Hi HN, I made Pizza, an open-source, event-driven AI agent. No `while true`.

Each turn is a state machine. Conversations and tool calls go into an immutable SQLite log. The UI, model context, and session tree are built from that log.

The model gets one tool: a CLI. Reading files, editing code, and running commands all go through it.

You can keep a conversation going without manually starting new sessions. Pizza compacts context as needed, and you can branch from any earlier message.

Agents in separate workspaces talk through `tell`, each doing the work in its own project. An SSH host can be a workspace too: Pizza deploys itself there and runs remotely.

Desktop and terminal interfaces are included. Bring your own model.
