OpenCode vs GitHub Copilot CLI: Features, Pricing and User Reviews 2026

OpenCode is a free, open source AI coding agent made for developers. It works in your terminal, as a desktop app, inside popular code editors, and through a local web interface.

You can talk to it in plain language to write new code, fix bugs, refactor messy code, and make sense of large codebases. Rather than just guessing, it explores your project first, plans the needed changes, and then uses tools such as file editing, search, and shell commands to finish the task.

It supports over seventy five AI model providers, from big paid services to free local models, so you can choose what fits your budget. Since it does not store your code or data, it also works well for privacy focused teams.

GitHub Copilot CLI brings GitHub's Copilot coding agent straight into your terminal. Instead of switching to an editor, you type a request and it can plan the work, edit files, run shell commands, and open pull requests on its own. It connects natively to GitHub, so it can read issues, work with branches, and manage pull requests without extra setup. You can pick from many AI models, including Claude, GPT, and Gemini options, and switch between them as needed. Plan mode lets you review a checklist before any changes happen, while autopilot mode moves faster with fewer stops. Every file change and command needs your approval first, so you stay in control throughout the process.
