Free NON-CLOUD alternative to postman

I need a non-cloud alternative to postman, in that there is no requirement that the application requires the user to “login” or “signup” to use / access features.

I tried insomnia, however there is still an option to login, and it seems we cant even use “environments” without logging in. Without environments it seems I cant configure global settings, which means I would have to apply tokens to every request for some systems.

need a non-cloud solution. Other requirements below:

• API conversation to code would be nice (how you can convert api requests to python, curl, etc.)
• Ability to apply global settings across requests (like auth headers)
• Basic storage of requests, in hierarchy.
• Would be nice if I could use variables but not hard fast requirement.

Any recommendations?

Update: I actually decided to go with Insomnia. Seems to do everything I need. I was able to find a way to get global settings to work, its kind of messy but it works for now. This post details how to get it to work.
