Pi

Pi is a minimalist, open-source terminal coding agent written in TypeScript. We see it as an appealing option for tinkerers and experimenters rather than a mainstream enterprise default. Pi is a bare-bones harness that is more customizable than a full agent such as OpenCode. It’s also easier to adapt than building a new agent with an agentic framework such as ADK, LangGraph or Mastra.

The project is still early and primarily maintainer-led, despite strong traction and active releases. Treat pi as an engineer-facing building block, not a complete enterprise platform with full guardrails and support.
