in the last two years I have dedicated some my spare time to a side project called Resting.
Resting is a browser extension that permits to analyze and test HTTP and REST APIs.
The mission of Resting is to simplify daily work of developer in testing and analyzing HTTP/REST requests.
Resting takes inspiration from Postman with the goal to be light and focused on the management of saved requests.
It is a Open Source project hosted by Github and it is a community friendly project.
Here is the Github repository
I'm very interested in some feedback about the tool
