AWS engineers have released Pizza Bot, an open-source tool that manages AI agent tasks through an email-style inbox rather than a live chat window, so users can delegate work and check back only when a response or decision is needed. The tool addresses a common frustration with chat-based AI assistants, which require users to stay present while a task is completed; instead, Pizza Bot organises agent communications into threads, sorting finished work into an "Unread" category and items needing a decision into "Action", much as a human colleague would report back only once there is something to discuss.

Named after Amazon's "two-pizza team" concept, the tool began as an internal Amazon project before being rebuilt for public release, with Amazon-specific skills and MCP servers stripped out. It runs locally on Windows, macOS and Linux, storing threads in local SQLite files and sending nothing off-device without permission; it can also run entirely offline using Ollama for open-weight models instead of cloud providers. Out of the box it supports file operations, task delegation to specialist agents, a sandboxed JavaScript interpreter, browser automation, and compatibility with Claude Code's .mcp.json files, though its developers stress it is unofficial, unsupported open-source software with no AWS service-level agreement.
