Pi.dev

Pi.dev is a powerful, minimal terminal-based coding agent harness designed for developers, teams, and automation workflows. It provides multiple interaction modes including an interactive TUI, print/JSON output, RPC, and SDK integration, making it versatile for local development, scripting, inter-process communication, and embedding into larger systems. The platform supports a rich extension ecosystem built on TypeScript modules, skills, prompt templates, themes, and packages that can be installed via npm or git and shared as pi-packages. Authentication is handled through API keys and OAuth across 15+ providers, supporting hundreds of models from Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Hugging Face, and more, with mid-session model switching and custom provider configuration via models.json. Pi.dev excels at managing large conversations and codebases through session trees, auto-compaction summaries, dynamic context injection, and RAG/long-term memory primitives. Its skills and extensions expose tools, commands, keyboard shortcuts, events, and TUI components for advanced workflows including sub-agents, plan mode, permission gates, SSH/sandbox execution, and custom editor integration. The CLI offers comprehensive package management with install/update/list/configure commands, version pinning, test mode for repositories, message queuing and steering, and export/share options including HTML and GitHub Gist for reproducible agent workflows.
