  • (2021-04-22) Manit C: a lot better than postman or writing your own javascript.
  • (2020-10-17) Rahul Bali: Great. minimal and functional. no bulky installation for things that already exist in my computer. thank you for this extension.
  • (2020-10-14) Eugene Khoruzhenko: I am sure it will work great once I figure out how it works. I installed it, now what? The Overview says "It can..." do all the great stuff, but it does not say "Here is how you start it". Those screenshots look good, but how to I get there?
  • (2020-08-21) Jesse Furlan: This is exactly what I wanted! Ever since Postman moved over to native client (requiring cookie import for authentication), I've been looking for something better. With this extension I can just login to my website and fire off authenticated REST calls in the extension. Very slick. UI can use some cleaning up but they're just small minor issues.

  • (2021-03-31, v:4.4.0) Marco Salerno: Only Rester works!
    Hello, I can reach my wifi switch using its API. From RESTer works fine, but noto from any other place such as browser or Python requests.post. It's a mistery, likely I am doing something wrong. So you are the only my hope. The question is: is there any way to see the exact command RESTer send to the device? Maybe I am missing something.
