REST extensions for Chrome can reduce the time you spend on manually testing your web apps, but which are the best to use?

App testing takes a fair bit of the developers' time, especially since a lot of testing is done manually, which is very time-consuming. Luckily, various tools are available to help reduce the time spent on manually testing APIs, leaving you more time to spend on other areas of your app development.

Although there are many Chrome REST plugins available, knowing which ones are the best will save you a lot of time and effort that could be spent on testing the API of the apps you are developing.

Postman Interceptor

Postman Interceptor extension for Chrome browser

Postman Interceptor main features & specifications summary

  • Rating: 3/5
  • Browser compatibility: Chrome and other Chromium browsers
  • Pricing: Free to use, and there are paid packages as well
  • Feature: Postman Interceptor replaced the very popular Postman REST API tester for Chrome

Postman Interceptor pros & cons


  • Offline mode available
  • It can be used as early as when development starts
  • Automation features available


  • The reliability of the extension is an issue
  • You need to install Interceptor Bridge as well

Postman Interceptor has many packages on offer for teams of developers or businesses

The Postman Interceptor Chrome API tester is the latest version from the REST testing plugin giants that brought out Postman. Postman has long been one of the best REST API testers available for Chrome. However, this latest version does have some ways to go to be at the level of its predecessor.

Postman Interceptor lets you test your apps from the moment you start developing, thus saving you valuable time. The app also contains many useful features such as automation and sending headers without having to use a proxy - which is critical for API testing.

I was very excited to test this latest version from one of the best REST app testers for Chrome. Although the extension worked and did what it was supposed to, I was a little disappointed as it wasn't as easy to use as I thought it would be. The UI was quite complex. Also, I didn't particularly appreciate having to install another app to use this one.

Upon checking the reviews from other users, it was also apparent that the extension was quite unreliable, sometimes refusing to connect at all. Other reviews also commented that the new extension is much more challenging to use than the original. Similarly, a few of the users also commented that they did not like installing another app just to start using this plugin.

This REST API Chrome extension can record the call history of your testing project to a local storage device as well as the cloud. You can also create many different dynamic requests such as custom variables, security, and authorization. You can review the response and compare it to previous tests and results.

I found the Talend API Tester to be easy to use while not lacking any features needed to test REST APIs. I especially enjoyed the collaboration feature, which allowed me and my team to test the same API and compare our results. All in all, this is probably the best Chrome extension for API testing that I've come across.

I also looked at some of the reviews from other users. For the most part, the reviews were excellent. In a few cases, the users would ask for certain features, such as the ability to run multiple instances of the extension in different tabs or the ability to save to the cloud. All of these were answered by the developers and are now featured in the extension. It means a lot when the developers listen to their users and continue to improve their apps.

With YARC, you can easily save your favorites, which you can then import/export to new devices. These favorites are also synced automatically to your Google Drive.

The YARC Chrome plugin also keeps a history of your previous requests and responses so that you can use them for quick comparisons or rerun them. You are also able to choose from a range of headers or customize your own.

I enjoyed testing out the YARC Chrome extension. I found it to be a nice simple app with a very clean design. It did what I wanted it to do when testing some basic APIs. I only used JSON during my testing, so I cannot comment on how accurate the other syntax are. However, the app does say that they also support XML, HTML, and CSS.

I also looked through the user reviews, and while most users loved the simplicity of this extension, a few commented that it might not be helpful for large-scale testing. Also, a few comments said the support for syntax other than JSON is not available.

Frequently Asked Questions About REST Chrome Extensions

How Do I Know If an API Is Working?

The only way that you will know if your API is working is by testing it thoroughly. Here are a few things to bear in mind while testing:

  • Test for typical errors and expected results first
  • Test how well the system handles stress by adding a series of load tests
  • Test for failures
  • Conduct group tests by test category
  • Prioritize the API functionality calls to speed up testing

How Do I Test REST API in Chrome?

One of the easiest ways to start testing REST APIs in Chrome is by installing a REST client such as Talend or vREST. These plugins can help you to test the REST APIs you are working on. Once you have the extension you prefer, you can start sending requests and receiving responses that help you test the REST API. The extensions we recommended are all simple enough to use, even for beginners.

Why Is REST API Used?

One of the reasons that REST API are so popular is because they offer so much flexibility. Since the data is not tied to resources or methods, REST can handle multiple calls, return different calls, and even make structural changes.

What Is the Advantage of REST API Over SOAP?

REST is becoming more popular than its older counterpart, SOAP. There are a few reasons for this, the most important of which is that REST allows a greater variety of data formats, whereas SOAP only uses XML. Also, since REST is coupled with JSON, it is faster and easier to use the SOAP.

Are REST API and RESTful API the Same?

Yes, they are the same. REST API, also known as RESTful API, is an application programming interface that follows the REST architectural style and allows interaction with RESTful web services.

Bottom line

So much goes into developing new web apps. The testing alone can take days, sometimes even weeks. Google Chrome has a few good browser extensions available for you to test REST APIs in Chrome easily and conveniently to save yourself valuable hours.

Which one to use will depend greatly on your needs as a developer. You may gravitate towards the tried and tested heroes of REST API testing, such as Postman REST Client and Advanced REST Client. However, be aware that both have undergone some significant changes and no longer work in the same way they did.

Fear not, as there are still a few great plugins available, some even rival these older legends. If you require clients in both SOAP and REST, then Boomerang - SOAP and REST Client may be the ideal fit for you. If you require an extension that allows collaboration and also has a very responsive support team, then Talend is the way to go. And if you just need a simple, lightweight extension you can use for some basic API testing; then I can recommend vREST.

    I love Boomerang. I don’t think Boomerang is a new app. I have been using it since last 5 years.

    I used to use Chrome Extension for API testing but it’s very heavy.
    Nowadays I just use Nightingale, it’s very lightweight and feature is enough for me.
