What is the best Chrome REST client?

Representational state transfer (REST) is an architectural style for developing web services. RESTful web services use HTTP requests to access and use data. A REST client allows you to access REST web services and make HTTP requests easily.

With the right REST client, you can quickly test REST APIs without having to write code. This saves significant development time. In this article, we will look at the top REST clients available as Chrome extensions and help you pick the best one for your needs.

What is a REST Client?

A REST client is an application that allows you to send HTTP requests to REST web services. The main operations in REST are GET, POST, PUT, and DELETE. A good REST client will allow you to:

  • Make all types of HTTP requests including GET, POST, PUT, PATCH, and DELETE.
  • Set headers like Content-Type and Authorization.
  • Send parameters and body data.
  • Save commonly used requests for later use.
  • Display responses in a readable format.

A REST client with these features allows you to quickly test and interact with REST APIs without having to write client code. This simplifies API development and testing.

Why Use a Chrome REST Client?

There are many standalone apps and browser extensions for making REST calls. So why use a Chrome REST client specifically?

Here are some key advantages of using a Chrome REST extension:

  • Easy to access: It’s right there in your browser. You don’t have to install a separate app.
  • Cross-platform: Works on all platforms where you have Chrome installed.
  • Syncs across devices: Your saved requests sync across devices.
  • Works offline: REST clients work even without internet access. You can compose requests and access saved ones when offline.
  • DevTools integration: Some clients integrate with Chrome DevTools for debugging.
  • Free: Most good Chrome REST APIs are free to use with generous limits.

The convenience of accessing a REST client from your browser itself makes Chrome extensions the perfect choice for testing APIs during development.
