Bruno is open source; my company uses it for hitting API endpoints in different environments. It's easy to use and pick up. It's a great free alternative to Postman. It's relatively light on memory usage. You can bring your Postman Collections and OpenAPI collections to Bruno without any translation required. Review collected by and hosted on G2.com.
I don't like that you can't move the position of tabs in Bruno, so you constantly need to click on the left and right arrow buttons to navigate between tabs. There's also a slight problem that you can't search for variables in your environment - you need to manually scan a list to find your variable of choice. I also do not like the fact that Bruno collections often fail to get imported Review collected by and hosted on G2.com.
