TL;DR - OpenCode 2026 Review

OpenCode stands out as the top open-source AI coding agent in 2026—terminal-native, privacy-first, and provider-agnostic. With massive community support (70k+ GitHub stars), multi-model flexibility, powerful tools/MCP/LSP, and dual Plan/Build agents, it's the ideal free & customizable alternative to Claude Code/Cursor for developers who value control and speed.

OpenCode Review Overview and Methodology

OpenCode is a powerful open-source AI coding agent that integrates directly into your terminal, IDE (VS Code, Cursor, etc.), or desktop app—allowing natural language driven code planning, generation, editing, debugging, and automation.

This 2026 review is based on real-world usage across multiple projects: building features, refactoring large codebases, multi-file edits, git operations, and testing with various models (Gemini, Claude, GPT, local) in terminal and IDE modes.
