Vaulted vs OneTimeSecret

Both let you share self-destructing secrets. The key difference: Vaulted encrypts in your browser before anything reaches the server. OneTimeSecret encrypts server-side — meaning the server sees your plaintext.

Key Differences

Vaulted encrypts in the browser using Web Crypto API, so the server never touches plaintext. OneTimeSecret encrypts server-side, meaning the service sees your data briefly before encrypting it. This matters if you want true zero-knowledge security.

Vaulted offers unlimited views or 1-10 configurable views, giving you flexibility for team sharing or reusable links. OneTimeSecret enforces single-view only — stricter burn-after-reading, but less practical for multi-person access.

OneTimeSecret is open source and self-hostable, which matters for compliance or regional data requirements. Vaulted prioritizes zero-knowledge encryption over self-hosting — you gain stronger privacy guarantees but lose the ability to run it on your own infrastructure.

Choose Vaulted if

  • You need true zero-knowledge encryption — the server never sees plaintext
  • You want unlimited views or a configurable view limit (up to 10)
  • You want a longer expiration window (up to 30 days)
  • Transparent cryptography matters to you (AES-256-GCM, documented)

Choose OneTimeSecret if

  • You need email read receipts — notifications when a secret is viewed
  • You need custom branding on shared links
  • You prefer an open-source solution you can self-host
  • Regional data storage is a compliance requirement
