AWS Introduces Pizza Bot: Open Source Inbox for AI Agents

Amazon Web Services (AWS) has introduced Pizza Bot, an open-source tool licensed under Apache 2.0 designed to act as an inbox for managing background AI agents. The application provides desktop builds for macOS, Windows, and Linux, along with browser and terminal clients that connect to either a local or standalone backend.

Task organization within Pizza Bot is structured into sections including All for thread history, Unread for completed work awaiting review, and Action for tasks paused for approval or answers. Users can organize threads into folders, inspect delegated workers in the Activity panel, and initiate tasks manually, through cron schedules, or via webhooks.

The server manages scheduling, ensuring that after downtime, missed cron intervals result in a single catch-up run rather than replaying every missed interval. Trigger occurrences are also recorded durably to maintain system reliability and traceability.

From an architectural standpoint, the application leverages DeepAgents and LangGraph for stateful execution, backed by a Hono API server that handles runtime and storage. Electron and browser clients share a React interface, communicating with the server over HTTP and server-sent events. LangGraph checkpoints preserve thread state and approval pauses, while separate SQLite stores maintain cross-thread memory and application metadata.

For AI integration, Pizza Bot supports multiple providers including Amazon Bedrock, Anthropic, Google Gemini, OpenAI, OpenRouter, and Ollama, which must be configured under Settings > Providers before executing tasks. Furthermore, the agent features scratch-file operations and a sandboxed JavaScript interpreter without network or host-filesystem access.
