VoidNote

Encrypted,
self-destructing
notes.

Encrypt in your browser, share a link. The server stores only ciphertext — the decryption key lives in the URL. When the recipient reads it, the note destroys itself.

  • AES-256-GCM encryption before upload
  • Notes stored without their keys; the key stays after the # and never reaches us
  • Self-destructs on view count or expiry — up to 7 days, or 30 with a free account
  • SDK for TypeScript, Python, Go, Rust, Zig, Java + CLI

Create a note — no sign-up How it works
Void Stream

Encrypted real-time
ephemeral
channels.

Open a live channel and pipe anything into it — deployment logs, credentials, structured data. Encrypted in the browser; the server relays only ciphertext. When the writer closes it, the channel is gone. Free with an account.

  • Encrypted in the browser — server relays ciphertext
  • Pipe any output: deployment logs, secrets, data
  • Auto-destroys when the writer closes the channel
  • Same SDK interface, every language — create, write, watch, close
