pi is a TypeScript monorepo for building agents: an interactive coding-agent CLI (pi-coding-agent), an agent runtime with tool calling and state management (pi-agent-core), a unified multi-provider LLM API spanning OpenAI, Anthropic, and Google (pi-ai), and a terminal UI library with differential rendering (pi-tui). It deliberately ships no built-in permission system - it runs with the launching user's permissions - so for isolation you containerize it with Docker or a micro-VM. Reach for it when you want an extensible, self-hostable coding harness.
