In our editorial scoring, GitHub Copilot leads in 4 of six categories (reliability, speed, value and ease of use), while Devin leads in 1 (autonomy). On price, Devin runs $20/mo entry + usage (acus) and is proprietary; GitHub Copilot runs $10-39/mo and is proprietary.
Devin is Cognition's fully autonomous software engineer: give it a task in Slack, Linear, or the web IDE and it plans, writes code, runs tests, and opens a pull request in its own cloud sandbox — including several sessions in parallel. It shines on well-scoped, repetitive engineering work (migrations, test coverage, small features) and improved markedly through its 2.x releases, but it remains weaker on ambiguous, novel tasks, and ACU-based usage pricing means heavy use costs real money. Cognition also acquired Windsurf in 2025, folding its IDE technology into the same product family.
GitHub Copilot is the most widely-adopted AI coding assistant. It offers inline code suggestions, chat-based assistance, and tight integration with the GitHub ecosystem including pull requests, issues, and Actions. Available in VS Code, JetBrains, Neovim, and more.
