I've been building FullScreenLab a free, browser based collection of fullscreen tools that need no signup, no download, and no configuration. Open a tool, hit "Launch fullscreen," done.
It grew to 81 tools across 12 categories: focus timers (Pomodoro style), ambient lighting (ring light, softbox light for video calls), streamer overlays, podcast tools, screensavers, animated backgrounds, kids' learning screens, fun/scenery visuals, prank and fake update screens, and a small set of AI driven visualizations.
A few things I cared about while building it out:
Zero friction the whole point is that someone needs a fullscreen ring light or a Pomodoro timer right now, not after creating an account
Consistent fullscreen behavior across very different tool types a timer and an ambient light tool need to behave the same way when you hit fullscreen, even though they're visually nothing alike
Breadth over depth rather than one polished flagship tool, the bet was that bundling many small, genuinely useful fullscreen utilities in one place beats searching for 12 different single purpose sites
Curious if anyone else has built multi tool "utility bundle" sites like this how do you think about IA/navigation once the tool count gets into the dozens?
