OpenCode

OpenCode is an open source AI coding agent built by Anomaly, available under the MIT License. It runs in the terminal, as a desktop application, and as an IDE extension, letting developers work with AI assistance across their preferred environment. The project is hosted at github.com/anomalyco/opencode and the homepage reports over 160,000 GitHub stars, 900 contributors, and 13,000+ commits.

What It Is

OpenCode is a terminal-first AI coding agent that integrates directly into a developer's workflow without requiring a separate web interface. It connects to 75+ LLM providers through Models.dev — including Claude, GPT, Gemini, and local models — and also supports logging in with GitHub Copilot or ChatGPT Plus/Pro accounts to reuse existing subscriptions. The core product is open source under the MIT License, meaning the full source code is freely available to use, modify, and distribute.

How It Works

OpenCode ships with two built-in agents switchable via the Tab key:

• Build mode — the default, full-access agent for active development work
• Plan mode — a read-only agent for analysis and code exploration that denies file edits by default and asks permission before running bash commands

A general subagent handles complex searches and multistep tasks internally and can be invoked with @general in messages. The tool automatically loads the appropriate Language Server Protocol (LSP) configurations for the LLM, enabling context-aware code assistance. Developers can run multiple agents in parallel on the same project using multi-session support.

Deployment and Installation

OpenCode installs via a one-line curl script, npm/bun/pnpm/yarn, Homebrew (macOS and Linux), Chocolatey or Scoop (Windows), Arch Linux pacman/AUR, Mise, Nix, or Docker. A desktop application in beta is available for macOS (Apple Silicon and Intel), Windows, and Linux (.deb, .rpm, AppImage). The install script respects $OPENCODE_INSTALL_DIR, $XDG_BIN_DIR, and $HOME/bin for custom installation paths.

Privacy Architecture

OpenCode does not store any code or context data, which the enterprise page states allows it to operate in privacy-sensitive environments. The enterprise offering adds SSO integration and internal AI gateway support for organizations that want to deploy it at scale. No licensing restrictions or ownership claims are made on code produced with the tool.

Update: v1.18.1

The latest release as of July 2026 is v1.18.1, published on July 14, 2026. The project is under active development on the dev branch with frequent releases. A notable recent product addition is Tabs for Desktop, introduced to organize work and active sessions in the desktop beta app. The homepage also highlights OpenCode Zen, a curated set of AI models that the team has tested and benchmarked specifically for coding agents, available as a managed model access layer for users who want validated, consistent performance without managing provider API keys directly.

Open Source Adoption Signal

The homepage reports over 160,000 GitHub stars, 900 contributors, and 7.5 million monthly developers — figures published by the vendor. The GitHub repository shows 185,898 stars and 23,246 forks as of the latest crawl, with 4,672 open issues, reflecting a large and active community. The README is translated into 22 languages, indicating broad international adoption.
