Not that I necessarily recommend yaak but this post explains why Bruno and Insomnia are not to be trusted: https://royathan.com/blog/the-api-client-hunt/

I would stay off Insomnia. A few versions ago, they practically took my local configuration ransom so they could force me to create a cloud account. Bruno is (still) not there, but the maintainers are slowly heading that way.

Insomnia has been around for a while but just like this post from a new account, there is a lot of push for bruno, which is usually a redflag. Never trust things that are "preached" for free.

if you use VS Code, there are a lot of alternatives:

[0]: https://marketplace.visualstudio.com/items?itemName=humao.re... - rest client storing config locally

[1]: https://marketplace.visualstudio.com/items?itemName=Christia...

[2]: https://marketplace.visualstudio.com/items?itemName=prawel.r... - same as [0], but with GUI

[3]: https://marketplace.visualstudio.com/items?itemName=slverma....

etc.

what is wrong with curl and httpie (I mean the open source cli one, no idea what the desktop one does)?

I think Insomnia and Bruno are both non-native JS apps, I think the moat here is that "this" is not "that".
