Show HN: Pizza Bot – An inbox for AI agents that work in the background

Pizza Bot is an open-source inbox system for managing long-running AI agent tasks, allowing users to start work and return to it later while agents continue operating in the background. The platform supports multiple interfaces (desktop app, web app, and terminal CLI) that communicate with a central API server, and includes features like checkpointed runs, human-in-the-loop approvals, and integration with multiple AI model providers including OpenAI, Anthropic, and Google Gemini. Developed at Amazon and released under Apache 2.0 license, Pizza Bot organizes completed work and pending approvals into separate queues for efficient task management.
