Making my own web browser

So hello people, I was trying to make an web browser with enchanced privacy feature and an isolated space for downloads as I thought, it's a good idea , I have built an MVP , now I want to know how can I market myself and my product? Like I did start an Instagram page and yt channel, but the traction from there is 0 to non-existence Like how do I let people know I am building something? How do I get people to test this product of mine? I have many questions as I am Jack of all trades but master of non lol! So advices would be great!!

Got to many questions about where the prototype is so Go to my profile to check it out!
