newcode 0.3.1

AI-powered code generation agent platform

NewCode

NewCode is an open-source, terminal-first AI coding agent for generating, editing, and reviewing code directly from your CLI.

It is maintained as a fork of code-puppy, with a more professional default UX and workflow-focused agent setup.

Why NewCode

NewCode is designed for practical software workflows in the terminal: inspect files, make edits, run commands, and iterate quickly with AI assistance.

Features

• Multi-provider model support (including OpenAI, Anthropic, Gemini, Cerebras, and compatible OpenAI-style endpoints)
• Terminal-first coding workflow (read/search/edit/delete files and run commands)
• Built-in agent system with a default coding agent and optional specialist workflows
• MCP (Model Context Protocol) integration and server management
• Interactive command-driven UX for model, agent, and settings management
• Session autosave/restore utilities
• Plugin/callback extensibility hooks

Quick start

1) Install

pip install newcode

Or with uv:

uv pip install newcode

2) Launch
