Best AI Agent for VS Code 2026

For VS Code users there are two paths: install an extension (Cline, GitHub Copilot, Kilo Code, Continue) and keep your exact setup, or switch to a VS Code fork (Cursor, Windsurf) for deeper AI integration. Extensions preserve your workflow; forks rebuild the editor around AI and generally go further.

CursorFree tier / $20–200/mo
8.5

Technically a fork, not an extension — but it imports your VS Code settings, keybindings, and extensions in one click, and its AI integration is deeper than any extension can reach.

Frequently Asked Questions

Should I use a VS Code extension or switch to Cursor?

If your team mandates stock VS Code or you rely on a finely-tuned setup, use an extension — Copilot for convenience, Kilo Code or Continue for open source. If you're free to switch, Cursor's fork-level integration (tab completions, agent mode) is noticeably deeper than what extensions can do. Migration takes minutes since it imports your settings.

What's the best free AI extension for VS Code?

Cline is the category leader — open source, 5M+ installs, Plan/Act safety modes. Kilo Code and Continue are strong too: all three are open source, support multi-file editing, and let you choose the model — local, API key, or a flat-price plan. Copilot's free tier works too but caps completions and chat.

Do AI extensions slow VS Code down?

Completions add little overhead, but codebase indexing can be heavy on large monorepos — users report this most with Cursor and Windsurf (forks index aggressively). Extensions like Continue let you control what gets indexed.
