I am already in love with it by using it for 5 min. This is insane!!! I shared it within my company and now I am going to evangelize Yaak to everyone 🥹

Just got my commercial license for @yaakapp and if you work with APIs I encourage you to do the same - it's the best postman replacement out there

First it was Postman, then insomnia was the new kid in the block, these two suckers got old and smell corpo from miles away, it is time now for yaak.app

I think this is my favourite for now. A clean and simple interface, focused on the core activities. It's local first and doesn't need an account.

Hey, I'm Greg 👋🏼

Having created and sold Insomnia in 2019, I didn't think I'd build another API client, but the tools changed for the worse and I found myself looking for something better.

I started over and built something I'm proud to put my name behind.
