Hey, thanks for posting. I'm the creator of Yaak, so let me know if you have questions!
The app is really super clean, I like it a lot (compare to Bruno for instance, one of your "competitor"). I see in the README that "Yaak is open source, but only accepting contributions for bug fixes.". It's an understandable statement, but it seems that there is also no way to post issues on the GitHub repo. Is there any reason for this (people could post issues without ever wanting to contribute imo). Anyway good job, I hope you'll get some traction!
Impressive! This is awesome! Let's go Rust! Rustworthy!
