What happened
Pizza Bot, a free self-hosted app for Windows, macOS and Linux, runs AI agents in the background and files finished work under "Unread" and approval requests under "Action", like an email inbox.
Why it matters
Users can start a task, open another conversation, and let the first keep running, so several jobs proceed in parallel instead of stalling unnoticed.
Summaries like this, every morning.
Pizza Bot is built for a practical annoyance: when several AI agents are asked to work at once, a paused approval or a finished job can go unnoticed, leaving the user idle. The app's answer is to treat agents like email threads, with "Unread" holding completed work and "Action" holding requests that need a person's decision, while an "Activity" view shows which specialist agents and tools are running in the background. It also adds scheduled runs through "Automations" and support for external services via Webhooks.
On Hacker News, reactions were mixed. One user praised the simple, clean interface and easy setup but admitted confusion over why an added MCP server did not work. Developer jd_ acknowledged that the relationship between Skills and sub-agents is hard to grasp without reading the documentation and said diagrams and per-Skill model selection are under consideration. That points to a tension common to extensible agent tools: the more capability packed in, the more the setup model needs explaining.
