Why Developers Choose OpenCode

An agentic workflow built for complex repositories, not just simple scripts.

Universal Development Environment

Seamlessly switch between our powerful Terminal UI, standalone Desktop App, and native VS Code Extension without losing context.

LSP-Intelligence Engine

Deep integration with Language Server Protocols ensures code suggestions are type-safe, definition-aware, and virtually hallucination-free.

Parallel Agent Sessions

Run multiple autonomous agents simultaneously: let one refactor legacy code while you debug a new feature in another session.

Enterprise-Grade Privacy

A true Local-First architecture. Your intellectual property stays on your machine, with optional auditable share links for team collaboration.

Engineered for Control and Flexibility

Complete model neutrality, granular permissions, and an open stack you can trust.

100% Open Source & Auditable

Built in the open. Audit every line of the agent's logic, self-host the stack, or fork it to customize the workflow for your specific engineering culture.

Model Neutrality (BYOK)

Never get locked in. Bring Your Own Keys for Gemini 4 Pro, Claude 4.5, GPT-5, or connect to local LLMs via Ollama for offline coding.

Safe, Permissioned Autonomy

You are always in open control. Granular 'Allow/Ask/Deny' permissions prevent the agent from executing commands or editing sensitive files without approval.
