Visual Studio Code

code.visualstudio.com

Extensible code editor with debugging, extensions, and remote development.

Overview

Visual Studio Code is a free, open-source code editor that integrates AI agents directly into the development workflow. Agents can autonomously plan tasks, make code changes, run commands, and iterate until work is complete. You can run GitHub Copilot agents, custom agents, or third-party agents (from Anthropic, OpenAI, and others) locally or in the cloud, with any model of your choice.

The editor maintains full backward compatibility with existing extensions and supports the Model Context Protocol (MCP) for connecting agents to databases, APIs, and services. VS Code works across multiple surfaces—the editor, CLI, browser, and mobile—so you can start a task anywhere and finish it anywhere. Whether you need interactive in-the-loop development or async work handed off for review, agents adapt to your workflow.

Pros

Free and open source
Agents work across VS Code, CLI, browser, and mobile
Flexible agent choice—GitHub Copilot, custom, or third-party
Built-in MCP support for connecting to external services
Full-featured editor alongside agent capabilities
No setup required—works with GitHub account

Cons

GitHub Copilot requires a subscription or free plan (with restrictions)
AI features can be disabled but require explicit configuration
Performance impact depends on agent workload and model choice
Telemetry collection by default (can be disabled)

Use this if

You need a free, extensible code editor with built-in AI agent support, want to run agents locally or in the cloud, or need flexibility to use multiple AI providers and custom agents.

Skip this if

You prefer a lightweight editor without AI features, need a fully offline solution without telemetry, or require a code editor without agent orchestration capabilities.
