Coffer
A locally-encrypted vault for the things you actually need to keep safe.
Passwords, crypto keys, API keys, recovery phrases, PINs, and personal notes — all in one SQLCipher-encrypted file on your machine. No cloud account. No sync server. No telemetry. Unlock with a master password, lock with a click or a timer.
Built for
Developers, traders, power users.
Anyone who wants a single private store for credentials and the long-form material a typical password manager doesn't handle well — wallet seed phrases, multi-line API keys, account recovery codes, sensitive notes.
AES-256 via SQLCipher
Industry-standard, open-source encryption. The same library trusted by serious security tools. No proprietary crypto.
One file. Local-only.
Your entire vault is a single encrypted database file on your disk. Bring your own backup strategy — copy it to a USB stick, sync it via Syncthing, anything you trust.
Defense in depth
Auto-lock on inactivity. Auto-clear clipboard after copy. Login throttling on failed unlocks. Vault returns to ciphertext on disk the moment it locks.
Fully themeable
Six built-in themes plus per-token overrides for everything from background to button colors. Make Coffer feel like the rest of your tools.
Native desktop
Qt 6 / C++ / QML. No browser, no Electron, no background daemon. Opens fast, runs lean, closes cleanly.
No accounts. No cloud.
Coffer doesn't know your name. There is no server to compromise. The only person with access to your vault is the person holding the master password.
