After testing countless others that either lacked features or tried to dazzle with needless AI, Yaak stands out as a true masterpiece. 🙌
Kos Komelin
Got fed up with bloated API clients, so gave @yaakapp a try. Removed others from my computer immediately after that.
Timothy Cole
I’m blown away by how much better it is than Postman or Insomnia. It’s fast, clean, and reliable, which has made managing our APIs effortless.
Alex Yumashev
Yaak is my new favorite REST client P.S. Ironically, made by the same guy who built Insomnia, sold it, now making a new one 🤣🤣
Kevin Cunningham
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.
