well i was not aware of voiden but at first look it seems different in a few ways, the most obvious which might not be true but just my opinion is that Postchi has a better ux ( I think voiden is just the monako editor). it tries to understand the developer workflow, like allowing to set a base path on the folder level and a few other things like
1. envs are mapped to keyboard shortcut cmd + 1-9.
2. Open api docs can be imported using a url and kept in sync and provide auto complete and linting from
3. smaller things like, pinning a request to the top and then having the first pinned item attached to the shortcut shift+cmd+enter (works great for refreshing tokens)
4. all envs are stored in a single file
also voiden stores requests as text in a custom format not really readable (which is fine), Postchi however is pretty much the same http format plus a special @body to indicate where body starts.
Also i am planning to add a one month trial to the app so can be easier to see if it's for you or not
Actually changed my mind!, it will be free for personal use and paid for work. in the next update (next week latest) all features will be unlocked. if you end up trying it please share your feedback
