BurnPony vs Signal disappearing messages

A conversation, or a note.

Signal's disappearing messages are excellent, and if both people already have Signal, they answer most ephemerality needs. The comparison matters at the edges: what happens when the other person doesn't have Signal, shouldn't need an account, or only ever needs to receive one thing.

the short version

Signal for relationships; BurnPony for handoffs. Signal encrypts ongoing conversations with the best protocol in consumer messaging and can make whole threads disappear on a timer — but both ends need the app and a phone number. BurnPony is one sealed note to anyone with a browser: no app, no number, no account, burned after the views you allowed.

Honest tradeoffs.

Where Signal disappearing messages wins

  • The protocol. The double ratchet's forward secrecy and post-compromise security are properties BurnPony's one-shot model simply doesn't have. For ongoing conversations there is no better widely available cryptography.
  • Everything a relationship needs. Voice, video, groups, media, and disappearing timers on entire threads — BurnPony does exactly none of that, on purpose.
  • Deletion at both ends. When a Signal timer fires, both apps delete the message. BurnPony controls the server copy absolutely, but what a browser displayed is outside anyone's reach.
  • Scrutiny at scale. Signal is among the most audited consumer software on Earth.

Where BurnPony wins

  • The recipient needs nothing. No install, no registration, no phone number — a browser and the link. For the plumber, the client, or the relative who will never install a messenger, this is the entire ballgame.
  • No identifier joins you. Sending someone a Signal message ties your numbers together in a registration system. A BurnPony note creates no pairing, no contact entry, no account anywhere.
  • Precision ephemerality. Views and expiry are per note, chosen at creation, enforced by the server in the same transaction that serves the last read — not a client-side timer both parties must honor.
  • Nothing to confirm afterwards. Once burned or expired, the link is indistinguishable from one that never existed.

The verdict.

  • Choose Signal if you talk to this person more than once — its disappearing messages inside a properly ratcheted conversation are the right tool for relationships.
  • Choose BurnPony if this is a handoff, not a relationship: one secret, to someone who may have no messenger, no account, and no reason to register anywhere.
  • Use both if you're most people — Signal for the people in your life, BurnPony for the one-offs outside it.
