  • (2021-03-09) Nikita Tonkoshkur: Has everything I need to be able to test websocket server from multiple clients. Highly recommend.
  • (2021-03-09) Kacper: It's poor. Very nice design, card view is a masterpiece. But functionality is poor. That's it.
  • (2021-03-02) Meir Blumenfeld: The best!!!
  • (2021-02-03) Tanakorn Rojnirunchai: Great extension! It's very easy to use.
  • (2020-11-25) crong moimstone: Great!. I found it! Thanks.
  • (2020-08-04) Julien Heller: Can't set initial connection headers. When trying to file an issue, I noticed the GitHub link is broken. Since I can't see the code, I can no longer trust this extension.
  • (2020-03-06) Maxim Kornienko: Great app!
  • (2020-02-29) Hannibal: I the past days I tried quite all available websocket client extensions and finally I discovered this GREAT EXTENSION fitting all my develper's needs. That's the perfect tool for testing websockets (with raw or json payloads), create projects, collections of tests, tabbed connections and so.
  • (2020-02-02) Nate Tinkler: This was exactly what I needed to quickly test a new socket server I was bringing online. It plays nicely with localhost and so far has met my needs. Feels like a postman for sockets. I do a fair bit of extension development as well, and the zero permissions extension gets a BIG thumbs up.
