Description
Share a message and files through one link that opens when you choose. Recipients see a countdown, then the reveal. Content is encrypted in your browser before upload. Set how long it stays available, and choose Standard or Timelock, which encrypts the key for a future drand release. Standard is free within 7 days and 1 MB. Anything beyond that is $3 per Postdate: Timelock, up to 100 MB, and dates up to a year away. Built for launch reveals, embargoes, surprises, and time capsules.

Could you build this?
Yes Browser-side cryptography, standard file hosting (like S3/Cloudflare R2), and integrating the public drand (Distributed Randomness Beacon) timelock encryption library can be wired together in a modern web app quickly.
