Devin vs GitHub Copilot
Devin is Cognition's AI software engineer, with cloud agents and a desktop coding app; GitHub Copilot is GitHub's AI coding assistant with an agent mode in the editor and a cloud agent that opens pull requests. GitHub Copilot is cheaper to start: GitHub Copilot Pro costs USD 10 a month, Devin Pro USD 20 a month.
Choose Devin for software teams that hand coding tickets to an agent inside their own repositories, and GitHub Copilot for developers who want an agent inside their editor and their GitHub workflow. If you need browser games, presentations and documents as well, Siteglade, an autonomous AI agent with its own computer in the cloud, is a third option.
