Description

Pi is a streamlined terminal coding environment designed to seamlessly integrate with developer workflows rather than requiring developers to conform to its structure. It comes equipped with robust default settings while maintaining a compact size and extensive customization options, allowing users to enhance Pi through various extensions, skills, prompt templates, themes, and shareable packages sourced from npm or git. When a team requires a specific command, tool, provider, workflow, or UI modification, they can simply instruct Pi to create it, make adjustments on the fly, reload, and continue their work without interruption. Pi is versatile, offering support for interactive, print/JSON, RPC, and SDK modes, which enables it to function as a comprehensive terminal UI, a scriptable command interface, a JSON event stream, or an easily embeddable agent harness. It is compatible with over 15 providers and numerous models, including options like Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, Kimi For Coding, MiniMax, OpenRouter, Ollama, and other services, facilitating mid-session model switching to enhance flexibility and user experience. This adaptability makes Pi an invaluable tool for developers looking to tailor their coding environment to meet their specific needs.
