I had been using Postman[1] for the last year or so and it's recently undergone a big update too which includes syncing. I've just tried Paw and like it more because:
- Native Mac app (it's prettier)
- I like the 3 pane window structure
- A lot of smaller UX things are nicer like duplicating, Postman annoyingly scrolls down, having to explicitly hit save, etc.
- Extensions
- Dynamic values
- Completions
Postman has the following which Paw lacks AFAIK:
- Collection automation and testing
- Chrome integration
- Dark UI theme
If I had use either of the 2 above I would not be able to switch over to Paw.
