Opencode: A Command-Line Tool That Connects All AI

Compared to Cursor🔗 or Windsurf🔗, the latest trend is the rise of lightweight command-line tools that let developers seamlessly integrate AI into their workflows—such as Claude Code🔗 、Gemini CLI🔗 and Codex🔗.

The problem is that new and more powerful models keep emerging:

1. Each vendor is unlikely to support competitors or local models.
2. Switching between models and adjusting configurations often feels fragmented.
3. As models continue to evolve, their performance gaps will narrow and costs will drop—making vendor independence increasingly crucial.

That’s where Opencode🔗 comes in as a great solution:

• 100% open source under the MIT license
• Vendor-agnostic by design
• Built-in support for LSP (Language Server Protocol)
• Focused on the terminal user interface (TUI) — created by Neovim users and the creator of terminal.shop

Before installing, you’ll need a modern Terminal Emulator🔗 for the best experience (I’m using Warp🔗)。Then, set up your models using opencode auth login. There’s a full doc page🔗 detailing how to configure each model provider.

Among the available options, Opencode Zen🔗 is a curated set of models tested and optimized by the Opencode team in direct collaboration with the developers of those models. This list represents the most reliable and fine-tuned options. Some models, such as Grok Code Fast 1 and Code Supernova, are released for free as part of Opencode’s testing program.

Opencode also includes features found in other CLIs:

• Agents Mode🔗
• MCP🔗
• compact🔗
