Learn how WheelOfSpins keeps data transfer and energy use low with in-browser rendering, lightweight pages, long-term caching, and a static hosting setup.
WheelOfSpins draws the wheel, its labels, and the spin animation locally with HTML5 Canvas. Spinning a wheel does not send a request to a server, so no data center has to process each spin, and the tool keeps working even on slow connections once the page has loaded.
Pages are pre-built so they load quickly. Scripts and styles are served with long-term cache headers, so returning visitors download very little again, and larger features such as PDF export are only downloaded when you use them. The site loads no advertising, video backgrounds, or third-party tracking scripts.
The site is served as static files by a managed hosting platform, so no always-on application server is needed to view pages or spin a wheel. Data is only stored on our servers when you choose to save a wheel to an account or create a share link. We do not claim carbon neutrality or publish emissions figures we cannot verify; instead we focus on sending less data and using fewer resources.
No. The spin happens entirely in your browser, so no server has to process it. Our servers are only used to deliver the page and, if you choose, to save or share wheels.
No. The site loads no advertising or third-party tracking scripts, which keeps CPU usage and battery drain low, especially on mobile devices.
Yes. Scripts, styles, and other build assets are cached by your browser for up to a year, so return visits download only what has changed.
