How about a Chrome extension? Easy to use and maintain, run on any platform with Chrome.
I saw console app and even supreme site, can build UI in extension where you can save data and run on click.
I assume you need this for just single site?
ABOUT: Have authored 40+ extensions and chrome apps. You can check my profile reviews on same. Experience: new tab extension, bots, browser tweaks, deals & coupons, smart mail etc.
Open chat to discuss details.
