OpenCode

Open source A.I. coding agent for your terminal, IDE or desktop

OpenCode is an open source A.I. coding agent. It helps you write and run code with any A.I. model. The site's footer credits "Anomaly".

You can use it as a terminal interface, a desktop app or an IDE extension. It comes with a set of free models you can try without creating an account. You can also connect other providers, such as OpenAI or Anthropic, or even local models. If you already pay for Claude Pro/Max, ChatGPT Plus/Pro or GitHub Copilot, the site says you can use those subscriptions too. To get started, the site points you to its intro in the docs.

What it does

Our take (opinion)

Best for

  • 💻 Developers who like working in the terminal but want a desktop or IDE option too
  • 🔄 People who already pay for Claude, ChatGPT or Copilot and want to reuse that plan
  • 🔓 Anyone who prefers open source tools under the MIT License

Watch out for

  • ⚠️ Connecting other providers may add costs, says the site
  • ⚠️ Data is stored when you use the free models, so read the privacy details first
  • ⚠️ It's built for people who write code, so beginners may face a learning curve
