A powerful terminal-based AI assistant for developers, providing intelligent coding assistance directly in your terminal.

Overview

OpenCode is a Go-based CLI application that brings AI assistance to your terminal. It provides a TUI (Terminal User Interface) for interacting with various AI models to help with coding tasks, debugging, and more.

Features

• Interactive TUI: Built with Bubble Tea for a smooth terminal experience
• Multiple AI Providers: Support for OpenAI, Anthropic Claude, and Google Gemini models
• Session Management: Save and manage multiple conversation sessions
• Tool Integration: AI can execute commands, search files, and modify code
• Vim-like Editor: Integrated editor with Vim keybindings for text input
• Persistent Storage: SQLite database for storing conversations and sessions

Installation
