What is Advanced REST Client (ARC)?

Cross platform API testing
Use ARC on any major platforms including Windows, MacOS and Linux.

Simplicity
Easy and clean user inteface helps you make test request faster.

Works with Google Drive
Store your requests and projects on Google Drive and share it with your team.

More data then other tools
ARC implements it’s own HTTP client that works directly on a socket. As a result you receive detailed information about request timings, redirects and even sent HTTP message body.

No more limitations
Unlike other tools, there’s no limitations for setting headers with the request or reading headers from the response. You can do more with ARC.

Native application
ARC as a native application is now more powerful. Use your system variables in the application UI as a regular variable.

Open source
More secure. If you are not familiar with "open source", it means this app is more secure. Because its code is publicly available for review and contributions on GitHub at https://github.com/advanced-rest-client/arc-electron

Said about Advanced REST Client (ARC) as an alternative

blurHY It has all features postman has, and it's modern

Positive comment • over 2 years ago • as an alternative to Postman

Postman

patheticcockroach Better features than Postman for my use case: I need full control over the headers, including the ability to remove them all, something which Postman doesn't allow to do (they add tons of junk headers)
