How to choose between DevTools, multi-device Chrome extensions, desktop apps, and real-device clouds.
Tool classes
- Chrome DevTools – single viewport + deep debugging
- MSIM – multi-device board inside Chrome
- Desktop apps – external multi-device workspaces
- BrowserStack-class clouds – real devices and broad coverage
Recommendation
Use MSIM for daily responsive overview, DevTools for inspection, and a device cloud when you need real-device certainty.
