Best alternatives to Bramble in 2026

Most password managers store an encrypted copy of your vault on the company's servers, which is convenient for syncing across devices — but it also means a single breach at that company (which has happened to major password managers before) puts everyone's encrypted vaults in an attacker's hands at once. Bramble avoids that entirely: your vault stays encrypted on your own devices, and syncing happens directly between them. Bramble is a free, open-source (GPLv3) local-first password manager using AES-256-GCM encryption with Argon2id key derivation. Instead of a cloud server, it syncs across devices peer-to-peer, encrypted end-to-end over WebRTC, using a Nostr relay only to help devices find each other (the relay never sees your data). The same Rust crypto core powers browser extensions, iOS and Android apps, with native autofill and passkey creation/storage synced across devices — no account and no company vault to be breached.
