An extension that lets you delay the response from specific URLs

URL Throttler
Description from store

Chrome Devtools allows you to throttle network speed across all network requests. However, if you want to slow down a specific URL while leaving others at normal speed, you're out of luck. Use this tool to achieve that. Install and specify the URL with a delay in milliseconds. Whenever the browser requests that URL, the response will be delayed by that amount of time. URLs not matching the ones you enter will behave as they normally would.

Would like the overview to describe why chrome flagged this extension as risky: "This extension may soon no longer be supported because it doesn't follow best practices for Chrome extensions." Other than that, it was exactly what I was looking for. Works great.

Fantastic!! I was looking for something to slow down loading of my CSS stylesheet and not the JS to test for FOUC (flash of unstyled content) and this one did the trick, thank you

Lol you just add a website and then it will magically do something apparently. No options at all no thanks.

Works just like a charm ;)
Ihor Syrov
Awesome extension. It helped me to debug an issue. Very easy to use!
Edmundo Elizondo
Good and simple, not bloated (unlike "Requestly"). Works if you need a delay working on your daily browsing. For development-time only, a similar extension "HTTP Request Blocker and Delayer" works only when DevTools panel is open; it also provides a bit more flexibility for each URL/rule (e.g. different delays). Blocking multiple/parallel requests seems to be a Chrome API limitation, see the GitHub page for the "HTTP Request Blocker and Delayer" extension. Use Firefox instead.
Роман Коцур
Unfortunately, the extension does not handle parallel requests. That is, if you set a mask for one domain, then get ready for all the styles, images, scripts, etc. will be processed one by one!
Marvin Xu
Works like a charm! But can I set different delay for different rules?

super useful for selective throttling, thanks

Sad that it has no option to set delays per request and also turn specific requests on and off, However it does its job.

Can be very powerful, I can imagine, but doesn't work when setup localhost as a host.

Worked really well. Thanks for this!

A totally cool and helpful extension that worked great initially, but after 10 minutes locked up Chrome (memory leak?) and then wouldn't open or work properly.

Does not work. I entered a website and told the extension to throttle for 5000ms, and the site never managed to load after 5(!) minutes, with the fan on my laptop going like crazy, and I could not even open the extension menu because it froze.

Can you add a functionality to sync rule across multiple browsers.

The filtering works great, however, the extension has some serious lag. When I try to type into the input fields, I don't see anything...until I close the box and click on the icon to show again, then I see what I type. If the address is long, and I try to click inside the input box and go to the end...it either takes 20 seconds for the cursor to get to the end, or it never does. All in all, this should is a must-have tool. I also agree with another reviewer that if they could allow individual URL's to have their own latency (instead of all of them, like now), it would be perfect (aside form the issues above)!

It just works! It's worth nothing that this tool supports string wildcards, so something like myapi.com/items/**/subitems will work

Great tool! thank you!!!

This is great, just one feature request. Would be possible also to add an option that this request will fail?

This is EXACTLY the tool I've been looking for for years, THANK YOU! It really lets you debug loading race conditions easily! My only other comment is that it would be nice to be able to set different throttle periods for different urls.
