Could you build this?
Partial Building a standard password manager UI is vibe-codeable, but implementing a zero-dependency, guaranteed cross-platform offline single-file decryptor using audited cryptographic primitives requires serious security engineering.
What it would actually take: A production version requires building an offline-first desktop/mobile client (e.g., Tauri, Swift/Kotlin) paired with an air-gapped standalone HTML/JS self-decrypting recovery container. The hard part is the cryptographic architecture: implementing PBKDF2/Argon2id, AES-GCM or ChaCha20-Poly1305, and BIP-39 mnemonic seed derivation correctly without memory leaks or timing vulnerabilities, requiring professional cryptographic security expertise.

Concerns raised: Manual password syncing across devices is a major friction point, Cloud storage is preferred by most users despite security trade-off, Unclear differentiation beyond local-only storage
Feature requests: Automatic cloud sync capability
