Visual Studio Code is built with extensibility in mind. From the UI to the editing experience, almost every part of VS Code can be customized and enhanced through the Extension API. In fact, many core features of VS Code are built as extensions and use the same Extension API.Visual Studio Code is built with extensibility in mind.

Copilot agent mode is the next evolution in AI-assisted coding. Acting as an autonomous peer programmer, it performs multi-step coding tasks at your command — analyzing your codebase, reading relevant files, proposing file edits, and running terminal commands and tests. It responds to compile and lint errors, monitors terminal and test output, and auto-corrects in a loop until the task is completed. Available to all VS Code Insiders users today, and soon in VS Code Stable.
