The most widely deployed AI coding assistant
Visit GitHub Copilot →Copilot is the AI coding tool most developers meet first, largely because it installs as an extension into editors people already use rather than asking them to switch. It started as inline autocomplete and has grown into chat, multi-file editing and an agent that can take an issue and open a pull request.
Teams already on GitHub who want AI assistance without changing editors, and organisations that need enterprise administration and audit controls.
Less aggressive at whole-project edits than Cursor or Claude Code, and inline suggestions can be noisy in unfamiliar codebases.
Free tier with monthly completion limits; paid individual, business and enterprise plans.
If this is not the right fit, these are the closest options.
