AI reviewer that comments on GitHub and GitLab pull requests, triages them by risk and flags security issues
AI VS Code Extensions
25 tools in the catalog come as a VS Code extension; 17 of them have a free plan and 9 also offer an API. They are ranked by Effect score — how much each tool is used and rated, how widely it is listed elsewhere, and whether it is alive.
These AI coding tools install as Visual Studio Code extensions: completion as you type, chat about the open file, refactors across a codebase, or agents that edit files and run commands for you. Several editors are built on VS Code's open-source core and accept the same extensions, so one extension often works in more than one editor — check which marketplace it is published on.

What to check in a VS Code extension
- Decide how much autonomy you want: inline completion, chat, or an agent that edits and runs code. The further along that line, the more of its work you need to review.
- Check what code leaves your machine and whether it is kept or used for training; look for a setting or a plan that turns retention off.
- See which models it can use, and whether you can bring your own API key or a local model.
- Check the marketplace: Microsoft's for VS Code itself, Open VSX for most editors built on it.
