Questions & Answers

As answered by people managing WhiteScrn and Comapi.

Which are the primary technologies used for building your product?

WhiteScrn's answer

Built with Astro and SolidJS for a fast, mostly-static frontend, styled with Tailwind CSS, and deployed on Vercel.

What makes your product unique?

WhiteScrn's answer

WhiteScrn is a free, browser-based tool that turns your screen into a full-screen colored or light panel — no downloads, no installs, no sign-up. Beyond solid color screens, it includes practical variations like a broken-screen effect, novelty screens (like a DVD screensaver and hacker-terminal screen), and other display modes, all built to load instantly and work directly in any browser, on any device.

Why should a person choose your product over its competitors?

WhiteScrn's answer

WhiteScrn is fast, free, and frictionless — it opens straight into the tool with no ads blocking the screen, no account required, and no unnecessary steps. It covers a wider range of use cases than most simple "color screen" tools (lighting/photography fill light, screen testing, pranks, novelty effects) in one place, and each screen is a dedicated, SEO-clean page that loads quickly even on low-end devices or slow connections.

How would you describe the primary audience of your product?

WhiteScrn's answer

Everyday internet users looking for a quick practical tool — people using their phone or laptop screen as a makeshift light source (for photography, video calls, or makeup), people testing monitors/screens for dead pixels or backlight bleed, and casual users looking for fun novelty screens like the DVD bouncing logo or a "hacker" terminal effect for jokes and pranks.

What's the story behind your product?

WhiteScrn's answer

(This one's really yours to tell — I don't have the actual origin story. Want to give me a quick version — e.g., why you built it, what problem you noticed — and I'll turn it into a polished answer?)

Who are some of the biggest customers of your product?

WhiteScrn's answer

WhiteScrn is a free public utility rather than a subscription product, so it doesn't have traditional "customers" — instead, its reach comes from organic users and web coverage. It was featured on TrendHunter under its "browser-based light panels" angle, helping introduce the tool to a wider audience of everyday users and trend-watching sites.
