OJapp PWA-1P1A - Turn any web page into its own installable app

Hi Product Hunt! 👋 I built OJapp because I wanted to make PWA implementation simpler. Many websites and platforms let you edit HTML but do not let you upload or manage a separate manifest file. OJapp solves this by dynamically generating a Web App Manifest in the browser. You only need to add one lightweight script. I also wanted to improve the experience for users. Instead of treating an entire website as a single app, OJapp can turn individual pages—such as products, tools, articles, or profiles—into separate home screen apps with their own names and icons. My goal is to make PWAs easier to implement and more useful for the people who actually add them to their home screens. I’m a solo developer from Japan, and I’d really appreciate your feedback!
