Handy Chrome Extensions for Web Developers: Mobile Preview, Images & IP Info
Checking how a page looks on a phone, grabbing a batch of images off a site, and looking up an IP address are three small tasks that come up constantly for anyone building or debugging websites. A mobile preview chrome extension handles the first one without needing a physical device on your desk.
I've built extensions for all three of these small, recurring developer tasks.
A Mobile Preview Chrome Extension for Quick Checks
Responsive design bugs have a habit of only showing up on an actual phone screen, which isn't always within reach while you're coding, and browser devtools resizing doesn't always match real device behavior.
Mobile Preview Dev previews any webpage in mobile device views, built specifically for developers checking layout without switching to a physical phone or juggling multiple emulator windows. It's a fast way to sanity-check a responsive change before committing to it, whether that's a client site or your own project.
Pulling Images and Checking Network Details
Beyond layout, two other jobs come up often during development and debugging: collecting assets from a page, and confirming exactly what network information a site is seeing about a visitor.
Image Downloader downloads all images from any webpage with preview, filtering, and batch download capabilities, so you're not right-clicking and saving one file at a time. It's useful for pulling assets during development, checking what a competitor site is using, or just archiving a page's images quickly before it changes.
IP Info Viewer shows your IP address in multiple formats along with detailed network information and educational flashcards, handy for debugging network-related issues or explaining IP basics to someone learning the ropes. The flashcards are a small extra for anyone brushing up on networking fundamentals alongside their day-to-day debugging work.
These are three of my own extensions, each solving one narrow developer annoyance rather than trying to be a full devtools replacement. Install whichever matches what's slowing you down this week, and keep the others in mind for the next one.
