Restler user reviews :

Best app, I needed it for my projects during development! Even though I can make a cli tool for it, but this app is even more easier, and it’s great! It supports everything that window fetch () does, so it’s the best app!

Kudos! Please accept my best wishes for the great app. I’ve tested many APIs and everything works well. There is one issue with the environment wherein when I define environment variables like url and try to use it in the API like {{url}}, it doesn’t resolve. Please resolve or let me know if there is any other work-around.

I love it but a little problem. When my response is an array it won’t show it as pretty I have to view raw

Identical to postman at the surface level, but still has some things to improve on e.g. import collections, import env

Working just fine on my phone.Very useful to do a health check of my APIs on cloud on the go . Exploring other parameters such as proxy , dns , cookies to see the results.

This is a good app but text input requires some correction. Couldn’t type while on lanscape mode its completely covered by keyboard keys.

Great app. Very helpful during API testing. No clutter or the sort. Nice experience

It is easy to use. Missing a pretty (JSON) feature for the response.

Perfect alternative for postman on mobile.

App is perfect for sending request

A more compact version of postman on your phone

Pretty good. I got a crash when getting a big response (about 20kb). A few things that I think it needs: JSON formatting of the response. The type of scroll bar that you can grab and pull up and down to scroll quicker. The ability to switch between base URLs, so that I can switch between making a request to dev, staging, production, etc.

old Collection api error before app updating i have many apis collection and all works good but after update latest version in my old collection apis works but when i click on my old api collection folder(only 2 folders error and other old api folder works) crashing app and stop. And i am using app version 1.0.0-beta8. Please solve fast i have no other option for testing api
Excellent app, gets the job done and has a nice UI. The only one complaint I have is that the app icon doesn’t fill the entire frame. It would be great if that can be fixed (on Android version 10).
Great, could be improved further. For example: – allowing copying of part of the response – ability to parse response and use it to populate variables in subsequent calls – ability to switch base url

  • Thanks for suggestions. The support to copy part of the response has been implemented in the version 0.10 of app. The others suggestions are in the plans for future releases.
It’s been very reliable, but for the past few days, the history does not delete. Storage permission is granted. Fixed with latest release @ 20191203

  • Thanks for report this issue. I fixed it and will release a new version soon.
