Show HN: Pizza Bot – An inbox for AI agents that work in the background
Pizza Bot is an inbox for long-running AI work. Start or schedule a task, return
to your day, and let completed work collect in Unread while runs waiting for
your decision collect in Action. Agents keep working when you navigate away
or disconnect; the api-server process must remain running.
Pizza Bot uses a stateful DeepAgents/LangGraph runtime with the same React
experience in Electron and the browser. The desktop app, web app, and terminal
CLI all communicate with the api-server over HTTP/SSE.
Pizza Bot was developed at Amazon and is released under the Apache 2.0 license.
Installers for macOS (Intel and Apple silicon), Windows, and Linux (x64 and
arm64) are attached to every release, with a SHA256SUMS to
check a download against. The macOS builds are signed and notarized; the Linux
packages are not signed, so verify them against the checksums.
npm run dev starts the Vite frontend and Electron desktop shell. The shell
forks and supervises its own api-server, matching the packaged application's
process model. Configure a model under Settings > Providers before starting
a live run.
See Running from source for isolated data roots, browser and
CLI development, desktop packages, and remote backends.
A running api-server needs access to at least one model provider; HTTP clients
do not. Configure Amazon Bedrock, Anthropic, Google Gemini, OpenAI, OpenRouter,
or Ollama in Settings > Providers. Bedrock accepts an AWS profile, AWS
access keys, or a Bedrock API key, with an optional region override; otherwise
AWS_REGION or us-west-2 is used. Bedrock combines its native catalog with
the regional Mantle catalog and routes models through Converse, OpenAI
Responses or Chat Completions, or Anthropic Messages according to their
advertised API family.
OpenAI and Anthropic also accept custom base URLs for compatible endpoints;
OpenAI can explicitly select Responses or Chat Completions, and Anthropic
supports x-api-key or bearer authentication. Select a model with
PIZZA_MODEL=:. The desktop protects entered secrets with
Electron safeStorage; server configuration persists only environment-variable
references.
Add MCP servers from the UI or /.mcp.json. Add Agent Skills
under /skills, or install plugins that package MCP servers and
skills together. Skills become available after their declared tools are enabled
and connected. A custom skill can replace a Built-in or Plugin skill with the
same id without modifying the original; removing the customization reveals the
Built-in or Plugin version again. The Built-in Pizza Bot Guide can explain
features, suggest workflows, help with setup, and point to project documentation.
See Extending Pizza Bot for configuration, environment
references, skill authoring, approval gates, and plugin installation.
The production graph engine is isolated to packages/runtime-langgraph;
frontends consume protocol projections rather than importing runtime or model
bindings.
