Overview

About OpenCode

OpenCode is an MIT-licensed AI coding agent that reads, edits and runs code in your project from a terminal UI, a desktop app or an editor extension for VS Code, Cursor, Zed and others. It loads language servers automatically, can run several agent sessions on the same repository, and lets you share a link to any session. Models come from 75+ providers through Models.dev, including local ones, and you can sign in with a GitHub Copilot or ChatGPT Plus/Pro account instead of paying per token. The maker, Anomaly Innovations, also sells Zen, a pay-per-request gateway of models it has tested for agent work, and Go, a low-cost subscription to open-weight coding models; both work with other agents too.

Editorial verdict

Pros & cons of OpenCode

high confidence

OpenCode is the obvious pick for developers who want a Claude Code-style agent without being tied to one model vendor, and who are comfortable configuring providers themselves. Teams that want a single vendor contract, managed policy and support out of the box will find the enterprise side thinner than that of the big commercial agents.

Pros

MIT-licensed with a very large contributor base on GitHub
Runs in the terminal, as a desktop app and inside common editors
Works with 75+ providers, local models and existing Copilot or ChatGPT logins
Optional Zen and Go plans give curated models without separate provider accounts

Cons

Output quality depends heavily on which model and provider you configure
Go plans have per-model request caps that need checking against your workload
Enterprise terms are only available through a sales form

Best for

Developers who want to switch freely between Claude, GPT, Gemini and open-weight models
Users who already pay for GitHub Copilot or ChatGPT Plus and want an agent on top
Privacy-sensitive teams that need an agent which does not store code or context
