## Intro

OpenCode is the open-source AI coding agent for the terminal with 140,000+ GitHub stars — one of the fastest-growing developer tools in 2025-2026. It features a TUI-first design with built-in LSP support, two agents (build for full dev access, plan for read-only analysis), and works with any LLM provider including Claude, OpenAI, Google, and local models. Best for developers who want an alternative to Claude Code or Codex that is fully open-source and provider-agnostic. Setup time: under 1 minute.
