URLColors
Description from store

This extension allows you to flag specified websites by highlighting the website with a custom colored border. This is especially useful for developers who run their web applications on many different environments and who are constantly switching between a dev, test, and production version of an app or database. Because the application may look the same on all environments, it's easy to accidentally do something on the production environment that shouldn't have been done.

With URL Colors, you can easily have the browser flag important websites for you by specifying a the keyword to match against the tab url, the border color, width, opacity, whether or not the border should blink, and the interval of blinking. The wildcard character (*) is now supported.

It also has a demo mode, or snooze mode, so you can shut if off while presenting for a specified period of time, without worrying about reactivating it later. It automatically turns back on for you!

Thanks to @dzoba for developing this with me!

I never leave reviews but this is so handy for dev/pre-prod/prod addresses. Thank you so much.

Raquel Redondo 2024-09-18

I am loving this extension. :) however I have a question: how can I set the border width without specifying the flash and timer properties?

James Holcomb 2024-08-18

The only extension I could find that actually worked.

Axel Calvet 2024-05-22

Great ! I always searched for that since colortabs was ko.

Phil Hershkowitz 2024-03-21

It is handy to separate and highlight test system tabs from production. Dead easy to use.

Nicolas Santos 2024-02-07

Plain, simple and very very useful regex would be nice 👍

Greet tool! Thank you :)

This is great when working with multiple environments. Tip: you can customize border size/opacity per site, so you can set your prod instance to super visible bright red border to prevent you from making a career-limiting mistake!

I've been using URLColors for many years because it's simple and effective.

Great idea, but this NEEDS regex or wildcard matching or (instructions as to how to enable) as it is only good for one url not a domain

Exactly as advertised, no messing around just works. Using in ChrEdge.

This is cool, but I'd love to just be able to say *.test and all .test sites have the border for local development. Adding them all individually is a pain when working on many projects.

For anybody involved in software development that uses multiple environments which run the same application this is the extension you need. It is simple and easily configurable while being both obvious and unobtrusive. Thank you!

Did not work for me. Instructions unclear : do we enter 10px or 10vw or just 10 ?? range of opacity 0 to 1 or 0 to 100?? Tried all of these and nothing works. Text in my keyword box is google, blue

This is an amazing extension. I have been looking for something like this for years. I don't know how many times I have endlessly refreshed a page, looking for my changes, only to realize that I'm on the live site. Thank you for making this!

Awesome app, works well, would be curious if there are any plans to include literal matching/regex or wildcards (eg *.domain.com) for environments that are using sub-domains. Eg: site.dev.domain.com (Dev) site.test.domain.com (Test) site.domain.com (Production) The above with the basic match this does would allow to match on: test.domain.com and dev.domain.com, but because prod is using the same domain, this would override the .dev and .test subdomains.
