I made an unlimited free captcha service.
I used altcha before, but it only focuses on Pow which was kind of hard to figure out bots.
So,I made this service. It tests Pow+11 more stuff on your browser and updates every 10 minuites to stop new bots, is light, and easy to use! Maybe you should consider using this?
There's a test for this: sh.krl.kr/test
Hope this is great for you!

I have some exp with this domain, and thought of building something in the space.
The problem is you're competing vs Cloudflare, a huge incumbent who offers this for free (up to a point). So startups won't want your solution. Enterprises are out of question, too, for all sorts of reasons (security, GDPR, cost of change, etc).
It's a cool idea though, and I applaud you for building it.
Ps. In mobile its possible to accidentally zoom out of the website, width is not limited to screen size.
