OpenCode – Open Source AI Coding Agent for Terminal, IDE & Desktop

OpenCode is an open-source AI coding agent that helps developers write, understand, and refactor code efficiently in the terminal, IDE, or desktop environment. Supports 75+ LLM providers (including Claude, GPT, Gemini, local models, etc.), seamlessly integrates with existing GitHub Copilot or ChatGPT Plus accounts, and also offers built-in free models. Key features: LSP auto-loading, privacy-first (no code stored), multi-session parallelism, shareable links, diff preview, tool execution. Simple installation (one-line curl script), works with any editor. Used by 2.5M+ developers monthly, highly starred on GitHub, active open-source community. Ideal for developers seeking flexibility, privacy, and zero lock-in.

OpenCode – Open Source AI Coding Agent with Native Terminal Experience

OpenCode (https://opencode.ai/) is an open-source AI coding agent built by the SST team, now one of the top choices for terminal-based AI coding tools. It lets you "command" AI to modify real project code directly from the command line, just like using ChatGPT.

Key Highlights

• Multi-platform support: Terminal TUI (one of the best-looking terminal UIs), Beta desktop app (macOS/Windows/Linux), IDE extensions
• Full model freedom: Connect 75+ LLM providers (Models.dev), local models, free models, or use your existing Claude / GPT / Gemini / Copilot subscriptions
• Strong agentic capabilities: Understand project context, search files, suggest edits, auto-diff, run tests/commands, git commit, etc., with multi-agent parallel support
• Privacy & open source: Code is never uploaded or stored, local-first; active GitHub repo (many stars & contributors)
• Super simple installation:

  curl -fsSL https://opencode.ai/install | bash

  Copy

  Then run opencode, select model with /models, configure API key with /connect.

Use Cases

• Heavy terminal users wanting to break free from web-based Claude Code / Cursor limitations
• Enterprise/individual developers needing privacy protection
• Those wanting to use top models (e.g., Claude 3.5/4, Gemini 1.5/2, Llama 4) for complex refactoring, test generation, project initialization
• Developers tired of single-vendor lock-in

One-liner summary: OpenCode = "Claude Code / Cursor" in the terminal, but open-source + zero lock-in + more flexible. Highly recommended for all command-line-loving developers!
