Our verdict
Cline is an open-source autonomous agent for VS Code that plans and edits code, runs commands with your approval, and lets you bring your own AI model, though API costs can rise quickly. GitHub Copilot is an AI coding assistant built for GitHub-based teams, known for inline code completion, editor chat, and agent tasks that can open pull requests. They overlap in editor AI help, but Cline suits people who want a transparent, model-flexible agent, while Copilot suits teams already working in GitHub.
Pick Cline if you want an open-source agent in VS Code that asks approval for each step and lets you use your own model provider.
Pick GitHub Copilot if your team already works on GitHub and you want completions, editor chat, and pull request help in one tool.
