Visual Studio Code is a free, open-source editor by Microsoft. It is the most widely used editor today, with a vast ecosystem of extensions for almost every language, tool, and workflow.
Visual Studio Code was released by Microsoft in 2015 and has since become the dominant editor across most programming communities. It is free to download and use. The source code is open source; a build without Microsoft telemetry is available as VSCodium.
Ecosystem
VS Code's extension marketplace is vast and comprehensive, offering extensions for every major language, tool, and workflow including PHP linting, debugging with Xdebug, database GUIs, Git tooling, Docker, SFTP, SSH, and code formatting—most free, and this breadth is a major reason for VS Code's popularity.
Performance
VS Code is an Electron application that embeds a Chromium browser engine and Node.js runtime, making it flexible but resource-intensive compared to native editors, with slower startup and higher memory usage, though on modern hardware this is rarely noticeable; on older machines it can be more apparent.
AI integration
GitHub Copilot is the most tightly integrated AI coding assistant option in VS Code, developed by Microsoft/GitHub and built directly into the extension API, though it requires a paid subscription; Claude Code also offers an available plugin as an alternative.
Privacy
VS Code collects telemetry by default, including usage statistics and crash reports transmitted to Microsoft, though this can be disabled in the Telemetry settings; VSCodium provides an alternative build with telemetry removed entirely, and GitHub Copilot sends code context to GitHub's servers when active, so review its settings if you work with sensitive codebases.
Integration with fortrabbit
The MCP server registers into the user profile with one command, and GitHub Copilot agent mode picks the tools up from there — apps, environments, deployment logs, and creating an app or an environment:
