User reviews

Users appreciate Chrome Response Override for its quick and simple response modification capabilities during debugging, saving time without needing programming skills. However, many report serious issues: it only functions when DevTools are open, faces compatibility problems with recent Chrome APIs, often fails to appear in DevTools, and frequently triggers CORS errors. Numerous users found it unsuccessful in practice despite attempts to fix settings or patterns. Overall, while the extension offers useful features, stability and compatibility challenges hinder its reliability for many.
Pros
  • Allows quick search and replace in incoming JSON responses, aiding debugging without programming.
  • Works as expected when functional.
  • Simple and effective tool that can save time during debugging.
  • Unique functionality not easily found in paid extensions.
Cons
  • Only works when DevTools are open, limiting usability.
  • Compatibility issues with newer Chrome versions; chrome.tabs.getSelected deprecated causing failure to get TabID.
  • Does not show Response Override tab in DevTools for some users, leading to confusion on usage.
  • Frequently encounters CORS errors, blocking proper functionality.
  • In many cases, does not work at all; users report inability to save rules or replace responses despite troubleshooting.

Just awesome. I needed a quick search and replace in an incoming json, and in 5 minutes I could continue debugging. Stuff that paid extensions couldn't supply (requestly) and without any programming!

Works as expected!

It does the job, but unfortunately it only works when devtools are open, which makes it useless for me.
