Pizza Bot: Open-Source Inbox for Background AI Agents
A team of developers working at AWS recently open-sourced Pizza Bot, a self-hosted application designed to let AI agents run tasks in the background and return results through an inbox-style interface. Agents can perform scheduled or webhook-triggered work, delegate tasks to specialized workers, and pause for human approval when needed. By Renato Losio
AWS developers have released Pizza Bot, an open-source application that allows AI agents to autonomously perform tasks and return results through an inbox-style interface. This self-hosted tool provides users with an email-like inbox for managing long-running AI agent workflows.
Described by the creators as a developer-oriented solution, Pizza Bot focuses on the technical aspects while keeping the interface simple. The tool supports multiple model providers, MCP servers, and Agent Skills, while ensuring that data and agent state remain on the user’s machine.
AWS principal technologist Joseph Dolivo and solutions architect Igor Fil compare Pizza Bot to an email client, stating that just like emails, a thread in Pizza Bot is a unit of work that can be revisited rather than a session that requires continuous monitoring. The design of Pizza Bot is based on four key requirements: agents can inspect multiple sources, operate in the background, request approval before performing consequential actions, and notify users when work is finished.
The inbox interface organizes work into three queues: All, Unread, and Action, with an Activity panel displaying tasks delegated to specialist agents and their progress. Pizza Bot securely stores local data, including agent state, threads, checkpoints, attachments, and logs in a user-controlled folder, sending data only to the selected model provider and explicitly enabled MCP servers, with credentials stored in the OS secret store.
Dolivo and Fil emphasize that users have control over what leaves their machine, noting that data is sent to the chosen model provider and enabled MCP servers. In an early development phase, Dolivo recognized the project's potential, starting a side project called JoeBot in April 2025 to automate repetitive CRM logging tasks. The concept has since evolved into Pizza Bot, which has received positive feedback on Hacker News for its asynchronous inbox model and local-first architecture.
However, some users have questioned the project's relevance in an ecosystem of competing tools and its potential to replicate the success of AWS's internal skills and integrations. As a community-driven project, Pizza Bot operates without AWS support or service-level agreements, leaving developers responsible for maintaining, backing up, and updating the tool.
