About

Pi is a minimal, terminal-based AI coding agent built to be endlessly customizable — you extend it with TypeScript modules, skills, prompt templates, and themes rather than accepting a sealed feature set. It supports 15+ model providers, tree-structured shareable sessions, and multiple integration modes (interactive TUI, print/JSON, RPC, and SDK).

What it can do

  • Generate and edit code from natural language prompts in an interactive terminal session

    Natural language coding instructions via TUIGenerated or modified source code

  • Extend the agent with custom TypeScript modules, skills, and packages

    TypeScript extension modules and skill definitionsCustomized agent behavior and new capabilities

  • Route requests across multiple AI model providers

    Model provider selection/configuration (15+ providers)AI-generated responses from the chosen provider

  • Create and manage tree-structured, shareable conversation sessions

    Session interactions and branching commandsShareable branched session history

  • Produce machine-readable output for scripting and automation

    Prompts or commands via print/JSON modePlain text or structured JSON responses

  • Integrate the agent into other programs via SDK and RPC

    Programmatic API/RPC callsAgent responses embedded in external applications

  • Apply custom prompt templates and themes to the agent

Why it made the leaderboard

If you're tired of opinionated coding-agent CLIs that lock you into their idea of sub-agents or plan mode, Pi lets you ask the agent to rewrite its own harness on the fly and hot-reload, plus it supports 15+ model providers and tree-structured shareable sessions. It's a good fit for developers who want to reshape their agent around their exact workflow rather than adapt to a fixed feature set.
