You know, that panel of tools that allows you to do stuff like inspect the DOM and see network requests. How do the companies that make them refer to them?
- Chrome calls them DevTools.
- Edge calls them DevTools.
- Firefox calls them Developer Tools.
- Safari calls it the Web Inspector.
I think it's somewhat safe to generically refer to them as DevTools. Safari is the only browser that doesn't use that term, but I imagine even die-hard Safari users will know what you mean.
