Your secrets, encrypted before they leave your browser.

Poneglyph is a self-hosted vault for passwords, API keys, env vars, and notes. Encryption happens entirely on your device - the server only ever sees ciphertext.

Client-side encryption

Your master password derives the encryption key locally. The server stores only ciphertext.

Self-hosted

Run on your own infrastructure. Your data never touches a third-party cloud.

Zero-knowledge

The server cannot read your secrets - mathematically, not just by policy.
