Show HN: Pizza – An event-driven AI agent, no while true
Hi HN, I made Pizza, an open-source, event-driven AI agent. No `while true`. Each turn is a state machine. Conversations and tool calls go into an immutable SQLite log. The UI, model context, and session tree are built from that log. The model gets one tool: a CLI. Reading files, editing code, and running commands all go through it. You can keep a conversation going without manually starting new sessions. Pizza compacts context as needed, and you can branch from any earlier message. Agents in se

Version & cost evidence
Source votes: 2 votes (Nov 15, 2026 UTC; cumulative since publication) Recent records to compare: “Show HN: FlAIent – Learn interactive AI coding with real agents” (Hacker News, Nov 15, 2026); “Canvas by AgentGrid.io” (Product Hunt, Nov 15, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
