The open source AI coding agent that runs in your terminal, desktop, or IDE.
In 2026, AI coding agents are everywhere. But most of them are proprietary, vendor-locked, and opinionated about which models you can use. OpenCode is different — it's the only agent that is:
- Fully open source (MIT License) — audit the code, contribute, fork it
- Model-agnostic — 75+ providers, bring any API key, use any model including local ones
- Editor-agnostic — terminal (TUI), desktop app, VS Code extension, or web UI
- Privacy-first — zero data retention, no training on your code, works in air-gapped environments
- Battle-tested — 185K+ GitHub stars, 900+ contributors, 7.5M+ monthly developers

Unlike Cursor, Copilot, or Claude Code — OpenCode's entire codebase is public on GitHub under the MIT license. You can inspect every line, run it on your own infrastructure, and never worry about vendor lock-in.
Most agents tie you to one company's models. OpenCode connects to 75+ LLM providers — Anthropic, OpenAI, Google, DeepSeek, GitHub Copilot, Azure, Bedrock, Ollama (local), LM Studio, Groq, Cerebras, and more. Use Claude, GPT, Gemini, DeepSeek, or run models locally. You're in control.
OpenCode runs where you code. Use it as a Terminal UI (TUI) with full keyboard navigation, as a desktop application (macOS, Windows, Linux), or as a VS Code extension. No browser tabs, no context switching.
Run multiple agents in parallel on the same project. Built-in agents include:
- Build — full-access agent for development work
- Plan — read-only agent for analysis and code exploration
- General — subagent for complex searches and multi-step tasks
- Explore — fast, read-only agent for codebase exploration
- Scout — external docs and dependency research
OpenCode automatically loads Language Server Protocol (LSP) servers for your project. The LLM gets real-time type information, diagnostics, and symbol resolution — making suggestions far more accurate than agents that only see raw text.
OpenCode stores none of your code or context data. It operates entirely on your machine. Enterprise deployments support SSO, on-premise operation, and internal AI gateways. No data leaves your environment unless you configure it to.
Hit Tab to switch between Plan mode (read-only analysis, no file changes) and Build mode (full execution). This two-step workflow means you review what the agent intends to do before it touches your code.

Go works with any coding agent, not just OpenCode. Use it as a provider in your favorite tool.
When someone you invite subscribes to OpenCode Go, you each receive a $5 credit on your account. It's a natural way to spread the tool among your team or community.
Zen is a pay-as-you-go model catalog where every model is tested and benchmarked specifically for coding agent workloads. No guessing which provider configuration works best — the OpenCode team validates each model-provider combination.
- Add $20 starting balance (auto-top-up at $5)
- Pay per request with zero markups
- All models US-hosted with zero-retention policies
- Works with any agent
- Set monthly spend limits
OpenCode publishes real-time model usage analytics — the most transparent data in the industry:
- #1 Model: DeepSeek V4 Flash (11T tokens processed)
- 137K+ daily unique users on Go
- 96% cache hit ratio across all models
- Top regions: China (17%), United States (12%), Brazil (5%), Germany (4%), Japan (4%)
