I wanted the tinyletter version of this. You write something, pick a photo, get a link; that's it. No account, no email wall and nothing to install. The recipient taps the link and the card opens with a little animation (flip, envelope, fold :D I (Claude) spent way too long getting the CSS 3D to feel right on mobile).
Built on Cloudflare Workers + D1, React Router 7, images from Unsplash. Free cards expire after 14 days. I added a $3.99 one-time premium if you want to schedule it: but the payment doesn't work right now :) ie didn't have a chance to hook up to Stripe yet.
I built this while my newborn son was sleeping next to me.
