Can I vibecode 1Password?
KINDA · weekend projectA basic encrypted vault is buildable, but browser autofill, mobile apps, passkeys, sharing, recovery, audits, and trust make this a dangerous thing to replace casually.
Build me a local encrypted password vault to replace 1Password, CLI-first. Requirements: - A single-binary CLI in Go using filippo.io/age for encryption and Argon2id (golang.org/x/crypto) to derive the key from my master passphrase. Use the library primitives exactly as documented, invent no crypto. - The vault is one encrypted file at ~/.vault/vault.age holding JSON entries: name, username, password, URL, notes, updated timestamp. - Commands: add, get <name> (copies to clipboard, clears it after 20 seconds), ls, gen (32-char random password), edit, rm. - Fuzzy name matching on get; never print a password to stdout unless --show is passed. - vault backup writes a date-suffixed copy of the encrypted file to a folder set in .env; it is already encrypted, so any cloud drive can sync it. - Import from a 1Password CSV export so I can migrate in one command. - Everything local: no server, no accounts, no telemetry. - Out of scope: browser autofill, passkeys, and secure sharing. Those are why people pay 1Password; if I need them the honest move is KeePassXC or Bitwarden, say exactly that in the README. - README: a five-line threat model, how key derivation works, and a warning that losing the master passphrase loses everything, there is no recovery.

Can I vibecode 1Password?
Kinda. The core of 1Password is buildable in a weekend with the prompt on this page, but there are real gaps: browser/mobile autofill, passkey support. Read the honest list above before committing.
How much does 1Password cost?
1Password costs about $2.99/month (Individual, checked 2026-07-30), which is $35.88 per year.
What do I lose by replacing 1Password?
Honestly: browser/mobile autofill; passkey support; secure sharing; recovery; audits; watchtower alerts; family/team management. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to 1Password?
Yes: Vaultwarden (Passwords, passkeys, notes, sharing, and reports on your server; polished recovery support becomes your problem.) Bitwarden Free (Unlimited passwords, passkeys, secure notes, and one-person sharing; built-in TOTP and full reports cost extra.) The prompt is for when you want it exactly your way.
