What is OpenCode.ai?
OpenCode.ai is an open source AI coding agent that helps developers write code directly in their terminal, IDE, or desktop application. Unlike proprietary AI coding assistants, OpenCode is completely open source, giving developers full control over their coding environment and data.
What sets OpenCode apart is its flexibility—it works with free models included out of the box, or you can connect any AI model from any provider, including Claude Pro, ChatGPT Plus/Pro, Gemini, and 75+ other LLM providers through Models.dev integration.

Installation & Setup
Getting started with OpenCode is straightforward. The installation process varies by platform:
Quick Install (All Platforms)
curl -fsSL https://opencode.ai/install | bashNPM Installation
npm install -g opencodeUsing Bun
bun install -g opencodeHomebrew (macOS/Linux)
brew install opencodeHow OpenCode Works
1. LSP Integration
One of OpenCode's standout features is its automatic Language Server Protocol (LSP) integration. When you start working on a project, OpenCode automatically detects the programming languages you're using and loads the appropriate LSP servers.
Why This Matters: LSP integration means the AI has deep understanding of your codebase—it knows about your types, functions, imports, and project structure. This enables more accurate code generation, better refactoring suggestions, and context-aware assistance.
2. Multi-Session Support
Unlike many AI coding assistants that limit you to a single conversation, OpenCode supports multiple concurrent sessions. This means you can:
- Work on multiple features simultaneously: Start separate agents for different parts of your project
- Compare different approaches: Test multiple solutions in parallel sessions
- Maintain context separation: Keep different conversations isolated for clarity
3. Model Provider Flexibility
OpenCode's architecture allows you to use virtually any LLM provider:
Free Models
OpenCode includes free models out of the box, so you can start using it immediately without any subscriptions.
Premium Subscriptions
Log in with your Anthropic or OpenAI account to use your Claude Pro, ChatGPT Plus, or Pro subscriptions directly.
75+ Providers
Connect to any model through Models.dev integration, including local models, custom fine-tuned models, and emerging providers.
Privacy-First Architecture
One of OpenCode's most important features is its privacy-first approach. Unlike many AI coding tools that send your code to external servers, OpenCode operates with a fundamental privacy guarantee:
No Code Storage
OpenCode does not store any of your code or context data. This means it can operate safely in privacy-sensitive environments, including enterprise codebases, healthcare applications, financial systems, and government projects.
Enterprise-Ready Privacy
For organizations with strict data governance requirements, OpenCode's privacy-first approach means:
- • No code leaves your environment (when using local models)
- • Compliance with GDPR, HIPAA, and other regulations
- • Safe for proprietary and confidential codebases
- • No vendor lock-in or data retention concerns
Available Platforms
Terminal Interface
Use OpenCode directly in your terminal for quick code generation, debugging, and refactoring. Perfect for command-line workflows and server environments.
Desktop App
Native desktop applications available in beta for macOS, Windows, and Linux. Provides a dedicated interface for AI-assisted coding with full project context.
IDE Extension
Integrate OpenCode directly into your favorite IDE (VS Code, IntelliJ, etc.) for seamless AI assistance within your development environment.
Zen: Optimized Models for Coding
OpenCode offers Zen, a service that provides access to a handpicked set of AI models that have been tested and benchmarked specifically for coding agents. This eliminates the guesswork of finding the right model for your coding tasks.
Why Zen Matters: With 75+ LLM providers available, choosing the right model can be overwhelming. Zen gives you access to validated models that OpenCode has tested specifically for coding tasks, ensuring consistent performance and quality across different providers.
Use Cases
Code Generation
Generate boilerplate code, implement functions from specifications, create test cases, and build entire features with AI assistance.
