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
