run pizza. The desktop and terminal use the same agent runtime.
Which computers are supported?
The current release provides macOS for Apple Silicon, Windows x64, and Linux x64 installers. Other architectures may require building from source. For macOS installation troubleshooting, see the release notes.
