It seems that way with a lot of REST clients for whatever reason.

It starts off as what we all want - a simple rest client, maybe storing environments and requests

Then companies start building more features to try and create a whole community or ecosystem

They start asking for account creation. Then team creation to share with your team. Then an enterprise plan. Then they gimp the original features and paywall them.

Looking at you, Postman, Insomnia, Thunderclient

Fuck Postman. curl 4 life.

For a lot of use cases I find .http files very convenient. Here is a documentation from Microsoft: https://learn.microsoft.com/en-us/aspnet/core/test/http-files?view=aspnetcore-8.0

There is some standard around the .http extension so they work in many IDEs and they can be implemented into CI pipelines. The Microsoft documentation should be enough, though, to get you started.
