yaak is the best postman alternative i have ever used. it's feature rich and also looks so gorgeous
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.
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 like the feature where you can paste in curl examples and it formats it right into the client for use. The guy who made Insomnia started Yaak.
Yaak is the best API client out there 🔥 I love the clean simple UI which is not bloated but still does a lot ♥️ ... Syncs your workspace with Git 👏
My go-to tool for testing APIs as I build them. The interface is clean and much nicer to use than bloated alternatives like Insomnia and Postman.
Got fed up with bloated API clients, so gave @yaakapp a try. Removed others from my computer immediately after that.
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
I had been using postman then moved to bruno. Recently started using @yaakapp, I must say its very clean and superfast.
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 🤣🤣
I've been using @yaakapp for a while now, and I absolutely love it! If you need a https client for your desktop, go check it out
i finally started properly using Yaak today rather than just pasting curl requests in and it's a delightful piece of software.
Seems like @yaakapp is the first true replacement for Postman with feature parity ... Simple, fast, beautiful and NO LOGIN POPUPS 😫🥹
After testing countless others that either lacked features or tried to dazzle with needless AI, Yaak stands out as a true masterpiece. 🙌
When I was looking for a clean and simple API client a few months ago, I came across Yaak ... I just love clean UI and lack of clutter.
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.
Still not convinced?
Import an existing Postman, Insomnia, or OpenAPI collection and get started instantly.
