# Next Dev Loop

Find out whether your change works, not just whether it compiles

## What this does

Your Next.js change compiles and type-checks, but that is not the same as working. This checks how the app actually behaves while it is running, using both what Next.js reports and what the browser shows. You need a dev server already running. Reach for it right after editing app code.

### Top 3 things it does for you

- Confirm my change works in the running app
- Check runtime behavior after editing app code
- See what the browser and Next.js each report

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Next Dev Loop

This verifies how a Next.js app actually behaves at runtime after you edit app code. It is for confirming that a change really works, rather than that it compiles or passes type-checking.

It brings together two views: /_next/mcp for what Next.js sees, and agent-browser for what the browser sees.

## Questions

### Is Next Dev Loop safe to install?

AIR scanned this exact version of Next Dev Loop and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 865d623aaf58, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/next-dev-loop.
