Idea is Validated and I'm Selling this because I'm working on apps which are more important for me than this. I made this SaaS because everyone started hating Postman and I wanted a better Alternative. I vibecoded(not entirely) this SaaS on my own. I didn't marketed it heavy. Just listed in few sites and made launch posts and got valid reason to price it $299. I got feedbacks, I kept it improving daily. Now I want a worthy person to take the ownership and scale this project.
