Check hurl out. Unlike bruno or Postman, it is free and blazingly fast. Define your requests in plain text format and commit them to your version control.
It also allows you to export your plain text hurl files as curl commands.
Was using Bruno and RapidAPI (fka MacPaw) locally, but they couldn't do conditional sequences properly. Switched to Postman, which could, despite knowing they kept everything on the cloud.
I left postman behind after the forced cloud integration, but admittedly, it is difficult to find something as simple and richly featured to replace it.
I ended up using a vs code extension called Thunder Client.
@lorty@webdev you ever run into issues/cases where a third-party you integrate with sends you a Postman collection and expects you to use it for testing?
Not from a third party, but I did have to adapt a lot of collections to use on Insomnia. It does allow importing from the postman v3 collection format, but it's a bit hit or miss on wether it works 100%. I had a few problems with sequential requests, but they were easy enough to fix in my case.
If it's just for testing, I'd try that. If they require Postman it for validation purposes, then there really isn't much you can do.
