For greenfield projects, evaluate both against your most important technical requirements.

For privacy-conscious developers and budget-sensitive individuals, Codeium is the stronger pick in 2026 — no-training default, generous free tier, broader IDE coverage, and a self-hosted Enterprise option. GitHub Copilot is the right pick when your team is already deep in the GitHub ecosystem on a Business or Enterprise plan, you value the OpenAI model quality, and you want platform-level features like PR summaries and Copilot Workspace. The privacy gap matters most for individuals: Copilot Individual may use your inputs while Codeium Individual does not.
