<p><a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="http://lans.cloud">lans.cloud</a> is a collection of 48 free single-purpose web tools. The classroom set — seating chart generator with keep-apart rules, fullscreen timer, random name picker, noise meter that never records, exam clock, spelling practice, reading fluency timer — all have genuinely ad-free fullscreen modes for projectors and smartboards. There are also crochet calculators (granny square blankets, yarn estimates), D&amp;D dice and stat rollers with exact probability tables, Minecraft build calculators, fitness timers, and developer utilities.</p><p>Everything runs in your browser: no accounts, no sign-up, and class lists or student names never touch a server. The tools are free and ad-supported, but ads never appear in the fullscreen presentation modes and never interrupt the tools. Several tools (wheel, timers, scoreboard, noise meter) can be embedded into class websites with a copy-paste snippet.</p>
