Open When ♡ is my Replit Buildathon entry. Sealed letters for the moments you can't be there. The old tradition of "open when" envelopes, rebuilt as a tiny web app. You write letters for someone you love, seal each one with wax, and send a single link. They open each envelope only when its moment actually arrives. What's inside: A letter builder with preset moments (open when you miss me, open when you can't sleep) plus any moment you invent A cute pic step, taken right in the browser inside a heart shaped frame Wax seals in six colors that crack apart when a letter is finally opened An honor system pause before every reveal, asking if the moment is real Read receipts for the sender, you see the exact minute each seal broke A hand drawn heart, blushing gradients, and a full keepsake stationery design system Zero setup for remixing, no accounts, no API keys, Replit's built-in database with a SQLite fallback It works for couples, long distance friendships, a parent writing ahead for a kid's big days, or a time capsule to your future self. Try the demo bundle, one seal is already cracked so you can see both states openwhen--thekhushaldewra.replit.app/to/demo (http://openwhen--thekhushaldewra.replit.app/to/demo) Write your own in five minutes openwhen--thekhushaldewra.replit.app (http://openwhen--thekhushaldewra.replit.app) Built on one belief: the best time to say something isn't always now. #ReplitBuildathon
