I built a free password manager that looks and feels elegant and backs up to paper

#privacy #security #showdev #webdev

I've been building Peach for a while now. It's a zero-knowledge, local-first password manager — and it does a couple of things I haven't seen anywhere else.

No servers. Ever.

Your vault never touches a server. Encrypted on your device with AES-256-GCM and Argon2id key derivation and it stays there. Sync between your own devices is peer-to-peer over the Noise NK protocol. No hosted database to breach because there isn't one.

Codex

Print your entire encrypted vault as a grid of Aztec codes on paper that scales with vault size. Average vault will just be a few pages. Offline, air-gapped recovery that lives in a drawer.
I haven't seen another password manager do this. I think it's the right answer to the "what if I lose everything" problem.

The Inline Popup

Peach appears inline with your credentials ready to fill in one tap. You can also create and edit logins through it. New logins are automatically adapted to each site's own password rules, with the maximum strength password the site will accept being the default. It sounds like a small thing until you've used it every day.
Peach also knows every signup form isn't the same and it adapts. Some sites want just username and password, some username, email, and password, some email and totp. Whatever the combination Peach shows up prepared.

The rest

TOTP built in
Panic mode — one action, vault gone, irreversibly
Breach detection and weak password alerts
One-time purchase, no subscription, yours forever
Android coming very soon with iOS following in the coming months afterward
Password recovery built in through recovery words a user must write down and store.

Why it's not open source

Food costs money. I'm a solo developer with no funding and no team. The primitives are all standard and auditable — AES-256-GCM, Argon2id, BLAKE3, Noise NK — nothing proprietary between you and your data. A formal audit is on the roadmap when revenue supports it.

Oh and did I mention it pairs over ultrasonic audio?
