AWS engineers have published an open-source AI agent management tool. It treats tasks and permission requests just like emails that fill up an inbox. The project was announced on AWS open-source blog last week. Its developers billed it as a way to more easily manage agent tasks without constantly checking a chat window.
Developers wrote that nobody sends an email and then watches the outbox until a reply lands. Pizza Bot uses an email client format because a thread is a unit of work you return to rather than a session you must attend. The software organizes communications with AI agents into message threads. Finished tasks and detailed result writeups land in the Unread category. Anything needing a decision goes to the Action category.
Asynchronous communication helps users balance multiple tasks assigned to digital delegees. Live chat assumes both parties are present. That assumption breaks down when a task takes several minutes. Pizza Bot treats an agent the way you treat a colleague who goes off to do work. It returns when there is something to read or a decision to make.
Pizza Bot takes its name from Amazon’s two-pizza team model, which refers to small, autonomous teams. The software began inside Amazon as an internal tool for non-coding AI agent uses. Non-coding uses continually required working in the background autonomously and only bugging the user when finished or asking a question.
The development team noted that chat windows do not match how people work. They found email to be the perfect design paradigm for internal use. They opened the project to open source contributions to see if it works for everyone else.
Pizza Bot is open source and available for Windows, macOS, and Linux from its GitHub repository. It runs on-device and stores all communication threads locally in SQLite files. It transmits nothing off device unless you grant permission. Prompts and attachments are sent to model providers, and the tool also supports Ollama for running compatible open-weight AI models locally.
Out of the box, Pizza Bot can list, read, write, edit, and search files. It can delegate tasks to specialist agents and run a sandboxed JavaScript interpreter. It ships with a browser automation skill and a guide skill. Claude Code-compatible .mcp.json files and skills are supported and can be dropped straight in.
Developers included a word of caution that this is open-source software and not an officially supported AWS product. There is no AWS support or service-level agreement behind it.
Users can snag a copy of the open-source software from its GitHub repository.
