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.

So I started from scratch and built Yaak. If you liked the early days of Insomnia, you'll love Yaak.

Trusted by developers

See why others prefer Yaak over the alternatives.

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 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 now my first choice for API testing, light-weight yet powerful ✅ (powered by @TauriApps again)

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. 🙌
